Description

Technical Field

[0001] This utility model relates to the technical field of audio equipment, and in particular to an acoustic cavity structure. Background Technology

[0002] Acoustic cavity structures are used in electronic products such as televisions, computers, and automotive equipment. However, when existing acoustic cavity structures are integrated into these devices, they are prone to interference with the sound outlet of the acoustic cavity structure, making it difficult to implement traditional forward sound output solutions. Existing solutions often use physical shielding or simple reflective surfaces to change the sound wave path, but such designs are prone to problems such as sound wave diffraction and phase interference, resulting in high-frequency response distortion and blurred sound image positioning. Utility Model Content

[0003] The main purpose of this invention is to propose an acoustic cavity structure that aims to change the sound output direction of the acoustic cavity structure and reduce the interference to the acoustic cavity structure.

[0004] To achieve the above objectives, the acoustic cavity structure proposed in this utility model includes:

[0005] A housing having an internal mounting cavity, and a tweeter and a woofer on the housing;

[0006] A loudspeaker, mounted on the housing and located within the mounting cavity, the loudspeaker and the housing forming a sound outlet cavity, the sound outlet cavity communicating with the tweeter and the woofer; and

[0007] A guide bracket has a sound-guiding cavity formed inside it, which is connected to the tweeter. The guide bracket is installed on the housing and is inclined relative to the housing, away from the end face of the housing, so as to change the sound output direction of the tweeter.

[0008] In one embodiment, the angle between the end face of the guide bracket away from the housing and the mounting surface between the housing and the guide is α, where 10°≤α≤30°.

[0009] In one embodiment, the spacing of the sound guiding cavities gradually increases along the thickness direction of the guide bracket.

[0010] In one embodiment, the housing is provided with a first mounting portion, and the guide bracket is provided with a second mounting portion. The guide bracket is detachably connected to the housing through the second mounting portion and the first mounting portion.

[0011] In one embodiment, the first mounting portion is a first mounting hole, the second mounting portion is a second mounting hole, and the guide bracket is mounted on the housing by means of a screw connection that engages with the first mounting hole and the second mounting hole.

[0012] In one embodiment, both the first mounting hole and the second mounting hole are provided in multiples at intervals, with one first mounting hole corresponding to one second mounting hole.

[0013] In one embodiment, the guide bracket is confined within the housing.

[0014] In one embodiment, the housing is provided with a first limiting groove, which is adapted to the shape of the guide bracket so that the guide bracket is limited to the first limiting groove.

[0015] In one embodiment, the housing is provided with a second limiting groove, the second limiting groove is disposed on the bottom wall of the first limiting groove, the tweeter outlet is disposed on the groove wall of the second limiting groove, and the guide bracket is provided with a limiting protrusion, the limiting protrusion being limited within the second limiting groove.

[0016] In one embodiment, the guide bracket is sealed to the housing.

[0017] The acoustic cavity structure in this utility model includes a housing, a speaker, and a guide bracket. The housing has a mounting cavity, and a tweeter and a woofer are provided on the housing. The speaker is mounted on the housing and located within the mounting cavity.

[0029] Reference Figures 1 to 3 This utility model proposes an acoustic cavity structure, comprising:

[0030] The housing 10 has an installation cavity formed inside it, and the housing 10 is provided with a tweeter 11 and a woofer 12.

[0031] A loudspeaker, mounted on the housing 10 and located within the mounting cavity, the loudspeaker and the housing 10 forming a sound outlet cavity, the sound outlet cavity communicating with the tweeter 11 and the woofer 12; and

[0032] A guide bracket 20 is provided, in which a sound guiding cavity 21 is formed. The sound guiding cavity 21 is connected to the tweeter 11. The guide bracket 20 is installed on the housing 10, and the guide bracket 20 is inclined relative to the housing 10 and away from the end face of the housing 10, so as to change the sound output direction of the tweeter 11.

[0033] The acoustic cavity structure in this utility model includes a housing 10, a speaker, and a guide bracket 20. The housing 10 has an installation cavity, and a tweeter 11 and a woofer 12 are provided on the housing 10. The speaker is installed in the housing 10 and located within the installation cavity. The speaker and the housing 10 together form a sound outlet cavity, which communicates with the tweeter 11 and the woofer 12. The guide bracket 20 has a sound guide cavity 21, which communicates with the tweeter 11. The guide bracket 20 is installed in the housing 10, and is tilted relative to the housing 10, away from its end face, to change the sound output direction of the tweeter 11. This facilitates the installation of the acoustic cavity structure with the entire device. Furthermore, by setting the guide bracket 20, sound wave diffraction and phase interference are reduced, thereby reducing interference to the acoustic cavity structure. This facilitates the installation of the acoustic cavity structure while minimizing overall interference to the sound output of the acoustic cavity structure.

[0034] Furthermore, the angle between the end face of the guide bracket 20 facing away from the housing 10 and the mounting surface between the housing 10 and the guide is α, where 10°≤α≤30°. By further optimizing the tilt angle of the end face of the guide bracket 20, the sound output direction of the tweeter 11 is further adjusted, thereby further reducing problems such as sound wave diffraction and phase interference, thus reducing interference to the acoustic cavity structure and improving the sound effect of the acoustic cavity structure.

[0035] Reference Figure 1 , Figure 2 as well as Figure 4Specifically, the spacing of the sound-conducting cavities 21 gradually increases along the thickness direction of the guide bracket 20. This gradually increases the sound output surface of the tweeter 11, thereby increasing the sound output range at the opening of the sound-conducting cavity 21 within the guide bracket 20, thus improving the high-frequency propagation range of the acoustic cavity structure and ultimately enhancing the sound output effect of the acoustic cavity structure.

[0036] Reference Figures 1 to 4 In one embodiment, the housing 10 is provided with a first mounting portion, and the guide bracket 20 is provided with a second mounting portion. The guide bracket 20 is detachably connected to the housing 10 via the second mounting portion and the first mounting portion. By providing the first and second mounting portions, the connection strength between the guide bracket 20 and the housing 10 is improved, thereby enhancing the stability and reliability of the guide bracket 20 and reducing the possibility of loosening. Simultaneously, by detachably connecting the guide bracket 20 to the housing 10, the installation and disassembly of the guide bracket 20 are facilitated, making it easier to replace guide brackets 20 with different tilt angles, thus improving the efficiency of installation and disassembly of the guide bracket 20.

[0037] Specifically, the first mounting part is a first mounting hole 13, and the second mounting part is a second mounting hole 22. The guide bracket 20 is mounted to the housing 10 via screw fasteners that engage with the first mounting hole 13 and the second mounting hole 22. The installation method using screw fasteners with the first mounting hole 13 and the second mounting hole 22 is simple, requiring only a screwdriver to install and remove the guide bracket 20, thus improving the efficiency of installation and removal. Simultaneously, the screw fastener installation method is stable and reliable, thereby improving the stability of the guide bracket 20.

[0038] Furthermore, multiple first mounting holes 13 and second mounting holes 22 are provided at intervals, with one first mounting hole 13 corresponding to one second mounting hole 22. By providing multiple first mounting holes 13 and second mounting holes 22, the guide bracket 20 can be installed and fixed from different directions, thereby further improving the stability and reliability of the guide bracket 20.

[0039] In one embodiment, the guide bracket 20 is confined within the housing 10. It is understood that confining the guide bracket 20 within the housing 10 further increases the connection strength of the guide bracket 20 and further improves its stability.

[0040] Specifically, the housing 10 is provided with a first limiting groove 14, which is adapted to the shape of the guide bracket 20 so that the guide bracket 20 is confined within the first limiting groove 14. It can be understood that by setting the first limiting groove 14, the guide bracket 20 can be both limited and positioned. That is, when installing the guide bracket 20, there is no need to align the first mounting hole 13 and the second mounting hole 22; simply placing the guide bracket 20 within the first limiting groove 14 will align the first mounting hole 13 with the corresponding second mounting hole 22, thus facilitating the installation and fixing of the guide bracket 20 and improving the installation efficiency of the guide bracket 20.

[0041] Furthermore, the housing 10 is provided with a second limiting groove 15, which is located on the bottom wall of the first limiting groove 14. The tweeter outlet is located on the groove wall of the second limiting groove 15. The guide bracket 20 is provided with a limiting protrusion, which is located within the second limiting groove 15. By setting the cooperation between the second limiting groove 15 and the limiting protrusion, the stability of the guide bracket 20 is further improved, thereby further limiting the possibility of loosening of the guide bracket 20 and improving the reliability of the guide bracket 20. At the same time, the second limiting groove 15 and the limiting protrusion are located at the tweeter outlet 11, thereby improving the stability and reliability of the guide bracket 20 at the tweeter outlet 11, reducing the volume leakage at the tweeter outlet 11, and thus improving the sound effect of the acoustic cavity structure.

[0042] In one embodiment, the guide bracket 20 is sealed to the housing 10. By sealing the guide bracket 20 to the housing 10, leakage of sound from the tweeter 11 is reduced, thereby improving the sound output at the outlet of the sound guide cavity 21 inside the guide bracket 20. The sealing connection between the guide bracket 20 and the housing 10 can be achieved by silicone adhesive bonding or by sandwiching a sealing ring between the guide bracket 20 and the housing 10.

[0043] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
