Problems solved by technology

[0005] In view of the miniaturization and thinning design of all kinds of electronic products nowadays, all the loudspeaker design companies are thinking hard about how to reduce or shrink the components without affecting their acoustic performance, or even produce better sound quality. In addition, since the diaphragm must be closely combined with the voice coil to be driven, a processing process must be added between the two, which is also a cost-intensive part, so how to design It is an important issue to further save the use of components by using a diaphragm with multiple functions

Embodiment Construction

[0037] In order to further explain the technical means and effects that the present invention takes to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, steps, features and features of the magnetic diaphragm proposed according to the present invention will be described below. Efficacy, detailed as follows.

[0038] A magnetic diaphragm according to a preferred embodiment of the present invention will be described below with reference to related drawings.

[0039] The present invention discloses a magnetic vibrating membrane, which is used to be installed in an electroacoustic converter such as a speaker. When used in a speaker, the speaker generates a magnetic field with an electrical signal to cause the vibrating membrane to vibrate and emit a sound signal; The magnetic vibrating film of the present invention has a vibrating film base material, and a magnetic ma...

Abstract

The invention relates to a magnetic diaphragm, which is arranged in an electro-acoustic converter. The magnetic diaphragm is provided with a diaphragm substrate, a magnetic material is deposited on the diaphragm substrate by using a film deposition method to form a magnetic layer, therefore, the diaphragm substrate has magnetic property as the magnetic layer is arranged, so that magnetic representation is generated between the magnetic diaphragm and a magnetic circuit arranged in the electro-acoustic converter.

Description

technical field [0001] The invention relates to a magnetic vibrating film, in particular to a magnetic vibrating film in which a magnetic layer is formed on a vibrating film base material by a film deposition method. Background technique [0002] In recent years, music files have developed a file format that greatly reduces the amount of audio data, and the playback sound quality of such files has not significantly decreased compared with the original uncompressed audio, which will not affect the hearing experience of most users. Therefore, music players are mass-produced at present, and the speakers responsible for playing music files are the key components of the sound output. The quality and design of the speakers are usually the same for each music player manufacturer. most concerned and focused. [0003] see figure 1 As shown, the figure discloses a prior known loudspeaker 10, the loudspeaker 10 is made up of a housing 11, a lower yoke plate 12, an upper yoke plate 13...
