Abstract
The utility model discloses a high fidelity acoustic transmission sound box comprising an audio frequency amplifier connected with an output end of an audio signal output device. A signal output end of the audio frequency amplifier is connected with a signal input end of a loudspeaker. The sound box is connected with the audio frequency signal output device by adopting the wireless communication technology. A wireless signal receiving module is disposed in the sound box, and a wireless signal transmitting module is disposed in the audio frequency output device. The high fidelity acoustic transmission sound box is advantageous in that the tedious wired connection can be saved by adopting the wireless connection technology, and at the same time, the distortion of the sound box is low, and the signal to noise ratio is high.
Description
Technical field
The utility model relates to the transaudient sound equipment of a kind of high-fidelity.
Background technology
Existing stereo set comprises audio signal amplifier and loud speaker, sound equipment is connected by wired with the output of audio signal, when the required sound equipment in room is more and when distant with audio signal output end, connecting line is many and numerous and diversely not only take up room, simultaneously, also can cause both poor sound quality, signal to noise ratio is low, and the loss of signal is also large.
The utility model content
The purpose of this utility model solves the problems of the technologies described above, and proposes the transaudient sound equipment of a kind of high-fidelity.
The purpose of this utility model will be achieved by the following technical programs:
The transaudient sound equipment of high-fidelity, comprise the audio frequency amplifier be connected with the output of audio signal output device, the signal output part of described audio frequency amplifier is connected with the signal input part of loud speaker, between described sound equipment and audio signal output device, by wireless communication module, be connected, be provided with the reception of wireless signals module in described sound equipment, be provided with the wireless signal sending module in described audio signal output device.
Preferably, described channel radio module is wireless receiving/reflector or bluetooth module.
The beneficial effects of the utility model are mainly reflected in: by wireless connections, saved the loaded down with trivial details of wired connection, simultaneously, the distortion of sound equipment is low, and signal to noise ratio is high.
The accompanying drawing explanation
Fig. 1: structural representation of the present utility model.
Embodiment
