[0020] Example 1

[0021] Reference Figures 1 to 4 This utility model provides a horn speaker, including a cabinet 1, a front panel 11 disposed on the front side of the cabinet 1, a horn sound-emitting unit 2 disposed on the front panel 11, a first circular sound-emitting unit 3, a second circular sound-emitting unit 4, a panel 5 connected to the front side of the front panel 11, and a wiring board 6 disposed on the rear side of the cabinet 1. The panel 5 is used to protect and limit the sound-emitting units, and the wiring board 6 is used to realize the electrical connection between the speaker and an external power amplifier and sound source. In this embodiment, the first circular sound-emitting unit 3 is a mid-high frequency unit, and the second circular sound-emitting unit 4 is a low frequency unit. The outer diameter of the first circular sound-emitting unit 3 is smaller than that of the second circular sound-emitting unit 4. In addition, a decorative ring is connected to the front side of the second circular sound-emitting unit 4. A recessed platform 12 matching the panel 5 is disposed on the front side of the front panel 11, and the panel 5 is installed in the recessed platform 12.

[0022] The upper side of the panel 5 protrudes rearward to form a receiving portion 51 for accommodating the horn-emitting unit 2. A receiving hole 52 is provided at the rear end of the receiving portion 51. The receiving portion 51 is horn-shaped, and its shape is adapted to the shape of the horn-emitting unit 2, allowing the horn-emitting unit 2 to be embedded within it. The diameter of the horn opening of the receiving portion 51 gradually increases from the rear end to the front end, with an expansion angle of 45°-65°, matching the sound wave radiation path of the horn-emitting unit 2 and reducing sound wave reflection loss within the receiving portion 51.

[0023] The inner walls of the receiving part 51 on both opposite sides are provided with limiting protrusions 53 for limiting the front bracket 21 of the horn sound-emitting unit 2. The limiting protrusions 53 can be integrally formed with the panel 5 (when the panel 5 is made of plastic) or fixed by welding (when the panel 5 is made of metal). The limiting protrusions 53 can limit the front bracket 21 in the left and right directions to prevent displacement during installation.

[0024] The horn-emitting unit 2 includes a front bracket 21, a fixed bracket 22, a cover plate 23, a magnet 24, and a rear seat 25 connected in sequence. The fixed bracket 22 is connected to the receiving hole 52 at the rear end of the receiving part 51.

The size of the elastic blocks 7 is adjusted according to the gap between the front bracket 21 and the receiving part 51. The elastic blocks 7 are attached to the surface of the front bracket 21 with high-temperature resistant adhesive. After installation, the elastic blocks 7 are in a slightly compressed state, which can absorb the vibration of the front bracket 21 during operation, prevent the vibration from being transmitted to the panel 5 and the housing 1, and provide vertical buffering and limiting for the front bracket 21, ensuring that the front bracket 21 can be stably positioned in the middle of the receiving part 51.

[0028] Two snap fasteners 221 are symmetrically arranged on the front side of the fixed bracket 22, and the inner wall of the receiving hole 52 of the receiving part 51 is provided with two locking parts 54 that respectively cooperate with the two snap fasteners 221. Specifically, during the assembly process, the front bracket 21 is inserted into the receiving part 51 from the front side until the rear end of the front bracket 21 enters the receiving hole 52. The fixed bracket 22 is connected to the rear end of the front bracket 21 from the rear side. After the connection is in place, the snap fasteners 221 are engaged with the locking parts 54. Alternatively, the fixed bracket 22 and the front bracket 21 can be pre-connected, and then the fixed bracket 22 and the front bracket 21 can be inserted into the receiving part 51 from the front side until the fixed bracket 22 and the receiving hole 52 are fitted together (at this time, the snap fasteners 221 are engaged with the locking parts 54). Then, another fastener is used to fix and limit the fixed bracket 22 to the rear end of the receiving hole 52 (the notch in the figure can be used as the limiting area).

[0029] The front panel 11 is provided with a first mounting hole 13, a second mounting hole 14, and a third mounting hole 15 arranged sequentially from top to bottom, with the central axis of each of the three mounting holes perpendicular to the front panel 11. The receiving part 51 is installed in the first mounting hole 13, the first circular sound-emitting unit 3 is installed in the second mounting hole 14, and the second circular sound-emitting unit 4 is installed in the third mounting hole 15. The front sides of both the second mounting hole 14 and the third mounting hole 15 are provided with a 2-5mm recessed step to facilitate the positioning of the first circular sound-emitting unit 3 and the second circular sound-emitting unit 4 during installation.

[0030] The panel 5 has a circular hole in the middle that matches the first circular sound-emitting unit 3, and an arc-shaped portion 55 at the lower end of the panel 5 that mates with the outer edge of the second circular sound-emitting unit 4. When the second circular sound-emitting unit 4 is installed into the third mounting hole 15, the arc-shaped portion 55 fits tightly against the outer edge of the unit.

[0031] Example 2

[0032] Reference Figure 1-3 5. This embodiment provides a horn speaker, including a cabinet 1, a front panel 11 disposed on the front side of the cabinet 1, a horn sound-emitting unit 2 disposed on the front panel 11, a first circular sound-emitting unit 3, a second circular sound-emitting unit 4, a panel 5 connected to the front side of the front panel 11, and a wiring board 6 disposed on the rear side of the cabinet 1. The panel 5 is used to protect and limit the sound-emitting units, and the wiring board 6 is used to realize the electrical connection between the speaker and an external power amplifier and sound source. In this embodiment, the first circular sound-emitting unit 3 is a mid-high frequency unit, and the second circular sound-emitting unit 4 is a low frequency unit. The outer diameter of the first circular sound-emitting unit 3 is smaller than that of the second circular sound-emitting unit 4. In addition, a decorative ring is connected to the front side of the second circular sound-emitting unit 4. A recessed platform 12 matching the panel 5 is disposed on the front side of the front panel 11, and the panel 5 is installed in the recessed platform 12.

[0033] The upper side of the panel 5 protrudes rearward to form a receiving portion 51 for accommodating the horn-emitting unit 2. A receiving hole 52 is provided at the rear end of the receiving portion 51. The receiving portion 51 is horn-shaped, and its shape is adapted to the shape of the horn-emitting unit 2, allowing the horn-emitting unit 2 to be embedded within it. The diameter of the horn opening of the receiving portion 51 gradually increases from the rear end to the front end, with an expansion angle of 45°-65°, matching the sound wave radiation path of the horn-emitting unit 2 and reducing sound wave reflection loss within the receiving portion 51.

[0034] The inner walls of the receiving part 51 on both opposite sides are provided with limiting protrusions 53 for limiting the front bracket 21 of the horn sound-emitting unit 2. The limiting protrusions 53 can be integrally formed with the panel 5 (when the panel 5 is made of plastic) or fixed by welding (when the panel 5 is made of metal). The limiting protrusions 53 can limit the front bracket 21 in the left and right directions to prevent displacement during installation.

[0035] The horn-emitting unit 2 includes a front bracket 21, a fixed bracket 22, a cover plate 23, a magnet 24, and a rear seat 25 connected in sequence. The fixed bracket 22 is connected to the receiving hole 52 at the rear end of the receiving part 51.

[0036] The front bracket 21 includes a horn-shaped bracket body 211 and a sound guide assembly 212 disposed inside the bracket body 211; the sound guide assembly 212 includes a plurality of sound guide plates connected to the bracket body 211.

[0037] Several of the aforementioned sound guide plates are arranged in a grid pattern. This includes two sound guide plates arranged vertically and one sound guide plate arranged horizontally. The grid design of the sound guide assembly 212 can evenly disperse sound waves to the horn mouth, reduce reflection and interference in the mid-to-high frequency range, and significantly improve the clarity and layering of the sound quality, clearly reproducing vocal details and instrument overtones.

[0038] Elastic blocks 7 are provided between the top of the front bracket 21 and the inner wall of the receiving part 51, and between the bottom of the front bracket 21 and the inner wall of the receiving part 51. In this embodiment, the elastic blocks 7 are made of EVA, but in specific implementations, the material of the elastic blocks 7 can also be silicone, nitrile rubber, or EPDM (for outdoor scenarios). The size of the elastic blocks 7 is adjusted according to the gap between the front bracket 21 and the receiving part 51. The elastic blocks 7 are attached to the surface of the front bracket 21 with high-temperature resistant adhesive. After installation, the elastic blocks 7 are in a slightly compressed state, which can absorb the vibration of the front bracket 21 during operation, prevent the vibration from being transmitted to the panel 5 and the housing 1, and provide vertical buffering and limiting for the front bracket 21, ensuring that the front bracket 21 can be stably positioned in the middle of the receiving part 51.

[0039] Two snap fasteners 221 are symmetrically arranged on the front side of the fixed bracket 22, and the inner wall of the receiving hole 52 of the receiving part 51 is provided with two locking parts 54 that respectively cooperate with the two snap fasteners 221. Specifically, during the assembly process, the front bracket 21 is inserted into the receiving part 51 from the front side until the rear end of the front bracket 21 enters the receiving hole 52. The fixed bracket 22 is connected to the rear end of the front bracket 21 from the rear side. After the connection is in place, the snap fasteners 221 are engaged with the locking parts 54. Alternatively, the fixed bracket 22 and the front bracket 21 can be pre-connected, and then the fixed bracket 22 and the front bracket 21 can be inserted into the receiving part 51 from the front side until the fixed bracket 22 and the receiving hole 52 are fitted together (at this time, the snap fasteners 221 are engaged with the locking parts 54). Then, another fastener is used to fix and limit the fixed bracket 22 to the rear end of the receiving hole 52 (the notch in the figure can be used as the limiting area).

[0040] The front panel 11 is provided with a first mounting hole 13, a second mounting hole 14, and a third mounting hole 15 arranged sequentially from top to bottom, with the central axis of each of the three mounting holes perpendicular to the front panel 11. The receiving part 51 is installed in the first mounting hole 13, the first circular sound-emitting unit 3 is installed in the second mounting hole 14, and the second circular sound-emitting unit 4 is installed in the third mounting hole 15. The front sides of both the second mounting hole 14 and the third mounting hole 15 are provided with a 2-5mm recessed step to facilitate the positioning of the first circular sound-emitting unit 3 and the second circular sound-emitting unit 4 during installation.

[0041] The lower end of the panel 5 is provided with an arc-shaped portion 55 that mates with the outer edge of the second circular sound-emitting unit 4. After the second circular sound-emitting unit 4 is installed into the third mounting hole 15, the arc-shaped portion 55 fits tightly against the outer edge of the unit.

[0042] The inner wall of the receiving hole 52 is provided with a limiting pin 56, and the side wall of the fixed bracket 22 is provided with a limiting groove 222 that cooperates with the limiting pin 56. The limiting groove 222 is L-shaped. Specifically, in this embodiment, the fixed bracket 22 is generally disc-shaped. One end of the limiting groove 222 is arranged along the axial direction of the fixed bracket 22, and the other end is arranged along the outer wall (defined as a transverse limiting groove). The axial end of the limiting groove 222 extends to the front end face of the fixed bracket 22. During assembly, the limiting pin 56 can be aligned with the axial limiting groove 222 until the limiting pin 56 is fully inserted into the starting end of the transverse limiting groove (at this time, the buckle 221 is just engaged with the snap-fit ​​part 54). Then, the fixed bracket 22 is rotated by a set angle (which can be clockwise or counterclockwise depending on the position of the transverse limiting groove) so that the limiting pin 56 moves to the end of the transverse limiting groove, thus completing the connection. The cooperation between the limiting pin 56 and the limiting groove 222 ensures that the horn sound-emitting unit 2 will not move in the front-back direction. The connection between the fixed bracket 22 and the panel 5 does not require tools, resulting in high assembly efficiency. At the same time, the limiting protrusion 53 and the elastic block 7 can assist the front bracket 21 in quick positioning, avoiding installation misalignment and further improving assembly accuracy.
