Description

Technical Field

[0001] The utility model relates to the technical field of speakers, and particularly relates to a high sound pressure speaker structure. Background Art

[0002] However, the structure of the existing speakers generally includes a chassis and a speaker disposed on the chassis. For example, the utility model with the publication number "CN221043176U" and the name "Speaker and Headphone with the Speaker" discloses a speaker and a headphone with the speaker. The speaker includes a chassis and a vibration assembly. The chassis includes a bearing portion and a limiting portion disposed around the bearing portion; the vibration assembly is disposed inside the chassis and includes a diaphragm and an assembly portion connected to the edge of the diaphragm. The assembly portion is disposed on the bearing portion and surrounded by the limiting portion. Although it can achieve a sound effect, the sound pressure of this speaker is not very high, and the sound propagation effect and sound quality performance are not very ideal. Therefore, it is necessary to develop a high sound pressure speaker structure that can increase the sound pressure and improve the sound effect. Content of the Utility Model

[0003] Aiming at the above deficiencies, the purpose of the utility model is to provide a high sound pressure speaker structure with reasonable structural design and capable of increasing the sound pressure.

[0004] To achieve the above purpose, the technical solution provided by the utility model is:

[0005] A high sound pressure speaker structure, which includes a chassis, a speaker and a sound pressure cover disposed on the chassis. The sound pressure cover is covered on the chassis corresponding to the front position of the diaphragm of the speaker. The sound pressure cover is provided with a conical shell protruding towards the diaphragm, and a plurality of arc-shaped slot holes are distributed on the conical shell.

[0006] As a preferred solution of the utility model, a lower convex strip is provided on the lower edge of the inner side of the arc-shaped slot hole, and an upper convex strip is provided on the upper edge opposite to the inner side of the arc-shaped slot hole, which can further increase the sound pressure and thus improve the sound pressure.

[0007] As a preferred solution of the utility model, a plurality of the arc-shaped slot holes are centrosymmetric, and the centrosymmetric design helps to achieve a more uniform sound field distribution, reduce sound distortion and phase problems.

[0008] As a preferred solution of the utility model, a plurality of the arc-shaped slot holes form a plurality of sound output rings with different diameters and concentric settings, which can achieve layered diffusion of sound and enhance the sense of hierarchy and spatial sense of sound.

[0009] As a preferred solution of the utility model, radial spokes are provided on the upper surface of the conical shell to increase the structural stability and prevent deformation caused by vibration.

[0010] As a preferred embodiment of the present utility model, an arc-shaped convex rib is provided at the peripheral position of the upper surface of the sound pressure cover, which enhances the rigidity of the sound pressure cover, reduces the noise generated during vibration, and has a certain protective effect.

[0011] As a preferred embodiment of the present utility model, the taper of the conical shell is greater than that of the diaphragm. The conical shell helps to direct the sound wave energy more concentratedly forward, thereby enhancing the directivity and focusing effect of the sound, and increasing the sound pressure.

[0012] As a preferred embodiment of the present utility model, a ring-shaped insertion tongue is provided at the peripheral position of the lower surface of the sound pressure cover, and a ring-shaped slot adapted to the ring-shaped insertion tongue is provided on the speaker frame. By designing the insertion method of the ring-shaped insertion tongue and the ring-shaped slot, the sound pressure cover and the speaker frame can be quickly and firmly connected. This design not only simplifies the assembly process but also improves the overall stability and reliability of the product.

[0013] As a preferred embodiment of the present utility model, grooves are provided on the inner wall of the ring-shaped insertion tongue along its circumferential direction. Glue can be applied in the grooves to further enhance the connection firmness between the insertion tongue and the slot, preventing loosening due to vibration during use.

[0014] The beneficial effects of the present utility model are as follows: The structure of the present utility model is reasonably designed, and a sound pressure cover is added. A conical shell and an arc-shaped slot are provided on the sound pressure cover, enabling the air squeezed by the diaphragm of the speaker to accelerate the air flow rate when passing through the smaller and narrower arc-shaped slot, thereby significantly increasing the acoustic resistance. Moreover, this process does not rely on additional vibration mass to limit the vibration speed, directly promoting the enhancement of the speaker sound pressure. At the same time, under the action of the conical reflection structure of the conical shell, the sound is diffused from a small space to a large space, making the sound more concentrated and sent in a specific direction, enabling the sound to be transmitted farther, more clearly, and more powerfully, effectively improving the sound quality and the sound propagation effect.

[0020] See Figures 1 to 4 A high sound pressure horn structure provided in this embodiment includes a chassis 1, a horn 2 and a sound pressure cover 3 disposed on the chassis 1. The sound pressure cover 3 is disposed on the chassis 1 corresponding to the front position of the diaphragm 21 of the horn 2.

[0021] A conical shell 31 protruding towards the diaphragm 21 is provided on the sound pressure cover 3. The taper of the conical shell 31 is preferably greater than the taper of the diaphragm 21. In this embodiment, the taper of the conical shell 31 is preferably 119 degrees, and the taper of the diaphragm 21 is preferably 115 degrees. This helps to direct the acoustic energy more concentratedly forward, thereby enhancing the directivity and focusing effect of the sound and increasing the sound pressure. Radial spokes 32 are provided on the upper surface of the conical shell 31 to increase the structural stability and prevent deformation caused by vibration. An arc-shaped rib 33 is provided at the peripheral position of the upper surface of the sound pressure cover 3 to enhance the rigidity of the sound pressure cover 3, reduce the noise generated during vibration, and have a certain protective effect.

[0022] A number of arc-shaped slot holes 34 are distributed on the conical shell 31. Preferably, a lower convex strip 341 is provided at the lower edge of the inner side of the arc-shaped slot hole 34, and an upper convex strip 342 is provided at the upper edge opposite to the inner side of the arc-shaped slot hole 34, which can further increase the sound pressure, thereby increasing the sound pressure.

[0023] Preferably, a number of the arc-shaped slot holes 34 are centrosymmetric. The centrosymmetric design helps to achieve a more uniform sound field distribution, reduce sound distortion and phase problems. A number of the arc-shaped slot holes 34 form a plurality of sound-emitting rings with different diameters and concentric settings, which can achieve layered diffusion of sound and enhance the sense of hierarchy and space of the sound.

[0024] For convenient assembly, a ring-shaped tongue 35 is provided at the peripheral position of the lower surface of the sound pressure cover 3, and a ring-shaped slot 11 adapted to the ring-shaped tongue 35 is provided on the chassis 1. Preferably, a groove is provided on the inner wall of the ring-shaped tongue 35 along its circumferential direction. Glue can be applied in the groove to further improve the connection firmness between the tongue and the slot and prevent loosening due to vibration during use. During installation, by inserting the ring-shaped tongue 35 into the ring-shaped slot 11, the sound pressure cover 3 and the chassis 1 can be quickly and firmly connected.

[0025] During operation, through the combination of the conical shell 31 and the arc-shaped slot hole 34, the air generated by the diaphragm 21 of the speaker 2 being squeezed can accelerate the air flow rate when passing through the smaller and narrower arc-shaped slot hole 34, thereby doubling the acoustic resistance. Moreover, there is no need for a vibration mass to limit the vibration speed, so that the sound pressure of the speaker 2 can be increased by about 13 dB on the traditional basis, and the overall sound pressure can reach more than 98 dB at 1W / 1m. In addition, with the action of the conical reflection structure of the conical shell 31, the sound is diffused from a small space to a large space, making the sound propagation direction clearer and more concentrated, and the directivity is significantly enhanced, ensuring that the sound can be transmitted over a long distance without losing its clarity and strength, enabling users to enjoy a better sound quality experience.
