Abstract
The invention discloses a vibrating diaphragm for an electroacoustic transducer. The vibrating diaphragm is integrally made of metal. The vibrating diaphragm comprises a vibrating wing and a support frame. Both the vibrating wing and the support frame are elongated in shape. One end of the vibrating wing is connected with the inner side of the support frame; the other end of the vibrating wing can vibrate up and down within the support frame and is connected with the support frame through a cantilever beam or a cross beam. The support frame and the cantilever beam or the cross beam are both made of metal, and the relative position of the vibrating wing can be well maintained. Vibration stiffness of the vibrating diaphragm is stable and controllable; fatigue resistance of the vibrating diaphragm is high. The vibrating diaphragm can be made in a strip by a continuous metal punching process, so that production of the vibrating diaphragm can be automated, cost of the vibrating diaphragm is greatly reduced, and yield is increased.
Description
Technical field
The present invention relates to electroacoustic transducer structure, relate more specifically to a kind of electroacoustic transducer diaphragm sheet.
Background technology
Electroacoustic transducer diaphragm sheet generally comprises support frame and flutter, described flutter is fixed on support frame, the support frame of existing vibrating diaphragm is generally made by stainless steel, flutter part is generally made by aluminium, two-part combined process precision prescribed is high, yields is lower, and cannot realize automation.In the later stage, need spraying binder to promote and film adhesion, the hinge of existing vibrating diaphragm is the sandwich structure of " metal+film+metal ", and vibrating diaphragm stiffness is uncontrollable, greatly affects receiver quality.Therefore, be necessary existing electroacoustic transducer diaphragm sheet to improve, avoid above-mentioned defect.
Summary of the invention
The present invention provides a kind of by the integrated vibrating diaphragm of metal in order to solve deficiency of the prior art, is convenient to automated production, and stability is high, cost is low, and vibrating diaphragm stiffness is controlled.During production, can adopt automatic forming mode, once hot-forming, without complicated three-piece mould, coordinate.
For achieving the above object, the technical solution used in the present invention is:
A kind of electroacoustic transducer diaphragm sheet, one-body molded by metal, described vibrating diaphragm comprises flutter and support frame, and described flutter and support frame are all strip, described flutter one end and support frame inner side is connected, the flutter other end can be in support frame up-down vibration.
A kind of preferred version as electroacoustic transducer diaphragm sheet of the present invention, described flutter is connected with support frame by cantilever beam, described cantilever beam can be for single, cantilever beam is positioned at flutter link middle part, one end is connected the other end and is connected with support frame with flutter, flutter be subject to after external force can be in support frame up-down vibration, cantilever beam not only can well keep the relative position of flutter, the elastic-restoring force of cantilever beam determines that the vibration stiffness of vibrating diaphragm is stable and controlled simultaneously, and anti-fatigue ability is strong.Cantilever beam also can be for a plurality of, and preferred cantilever beam is two structures that structure is identical, is evenly distributed between flutter and support frame, makes to vibrate stiffness more stable.
A kind of preferred version as electroacoustic transducer diaphragm sheet of the present invention, described flutter is connected with support frame by crossbeam, described crossbeam middle part is connected with flutter, crossbeam two ends are connected with support frame respectively, flutter be subject to after external force can be in support frame up-down vibration, when flutter vibrates up or down, flutter by force transmission to crossbeam, at crossbeam two ends, form twisting resistance, because crossbeam two ends are fixedly connected with support frame, crossbeam produces restoring force and acts on flutter.Beam structure not only can well keep the relative position of flutter, and the elastic-restoring force of crossbeam determines that the vibration stiffness of vibrating diaphragm is stable and controlled simultaneously, and anti-fatigue ability is strong.
A kind of preferred version as electroacoustic transducer diaphragm sheet of the present invention, described vibrating diaphragm employing stainless steel or nickel are one time punching molded, can adopt continuous metal clicking technique to be made as material strip form, vibrating diaphragm is produced can automation, greatly reduced the cost of vibrating diaphragm, improving yield.
Beneficial effect:
Electroacoustic transducer diaphragm sheet of the present invention, is connected with support frame by cantilever beam or crossbeam, because support frame, cantilever beam or crossbeam are all made of metal, can well keep the relative position of flutter; The vibration stiffness of vibrating diaphragm is stable and controlled, and anti-fatigue ability is strong; Can adopt continuous metal clicking technique to be made as material strip form, vibrating diaphragm is produced can automation, has greatly reduced the cost of vibrating diaphragm, improving yield.
