Description

Eardrum and its loudspeaker

Technical field

The utility model refers to a kind of eardrum for loudspeaker, particularly relates to a kind of eardrum for having silicone rubber membrane valve.

Background technology

With the influence that modern life pressure improves and step is accelerated, music has turned into tight to adjust in people's life Open, the dull indispensable pith of life, so the loudspeaker of general consumer products is (such as：Loudspeaker, earphone etc.) institute The tonequality of music is shown, consumer can be influenceed when listening to music to the usage experience of loudspeaker.More with people's life water The raising of gentle spiritual pursuit, requirement of the consumer to tonequality is also more and more higher, therefore raising for general consumer products The requirement of sound device is paid attention to increasingly, thus improve tonequality and improve consumer usage experience, be a continual job and appoint Business.

In general, the loudspeaker of known techniques, shake its eardrum when passing through speaker operation, allow sound to pass through eardrum Propagated to outside loudspeaker, thus user can receive the sound.Furthermore the patent of invention of the U.S. the 6th, 415,037 more proposes one Kind horn structure, the U.S. patent Nos are mainly the framework for proposing a loudspeaker, and an eardrum, the framework are set along the framework periphery A resonant cavity is formed between the eardrum, the inner central of the framework is simultaneously provided with a coil, in this way, when the coil is done, Magnetic line of force change will be produced in resonant cavity center, and make to correspond on the eardrum magnetic set by the middle position of the coil Part, because effect, up-down vibration are denounceed in the suction that the change of the isodynamic line is formed, and then make the eardrum produce vibration and send sound Sound.Therefore, eardrum is an indispensable part for loudspeaker, and is enough to influence use body of the consumer to loudspeaker Test.

However, the eardrum of known techniques still suffers from many missings, for example, known eardrum includes a circular plastics material The film valve of matter and the circular membrane of a papery, the material that film valve uses is foam sponge, cloth, silica gel, rubber, plastics or metal etc. One of them, film valve is in hollow ring-shaped, and vibrating diaphragm is by manually fastening with glue in the middle vacancy of film valve and by outstanding edge Centre closing, only, during using being manually pasted on vibrating diaphragm on film valve with glue, easily there is paste position skew, make vibrating diaphragm and It the center of circle decentraction of film valve, can so increase the distortion level of loudspeaker, influence the quality of loudspeaker, the film valve and surrounding air are total to Vibration frequency people having the same aspiration and interest sex expression is poor, causes loudspeaker to show easy distortion in all-bottom sound resonant matter, can not provide user and listen to well Bass tonequality, aforementioned films valve simultaneously can not have favorable elasticity, ductility and tensile strength simultaneously, when loudspeaker start, enter And make resonant frequency caused by the film valve of the eardrum poor, make the sound transmission wide area of the loudspeaker poor.Met with for above-mentioned The problem of the problem of running into, industry can not provide effective settling mode, and actually current industry urgently overcomes.
