Abstract
The utility model relates to the pulse microphone earphone of a mobile telephone. A body connected with a fixing device is provided with vibration suppression rubber materials. The center of the top part of the vibration suppression rubber materials is provided with a groove, an outer side is provided with a flange, and a bottom part is provided with a plurality of convex posts. The inner side of the groove is provided with a pulse microphone, and the top part of the vibration suppression is orderly provided with a ventilation sponge, a double-surface rubber sheet and an upper cover provided with a vibrated film sheet. The upper cover is combined with the body, and the pulse microphone and the earphone are connected with the telephone respectively through a signal line and a plug. A detecting surface is completely stuck to the throat positions of users by the fixing device, and the vibration of other illegal sound sources is effectively prevented. Therefore, the communication effects of clear sound quality and no noise interference are achieved. The utility model is especially suitable for the mobile phones.
Description
The utility model is a kind of pulsed microphone earphone that is applicable to mobile phone.
Microphone commonly used generally is the air vibration formula, its detecting principle is to borrow the vibration of air pressure to change the detecting diaphragm vibration that promotes in the microphone, pressure size and frequency speed along with air vibration, produce the synchronous variation of diaphragm position, convert electric variation again to, produce signal, use this air vibration formula microphone, can receive in the space other source of sound simultaneously.Make and produce noise in the communication, in more noisy environment, influence communication effect, be not suitable for mobile phone.
The inventor is at above-mentioned defective of the prior art, studies for a long period of time and tests, and creates the technical solution of the utility model.
The purpose of this utility model is to provide a kind of pulsed microphone earphone that is applicable to mobile phone, reaches the communication effect of sound clarity, the interference of no noise.
The purpose of this utility model is achieved in that a kind of pulsed microphone earphone of mobile phone, it is characterized in that: be provided with the glue material that shakes but be connected with in the body of fixture, but should shake the center of top of glue material be provided with that groove, the outside are provided with flange, the bottom is provided with most projections, this groove inboard is provided with the pulsed microphone, but be provided with ventilative sponge, double coated film at the top of this glue material that shakes in regular turn and have by the loam cake of vibrating diaphragm sheet, this loam cake and bulk junction integrator, this pulsed microphone is connected with telephone set by signal line and plug respectively with earphone.
But described body, loam cake and the glue material that shakes can be integrated formed structure, and this is an individual member by the vibrating diaphragm sheet, and be affixed with this body by gummed or ultrasonic waves fusion.
Major advantage of the present utility model is: communication is clear, and no noise disturbs.
Below in conjunction with preferred embodiment and accompanying drawing the utility model is further specified:
Fig. 1 is a stereo appearance figure of the present utility model;
Fig. 2 is a microphone section plan of the present utility model;
Fig. 3 is an audio frequency detecting structure sketch of the present utility model;
Fig. 4 is a user mode schematic diagram of the present utility model;
Consult Fig. 1, Fig. 2, structure of the present utility model comprises that body 10 is connected with fixture 11, but be provided with the glue material 12 that shakes in the inside of body 10, but should shake glue material 12 center of top be provided with that groove 13, the outside are provided with flange 14, the bottom is provided with most projections 15, be provided with pulsed microphone 16 in groove 13 inboards, but be provided with ventilative sponge 17, double coated film 18 and loam cake 19 in regular turn at the top of the glue material 12 that shakes, the capping of loam cake 19 be very thin thickness by vibrating diaphragm sheet 20, loam cake 19 is combined into one with body 10.The structure but certain body 10, loam cake 19 and the glue material 12 that shakes can be formed in one is an individual member by vibrating diaphragm sheet 20, and is affixed with body 10 by gummed mode or ultrasonic waves fusion.
Pulsed microphone 16 is connected with plug 22 with 24 by signal line 21 respectively with earphone 23, plug 22 can directly be plugged in the socket 34 of mobile phone 31, also can be plugged in earlier on the mobile phone 31 by adapter 33, plug 22 is plugged in the socket 32 of adapter 33 again.
Consult Fig. 3, audio frequency detecting structural feature of the present utility model is for being not easy by the vibrative material-structure of air vibration energy by vibrating diaphragm sheet 20 (being the end face of loam cake 19), but can be produced vibration by the liquid vibration energy of human throat vocal cords, the material-structure that satisfies this requirement comprises the elastic construction material of rubber-like.By the surface of vibrating diaphragm sheet 20 is detecting face 25, when detecting face 25 is responded to enough liquid vibration energy, will be changed on it by vibrating diaphragm sheet 20, upper/lower positions, thereby change the air pressure in pressure oscillation space 26, and by pushing of air molecule the detecting diaphragm 27 of driving pulse formula microphone 16, the position of detecting diaphragm 27 is done, the following variation, the change energy converter 28 that is positioned at its below becomes electrical signal with the power conversion of its change in location, this electrical signal is along with being done synchronous change by the amplitude variations of vibrating diaphragm sheet 20, but the glue material 12 that shakes is used as the vibration suppression of non-detecting face, makes pressure change space 26 and keeps pressure stable.
The junction of body 10 and loam cake 19 is used waterproof sealing 29 sealed engagement always, makes it have preferable water proofing property, constitutes firmly tight shell.
Fixture 11 must be selected the elastic structural material around property for use, is made generally in the geometrical clamp shape of C type, also can make to be suitable for easily detaining other shapes of restrainting in user's neck.
But the glue material 12 that shakes is colloid, elasticity, air-locked structural material, the normal rubber-like structure material that uses, it act as the change space 26 that keep-ups pressure and is not subjected to the ambient pressure energy affect, and the shell that minimizing is made up of body 10 and loam cake 19 conducts the inertia kinetic energy of coming in and reaches in the pulsed microphone 16.
By the solid-state colloidality structure material of vibrating diaphragm sheet 20 use suitable thickness, its thickness just can be vibrated by the liquid vibrational energy of throat portion, can prevent that again the more weak gaseous state vibration of energy from entering in the pressure oscillation space 26.
It is but that the bonding and air pressure of the double coated film 18 of flange 14 and its top by the glue material 12 that shakes is isolated sealing 30 and realized that the pressure in the pressure oscillation space 26 keep stable.Flange 14 is for having colloid, elasticity and air-locked characteristic member.
Consult Fig. 4, using method of the present utility model, earphone 23 is placed user's ear, utilize the fixture 11 of C type will detect the throat position that side 25 is attached at the user comprehensively, its sound generation source is the liquid vibration of throat, and 25 detectings of detecting face attach the one side of throat, can prevent effectively that the vibrational energy of other non-sound generation source from entering, reaching sound clarity does not have the communication effect that noise disturbs, and is specially adapted to mobile phone and uses at any time.
