[0024] In one embodiment, if Figure 1 As shown, the present application discloses a method for controlling a center speaker, which specifically includes the following steps: S10: Acquire an audio signal from an external sound source, and perform preliminary amplification processing on the audio signal from the external sound source to obtain a preliminary amplified audio signal.

[0025] In this embodiment, the audio signal of the external audio source refers to the audio signal from the external audio source. Specifically, the ultra-short-throw projector with a center speaker receives audio signals from external audio sources, such as mobile phones, computers, televisions and other devices, through its input interface.

[0027] Specifically, the audio signal has been preliminarily amplified by the pre-amplifier, and the level has been raised to a level suitable for further processing. To perform sound enhancement on the preliminarily amplified audio signal, it is necessary to analyze the characteristics of the audio signal, including frequency components, dynamic range, waveform, etc., in order to determine which sound effects processing needs to be applied. According to the characteristics of the audio signal and the target effect, the preliminarily amplified audio signal is subjected to corresponding sound enhancement to obtain an audio signal after sound enhancement.

Finally, according to the adjusted volume level, sound field positioning, dynamic range and other parameters, the enhanced and amplified audio signal is played through the corresponding built-in speakers, such as mono, stereo or multi-channel surround sound.

[0032] By adopting the above technical solution, the center speaker receives the audio signal from the external sound source through its input interface. The received audio signal is usually weak, so it needs to be initially amplified to increase its signal strength so that it meets the requirements of the internal processing circuit of the speaker, ensuring that the audio signal has sufficient strength before subsequent processing, which is beneficial to improving the sound quality and reducing noise interference; after the initial amplification, the audio signal will undergo a series of sound enhancement processing to optimize the sound quality according to the characteristics of the speaker, which helps to improve the listening quality of the audio, make the output audio more in line with the hearing habits of the human ear, and provide users with a richer and more layered listening experience; for the center speaker The system analyzes the environment and obtains the working environment data of the center speaker and the format of the audio signal after sound enhancement. According to the working environment data and the audio input format, the system determines the best output mode to ensure that the sound quality of the speaker output matches the playback environment, minimizes the negative impact of the environment on the sound quality, and makes full use of the performance of the speaker to provide users with the best listening experience; finally, according to the determined output mode, the audio signal after sound enhancement will be played through one or more built-in speakers of the center speaker, ensuring that the audio output method is most suitable for the current playback environment and content, providing a clear, three-dimensional and immersive listening experience.

[0049] Specifically, based on the collected audio data of the center speaker's surrounding environment and the analyzed audio input format, the output mode of the audio signal after sound enhancement is further analyzed and determined to find the best audio output setting to adapt to the current acoustic environment and audio signal characteristics.

[0050] In one embodiment, if Figure 6 As shown, in step S40, that is, according to the output mode of the audio signal after the sound effect is enhanced, the audio signal after the sound effect is enhanced is output through the corresponding built-in speaker, which specifically includes: S41: adjusting the output power and frequency response of each built-in speaker according to the output mode of the audio signal after the sound effect is enhanced, and selecting a suitable speaker array according to the characteristics of the audio signal after the sound effect is enhanced.

[0051] Specifically, based on the optimal playback configuration determined after the audio signal has been processed for sound enhancement, which may include stereo, surround sound or other multi-channel formats, the system will adjust the output power of each built-in speaker according to the requirements of the output mode to ensure the balance of volume and the appropriate sound pressure level. The system will also adjust the frequency response of the speaker and select the most suitable speaker array to optimize the playback effect based on the characteristics of the audio signal, such as dynamic range, frequency content and sound and image positioning.

[0052] S42: By real-time monitoring of the background noise level in the working environment, the output volume of the audio signal after sound enhancement is dynamically adjusted.
