Description
Technical field
The utility model is related to electro-acoustic product technical fields, and in particular to a kind of earphone Microspeaker.
Background technology
With the continuous development of digital electric technology, such as MP3 (music player), mobile phone and PAD (tablet computer) tool
There is the portable electronic device type of playing audio signal more and more, using also more and more universal.Earphone can will be above-mentioned each
The sound that kind electronic equipment is sent out is transmitted directly to the ear of user, avoids shadow of the extraneous noisy environments to listening effect
Ring, provide good voice signal for user, while do not affect also surrounding other people, have just because of earphone
Above-mentioned advantage, earphone are our usually one of very high carry-on equipment of frequency of use, and a good earphone can not only allow you to enjoy
By high tone quality and more rich details is listened to, while also damage of the hearing of let us from those poor earphones.Influence earphone sound
Qualitative factor mainly has the quality that the quality of loudspeaker unit and wire rod, especially loudspeaker unit directly determines sound.
For the most common moving-coil earphone of people, influencing loudspeaker unit element qualitative factor has very much, and vibrating diaphragm is then
Can loudspeaker unit possess one of critical component of quality.So-called vibrating diaphragm is one in fact for the very sensitive member of changes of magnetic field
Part, when electric signal passes through coil, magnetic field generates variation, leads to vibrating diaphragm stress deformation.Quickly due to change in electric, it leads
Vibrating diaphragm vibration at high speed is caused, then air is passed to by vibration of membrane of shaking, to produce sound wave.In this process, vibrating diaphragm
Quality determines the total quality of earphone.
The type of vibrating diaphragm has very much, has papery vibrating diaphragm, wooden vibrating diaphragm, plastics vibrating diaphragm, metal vibration diaphragm etc., generally in earphone
In, the design requirement of vibrating diaphragm is that quality is lighter, rigidity is better preferably, and such vibrating diaphragm can completely turn the kinetic energy of coil
It is melted into sound.And for most of moving-coil earphone at present on the market, use is substantially plastics vibrating diaphragm, even that
The earphone of the thousands of members of a little prices is also often used plastics vibrating diaphragm.
Plastics vibrating diaphragm mentioned here be in fact all kinds of high-molecular compounds general designation (including：PET/PEN/PEI/PI/
LCP/PEEK/PC/PPS/PAR etc.), and when specific to each compound, physical characteristic is again different.They common
Point is that plasticity is high, and easy processing is at low cost, but rigidity is poor, if to obtain preferable rigidity, is needed to increase vibrating diaphragm thickness
Degree is cost.This kind of vibrating diaphragm it is big to be easy to cause distortion, it is difficult to really restore primary sound since its internal resistance is small, poor rigidity.But due at
This advantage, most of earphones on the market can all use plastics vibrating diaphragm.
The improvement of modern sound sources technique, especially CD, SACD, DVD-Audio etc., the improvement of power amplifier push simultaneously
Drive the improvement of loud speaker.Since the requirement to loudspeaker unit is more and more high, to which the requirement to vibrating diaphragm is more and more high, therefore just
Need constantly to research and develop new material, new technology goes to meet such demand, the technology of loud speaker is required and is wanted to vibrating diaphragm vibrating diaphragm
Ask relationship as shown in the table：
| Requirement to loud speaker | The condition that vibrating diaphragm is required |
| Higher sensitivity | Quality is small (density is small) |
| Low distortion, good linearity | High resiliency, high internal resistance Buddhist nun, axial symmetry, air-tightness |
| Broadband | Height is better than spring rate, geometry |
| Frequency response curve is uniform | Geometry is good, appropriate internal damping |
| Reliability | It is heat-resisting, moisture-proof, fire-retardant, waterproof, mould proof |
| Low price | Handling ease, convenient material drawing, caking property are good |
As can be seen from the above table, in diaphragm materials, process aspect, it is reasonable to require each individual event for some technologies
, but it is shifting, conflicting to execute.Such as：Quality is small to be difficult to rigidity greatly；Elasticity modulus it is high and simultaneously
Internal damping is just highly difficult greatly again.
