Technical field

The utility model relates to a kind of earphone muffle, especially a kind of one's voice in speech device of unofficial biography not can make the conversation of mobile phone or telephone set the time.Belong to Communication Equipment.

Background technology

Existing mobile phone and telephone set send words and answer all and finished by microphone and receiver, the time award sound signal that words send when conversation and be transformed into electric signal through phone by the microphone collection of microphone, send behind the electromagnetic wave signal, the words that the other side is transmitted are answered by receiver, because receiver is nearer apart from ear, sound is less, can not leak, awarding when words to award the words sound signal certain intensity is arranged catching to make in order to make, people on every side certainly will hear, very inconvenient in some specific occasions, people around may bothering on the one hand, the people that words should not be heard that awards that can make privacy on the other hand and maintain secrecy hears, also makes the other side not hear and award words because of receiving noise simultaneously in the big occasion of noise.

Summary of the invention

The purpose of this utility model is to provide a kind of the elimination when keeping mobile phone and telephone set normal talking to award the words servicing unit that sound leaks

The utility model adopts the method that earphone muffle is set on existing mobile phone and telephone set to realize.

Earphone muffle is made up of mouth piece, muffler, gosport and adapter.Mouth piece is by on mouth during conversation, sound signal when making mouth award words can not spread out of around mouth piece, only empty propagation in mouth piece, a sound signal part is delivered on the microphone of mobile phone or telephone set from gosport by adapter, pass in the air after the noise reduction of remainder process muffler, mouth piece and gosport all have acoustic material outward.Award the words sound signal and the sound signal of unofficial biography is cut to import in the air again enough for a short time, also can not make noise on every side import microphone into regard to having realized that bio-occlusion mobile phone or telephone set send like this.Earphone muffle is an auxiliary equipment, is just to insert when the needs noise reduction, and the time spent has not separated with mobile phone or telephone set as long as seam just separated with mobile phone or telephone set.

Because adopted above technical scheme, cellphone subscriber to use the utility model when conversation, conversation has sound can not heard by the third party, effectively prevented the people of conversation sound shadow around ringing, prevented that also caller's privacy and the words content of awarding of maintaining secrecy from being heard by the stranger.

Description of drawings

Fig. 1 is the earphone muffle schematic diagram.

Fig. 2 is the mouth piece schematic diagram in the earphone muffle.

Fig. 3 removes the schematic diagram of muffler for earphone muffle.

Number in the figure is followed successively by: mouth piece 1, muffler 2, gosport 3, adapter 4, sonic propagation mouth 5, gosport fixed mount 6.

Embodiment

Referring to Fig. 1,2, the design of mouth piece 1 can be with reference to the blow gun of spirometer, can realize sealing mouth around, the inside branch makes allowances for the motion of lip when speaking, making speak convenient.Mouth piece 1 can directly be made with having the sound insulation materials with function, and also available general material is made outer then Complex lid acoustic material, to seal when speaking around the mouth contact portion of more comfortable mouth piece and face and can use some soft materials in order to make, but can not influence soundproof effect.Muffler 2 is wanted close-coupled with mouth piece 1, unnecessary sound wave when speaking passes in the air after entering the muffler noise reduction by sonic propagation mouth 5 again, muffler can adopt various noise-reducing structures to the erasure effect of sound according to actual conditions, allows the sound wave of speaking effectively weaken the energy of sound wave by the back.Gosport 3 is the logical soft blank pipes in two, and sound wave can be propagated therein, and gosport 3 one ends can be connected according to actual conditions and also can be connected on the mouth piece on the muffler, and this end is the speak mouth that imports into of sound wave of phone collection, and the sound wave that choose imports the position into.What draw among the figure is that gosport 3 is connected the situation on the mouth piece, on mouth piece, establish gosport fixed mount 6, gosport 3 one ends are fixed on the gosport fixed mount 6, pipe stretches out from muffler, can stretch out from the bottom according to actual conditions, also can stretch out from the limit, acoustic material is arranged outward, the other end communicates with adapter 4.Adapter 4 is connected with gosport 3, the effect of adapter 4 is to allow acoustic duct that gosport 3 transmits go into the microphone of mobile phone or telephone set and do not leak, be gosport sound wave spread out of mouth, closely contact sound wave when the anchor ring in exit can make it with soft acoustic material to link with microphone and do not leak, adapter 4 can be established realization loose joints easily at any time such as clip, button, cover to the openning of the microphone of mobile phone or telephone set.Adapter 4 can be made tailored version and universal, and tailored version is for being used on special mobile phone and the telephone set, and adapter 4 adopts corresponding bridging mode according to the microphone position characteristics of special mobile phone and telephone set; Universal is to adopt general bridging mode at the common feature of all kinds of mobile phones and telephone set, it is universal etc. to be divided into mobile phones universal type and telephone set, and the wide in variety of mobile phone also can be designed all kinds of general adapter that is common to slip lid, straight plate, clamshell phone respectively at the characteristics of slip lid, straight plate, clamshell phone.
