Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and more particularly to a vibration sound-generating structure of a loudspeaker. Background Art

[0002] The quality of headphone sound is influenced by a variety of factors. Firstly, sound quality is a key factor, encompassing aspects such as frequency response, distortion, and dynamic range. Headphone design and manufacturing quality also significantly impact sound quality. The driver unit, material selection, and circuit design all directly influence sound transmission and performance. Wearing comfort also plays a crucial role.

[0003] As an important component of audio equipment, the performance and quality of the diaphragm will directly affect the listening experience. When selecting a diaphragm, it is necessary to make comprehensive considerations based on actual needs and application scenarios.

[0004] The diaphragm of a traditional speaker uses a single rubber material as the resonance carrier, commonly known as the "rubber surround." This is first molded and then glued and pressure-laminated by the body manufacturer. Currently, due to limitations in the production and lamination process, the bond strength is unstable. Therefore, the only way to improve quality has been to develop and apply glue and improve the bonding of the rubber surround.

[0005] Therefore, based on the traditional rubber diaphragm, a vibration sound-generating structure of a loudspeaker with a discontinuously smooth surface was developed. Utility Model Content

[0006] In view of this, the utility model provides a vibration sound-generating structure of a loudspeaker.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a vibration sound-generating structure of a speaker, comprising: a support part and a carcass, the carcass is arranged to bulge in an arc shape upward relative to a horizontal plane, and the support part is arranged to extend outward around the outer edge of the carcass; the upper surface of the carcass is provided with multiple circles of annular upper grooves, and annular upper protrusions are formed between adjacent upper grooves; the upper grooves and the upper protrusions are arranged alternately.

[0008] As a preferred solution of the present invention, the center of the upper groove, the center of the upper protrusion and the vertex of the carcass are on the same axis.

[0009] As a preferred solution of the present invention, a lower protrusion is formed on the lower surface of the carcass corresponding to the upper groove position of the upper surface, and a lower groove is formed on the lower surface of the carcass corresponding to the upper protrusion position of the upper surface.

[0010] As a preferred solution of the present invention, the carcass is made of magnesium-aluminum alloy.

[0011] As a preferred solution of the present invention, the support portion and the carcass are integrally formed of magnesium-aluminum alloy.

[0012] As a preferred solution of the present invention, the support portion extends horizontally outward along the outer edge of the carcass.

[0013] It can be seen from the above technical solution that compared with the existing technology, the utility model has the following beneficial technical effects: the vibration and sound-generating structure of the loudspeaker is made of magnesium-aluminum alloy in one piece. Since the mass and density of magnesium-aluminum alloy are relatively large, it is more rigid than traditional plastic diaphragms and the sound quality is more stable; in addition, the vibration and sound-generating structure of the loudspeaker made of magnesium-aluminum alloy has very good high-frequency performance and resolution.
