Abstract

The invention relates to a sound production method of an electronic frequency-dependent horn of a silicon mike sensor. At present, a microphone of an electronic horn sold on the market is an electret condenser microphone which is large in size, heavy in weight, low in mechanical vibration resistance capacity, non-resistant to high temperature and moist, and easy to rust, and affects performance of the horn. The electronic frequency-dependent horn of the silicon mike sensor comprises a horn membrane (4), wherein the horn membrane is connected with a silicon microphone sensor (5) through pressure signals generated by vibration, and the silicon microphone sensor is fed back to a 555 timer (1) through acoustoelectric conversion. The sound production method is used for the field of industrial horns.

Description

The electronics of silicon Mike transducer is with the vocal technique of frequency loudspeaker

Technical field:

The present invention relates to a kind of electronics of silicon Mike transducer with the vocal technique of frequency loudspeaker.

Background technology:

The microphone of the electronic horn of Xiao Shouing is electret capacitor microphone in the market, and this microphone volume is big, and quality is big, and anti-mechanical oscillation ability is low, and non-refractory and humidity, and corrosion easily influences the loudspeaker performance.

Summary of the invention:

The objective of the invention is provides the vocal technique of a kind of electronics of silicon Mike transducer with the frequency loudspeaker at above-mentioned shortcoming, in order to solve the above problems.

Above-mentioned purpose realizes by following technical scheme:

A kind of electronics of silicon Mike transducer is with the frequency loudspeaker, and its composition comprises: the loudspeaker diaphragm, and described loudspeaker diaphragm connects the silicon microphone transducer by the pressure signal that vibration produces, and described silicon microphone transducer connects 555 timers by the acoustic-electric conversion.

The electronics of described silicon Mike transducer is equipped with charge pump with the frequency loudspeaker on the described silicon microphone transducer, and described charge pump connects the vibrating membrane on the described silicon microphone transducer.

The electronics of described silicon Mike transducer is with the frequency loudspeaker, and described 555 timers comprise two comparators, and described two comparators all connect rest-set flip-flop, and described rest-set flip-flop connects discharge tube.

A kind of electronics of silicon Mike transducer is with the vocal technique of frequency loudspeaker, behind the air pressure signal that utilizes silicon microphone to gather the vibration of loudspeaker diaphragm as transducer and produce, conversion feeds back to the input of two comparators of 555 timers through acoustic-electric, thereby change two comparator output voltages, the state of control RS trigger and discharge tube, control frequency and the duty ratio of the output of 555 timers, to reach consistent with the natural frequency of diaphragm, produce the mechanical oscillation effect of optimum Match.

Beneficial effect:

1. when the silicon microphone transducer of the present invention's employing is connected work with charge pump, can produce the electric charge that continues at vibrating membrane, can between voice signal and power supply noise, form well and isolate; In case humidity reduces, the electric charge on the vibrating membrane can be charged again by charge pump, thereby the recovery rapidly from the environment of humidity of this class Mike wind energy, and the wet ability of moisture resistance is strong, is difficult for corrosion, has improved the performance of loudspeaker, has prolonged the useful life of loudspeaker.

When the silicon microphone transducer that the present invention adopts is connected work with loudspeaker, because vibrating membrane is very little, and is insensitive to vibrating, in the life cycle of microphone, can not produce the electric charge decline, can not produce the skew of sensitivity owing to the variation of supply power voltage, so anti-vibration ability of the present invention is strong.

The silicon microphone transducer that the present invention adopts with can be at a lot of extreme environmental conditions suction reliably workings after loudspeaker are connected, it does not need punching press just can withstand the pb-free solder reflux temperature, so high-temperature resistance of the present invention is strong.

Heavy Weight, anti-mechanical oscillation effect is not as good as MEMS Mike.

The silicon microphone volume that the present invention adopts is little, and quality is little, has alleviated the weight of whole loudspeaker, and it is more convenient that the present invention is installed, and it is little to occupy the space, operates more flexible.
