Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a channel switching method according to an embodiment of the present invention, where the channel switching method is applied to a first electronic device, and the first electronic device is connected to a second electronic device, for example, through a wired connection or a wireless connection, such as a bluetooth connection or a WIFI connection. The first electronic device is an audio transmission device, such as a mobile phone, a computer, a tablet computer and the like; the second electronic device is an audio playing device, such as an earphone, a sound device, and the like.

As shown in fig. 1, the channel switching method includes the steps of:

step 101, obtaining a left channel audio signal and a right channel audio signal.

It is understood that the left channel audio signal and the right channel audio signal may be audio signals to be played or being played by the first electronic device. For example, when the first electronic device receives a touch operation performed by a user on a music play button, the first electronic device plays audio, and the first electronic device can decode the played audio into a left channel audio signal and a right channel audio signal.

And 102, under the condition that the second electronic equipment is in a first wearing state, coding the left channel audio signal and the right channel audio signal according to a first coding sequence and then sending the coded signals to the second electronic equipment.

Optionally, the second electronic device is an earphone, the earphone includes a left earphone and a right earphone, and the wearing state of the earphone is related to the wearing positions of the left earphone and the right earphone. For example, in the first wearing state, the left earphone is worn on the left ear, and the right earphone is worn on the right ear; in the second wearing state, the left earphone is worn on the right ear, and the right earphone is worn on the left ear.

In the embodiment of the invention, the first electronic device acquires that the earphone is in the first wearing state, so that the wearing positions of the current left earphone and right earphone can be known, the left channel audio signal and the right channel audio signal can be coded according to the first coding sequence according to the wearing positions of the left earphone and the right earphone, and the coded left channel audio signal and the coded right channel audio signal are sent to the earphone, so that the right channel audio is heard by the right ear of a user, the left channel audio is heard by the left ear, and the better listening experience of the user is ensured.

For example, if the left earphone is worn on the left ear and the right earphone is worn on the right ear in the first wearing state, the first electronic device encodes the left channel audio signal and the right channel audio signal according to the first encoding sequence, so that the left earphone receives the left channel audio signal and the right earphone receives the right channel audio signal. If the left earphone is worn on the right ear and the right earphone is worn on the left ear in the second wearing state, the first electronic device encodes the left channel audio signal and the right channel audio signal according to the first encoding sequence, the left earphone receives the right channel audio signal, and the right earphone receives the left channel audio signal. Therefore, the user can be ensured to have better listening experience.

It should be noted that, before the step 102, the method may further include: and acquiring the wearing state of the second electronic equipment, namely acquiring the wearing positions of the left earphone and the right earphone. Optionally, the left earphone and/or the right earphone may be provided with an infrared sensor, and the first electronic device determines the wearing position of the left earphone and the wearing position of the right earphone by receiving an infrared signal of the infrared sensor. For example, the infrared sensor is arranged on the left earphone, when the left earphone is worn on the left ear, the infrared sensor is in an exposed state, the infrared signal cannot be blocked, and if the left earphone is worn on the right ear, the infrared sensor is close to the helix, and the infrared signal emitted by the infrared sensor is reflected by the helix; the first electronic device may determine a wearing position of the left earphone by detecting a time length for receiving the infrared signal, determine that the left earphone is worn on the left ear if the infrared signal is received within a preset time length, and determine that the left earphone is worn on the right ear if the infrared signal is not received within the preset time length. Of course, the first electronic device may also detect the wearing positions of the left and right earphones by other methods, such as a gravity sensor and an angle sensor, which are not described in detail in this embodiment of the present invention.

And 103, under the condition that the second electronic equipment is in a second wearing state, coding the left channel audio signal and the right channel audio signal according to a second coding sequence and then sending the coded signals to the second electronic equipment.

Wherein, in the first coding sequence, the left channel audio signal and the right channel audio signal are alternately arranged, and the left channel audio signal is located at a first position; in the second coding sequence, the left channel audio signal and the right channel audio signal are alternately arranged, and the right channel audio signal is located at the first position.

It should be noted that, in the first coding sequence and the second coding sequence, the left channel audio signal and the right channel audio signal are alternately arranged. For example, referring to fig. 1a, in a first coding sequence a1, a left channel audio signal and a right channel audio signal in a frame of audio are coded in the order of left, right, and left; referring to fig. 1b, in the second coding sequence a2, a left channel audio signal and a right channel audio signal in a frame of audio are coded in the order of right, left, and right; wherein, a frame of audio also comprises a delay signal. Alternatively, a plurality of (or one) left channel audio signals as a whole may be alternately arranged with a plurality of (or one) right channel audio signals as a whole, for example, one frame of audio is all left channel audio signals, the next frame of audio is all right channel audio signals, and the next frame of audio is all left channel audio signals … ….

In order to better describe the solution of the embodiment of the present invention, the following description will specifically describe that the second electronic device is an earphone, and the earphone includes a left earphone and a right earphone. Wherein, in the first wearing state, the left earphone is worn on the left ear, and the right earphone is worn on the right ear; in the second wearing state, the right earphone is worn on the left ear, and the left earphone is worn on the right ear.

Therefore, when the headset is in the first wearing state, the left headset is worn on the left ear, the right headset is worn on the right ear, and the first electronic device encodes the left channel audio signal and the right channel audio signal according to the first encoding sequence, so that the left headset receives the left channel audio signal, and the right headset receives the right channel audio signal. When the earphone is in the second wearing state, the left earphone is worn on the right ear, the right earphone is worn on the left ear, the first electronic device encodes the left channel audio signal and the right channel audio signal according to the second encoding sequence, the left earphone receives the right channel audio signal, the right earphone receives the left channel audio signal, the right earphone still receives the right channel audio, and the left earphone still receives the left channel audio. Therefore, even if the wearing positions of the earphones are not right, the earphones do not need to be replaced by a user, the left ear still hears the left channel audio, and the right ear still hears the right channel audio, so that the listening experience of the user is ensured, and the user operation is simplified.

In this embodiment of the present invention, after the step 101, the method may further include:

acquiring a preset coding duration for coding the left channel audio signal and the right channel audio signal by the first electronic device;

splitting the left channel audio signal and the right channel audio signal into a plurality of first left channel audio signals and a plurality of first right channel audio signals meeting the preset coding duration respectively;

in this case, the step 102 includes:

under the condition that the second electronic equipment is in a first wearing state, configuring the first left channel audio signal at a first preset position in a first coding sequence, configuring the first right channel audio signal at a second preset position, coding a plurality of first left channel audio signals and a plurality of first right channel audio signals according to the first coding sequence, and then sending the coded signals to the second electronic equipment;

the step 103 comprises:

under the condition that the second electronic equipment is in a second wearing state, the first left channel audio signal is configured at the second preset position in a second coding sequence, the first right channel audio signal is configured at the first preset position, and the plurality of first left channel audio signals and the plurality of first right channel audio signals are coded according to the second coding sequence and then are sent to the second electronic equipment.

The preset coding duration is duration of a frame of audio, or the preset coding duration is duration of a signal time slot. For example, the preset coding duration is a duration of a signal timeslot, and then one coding duration corresponds to one first left channel audio signal or one first right channel audio signal. Assuming that one frame of audio includes 5 channel audio signal slots and one delay signal slot, one frame of audio also includes 5 channel audio signals; as shown in fig. 1a, in the first coding sequence, 5 channel audio signals included in one frame of audio are respectively a first left channel audio signal, a first right channel audio signal, and a first left channel audio signal, and are sequentially ordered; as shown in fig. 1b, in the second coding sequence, the 5 channel audio signals included in one frame of audio are respectively a first right channel audio signal, a first left channel audio signal, and a first right channel audio signal, and are sequentially ordered. Thus, the coding position of the left channel audio signal in the first coding sequence corresponds to the coding position of the right channel audio signal in the second coding sequence, and the coding position of the right channel audio signal in the first coding sequence corresponds to the coding position of the left channel audio signal in the second coding sequence. It should be noted that the first preset position of the first left channel audio signal configuration is the first position in the first coding sequence; the first preset position of the first right channel audio signal configuration is said first position in the second encoded sequence.

Or, when the encoding duration is the duration of one frame of audio, then the one frame of audio is all left channel audio, or all right channel audio. For example, assuming that the target audio transmitted by the first electronic device includes 3 frames of audio, in the first encoding sequence, a plurality of first left channel audio signals are configured in the first frame of audio and the third frame of audio, and a plurality of first right channel audio signals are configured in the second frame of audio; and configuring a plurality of first right channel audio signals in the first frame audio and the third frame audio and configuring a plurality of first left channel audio signals in the second frame audio in the second coding sequence. In this case, the first position is also the position of the first frame of audio.

In the embodiment of the invention, first electronic equipment acquires a left channel audio signal and a right channel audio signal; under the condition that the second electronic equipment is in a first wearing state, the left channel audio signal and the right channel audio signal are coded according to a first coding sequence and then are sent to the second electronic equipment; under the condition that the second electronic equipment is in a second wearing state, the left channel audio signal and the right channel audio signal are coded according to a second coding sequence and then are sent to the second electronic equipment; wherein, in the first coding sequence, the left channel audio signal and the right channel audio signal are alternately arranged, and the left channel audio signal is located at a first position; in the second coding sequence, the left channel audio signal and the right channel audio signal are alternately arranged, and the right channel audio signal is located at the first position. Therefore, the first electronic equipment can automatically complete the switching between the left channel audio and the right channel audio according to the wearing state of the second electronic equipment without changing the wearing state of the second electronic equipment by a user, so that the left channel audio can be still heard by the left ear of the user, the right channel audio can be still heard by the right ear of the user, the user can be guaranteed to have better listening experience, and the user operation is simplified.

Referring to fig. 2, fig. 2 is a flowchart of another sound channel switching method according to an embodiment of the present invention, where the sound channel switching method is applied to a second electronic device, and the second electronic device is connected to a first electronic device, for example, through a wired connection or a wireless connection, such as a bluetooth connection. The first electronic device is an audio transmission device, such as a mobile phone, a computer, a tablet computer and the like; the second electronic device is an audio playing device, such as an earphone, a sound device, and the like.

As shown in fig. 2, the channel switching method includes the steps of:

step 201, receiving an audio signal sent by a first electronic device.

It is understood that the second electronic device can receive the audio signal transmitted by the first electronic device when connected with the first electronic device. The audio signals comprise coded left channel audio signals and right channel audio signals.

Step 202, decoding the audio signal into a left channel audio signal and a right channel audio signal according to a first decoding sequence under the condition that the second electronic device is in the first wearing state.

In order to better describe the solution of the embodiment of the present invention, the following description will specifically describe that the second electronic device is an earphone, and the earphone includes a left earphone and a right earphone. Wherein, in the first wearing state, the left earphone is worn on the left ear, and the right earphone is worn on the right ear; in the second wearing state, the right earphone is worn on the left ear, and the left earphone is worn on the right ear.

It can be understood that, when the earphone is in the first wearing state, that is, the left earphone is worn on the left ear of the user, and the right earphone is worn on the right ear, the earphone decodes the received audio signal into the left channel audio signal and the right channel audio signal according to the first decoding sequence, so that the left earphone receives the left channel audio signal, and the right earphone receives the right channel audio signal. Therefore, the left ear of the user can hear the left channel audio, and the right ear can hear the right channel audio, so that the user can enjoy better listening experience.

It should be noted that the earphone may be a left earphone or a right earphone for receiving the target audio. For example, the target audio sent by the first electronic device is received by the left earphone, and the left earphone decodes the received target audio to obtain a left channel audio signal and a right channel audio signal, and can send the right channel audio signal to the right earphone.

Step 203, decoding the audio signal into the left channel audio signal and the right channel audio signal according to a second decoding sequence when the second electronic device is in a second wearing state.

Wherein, in the first decoding sequence, the left channel audio signal and the right channel audio signal are alternately arranged, and the left channel audio signal is located at a first position; in the second decoding sequence, the left channel audio signal and the right channel audio signal are alternately arranged, and the right channel audio signal is located at the first position. For example, in the first decoding sequence, the left channel audio signal and the right channel audio signal may be decoded in the order of left, right, left, right … …, and in the second decoding sequence, the left channel audio signal and the right channel audio signal are decoded in the order of right, left, right, left … ….

When the earphone is in the second wearing state, the left earphone is worn on the right ear, the right earphone is worn on the left ear, and the earphone decodes the received audio signals into left channel audio signals and right channel audio signals according to the second decoding sequence, so that the left earphone receives the right channel audio signals, and the right earphone receives the left channel audio signals. Therefore, the left ear of the user still hears the left channel audio, and the right ear still hears the right channel audio, so that the user can enjoy better listening experience.

It should be noted that, the earphone may set the corresponding decoding rule by obtaining the encoding rule of the audio signal by the first electronic device. In the embodiment of the present invention, the earphone may acquire a first encoding rule and a second encoding rule of the first electronic device, and further set a corresponding first decoding rule according to the first encoding rule and set a corresponding second decoding rule according to the second encoding rule; under the first decoding rule, the first electronic equipment encodes the left channel audio signal and the right channel audio signal according to a first encoding sequence, and under the second decoding rule, the left channel audio signal and the right channel audio signal are encoded according to a second encoding sequence.
