Abstract

The present invention relates to a telephone microphone of a communication device telephone, particularly to an immunologic sterilizing telephone microphone which comprises a microphone shell, a sound conducting device and a receiver. The immunologic sterilizing telephone microphone is characterized in that the microphone shell is provided with two transmitting microphone assembly through holes; the sound conducting device, a transmitting microphone supporting frame and a volume compensation amplifier are fixed in the microphone shell; a transmitting microphone is fixed in the microphone shell through a clamping sleeve; a cavity type transmitting microphone structure can make various kinds of gaseous and liquid dirt which enters the telephone microphone along with acoustic waves discharged through the conical through holes to perform the functions of exhausting gases and eliminating humidity, and thus, the service life of elements in the transmitting microphone is extended. Besides, the transmitting microphone can be separated from the microphone shell and is especially sterilized.

Description

A kind of Antiepidemic sterilizing mouthpiece

The invention belongs to the mouthpiece part on the communication apparatus telephone set.

Existing mouthpiece mounts sterilized tablet for the propagation of anti-epidemic disease bacterium at the position of giving orders or instructions, can reduce germ like this propagates when making a phone call, but it is this by efficacy of a drug sterilization high volatility, can only keep certain hour and can't separate tide by hydrofuge, mouth is pressed close to the saliva of the position when speech ejection of telephone transmitter, assorted flavor, the gas dirt deposits in mouthpiece by sound transmission aperture, formed the germ reproduction source, so mount sterilization and germ reproduction problem that the sterilization tablet can't fundamentally solve mouthpiece, patent announcement number is a kind of for CN2232645A discloses to be connected microphone by mechanical inserted formula method, microphone the special use for the special messenger can be separated, sterilization problems can not be fundamentally solved like this.

The objective of the invention is in order further to solve the germ immunization issues of mouthpiece, and make the mouthpiece position of giving orders or instructions to carry out thorough disinfection.

Method for designing of the present invention is a kind of Antiepidemic sterilizing mouthpiece of design, and it comprises microphone housing, microphone, obedient device, line, it is characterized in that: have cavity type mouthpiece two assembling through holes up and down in the give orders or instructions upper and lower end face of position microphone housing of mouthpiece; Mouthpiece is and the separable cavity type mouthpiece of microphone housing, owing to the feature that the cavity type mouthpiece can be separated from the assembling through hole of microphone housing, so can sterilize specially; The upper and lower end face of cavity type mouthpiece is to make cross-ventilated through hole, the dirt of spurting into gas, liquid, the disease carrying germ of microphone with sound wave can be excreted out and hydrofuge is separated tide and prevented epidemic; Have hole on the perisporium of mouthpiece; Mouthpiece fixes by cutting ferrule and microphone housing; Cutting ferrule is the hollow garden cover that certain wall thickness is arranged; At microphone housing internal fixation mouthpiece bearing support and volume compensated amplifier are arranged; The transmission of mouthpiece volume is the transfer mode of Air Coupling.

Described cavity type mouthpiece, upper port has flange, and top cylinder portion is tapered, the sound hole of perisporium; Doffing portion is straight tubular, and there is the lamp socket type bayonet socket bottom, is with spring housing and cut spring on the cavity type mouthpiece.

Described hollow garden cover, there is the little garden of flange form platform in the outer garden at middle part on week; There is the card key of symmetry the side end face of hollow garden cover on the week of endoporus garden; There is equally distributed plane teeth in the garden of the other end of hollow garden cover on week, be with compression spring on the cutting ferrule.

Described volume is amplified compensator and is made up of compensation microphone, amplifier, microswitch, button cell, earphone; Volume is amplified between compensator and the mouthpiece primary circuit does not have line, does not therefore increase former electrical network load; Microswitch is fixed on the microphone enclosure can conveniently control volume.

The position is a kind of separable cavity type mouthpiece because the microphone of the present invention's design is given orders or instructions, this isolating construction has solved telephone transmitter thorough disinfection problem, and cavity type mouthpiece structure can with enter all gases of microphone with sound wave, the dirt of liquid excretes out by through hole, do not form the epidemic disease source on the surface and can not cause dirt and stop up alluvial, because air convection current and light radiation in the cavity type mouthpiece make mouthpiece be in the transom window that drying regime forms people's mouth, promptly play the epidemic prevention effect that hydrofuge is separated tide; Prolonged the useful life of element in the microphone again.For solving the volume loss problem of cavity type mouthpiece, on the perisporium of cavity type mouthpiece, have hole, volume is housed in the microphone housing amplifies compensator, it is little power consumption that volume is amplified compensator, make power supply by button cell, be that independent closed-system is noiseless to telephone set exchange, electrical network, do not increase the electrical network load.

Below in conjunction with example figure the present invention is described in further details.

Accompanying drawing 1 is not comprise the microphone structural representation of listening the microphone part.

Accompanying drawing 2 is cutting ferrule structural representations.

Accompanying drawing 3 is mouthpiece released state schematic diagrames.

In the accompanying drawing: 1, microphone housing, 2, the cavity type mouthpiece, 3, the mouthpiece bearing support, 4, cutting ferrule, 5, the little garden of the flange form of cutting ferrule platform, 6, spring housing, 7, cut spring, 8, compression spring, 9, sound hole, 10, the lamp socket type bayonet socket, 11, the card key, 12, microphone, 13, compensation microphone, 14, amplifier, 15, microswitch, 16, button cell, 17, earphone, 18, through hole, 19, go up pilot hole, 20, pilot hole down, 21, occluded air chamber V3.

As shown in Figure 1, when cavity type mouthpiece 2 was fixedly connected on the microphone housing 1, card key 11 was stuck in 10 li of the lamp socket type bayonet sockets of mouthpiece 2, and the elastic force effect of compression spring 8 is fixed on the microphone housing cutting ferrule 4.With mouthpiece sound hole 9 corresponding microphone 12 and the compensation microphones 13 of being fixed with, be fixed with earphone 17 with the microphone position adjacent, certain air gap V3 is arranged between microphone and the earphone.

If want mouthpiece is separated from the mouthpiece housing, give revolving force of cutting ferrule plane teeth port with hand, the card key of cutting ferrule is spun off from the lamp socket type bayonet socket, when the card key of cutting ferrule is separated from from the lamp socket type bayonet socket,, takes out the cavity type mouthpiece and can sterilize specially because the elastic force effect of cut spring 7 is ejected the cavity type mouthpiece from microphone housing assembling through hole.
