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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

The invention mainly comprises a data acquisition unit for acquiring the action data of a player, a control conversion unit for converting the corresponding action data into corresponding audio, and a pronunciation unit for pronouncing according to the audio data. The data acquisition unit transmits the motion data to the control conversion unit after acquiring the motion data of the player, the control conversion unit analyzes and converts the motion data into corresponding audio data and then transmits the audio data to the pronunciation unit, and the pronunciation unit pronounces according to the received audio data. The data acquisition unit, the control conversion unit and the pronunciation unit can be in physical and electrical connection or in wireless connection.

In a first embodiment, as shown in fig. 1, the data acquisition unit is integrated with the control scaling unit, and the control scaling unit is wirelessly connected with the pronunciation unit.

In this embodiment, the data acquisition unit includes an electronic gyroscope and an electronic accelerometer that operate independently. The electronic gyroscope measures an included angle between a vertical axis of a gyroscope rotor in a three-dimensional coordinate system and equipment, calculates an angular velocity, and judges the motion state of an object in a three-dimensional space through the included angle and the angular velocity; the accelerometer sensor works based on the basic principle of acceleration, can measure the space acceleration, and can comprehensively and accurately reflect the motion property of an object. Therefore, the player's motion data includes three indexes of the spatial angle, the angular velocity, and the spatial acceleration. And the data acquisition unit transmits corresponding data to the control conversion unit after the acquisition is finished.

In the control conversion unit, the mapping relationship between the motion data and the audio data needs to be preset, and the corresponding "do", "re", "mi", "fa", "sol", "la" and si "in the music score is represented by an arabic numeral" 1234567 ". The custom settings may be: setting the horizontal movement from the origin to the left and returning to the origin as "1", the horizontal movement from the origin to the right and returning to the origin as "2", the vertical movement from the origin to the top and returning to the origin as "3", the vertical movement from the origin to the bottom and returning to the origin as "4", the circle drawn clockwise on the horizontal plane as "5", the circle drawn counterclockwise on the horizontal plane as "6", and the circle drawn clockwise or counterclockwise on the vertical plane as "7". A mapping relation table corresponding to the action and the note can also be set, such as a Sudoku, and a player holds the equipment to reciprocate from the original point to the left, right upwards, right leftwards, right rightwards, left downwards and right downwards, and respectively represents '1', '2', '3', '4', '5', '6' and '7'. In the control conversion unit, the spatial included angle, the angular velocity and the spatial acceleration are converted into corresponding audio data, and then the audio data are transmitted to the pronunciation unit.

In this embodiment, the data acquisition unit and the control conversion unit are built in the wearable device such as a watch and a bracelet, and can also be arranged in the handheld device such as a baton. Since the data acquisition unit mainly acquires the motion data of the player, particularly the hand motion data, other devices or apparatuses meeting the requirements can also be applied. In this embodiment, the wearable device or the handheld device is provided with a plurality of keys for adjusting the tone height. In a specific embodiment, the control scaling unit employs a single-chip microcomputer. The control conversion unit and the pronunciation unit are connected in a common wireless connection mode such as Wifi connection, Zigbee connection or BT connection.

The pronunciation unit may employ a pronunciation instrument with an audio output subsystem and a speaker. And after receiving the audio data of the control conversion unit, the pronunciation unit calls the output parameters of the corresponding musical instrument to make the loudspeaker send out corresponding music. In a specific embodiment, the sound generation unit may be a mobile phone, a tablet, a smart speaker, etc. with a corresponding software program.

The music mainly comprises loudness, tone and timbre, wherein in the invention, the loudness can be adjusted by the pronunciation unit to the intensity of the output sound, and the timbre can be adjusted according to the instrument selected in the pronunciation unit; the final heard tone is correspondingly output by the action acquisition unit, so that the input mode of the traditional musical instrument is changed.

In a second embodiment, as shown in fig. 2, the control conversion unit is integrated with the pronunciation unit, and the data acquisition unit is wirelessly connected with the control conversion unit. In this embodiment, the external sound generation unit may be output by using a terminal such as a mobile phone, a tablet, a sound box, etc. The second embodiment has higher product stability and lower production cost than the first embodiment.

In the third embodiment, the data acquisition unit, the control conversion unit and the pronunciation unit are integrated integrally and are arranged in a watch strap, a bracelet or a baton. In this embodiment, the data is not transmitted in a wireless manner, the data acquisition unit is an electronic gyroscope and an electronic accelerometer, the control conversion unit is a PCB, and the sound generation unit can be a sound generation structure such as a speaker. The action data are collected by the data acquisition unit, converted into electric signals by the PCB, and converted into corresponding acoustic signals by the loudspeaker for output. The third embodiment is higher in structural integration than the first embodiment or the second embodiment, but the speaker is in an unstable state as the player moves, and affects the sense of hearing.

The method comprises the following steps: 1. presetting a corresponding relation between actions in the control conversion unit and audio; 2. selecting timbres corresponding to different musical instruments at the sound pitch; 3. the music performance can be started by wearing the wearable equipment with the data acquisition unit or holding the handheld device with the data acquisition unit, and the volume can be properly adjusted at the pronunciation unit during the performance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
