Description
Technical field
The utility model relates to wireless audio devices, in particular to a kind of wireless audio transfer processor.
Background technique
Because launching apparatus for radio microphone is to carry on the person for a long time, transmitter space wants small, and weight is not yet
It can be overweight.Small-capacity cells can only be selected by resulting in.It is long using the time because of performance simultaneously, limit transmitter RF signal transmission power
Cannot be too big, (power is excessive, and battery capacity will soon be out of power, and client is unacceptable), while because using low-voltage power supply
(1.5 volts of batteries of such as 2 section or 3.7 volts of lithium batteries), voltage is low to also limit transmission power.A-battery guarantees length again simultaneously
Time uses, so can only emit small-power, leads to emit square from close, a little further square from place, often there is disconnected frequency, break
Sound, interference string frequency, or even the case where directly can not receive signal, be unable to satisfy remote square from use occasion (such as school playground, it is large-scale to wave
Platform, wedding celebration interaction, construction site, megastore, the remote square such as large conference room are left the theatre institute).
And conventional wireless microphone, it is in the single position in receiving end to audio processing and control, because place is different, places position
It is different to set different, control mode difference, source of sound access way, it has not been convenient to it is mobile, it is difficult multiposition and drives multiple power amplifiers, Bu Nengduo
To audio processing and control, traditional method is the extension lengthened with the extended line of power amplifier sound equipment, lengthening receiver to power amplifier for position
Line.Lengthening audio extended line will lead to impedance variations, audio distortions.Traditional extended line mode wire rod is at high cost, and installation is complicated, palpus
Specialized engineering personnel's installation and debugging, and bracing wire influences to build beautiful, engineering time-consuming, and installation and debugging are at high cost, it has not been convenient to
Unsightly.
