Abstract
The utility model relates to a throat control earphone, which comprises a neck stand, an earphone and a plug. A microphone and an amplifying circuit are fixed on the neck stand, wherein, the microphone is capable of converting sound vibration signals generated by laryngeal cavities of human bodies to electric signals. The output of the electrical signals of the microphone is connected with the input of the amplifying circuit through coupling capacitance. The output of the amplifying circuit is connected with the plug. The utility model is a throat control earphone which not only can effectively isolate various ambient noises and provide fair talking, but also can be dialed accurately with simple structure.
Description
The utility model relates to a kind of earphone, especially a kind of Throat control earphone, and it is to utilize the vibration of cavum laryngis to transmit sound, can be used as the earphone of mobile phone or fixed line phone.
Current society, mobile phone plays very important effect, also is an indispensable part during people live.Under the inconvenient environment of much making a phone call, as: drive, by bike, occasions such as the doctor wears masks, construction, people use miaow head or miaow head earphone to make a phone call usually.But use miaow head earphone to make a phone call to exist following deficiency: 1, noise is heavy, and all sound the other side can both hear at one's side, can not use substantially under heavy noisy environment; 2, use acoustic control dialing accuracy rate extremely low.
The purpose of this utility model be intended to overcome above-mentioned prior art deficiency, propose a kind ofly can effectively to isolate various environmental noises, conversation is clear, accurately dialing again, and Throat control earphone simple in structure.
Realize the technical scheme of above-mentioned purpose: a kind of Throat control earphone, comprise neck frame, earphone and plug, it is characterized in that: on the neck frame, be fixed with transmitter and amplifying circuit that the sound vibration signal that the human body cavum laryngis is sent is converted to the signal of telecommunication, the signal of telecommunication of transmitter is output as the input of amplifying circuit, the output plug of amplifying circuit.
Transmitter is the beep sheet.
The output of transmitter connects the input of amplifying circuit through coupling capacitance.
Amplifying circuit is a transistor amplifier, and the signal of telecommunication of transmitter connects the base stage of triode after coupling capacitance, and the collector electrode of triode, the output of the voltage between the emitter also are connected to filter capacitor.
Adopt technique scheme, because the utility model utilizes the pronunciation of human body cavum laryngis to vibrate dexterously and transmits sound, realize acoustic control dialing and conversation, its advanced technique effect is: 1, isolated the influence of various environmental noises to dialing and conversation fully; 2, during logical language, people do not need to speak up, and only need whisper, even only by the vibration of cavum laryngis, just can be under various environment speak in a soft, gentle voice, clearly converse; 3, whisper, realize good confidentiality; Show through actual tests that 4, according to the Throat control earphone that the utility model is made, sound resolution improves greatly, the resolution that can will have miaow head earphone now is brought up to more than 98% from 60%; 5, the utility model is simple in structure, and cost of manufacture is low, and is economical and practical.
Below in conjunction with accompanying drawing, its structure is described in detail in detail by embodiment:
Fig. 1 is a kind of circuit structure of the present utility model.
Fig. 2 is a shape assumption diagram of the present utility model.
Embodiment: see figures.1.and.2, a kind of Throat control earphone, comprise ring-like neck frame 1, plug 2, earphone 3, transmitter 4 (in Fig. 2, representing) and amplifying circuit 5 with symbol M, transmitter M and amplifying circuit 5 that the sound vibration signal that the human body cavum laryngis is sent is converted to the signal of telecommunication are fixed on the ring-like neck frame 1, transmitter M is peak a toot sheet, amplifying circuit 5 is a transistor amplifier, transistor amplifier is made up of triode Q1, resistance R 1, R2, R3, R4, coupling capacitance C1 and filter capacitor C2, V among Fig. 2
DDBe the high impedance power supply.During use, with ring-like neck frame from after be placed on the neck, earphone is put into the earhole limit, the sound vibration signal that cavum laryngis sends converts the signal of telecommunication to by transmitter M, signal of telecommunication output connects the base stage of triode Q1 through coupling capacitance C1, voltage output after the collector electrode of triode Q1, emitter amplify is by earphone jack or fixed line phone socket on the plug 2 external mobile phones, can realize acoustic control dialing and conversation behind the noise isolation.
In the present embodiment, transmitter is the beep sheet, also can adopt other transmitter that vibration signal can be converted to the signal of telecommunication to replace.
Amplifying circuit also can adopt the amplifier of other type except adopting transistor amplifier.
