Embodiment
Sound inlet herein is appreciated that：On broadcaster shell and for the logical of microphone collection external audio
Road.
In the present embodiment, broadcaster is by taking audio amplifier as an example, with Packed shell on the audio amplifier, is provided with shell for microphone
Gather the sound inlet of external audio.Enclosure is provided with processor, dio Output Modules and multiple microphones.Dio Output Modules
Electrically connected with processor, so as to realize broadcast.Multiple microphones are respectively electrically connected to processor, and collection is same jointly for multiple microphones
One section audio, reapply multi-microphone Data fusion technique multiple audios of collection are merged, with obtain distortion compared with
A small audio, then the audio is used to test so as to improve the accuracy of test.Computer is additionally provided with casing of loudspeaker box can
Storage medium is read, the computer program of the sealing for judging broadcaster is stored with the medium, the program can be in processor
Upper execution.
When carrying out performing leak test to audio amplifier, first audio amplifier is placed at one, playback set is then placed on distance
Audio amplifier 0.5m place simultaneously commences play out the most common pink noise of nature, i.e. external audio H, due to pink noise frequency point
Amount power is mainly distributed on middle low-frequency range, and the frequency range often played with audio amplifier is overlapping, therefore is tested with pink noise and most have
It is representative.And adjusted by the distance of playback set and audio amplifier so that when the pink noise that playback set plays is arrived at audio amplifier,
The sound intensity of pink noise is about 90dBc, and sound was both not too large so as to produce sonic boom with disturbed test, again will not it is too small so that
Test meaningless.After pink noise arrives at audio amplifier, it is transferred on the microphone of audio amplifier through sound inlet, and is distinguished by multiple microphones
It is acquired jointly through multiplex (MUX), the multiple audios collected carry out fusion treatment by processor again, to obtain audio A.
