Abstract

The utility model discloses a kind of shockproof anti-interference audio amplifier, comprise casing, power amplifier, wireless transceiver; It is characterized in that: described box house is provided with power amplifier, power amplifier connects megaphone, and described megaphone is two, and box house is provided with wireless transceiver.Shockproof anti-interference audio amplifier of the present utility model has reliable operation, and easy to operate, operating efficiency is high, has the advantages such as shockproof decrease of noise functions, has very high practical value.

Description

A kind of shockproof anti-interference audio amplifier
Technical field
the utility model relates to a kind of audio amplifier, especially relates to a kind of shockproof anti-interference audio amplifier.
Background technology
audio amplifier is the terminal of whole sound system, and its effect is that audio frequency electric energy is converted to corresponding acoustic energy, and it is radiated space.It is the extremely important part of sound system, the signal of telecommunication is transformed into acoustical signal directly listens to so mission critical because which is responsible for the ear of people, it is wanted directly and the sense of hearing of people is come into contacts with, and the sense of hearing of people is very sensitive, and to the tone color of complex sound, there is very strong resolving ability.Because people's ear to evaluate the most important standard of a sound system tonequality quality just to the subjective feeling of sound, therefore, can think, the performance height of audio amplifier is play key effect to the playing quality of a sound system.
audio amplifier refers to a kind of equipment that audio signal can be transformed to sound.Popular saying just refers in speaker main casing or subwoofer casing and carries power amplifier, goes out sound, make its sound become large to audio signal after carrying out amplification process by the playback of audio amplifier own.At present, the function of loudspeaker box on market is single, can not meet the need of market.
Utility model content
the purpose of this utility model is to provide one and has structure simply, and reliable operation, easy to operate, operating efficiency is high, has the shockproof anti-interference audio amplifier of one of the advantages such as shockproof decrease of noise functions.
in order to realize the purpose of this utility model, the utility model is achieved through the following technical solutions: a kind of shockproof anti-interference audio amplifier, comprises casing, power amplifier, wireless transceiver; It is characterized in that: described box house is provided with power amplifier, power amplifier connects megaphone, and described megaphone is two, is provided with shockproof clay between described megaphone and cabinet panel; Between described casing, a junction is equipped with shockproof clay.
operation principle: shockproof clay is added in each junction of casing, reducing sound column is the resonance produced in work, eliminates mechanicalness noise, purification tonequality volume; And pronunciation vibrations can significantly decline by the shockproof clay between megaphone and cabinet panel, reduce power amplifier unofficial biography vibration frequency simultaneously, effectively reduce mechanicalness noise and impurity.
shockproof anti-interference audio amplifier of the present utility model has reliable operation, and easy to operate, operating efficiency is high, has the advantages such as shockproof decrease of noise functions, has very high practical value.
Accompanying drawing explanation
accompanying drawing 1 is the utility model structural representation.
in accompanying drawing: 1-casing, 2-megaphone, the shockproof clay of 3-.
embodiment:
embodiment 1
a kind of shockproof anti-interference audio amplifier, comprises casing 1, power amplifier, wireless transceiver 3; It is characterized in that: described casing 1 inside is provided with power amplifier, power amplifier connects megaphone 2, and described megaphone 2 is two, is provided with shockproof clay 3 between described megaphone 2 and cabinet panel; Between described casing, each junction is equipped with shockproof clay 3.
embodiment 2
utility model works principle: shockproof clay 3 is added in each junction of casing 1, reducing sound column is the resonance produced in work, eliminates mechanicalness noise, purification tonequality volume; And pronunciation vibrations can significantly decline by the shockproof clay 3 between megaphone 2 and casing 1 panel, reduce power amplifier unofficial biography vibration frequency simultaneously, effectively reduce mechanicalness noise and impurity.
