Abstract
The utility model provides a sound film. The sound film comprises a dome part and a suspension ring part around the dome part. The sound film is characterized in that the dome part is provided a plurality of normal patterns which are perpendicular to the periphery of the dome part and tangential patterns which are parallel to the periphery of the dome part, wherein the normal pattern and the tangential pattern intersect. With the design, normal and tangential strength are increased simultaneously. In high-frequency vibration, possible distortion of the dome is minimized as far as possible, thus a loudspeaker acquires great acoustic performance.
Description
[technical field]
The utility model relates to a kind of sound film, relates in particular to the sound film on the magnetic speaker.
[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.
Magnetic speaker is loud speaker a kind of of widespread usage; It comprises the vibrational system of magnetic circuit system vibration with driven by magnetic circuit system; Vibrational system generally includes the magnetic field effect of induction magnetic circuit system and receives the voice coil loudspeaker voice coil of its vibration and driven and the sound film of vibration sounding by voice coil loudspeaker voice coil; The sound film generally includes the ball top that is positioned at middle position, the connecting portion that centers on the ball top; The sound vibration of membrane is main with the vibration at ball top, and the Oscillation Amplitude of the relative connecting portion of amplitude at ball top is big, frequency is high, is the important component part that embodies the loud speaker acoustic efficiency.
In the product of correlation technique, the ball top of sound film is typically provided with decorative pattern, and decorative pattern is to be used at the sound film or the ball roof pressure goes out the striated indenture or convex epirelief strengthens rigidity; Make it the time be not easy torsional deformation in vibration, desirable state be ball when withstanding on vibration all positions can be a complete rigid body straight up and down; Do not cut apart vibration; But when dither, possibly also can there be torsional deformation in the ball top, can't obtain acoustical behavior preferably.
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 sound film that possesses better acoustical behavior.
The utility model is to realize through such technical scheme:
A kind of sound film, the ring portion that it is provided with the ball top and centers on the ball top, said ball top is provided with some normal direction decorative patterns vertical with ball top periphery, and the tangential decorative pattern parallel with ball top periphery, and said normal direction decorative pattern and said tangential decorative pattern intersect.
As a kind of improvement of the utility model, said tangential decorative pattern is one decorative pattern.
As a kind of improvement of the utility model, said tangential decorative pattern is an all over design.
The utlity model has following advantage: can gain in strength in normal direction and tangential simultaneously, when dither, reduce the torsional deformation that the ball top possibly exist as far as possible, obtain acoustical behavior preferably.
[description of drawings]
Fig. 1 is the constitutional diagram of the utility model sound film;
Fig. 2 is the exploded view of the utility model sound film;
Fig. 3 is the vertical view of the utility model sound film.
[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
Like Fig. 1, shown in Figure 2, the utility model sound film 1 comprises ball top 11 and centers on the ring portion 12 at above-mentioned ball top 11.
As shown in Figure 3, said ball top 11 is provided with some normal direction decorative patterns 111 and one continuous tangential decorative pattern 112.Said normal direction decorative pattern 111 is vertical with the periphery 113 at ball top 11, and said tangential decorative pattern 112 is parallel with the periphery 113 at ball top 11.Said normal direction decorative pattern 111 intersects with said tangential decorative pattern 112.
In other embodiments, said tangential decorative pattern also can be multiple tracks, and is continuous or discontinuous.
This design can be gained in strength in normal direction and tangential simultaneously, when dither, reduces the torsional deformation that the ball top possibly exist as far as possible, obtains acoustical behavior preferably.
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.
Claims (3)
