Technical field

The invention relates to the technical field of sound boxes, in particular to a multifunctional modular speaker.

Background technique

At present, the audio-visual system on the market has a single function. If you want to listen to HiFi high-fidelity music, you must have a HiFi stereo. If you want to experience the sound quality of home theater and game play, you must have a home theater audio, you want karaoke. At the same time, there must be a set of karaoke audio (including high-power post-amplifiers, effects, karaoke speakers, karaoke machines, wireless microphones). For an audio-visual enthusiast, there may be several sets of different needs in the living room. Equipment, even master bedroom, study, kitchen, although this approach meets the requirements for different needs, but the price is expensive, the wiring is complicated, and even the pipeline must be laid in advance, the professional requirements are also very high, non-professionals can not Debugging, due to these limitations, it is not as popular as a smartphone. A music enthusiast who is just getting started, even in the face of a wide range of audio-visual equipment on the Internet, can't even pick it. Nowadays, the rapid development of technology, smart phones/tablets already have High quality digital media playback and entertainment features, internet box and internet Video cameras are also equipped with digital media and entertainment functions, providing high-definition TV programs, 4K movies and high-definition audio-visual entertainment. In the near future, various mobile terminal devices and Internet terminal devices are high-quality audio and video playback devices. Game entertainment equipment, which provides various audio and video media and entertainment directly from the cloud, and spreads to every home and every terminal device. At the same time, it must have the same multi-functional audio-visual equipment that can be popularized, and has the following points. feature:

Ability to integrate multiple audiovisual features.

It is possible to select/replace/adjust the required functions, speaker units, decorative accessories, etc. according to user needs.

With HiFi high-fidelity sound quality, it can also have the shocking effect of K-song, cinema, and game dynamics.

It is small in size and can be easily moved between the room and the living room.

No need to connect and hang, nor need to pre-wire.

The operation is simple and easy for most people to operate.

The price is reasonable, like a smartphone, it can be popularized by everyone.

Therefore, how to develop an audiovisual device having the above various features is a major problem to be solved by those skilled in the art.

Summary of the invention

In view of the deficiencies in the prior art, the present invention designs the speaker as a modular structure, and designs various functions of the audio-visual device into various modules, such as an active power amplifier module, an active bass module, a wireless interconnection module, and digital audio decoding. Module, dynamic sound quality compensation processing module, CD/DVD player module, reverberation module, wireless microphone module, internet box module, touch display module, intelligent voice module, various sensors and control modules of smart home, etc. The design method can achieve the following advantages:
