[0031] Embodiment 1:

[0032] This embodiment relates to a multi-channel speaker, as Figure 1-6 shown, including: a bottom case 100, a plurality of sound generating units 200, and a sound guide plate 300.

[0033] A chassis 400 is disposed above the bottom case 100, and a plurality of mounting positions for mounting the sound generating units 200 are provided on the chassis 400. The plurality of sound generating units 200 are mounted on the chassis 400, wherein at least one sound generating unit 200 is detachably mounted on the chassis 400. The user can replace the detachable sound generating unit 200 according to the required audio effect, so as to adjust the audio effect without changing the overall structure of the speaker and the electronic layout of the audio system, and ensure the sound quality performance of the speaker. The adjustability of the speaker is high, and a diversified usage experience can be provided.

[0034] The sound guide plate 300 is detachably installed above the bottom shell 100, which can protect the sound generating unit 200 and guide the sound emitted by the sound generating unit 200. A plurality of sound guide holes 310 are provided on the sound guide plate 300 corresponding to the sound generating unit 200 for guiding the sound emitted by the sound generating unit 200. The plurality of sound guide holes 310 are independent of each other, which can avoid the interference of the sounds emitted by the plurality of sound generating units 200, reduce the occurrence of co-frequency resonance, and improve the clarity and stability of the overall sound quality of the speaker.

[0035] In this embodiment, a sound channel isolation structure 320 is provided on the sound guide plate 300 and between two adjacent sound guide holes 310 to further avoid the interference of sounds between two adjacent sound guide holes 310. As a preferred solution, the sound channel isolation structure 320 is a triangular column provided between two adjacent sound guide holes 310. The triangular column has good stability, can avoid the deformation of the sound guide holes 310, can well isolate the audio of adjacent sound generating units 200, effectively reduce the co-frequency resonance between the two, reduce sound wave interference and distortion, and improve the clarity and stability of the overall sound quality of the speaker. Of course, in other embodiments, the sound channel isolation structure 320 can also be set in other shapes to achieve a good isolation effect.

[0036] The sound guide plate 300 and the bottom shell 100 are detachably installed. The user can disassemble the sound guide plate 300 to facilitate the replacement of the sound generating unit 200 inside the speaker and meet different listening requirements. At the same time, it is convenient for the user to clean the sound guide plate 300, avoid the dust on the sound guide plate 300 from affecting the sound quality of the speaker, or replace different types of sound guide plates 300 to achieve different sound guiding effects. In this embodiment, a plurality of plug-in columns 330 are provided on the surface of the sound guide plate 300 close to the bottom shell 100, and a plurality of plug-in holes 410 are provided on the basin frame 400 corresponding to the plug-in columns 330. The sound guide plate 300 is detachably installed on the bottom shell 100 through the cooperation of the plug-in columns 330 and the plug-in holes 410, and the disassembly and assembly of the sound guide plate 300 can be realized without tools, which is more convenient for the user to operate. As a preferred solution, the plug-in holes 410 are provided on the basin frame 400 and between two sound generating units 200, so that the sound guide plate can be well combined with the basin frame 400 between the plurality of sound generating units 200, thereby avoiding the interference between the sound generating units 200 and improving the clarity and stability of the overall sound quality of the speaker. Of course, in other embodiments, other structures can also be used to realize the detachable installation between the sound guide plate 300 and the bottom shell 100.

[0037] In this embodiment, insertion edges 340 are provided at both ends of the sound guide plate 300, and insertion slots 420 corresponding to the insertion edges 340 are provided on the chassis 400. The insertion plate can be inserted into the insertion slots 420 to form an isolation edge at both ends of the sound guide plate 300, preventing sound from leaking through the gap between the sound guide plate 300 and the chassis 400, avoiding the occurrence of sound leakage, and ensuring the sound quality of the speaker. As a preferred solution, the chassis 400 is detachably mounted on the bottom case 100. A circular mounting groove 440 is provided on the peripheral side of the bottom of the chassis 400, and a mounting edge 430 corresponding to the mounting groove 440 is provided on the bottom case 100. The chassis 400 is detachably mounted on the bottom case 100 through the cooperation of the mounting groove 440 and the mounting edge 430. The detachable structure of the chassis 400 and the bottom case 100 enables the chassis 400 to be detached as a whole, which not only facilitates the maintenance of the inside of the speaker, but also enables different chassis 400 to be replaced to adjust the overall effect of the speaker, further improving the adjustability of the speaker and providing a diverse usage experience.

[0038] In this embodiment, the sound guide plate 300 gradually contracts from the side close to the chassis 400 to the side far from the chassis 400. A sound guide arc surface 350 is provided on one side of the sound guide plate 300, so that the sound emitted by the sound generating unit 200 will be effectively concentrated by the sound guide holes 310 of the sound guide plate 300 and then propagate in a set direction, reducing the ineffective scattering of sound waves and achieving the effect of directional sound emission, optimizing the sound quality and usage experience of the speaker. At the same time, the outer contraction structure of the sound guide plate 300 optimizes the external shape design of the speaker, reduces the outer width of the sound guide plate 300, and improves the aesthetics and compactness of the speaker.

[0039] In this embodiment, multiple sound generating units 200 are arranged and mounted on the chassis 400 in a straight line, so that the sound generating effects of the multiple sound generating units 200 are better and the interference between them is less. Effectively reducing the co-frequency resonance between the sound generating units 200, reducing the sound wave interference and distortion of the sound generating units 200, and improving the clarity and stability of the overall sound quality of the speaker. As a preferred solution, the sound generating unit 200 includes: a high-frequency unit 210, a replaceable unit 220, and a full-frequency unit 230 disposed between the high-frequency unit 210 and the replaceable unit 220. The replaceable unit 220 is detachably mounted on the chassis 400. The user can replace the replaceable unit 220 as needed, such as a bass unit, a subwoofer unit, or a midrange unit, a mid-high frequency unit 210, to meet different listening needs. Of course, in other embodiments, the sound generating unit 200 can also be provided with other numbers, configuration combinations, and mounting positions.
