Abstract
The utility model provides a sound film, which comprises a body part arranged at the center and a silicone rubber folding ring surrounding the body part. The outer side of the silicone rubber folding ring is provided with a plastic ring connected with the silicone rubber folding ring. The plastic ring of the product can be directly combined with a basin-shaped frame or a mesh cover, the deformation of the sound film can be avoided, the consistency of vibration of the sound film can be enhanced, and the improvement of the acoustic performance of the sound film can be facilitated.
Description
[technical field]
The utility model relates to a kind of sound film, relates in particular to the sound film on the microphone device.
[background technology]
Fast development along with electronic information technology; Increasing microphone device is applied on each electronic product; Especially widely the mobile communication equipment used of people, people not only are concerned about its microminiaturization, multi-functional, more require its sound effect high-quality, undistorted.And the sound film is as the core component of microphone device, and the quality of its design directly affects the performance of acoustical device.
In the product of correlation technique, the sound film is provided with main part that is positioned at central authorities and the silicon rubber ring that centers on main part, usually; The silicon rubber ring directly directly combines with the basin frame or the guard of accommodating the sound film, but because the silicon rubber ring is softer, easy deformation in the assembling process; And need do plasma treatment on the surface; So, not only can influence the profile of sound film, destroy its vibration consistency; Also can increase technology, waste operation, make frock become complicated.
Therefore, be necessary to provide a kind of new technical scheme to improve the problems referred to above.
[utility model content]
The technical problem that the utility model need solve is to provide a kind of function admirable, on-deformable sound film in assembling process.
The utility model is to realize through such technical scheme:
A kind of sound film, it is provided with the main part that is positioned at central authorities, the silicon rubber ring that centers on main part, and wherein, the said silicon rubber ring outside also is provided with connected plastic hoop.
As a kind of improvement of the utility model, said main part is a silicone rubber membrane.
As a kind of improvement of the utility model, said main part is tabular.
As a kind of improvement of the utility model, the surface of said plastic hoop and the surface of main part parallel.
As a kind of improvement of the utility model, the section of said silicon rubber ring is arch.
The utlity model has following advantage: the silicon rubber ring outside of sound film is provided with connected plastic hoop; This plastic hoop can strengthen the hardness of sound film periphery; Thereby make things convenient for combining of sound film and basin frame or guard; Yielding phenomenon when avoiding in the past that the silicon rubber ring directly is connected with outside basin frame or guard in the technology, and then the consistency vibrated of enhancing sound film are beneficial to the raising of its acoustical behavior.
[description of drawings]
Fig. 1 is the sketch map of the utility model sound film.
[embodiment]
The sound film of the utility model is used for microphone devices such as loud speaker, promotes ambient air through vibration, and then sounds.
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
As shown in Figure 1; Sound film 10 for the utility model; The plastic hoop 13 that sound film 10 is provided with the main part 11 that is positioned at central authorities, the silicon rubber ring 12 that centers on main part 11 and centers on silicon rubber ring 12, this plastic hoop 13 links to each other around the outside of silicon rubber ring 12 and with silicon rubber ring 12.Plastic hoop 13 promptly is positioned at the outermost of sound film 10, is used for combining with the outside basin frame or the guard of accommodating sound film 10, because its good hardness; Can combine with outside basin frame or guard well; Overcome in the prior art,, can produce the phenomenon of sound film 10 distortion when directly combining with outside basin frame or guard because silicon rubber ring 12 is too soft; Cause 10 vibrations of sound film inconsistent, and then can influence the acoustic characteristic of sound film.
In the present embodiment, main part 11 is a silicone rubber membrane, can certainly be resin molding or plastic film also or metal film; Preferably, main part 11 is tabular.The section of silicon rubber ring 12 is arch.The surface of plastic hoop 13 is surperficial parallel with main part 11,
Above-described only is the execution mode of the utility model; Should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; Can also make improvement, but these all belong to the protection range of the utility model.
