Detailed description of the invention
For the ease of the understanding of those skilled in the art, this utility model is made further with accompanying drawing below in conjunction with embodiment
Explanation, the content that embodiment is mentioned is not to restriction of the present utility model.Below in conjunction with accompanying drawing, this utility model is carried out
Detailed description.
A kind of novel passive irradiator audio amplifier provided by the utility model, including sound box body, speaker and passive
Irradiator, described speaker and passive radiator are respectively arranged at the inner chamber of described sound box body, described speaker and passive spoke
The ventilating buffering layer 6 that air-flow is produced cushioning effect it is provided with between emitter.Preferably, described ventilating buffering layer 6 is spongy layer
Or screen cloth.The shape of ventilating buffering layer 6 does not limits, and can be square or round or other arbitrary shapes, according to sound in actual application
The shape of case is arranged.Ventilating buffering layer 6 is not limited to sponge or screen cloth, as long as the effect of buffer gas flow can be played, it is possible to so that
Substitute with other gas permeable materials, depending on the permeability of material is according to the concrete debugging situation of audio amplifier.In this utility model, sea
Continuous layer is the optimum selection material of ventilating buffering layer 6, and spongy layer can weaken the casing resonance caused by standing wave, is equivalent to sound at ordinary times
Case is filled the effect of acoustical cotton.
