Fig. 1 shows a schematic diagram 100 of a modular circuit of the smart speaker of the present application.

As shown in fig. 1, the system architecture 100 may include a control module 101, a power module 102, and a plurality of functional modules, which are independent of each other, wherein the plurality of functional modules include a functional module 103, a functional module 104, and a functional module 105, and the control module 101 is communicatively connected to the power module 102 and the plurality of functional modules 103, 104, and 105 through connection lines, respectively; the control module 101 is configured to identify each of the plurality of function modules 103, 104, 105 by the power supply information of the plurality of function modules 103, 104, 105, and control the operation of the plurality of function modules 103, 104, 105.

The power module 102 is configured to supply power to the control module 101 and each function module, and the power supply parameter of each function module has uniqueness, for example, the current between each function module has uniqueness, and the control module 101 can identify each function module according to the current parameter of each function module. The control module 101 receives data of each functional module, and performs information analysis, processing, and synthesis on the received data to generate a control instruction fed back to a target functional module of the plurality of functional modules.

Each of the plurality of functional modules may implement one or more functions of the smart speaker. In some optional implementation manners of this embodiment, the plurality of functional modules include a recording module, a playback module, and a communication module that are independent of each other, and the recording module, the playback module, and the communication module are respectively in communication connection with the control module through connection lines.

The recording module is used for receiving the recording instruction of the control module and recording the audio. The recording module is internally integrated with an Analog to Digital Converter (ADC) chip, the Analog microphone array is used for collecting audio data, and the ADC chip is used for converting audio information into a standard Digital signal so as to realize the processing of the audio data by the control module. The ADC chip is controlled by the control module, and the main control module issues related commands or parameters.

The playback module is used for receiving playback instructions of the control module and playing audio. The playback module is internally integrated with a loudspeaker and a DAC (Digital to Analog Converter) chip. The digital audio signal generated by the main control module enters the DAC chip to be converted into an analog audio signal, and audio playing is carried out through the loudspeaker. The DAC chip is controlled by the control module 101, and the control module 101 issues related commands and parameters.

The communication module is used for receiving the communication instruction of the control module and communicating with a preset terminal. The preset terminal may be a hardware device or software supporting network connection for data interaction and data processing. When the preset terminal is hardware, it may be various electronic devices supporting functions of network connection, information interaction, display, processing, and the like, including but not limited to a smart phone, a tablet computer, an e-book reader, a laptop portable computer, a desktop computer, and the like.

In some optional implementations of this embodiment, the communication module employs at least one of the following communication modes: bluetooth, radio frequency, wireless broadband.

In some optional implementations of this embodiment, during the start-up process: the control module 101 determines a sender of the voltage information belonging to the voltage interval of the recording module as the recording module in response to determining that the received voltage information belongs to a preset voltage interval of the recording module, and sends first control information corresponding to the recording module; the control module responds to the fact that the received voltage information belongs to a preset playback module voltage interval, a sender of the voltage information belonging to the playback module voltage interval is determined as a playback module, and second control information corresponding to the playback module is sent to the playback module; the control module determines a sender of the voltage information belonging to the communication module voltage interval as the communication module and sends third control information corresponding to the communication module in response to determining that the received voltage information belongs to a preset communication module voltage interval. The voltage interval of the recording module, the voltage interval of the playback module and the voltage interval of the communication module are different.

In some optional implementation manners of this embodiment, the control module, the power supply module, and the plurality of functional modules are modules selected according to a product definition document of the smart sound box. The product definition document includes attribute information of the corresponding smart sound box, for example, information such as functions of the smart sound box, component signals, and the like. For a smart sound box product, before research and development, the corresponding control module, power module and functional modules can be selected according to various requirements in a product definition document, and the selected control module, power module and functional modules are assembled into the smart sound box.

In some optional implementations of the embodiment, the control module is further configured to reset the voltage intervals of the plurality of functional modules in response to determining that the modification instruction generated based on the product definition document of the smart sound box is received. Because the modules are arranged independently, the modules of the same type connected with the control module can be different modules aiming at the control module. For example, the playback modules connected with the control module can be playback modules with different functions and different output powers. Different modules within the same type of module may have different voltage intervals, and thus, the control module may need to reset the voltage intervals of the plurality of functional modules in response to determining that the modification instruction generated based on the product definition document for the smart sound box is received

In some optional implementations of the present embodiment, the input voltage of the power supply module is 5V-30V. The power supply module compatible with low voltage to high voltage is suitable for different use scenes, and the practicability is improved.
