Embodiment Construction

[0038] Please also refer to Figure 1~2 , the diaphragm 100 according to the preferred embodiment of the present invention is used in a sound module (not shown) of an electronic device (not shown). The electronic device can be an electronic device capable of producing sound, such as a computer, a mobile phone, an earphone, and an electronic reader. The diaphragm 100 includes a dome top 10 having a dome shape and a ring portion 20 extending from the outer periphery of the dome top 10 and surrounding the dome top 10 . The ball top 10 includes two resin layers 12 and a metal layer 11 sandwiched between the two resin layers 12 .

[0039] see figure 2 , the ball top 10 has two opposite first arcuate surfaces 101 , so that the ball top 10 forms a first arcuate groove 102 . The dome 10 has a central area 103 and a peripheral area 104 surrounding the central area 103 .

[0040] The size of the metal layer 11 is smaller than the size of each resin layer 12, so that the metal layer...

Abstract

A diaphragm comprises a globe roof part in a globe roof shape and a surround part extending from the outer circumference of the globe roof part to surround the globe roof part, wherein the globe roof part comprises two resin layers and a metal layer clamped between the two resin layers. Through arranging the metal layer in the globe roof part, the rigidity of the globe roof part is greatly improved, obvious differences exist between the rigidity of the globe roof part and the rigidity of the surround part, high and low pitch requirements of the diaphragm can be met, and the sound effects of the diaphragm are effectively improved. Besides, the invention also provides a method of manufacturing the above diaphragm, a sound module to which the above diaphragm is applied, and an electronic device to which the above sound module is applied.

Description

technical field [0001] The invention relates to a diaphragm and a preparation method thereof, a sound module using the diaphragm and an electronic device using the sound module. Background technique [0002] In recent years, with the rapid development of electronic products such as mobile phones, electronic products with better sound effects are favored by consumers. The sound module of electronic products is the main sound-generating component. Its sound-generating principle is mainly that the energized coil moves in a magnetic field environment, driving the diaphragm connected to it to vibrate, and when the diaphragm vibrates, it drives the air around it to vibrate, thereby producing Sound, therefore, the shape design and material characteristics of the diaphragm are the main factors that determine the sound effect of the sound module. [0003] Currently commonly used diaphragms include paper diaphragms, polymer diaphragms, metal diaphragms, and synthetic fiber diaphragms...
