Embodiment 1

[0042] Such as Figure 1~6 As shown, Embodiment 1 of the present invention provides a metal diaphragm 21, which includes a hemispherical film part 211 with a convex middle part. The periphery of the hemispherical film part 211 extends along the horizontal direction to form an annular flat film part 212. The peripheral edge of the membrane portion 212 is folded toward the convex direction of the hemispherical membrane portion 211 and extends away from the hemispherical membrane portion 211 to form a trumpet-shaped membrane portion 213. The height of the spherical top of the film-shaped portion 211.

[0043]The metal diaphragm 21 of this embodiment, because its hemispherical film part 211 is the hemispherical structure that the central part protrudes outward, when the metal diaphragm 21 vibrates, the hemispherical film part 211 will vibrate and act on the ring in the middle. Shaped flat film portion 212 deviates from the first force of the hemispherical film portion 211; at the...

Embodiment 2

[0053] Such as Figure 3-6 As shown, Embodiment 2 of the present invention provides a speaker. The speaker of this embodiment includes a magnetic circuit system 10, a vibration system 20, a speaker bracket 30, and the metal diaphragm 21 in the first embodiment above. The speaker bracket 30 includes a basin frame 32 and U cup 31, the basin frame 32 and U cup 31 are fastened and connected with each other and form an installation cavity together, the magnetic circuit system 10 and the vibration system 20 are fixed in the installation cavity, and the trumpet-shaped membrane part of the metal diaphragm 21 The peripheral edge of 213 away from the hemispherical membrane part 211 is fixedly connected with the frame 32 .

[0054] The loudspeaker of this embodiment uses the above-mentioned metal diaphragm 21, the split vibration at high frequencies is reduced, and the high-frequency curve becomes smoother, which improves the sensitivity of the sound of the loudspeaker and improves the u...

Abstract

The invention belongs to the field of electroacoustic products, and particularly relates to a metal vibrating diaphragm and a loudspeaker. The metal vibrating diaphragm comprises a dome-shaped hemispherical diaphragm part; the periphery of the semispherical film part extends in the horizontal direction to form an annular flat film part, the periphery of the annular flat film part is turned over inthe protruding direction of the semispherical film part and continues to extend away from the semispherical film part to form a horn-shaped film part, and the height of the outer periphery, away fromthe semispherical film part, of the horn-shaped film part is larger than that of the dome of the semispherical film part. When the metal vibrating diaphragm vibrates, the force which enables the metal vibrating diaphragm to deform can be partially or completely counteracted. The metal vibrating diaphragm is prevented from deforming, so that the rigidity of the metal vibrating diaphragm is improved, the thickness of the metal vibrating diaphragm is reduced and the damping characteristic of the metal vibrating diaphragm is improved under the condition of certain rigidity, the segmentation distortion of the metal vibrating diaphragm at high frequency is weakened, and the normal vibration sounding of the metal vibrating diaphragm is ensured.

Description

technical field [0001] The invention belongs to the technical field of electroacoustic products, and in particular relates to a metal diaphragm and a loudspeaker. Background technique [0002] In recent years, due to the increasing requirements of the market for the functional characteristics of the speaker, the diaphragm is one of the main components of the speaker's vibration and sound, and its quality largely determines the effective frequency range, distortion and sound quality of the speaker. Key design controls for speaker sound. However, the performance of the diaphragm depends on the geometric shape and material of the diaphragm. The traditional diaphragm is generally designed as a linear structure or a cone-shaped basin structure. The material is mostly made of paper, plastic or aluminum and aluminum alloy. Materials such as materials, but the rigidity of the diaphragm of this type of structure or material is not enough, which makes the speaker prone to split vibra...
