Abstract
The utility model discloses a vibration diaphragm which comprises the following components: a vibration diaphragm body which is made of a thinner diaphragm, and a vibration diaphragm bracket which is made of a thicker diaphragm. The vibration diaphragm body is adhibited on a front surface of the vibration diaphragm bracket. The front surface of the vibration diaphragm bracket is provided with a plurality of closed through holes. The vibration diaphragm body is exposed in the through hole. Thus the structure of the vibration diaphragm is reinforced. The phenomena such as dividing vibration and unstable vibration can be prevented in the vibration process. The effects of low vibration amplitude, high power and low FO can be obtained thereby improving the tone quality of a speaker.
Description
Technical field
The utility model relates to a kind of vibrating diaphragm.
Background technology
Existing vibrating diaphragm is an individual layer diaphragm project organization, but be accompanied by the trend of loud speaker miniaturization, loud speaker is done littler and littler, corresponding vibrating diaphragm is done thinner and thinner, and the thin more then amplitude of vibrating diaphragm is big more, but the vibrating diaphragm oscillation space is more and more littler, easily in the space, be rebuffed during the vibrating diaphragm vibration and form noise, and the thin more easy more steady phenomenon of vibration and vibration that occurs cutting apart of diaphragm causes that the speaker product amplitude is big, FO is lower, power is lower, noise is bigger, and occurs the audio distortions phenomenon easily.
Summary of the invention
The purpose of this utility model provides a kind of short arc, low FO, high-power vibrating diaphragm.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vibrating diaphragm, comprise by the vibrating diaphragm main body of making than diaphragm, by the vibrating diaphragm support of making than the thick film sheet, described vibrating diaphragm main body is sticked at the front or the back side of described vibrating diaphragm support, the setting that flushes of the edge of the edge of described vibrating diaphragm main body and described vibrating diaphragm support, the front of described vibrating diaphragm support has the perforation of a plurality of closures, and described vibrating diaphragm main body is exposed in the described perforation.
Preferably, described vibrating diaphragm main body is sticked at the front and back of described vibrating diaphragm support, the setting that flushes of the edge of the edge of described vibrating diaphragm main body and described vibrating diaphragm support.
Preferably, the perforation of described closure is arranged on the front center of vibrating diaphragm support, and the vibrating diaphragm main body that is sticked on the front of described vibrating diaphragm support is exposed in the described perforation.
Preferably, the perforation of described closure is arranged on the front edge place of vibrating diaphragm support, and the vibrating diaphragm main body that is sticked on the front of described vibrating diaphragm support is exposed in the described perforation.
Preferably, the perforation of described closure is arranged on the front center and the edge of vibrating diaphragm support, and the vibrating diaphragm main body that is sticked on the front of described vibrating diaphragm support is exposed in the described perforation.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: adopt fixedly vibrating diaphragm main body of vibrating diaphragm support, and on the vibrating diaphragm support, offer perforation, the vibrating diaphragm main body is sticked on the reinforcement back side, during vibration, because the vibrating diaphragm support is thicker, so amplitude is lower, the phenomenon of being rebuffed can not take place in oscillation space, simultaneously because the effect of support, vibrating diaphragm is not easy to cut apart vibration and the not steady phenomenon of vibration, thus can help loud speaker to realize short arc, low FO, high power, and then have better tone quality.

Accompanying drawing 2 is the schematic top plan view of the utility model non-circular structure.
Accompanying drawing 4 is the schematic top plan view of the utility model circular configuration.
Embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Referring to shown in Figure 1, look schematic diagram with the master a kind of non-circular structure of the present utility model has been shown, be sticked by vibrating diaphragm support 1 front of making by the vibrating diaphragm main body of making than diaphragm 2 than the thick film sheet, vibrating diaphragm main body 2 also can be sticked at the back side of vibrating diaphragm support 1, the setting that flushes of the vibrating diaphragm main body 2 that also can all be sticked, the edge of the edge of vibrating diaphragm main body 2 and vibrating diaphragm support 1 at the front and back of vibrating diaphragm support 1.
Referring to shown in Figure 2, show a kind of non-circular structure of the present utility model with schematic top plan view, perforation 3 is set in the center of vibrating diaphragm support 1, edge at vibrating diaphragm support 1 is provided with perforation 4,5, perforation 4,5 can be symmetrical arranged or asymmetric setting, vibrating diaphragm main body 2 is exposed to perforation 3,4, in 5, vibrating diaphragm is installed in voice coil loudspeaker voice coil inside, and during work, initial vibration is to drive vibrating diaphragm support 1 by voice coil loudspeaker voice coil, because vibrating diaphragm support 1 is made by thicker diaphragm, thicker on the structure, so amplitude can be smaller, power ratio is higher, when vibrating diaphragm vibrates to a certain degree, because of being exposed to perforation 3,4, vibrating diaphragm main body 2 in 5 is made by thin diaphragm, and thinner on the structure, compliance is relatively good during vibration, so can reduce FO again, realize the low FO of Microspeaker, high-power effect.
Referring to shown in Figure 3, look schematic diagram with the master a kind of circular configuration of the present utility model has been shown, the setting that flushes at the edge of the edge of the vibrating diaphragm main body 9 in vibrating diaphragm support 8 fronts and vibrating diaphragm support 8 is sticked, vibrating diaphragm main body 9 also can be sticked at the back side of vibrating diaphragm support 8, vibrating diaphragm main body 9 also can all be sticked at the front and back of vibrating diaphragm support 8, edge at vibrating diaphragm support 8 is provided with perforation 6,7, and perforation 6,7 can be symmetrical arranged or asymmetric setting.
Referring to shown in Figure 4, show a kind of circular configuration of the present utility model with schematic top plan view, vibrating diaphragm main body 9 is sticked on vibrating diaphragm support 8 front face surface, vibrating diaphragm main body 9 is exposed to perforation 6, in 7, because vibrating diaphragm support 8 is made up of thicker diaphragm, so behind vibrating diaphragm of the present utility model after 9 composite moldings of vibrating diaphragm main body, the structure of vibrating diaphragm has obtained reinforcement, in vibration processes, can prevent and cut apart vibration, vibrate phenomenons such as not steady, thereby guaranteed the low THD of product, bad phenomenon such as Dip can not appear in curve, can accomplish short arc, high power, the effect of low FO, thus make the tonequality of loud speaker better.
