Description

A kind of audio amplifier based on wireless technology
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.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the present invention, content of the present invention is further described.Example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, sound source module is comprised described in this programme, described audio amplifier also comprises the wireless module of the sound source signal receiving sound source module, in the present embodiment, described sound source module is smart mobile phone, flat board or notebook computer etc., and the sound source module described in this programme is smart mobile phone; Described wireless module transfers the sound source signal received to audio signal and passes to power amplifier module, and the wireless module described in the present embodiment is FM, RF or bluetooth etc., and what adopt in the present embodiment is Bluetooth technology; Described wireless module is also provided with wireless microphone interface end, reverberation module is also provided with between described wireless microphone receiving terminal and wireless module, the human voice signal received by wireless microphone is passed to reverberation module by described wireless microphone receiving terminal, described reverberation module is that the audio signal received from wireless microphone port is carried out rational reverberation; Reverb signal after process is passed to wireless module by described reverberation module; The sound source signal received and reverb signal are passed to power amplifier module by described wireless module, and described power amplifier module sends loud speaker to after the audio signal received being amplified and sends.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
