[0042] The first speaker 8, the second speaker 9, and the third speaker 10 are arranged in a triangular array on the front surface of the enclosure 1. Compared with a single speaker, this can effectively improve the sound coverage and reduce sound blind spots. Moreover, the phase inefficiency and enhancement of the sound waves of each speaker in space can improve the clarity of the sound and enhance the user experience.

[0043] like Figure 5 As shown, in this embodiment, a processing module 11 and a control circuit 12 are provided between the voice recognition module 3 and the main control module 4. The output terminal of the voice recognition module 3 is connected to the input terminal of the processing module 11, the output terminal of the processing module 11 is connected to the input terminal of the control circuit 12, and the output terminal of the control circuit 12 is connected to the input terminal of the main control module 4.

[0047] A set of transistors (four transistors in this embodiment) is placed between the voice recognition module 3 and the main control module 4, acting as electronic switches. When the voice recognition module outputs a high-level signal, the transistors saturate and conduct, connecting the power supply, signal, or output path of the main control module, improving the convenience and accuracy of control. Furthermore, the control circuit composed of transistors also provides isolation, preventing reverse current from impacting the voice recognition module, improving the safety and reliability of the audio circuit, and effectively reducing circuit power consumption, which helps extend the audio system's lifespan and reduce its size.

Pin 2 of the main control module 4, pin 10 of the speaker driver module, and pin 1 of the second spectrum display component 6 are connected in series. Output pins 13 and 14 of the speaker driver module are connected to the second speaker 9, and output pins 15 and 16 of the speaker driver module are connected to the third speaker 10. The first spectrum display component 5 and the second spectrum display component 6 are respectively connected to a power supply.

[0051] This embodiment incorporates a voice recognition module, a processing module, and a control circuit, working in conjunction with a main control module and a speaker connected to the main control module to achieve voice interaction. This voice interaction circuit boasts high signal transmission accuracy, improving the accuracy of voice recognition and transmission, and facilitating operation. Through voice interaction, coupled with intuitive displays of usage information, precise adjustments can be made, enhancing the ease of use of the audio system. The specific implementation of voice recognition by the module is a conventional technique and will not be elaborated upon in this embodiment.

[0052] In this embodiment, the display component also includes a power switch 13 and a signal switch 14.

The dust filters at the speaker outlets filter the speaker's input, preventing particles and fibrous impurities from entering the speaker, damaging it, causing noise and sound distortion, and reducing physical wear and tear, thus extending its service life.

[0055] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort.
