Abstract
The utility model relates to the field of vibration films of electro-acoustic energy converting devices, in particular to a ball top vibration film with an improved vibration film structure. A pleat ring portion of pleat veins of the ball top vibration film is formed by a first circular arc surface, a ring-plate pleat plane and a second circular arc surface, wherein the first circular arc surface is connected to the top portion of a ball, the ring-plate pleat plane is connected with the first circular arc surface,, and the second circular arc surface is connected between the pleat plane and a fixed portion. Accordingly, the structure of the vibration film is improved under the condition of not adding the height of the vibration film, the performance of a vibration area is improved, and the ring pleating strength of the vibration film is enhanced to reduce the influence of distortion.
Description
[technical field]
The utility model relates to the vibrating diaphragm field of electroacoustic energy switching device, specifically refers to a kind of ball top vibrating diaphragm of diaphragm structure improvement.
[background technology]
Along with improving constantly of the market demand, electronic device such as mobile phone etc. develops to the slimming direction gradually, and requires its sound quality to become better and better, and this just requires the acoustical device in the mobile phone to develop towards direction miniature, slim, high tone quality.Vibrating diaphragm is the core component of acoustical device such as loud speaker, and the requirement of its acoustical behavior is also just improved thereupon.
In relevant acoustical device the structure of vibrating diaphragm 100` as shown in Figure 1, it is by hemispheric ball top 10`, constitute around the pleat ring portion 20` of ball top 10` and the fixed part 30` that is connected with acoustical device basin frame (not shown), pleat ring portion 20` is provided with pleat line 21`; Usually pleat ring portion 20` has certain circular arc radian in the form of a ring, and pleat line 21` is positioned on the arc surface.Vibrating diaphragm 100` with this structure is in working order the time, owing to be subjected to the restriction of assembly space, making former pleat ring portion 20` with certain altitude increase height is difficult to the problem of improving the distortion of vibrating diaphragm 100` sounding, this must can influence vibrating diaphragm 100` distortion in various degree on the contrary with reducing the oscillation space of vibrating diaphragm 100`.
[utility model content]
The utility model is subjected to the restriction of assembly space at solving vibrating diaphragm in the acoustical device, causes the problem of vibrating diaphragm distortion, and a kind of ball top vibrating diaphragm is provided.
A kind of ball top vibrating diaphragm, comprise the ball top that is positioned at the centre position, the fixed part that centers on and connect the pleat ring portion at ball top and be connected location vibrating diaphragm integral body with the pleat ring portion, the pleat ring portion is provided with the pleat line, and wherein said pleat ring portion comprises first arc surface that connects the ball top, the ring plate shape pleat plane that connects first arc surface and second arc surface between junctional fold plane and the fixed part.
Preferably, the protrusion direction of described pleat anchor ring is opposite with the protrusion direction at ball top.
The utility model ball top vibrating diaphragm, the pleat ring portion at its pleat line place is to be made of first arc surface that connects the ball top, the ring plate shape pleat plane that connects first arc surface and second arc surface between junctional fold plane and the fixed part, under the situation that does not increase the vibrating diaphragm height, improve the structure of vibrating diaphragm like this, improve the performance of vibration area, strengthen the ring intensity of vibrating diaphragm, to reduce the influence of distortion.
[description of drawings]
Fig. 1 is the diaphragm structure schematic diagram that prior art discloses;
Fig. 2 is a schematic perspective view of the present utility model;
Fig. 3 is a side schematic view of the present utility model;
Fig. 4 is a floor map of the present utility model.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
Shown in Fig. 2,4, structural representation for the utility model ball top vibrating diaphragm 100, it comprises the ball top 10 that is positioned at the centre position, the fixed part 30 that centers on and connect the pleat ring portion 20 at ball top 10 and be connected location vibrating diaphragm integral body with pleat ring portion 20, and fixed part 30 is fixed on the basin frame of microphone device by glue hot pressing; Pleat ring portion 20 is provided with the pleat line 21 that improves performance, wherein said pleat ring portion 20 comprises first arc surface 201 that connects ball top 10, the ring plate shape pleat plane 202 that connects first arc surface 201 and second arc surface 203 between junctional fold plane 202 and the fixed part 30, the pleat ring portion 20 at pleat line 21 places will be the structure of a planar projection like this, the height of right single protuberance is consistent with the height of conventional ring, and this is just avoided taking up room.Described first arc surface 201 and second arc surface can be adjusted the circular arc R angle according to overall space size, for the acoustical generator of different model and size provides level of freedom, also help strengthening the intensity of whole pleat ring portion 20, reduce distortion.
In addition, as shown in Figure 3, the protrusion direction of described pleat anchor ring 20 is opposite with the protrusion direction at ball top 10, also is convenient to the making of pleat ring portion 20, improves intensity and Oscillation Amplitude, improves distortion.
Above-described only is execution mode of the present 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 protection range of the present utility model.
Claims (2)
1. ball top vibrating diaphragm, comprise the ball top that is positioned at the centre position, the fixed part that centers on and connect the pleat ring portion at ball top and be connected location vibrating diaphragm integral body with the pleat ring portion, the pleat ring portion is provided with the pleat line, it is characterized in that: described pleat ring portion comprises first arc surface that connects the ball top, the ring plate shape pleat plane that connects first arc surface and second arc surface between junctional fold plane and the fixed part.
