Abstract
The utility model relates to a micro membrane loudspeaker, belongs to the field of electro-acoustic communications technique, comprising a vibration membrane, a voice coil connected on bottom terminal of the vibration membrane, and assembled into the interval between a block and a rear cover, a magnetic with one side attached to the block, and the other side attached to the bottom of the rear cover, and a bottom plate mounted on the rear cover. The loudspeaker is characterized in that 11 discharge holes disposed on the rear cover, with 10 thereof having sound mixing paper joint thereon, so that the micro loudspeaker has gentle bass, mellow mediant and sonorous treble, avoids noise and shock sound. The product has a relatively low low-frequency resonant frequency, with F0 of 200Hz plus or minus 20 percent, is not broken in 96H white noise load test, can bear 18 times of drop test of 1.52 meters. The product has a wide application range, a long life, and is valuable to popularize.
Description
Technical field
The utility model relates to a kind of loud speaker, relates in particular to a kind of miniature thin-film loud speaker, belongs to technical field of telecommunications.
Background technology
In the market generally use be installed on loud speaker on the portable equipment, especially the film Microspeaker used of the external earphone of mobile phone, always more or less must there be following defective in its sound that gives off: promptly partly tend to bright inadequately at high pitch, also can allow the people feel that bass is not enough at bass part, or too dull, the overall sound quality deviation that makes the earphone generation.High and low sound aspect is all solved, the designer often adopts more and more thinner film to make vibrating diaphragm, when vibrating diaphragm is 6 μ, in use, in case situation appears falling in portable equipment, will cause the wrinkle of the noiseless or vibrating diaphragm of loud speaker, the vibrating diaphragm wrinkle cause and husky sound occurs, have a strong impact on useful life, be unfavorable for that the use of 6 μ film Microspeakers is promoted.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of miniature thin-film loud speaker is provided.
The purpose of this utility model realizes by following technical solution:
The miniature thin-film loud speaker, include copper band vibrating diaphragm, washer, bonnet, magnet, voice coil loudspeaker voice coil, base plate, adjustable sound paper composition, the vibrating diaphragm lower end is connected with voice coil loudspeaker voice coil, voice coil loudspeaker voice coil is packed in washer and the bonnet gap, the bonding washer of magnet one side, another side is bonded in the bottom of back cover cavity, and the bonnet bottom outer surface adds base plate, wherein: on described bonnet, offer 11 release aperture, have on 10 release aperture to be fitted with adjustable sound paper.
The purpose of this utility model also can further realize by following technical measures:
Above-mentioned miniature thin-film loud speaker, wherein, described release aperture is equally spaced circumferential arrangement.
Further, above-mentioned miniature thin-film loud speaker, wherein, described film thickness is 6 μ.
Again further, above-mentioned miniature thin-film loud speaker wherein, is distributed with 50 decorative pattern muscle at least on the described vibrating diaphragm, and the decorative pattern muscle is clockwise or counterclockwise uniform arrangement.
Advantage of the present utility model is: adopt after this structure, can rationally arrange the quantity and the distribution of release aperture, and release aperture has been carried out suitable covering, made the tonequality of Microspeaker: bass is powerful, middle pitch is mellow and full, high pitch is plentiful, tone color is fine and smooth, avoids occurring noise and sonic boom.Moreover the copper band vibrating diaphragm of 6 μ has the decorative pattern muscle, can strengthen anti-wrinkle, anti-dropping capability.This product has lower low-frequency resonant frequency, and F0 is 200Hz ± 20%, and white noise load test 96H does not damage, and bears 1.52 meters high 18 fall-down tests and does not damage, and product applied range, long service life are worth of widely use.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Embodiment
As Fig. 1～miniature thin-film loud speaker shown in Figure 3, include vibrating diaphragm 1, washer 2, bonnet 3, magnet 4, voice coil loudspeaker voice coil 7, base plate 5, adjustable sound paper 6 compositions, vibrating diaphragm 1 lower end is connected with voice coil loudspeaker voice coil 7, voice coil loudspeaker voice coil 7 is packed in the gap of washer 2 and bonnet 3, the bonding washer 2 of magnet 4 one sides, another side is bonded in the bottom of back cover cavity, and bonnet 3 adds base plate 5, its special feature is: offer 11 release aperture 8 on described bonnet 3, and be fitted with adjustable sound paper 6 at least 10 release aperture 8.Simultaneously, with regard to the utility model one preferred implementation, described release aperture 8 is equally spaced circumferential arrangement.The whole mellow and full degree that can further help tonequality thus.Moreover described vibrating diaphragm 1 thickness is 6 μ.At least be distributed with 50 decorative pattern muscle on it, the decorative pattern muscle serves as a contrast simultaneously with copper band and supports by clockwise or uniform regularly arrangement counterclockwise, can play good anti-wrinkle effect, has also guaranteed the anti-drop ability of vibrating diaphragm self simultaneously.
In conjunction with actual manufacturing process of the present utility model and result of use, cooperate various environment for use in order to make the miniature thin-film loud speaker, further guarantee its tonequality, the release aperture 8 that is not fitted with adjustable sound paper 6 can dispose according to actual needs.Specifically, as shown in Figure 3: can select totally enclosed ring-type adjustable sound paper 6 in advance for use, the local cutting that need not to cover in correspondence is left a blank then, the ring-type adjustable sound paper 6 after the cutting is fitted on the release aperture 8 to get final product at last.And bonnet 3 can adopt progressive die manufacturing, and its whole precision and concentricity are improved, and can guarantee that like this structure of whole film Microspeaker is rigorous.
Through contrast experiment's discovery repeatedly, the low-frequency resonant frequency of this miniature thin-film loud speaker is 200Hz ± 20%.Simultaneously, the sensitivity at the 1KHZ place is 118dB ± 3dB/1mW.Reached bass soft powerful, middle pitch is mellow and full, high pitch bright plentiful, tone color is fine and smooth.Moreover, falling 18 times from 1.52 meters eminences and do not damage, white noise load test 96H does not damage, and uses reliable.
By above-mentioned text description also in conjunction with the accompanying drawings as can be seen, after adopting the miniature thin-film loud speaker of this structure, can rationalize quantity and the distribution that distributes release aperture 8, and release aperture 8 has been carried out suitable covering, make the Microspeaker pronunciation: bass is soft, middle pitch is mellow and full, high pitch is bright, avoids it the phenomenon of noise and sonic boom to occur.Moreover, have 6 μ copper band vibrating diaphragms of decorative pattern muscle by employing, range of application and the useful life that can improve the vibrating diaphragm Microspeaker, be worth promoting the use of in the art.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
