Description
Technical field
The utility model relates to a kind of audio amplifier, particularly a kind of audio amplifier based on wireless technology.
Background technology
Existing audio amplifier is by power line and tone frequency channel wire mostly, connect in computer, TV or relevant electronic equipment, but because of circuit too much, unavoidably can give the sensation of a kind of numerous and complicated entanglement of people, from the putting position of wired audio amplifier certain angle also by restriction to a certain extent.Moreover existing wireless sound box is radio sound source signal can not be supported to input and wireless microphone signals input mostly simultaneously.
Utility model content
The purpose of this utility model is that to be to solve inconvenience when existing line audio amplifier uses and existing wireless sound box be radio sound source signal can not be supported to input and wireless microphone signals inputs simultaneously, and provides a kind of audio amplifier based on wireless technology.
The utility model to achieve these goals and adopt technical scheme be: a kind of audio amplifier based on wireless technology, comprise sound source module, described audio amplifier also comprises the wireless module of the sound source signal receiving sound source module, described wireless module transfers the sound source signal received to audio signal and passes to power amplifier module, described wireless module is also provided with wireless microphone interface end, and described power amplifier module passes to loud speaker after the audio signal received being amplified and releases.
Further, be also provided with reverberation module between described wireless microphone interface end and wireless module, described wireless microphone receiving terminal will receive human voice signal and pass to reverberation module, and the reverb signal after process is passed to wireless module by described reverberation module.
The beneficial effect of employing technique scheme is: wireless sound box of the present utility model supports radio sound source signal to input and wireless microphone signals input simultaneously.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
