Sound can not be controlled when in use, for this purpose, it is proposed that a kind of microphone volume self-checking device.
Utility model content
The main purpose of the utility model is that providing a kind of microphone volume self-checking device, pass through heat-sensitive sensor
The heat distributed in user mouthful is sensed, the distance of microphone and user's oral area is calculated by step with holes, is led to
Crossing control electric current makes magnet change the power in magnetic field, and microphone is made to have the characteristics that low in energy consumption, dynamic range is big, makes user's
The sound sent in certain distance can be transferred out by stable, current sound, bottom when can reduce use by denoiser
What is generated when making an uproar, recording gives a tongue-lashing sound etc. noise, makes acquisition more usage experience, is suitble to be widely popularized and used, can be with
Effectively solve the problems, such as in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of microphone volume self-checking device, it is described including housing, protective cover, switch, signal projector and battery
Case top is removably connected with protective cover, and the switch is located at one side surface of housing, and the signal projector is located in housing
Chamber, the battery are located at signal projector bottom, and the protective cover inner cavity is fixedly installed vibrating diaphragm, and the vibrating diaphragm both sides are fixed and set
Voice coil is equipped with, the voice coil one side is fixedly installed heat-sensitive sensor, and the heat-sensitive sensor bottom is fixedly installed field-effect
Pipe, the field-effect tube bottom are fixedly installed magnet, and the magnet bottom is fixedly installed denoiser.
Further, described denoiser one end is fixedly connected with transformer.
Further, the signal projector bottom is connected with anode, passes through audio at the top of the signal projector
Line is connected with transformer.
Further, the magnet one side is fixedly installed step with holes.
Further, the transformer is step-up transformer.
Compared with prior art, the utility model has the advantages that：
1. microphone is powered by battery, and passes through switch and the opening and closing of microphone are controlled, pass through
The protective cover at top can protect the electronic original part inside microphone, while protective cover can reduce due to blowing or moving biography
The pneumatic noise of bursting generated during sound device, can decay the noises such as generated ability to speak, breathing when closely talking, additionally it is possible to prevent
Dust enters microphone, influences the normal use of microphone.
2. when in use, when on sound wave effect to vibrating diaphragm, vibrating diaphragm drives voice coil to make phase in magnetic field caused by magnet
It should vibrate, so as to cutting magnetic line, voice coil both ends will generate induced electromotive force, and then sound wave is just converted into corresponding audio
Electric signal since the electromotive force of voice coil output is very weak, it is necessary to boost by step-up transformer to audio signal, and passes through letter
Number transmitter passes audio signal.
3. sensing by heat-sensitive sensor to the heat distributed in user mouthful, Mike is calculated by step with holes
The distance of wind and user's oral area, and pass through and control electric current that magnet is made to change the power in magnetic field, and pass through and combined with field-effect tube,
Microphone is made to have the characteristics that noise is small, low in energy consumption, dynamic range is big, be easily integrated, makes being sent out in certain distance for user
The sound gone out can be transferred out by stable.
4. what is generated when current sound, bottom make an uproar, record when can reduce use by denoiser gives a tongue-lashing sound etc. noise, make acquisition
More usage experience.

Specific embodiment
Technical means, creative features, achievable purpose and effectiveness to realize the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figs. 1-2, a kind of microphone volume self-checking device, including housing 1, protective cover 2, switch 3, signal hair
Emitter 4 and battery 5,1 top side detachable of housing are connected with protective cover 2, and the switch 3 is located at 1 one side surface of housing, described
Signal projector 4 is located at 1 inner cavity of housing, and the battery 5 is located at 4 bottom of signal projector, 2 inner cavity of the protective cover fixed setting
There is vibrating diaphragm 6,6 both sides of vibrating diaphragm are fixedly installed voice coil 7, and 7 one side of voice coil is fixedly installed heat-sensitive sensor 12, described
12 bottom of heat-sensitive sensor is fixedly installed field-effect tube 11, and 11 bottom of field-effect tube is fixedly installed magnet 8, the magnetic
