Description

Technical Field

[0001] This utility model relates to the field of speakers, and in particular to a high-frequency amplification structure for high-power speaker arrays. Background Technology

[0002] Existing high-power speakers are mainly used in large-scale events such as outdoor performances, parties, and lectures. Their structure is similar to common speaker enclosures, including high- and low-frequency drivers, an external frame, and various internal components.

[0003] The high-frequency noise issue in high-power speakers remains a major problem plaguing the industry. This noise not only affects the listening experience, but over time it can further damage the drivers and significantly shorten the speaker's lifespan.

[0004] The main reason for this is the loose mounting structure of the high-frequency unit in high-power loudspeakers on the market. Structurally, it uses a traditional method of fixing one side of the unit inside the speaker enclosure, such as through gluing or welding, while the other side is directly exposed to the outside. Furthermore, because high-power loudspeakers differ from traditional loudspeakers, with their large transient impulses and high amplitudes, traditional unit assembly structures are no longer sufficient.

[0005] In view of this, this technical solution proposes a high-frequency amplification structure for high-power speaker groups. It adopts a different form from the traditional single-sided fixing form of conventional speakers. The diaphragm is fixed by a two-sided clamping structure. Several protective structures are also set in the direction close to the outside, which can eliminate the problem of burr noise to the greatest extent. The overall structure is simple, easy to assemble, and has a long service life. Utility Model Content

[0006] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a high-frequency amplification structure for high-power speaker arrays, aiming to solve the problems of high-frequency units in existing high-power speakers easily exhibiting harsh noise and having short service life.

[0007] To achieve the above objectives, this utility model provides a high-frequency amplification structure for a high-power speaker assembly, including a high-frequency unit assembly disposed on one side of the speaker body and communicating with the inner cavity of the speaker body. The high-frequency unit assembly includes a speaker unit and connectors arranged sequentially from the cover to the outer expansion cover. The speaker unit includes an electrode plate and a diaphragm fitted in the electrode plate. A connector is provided on the back of the electrode plate, and the connector extends through a through hole in the cover. The connector has a cutout that matches the contour of the speaker unit. The cover, electrode plate and connector are provided with corresponding connection holes. The cover assembles the speaker unit, connector and fixing post on the back of the outer cover through the connection holes.

[0008] As a further embodiment of this utility model, an assembly groove is formed on the outside of the inner cavity, and the edge of the outer expansion cover is fixed in the assembly groove.

[0009] As a further embodiment of this utility model, a filter cover is provided between the connector and the outer expansion cover, and the filter cover has filter grids corresponding to the hollowed-out position and the shape of the diaphragm.

[0010] As a further embodiment of this utility model, the outer expansion cover has a funnel-shaped structure, the tip of which is a sound outlet, and the sound outlet diffuses outward in an arc shape.

[0011] As a further embodiment of this invention, the fixing post is fixed to the edge of the assembly groove.

[0012] As a further embodiment of this utility model, the connector, the filter cover, and the outer expansion cover are all thermoplastic molded integral plastic shell structures.

[0013] The beneficial effects of this utility model are as follows: This technical solution uses a high-frequency unit assembly consisting of a cover, speaker unit, connectors, and an outer enclosure assembled sequentially. The assembly utilizes connecting holes and fixing posts through each component to achieve multi-sided clamping and fixation, which enhances the structural stability of the diaphragm in the electrode plate. This effectively suppresses the burr noise caused by vibration and loosening under high-power operation. At the same time, the compact packaging design also improves the protection of the unit and the overall heat dissipation efficiency, making the high-frequency output of the speaker clearer and purer, and significantly extending its service life.

[0026] Please see the appendix Figure 1-8 , This technical solution provides a high-frequency amplification structure for a high-power speaker assembly. Its connection structure mainly includes a high-frequency unit assembly (12) disposed on one side of the speaker body (1) and communicating with the inner cavity (10). This assembly, from the inside out, consists of a cover (120), a speaker unit (121), a connector (122), and an outer enclosure (124). The speaker unit (121) includes a pole plate (1210) and a diaphragm (1211) embedded in the pole plate (1210). A connector (1212) is provided on the back of the pole plate (1210), which passes through a through hole (1200) on the cover (120) and connects to the internal circuitry. The connector (122) has a cutout (1220) matching the shape of the speaker unit (121) for accommodating and positioning the speaker unit (121). The cover (120), electrode plate (1210) and connector (122) are all provided with corresponding connection holes (125). Through these connection holes (125), the cover (120) firmly fixes the speaker unit (121) and connector (122) to the fixing post (1240) on the back of the outer cover (124), realizing multi-side clamping assembly.

[0027] More specifically, this solution clamps and fixes the speaker unit (121) from both sides using a cover (120) and connectors (122), enhancing the stability of the diaphragm (1211) and preventing loosening or displacement caused by high-power vibration. The outer cover (124) further encapsulates the entire high-frequency unit assembly (12) within the mounting slot (11) of the speaker body (1), forming a more integrated sound-emitting structure. This not only improves the mechanical strength of the unit and effectively suppresses the generation of high-frequency harsh sounds, but also significantly enhances the reliability and service life of the speaker under continuous high-power operation. The overall structure is reasonable, the assembly is simple, and it has good practicality and stability. Compared with the high-frequency part of traditional high-power speakers, it greatly extends the service life.

[0028] Reference Appendix Figure 2 In a preferred embodiment of this utility model, a mounting groove (11) is provided outside the inner cavity (10) of the speaker body (1). The edge of the outer cover (124) can be directly fixed in the mounting groove (11). After assembly, the outer cover (124) can remain flat and not protrude from the surface of the speaker body (1), resulting in a cleaner appearance.

[0029] Furthermore, the tank structure has a limiting function on all four sides, which restricts the shaking (mainly vibration) of the outer cover (124) during operation, enhances the stability and reliability of the overall structure, and further reduces burr noise.

[0030] Reference Appendix Figure 4In a preferred embodiment of this utility model, a filter cover (123) is provided between the connector (122) and the outer expansion cover (124).

[0031] Specifically, the filter cover (123) is provided with filter grids (1230) that correspond to the shape of the cutout (1220) of the connector (122) and the diaphragm (1211) of the speaker unit (121). The filter cover (123) can fit tightly in the sound path, which can not hinder the propagation of normal high-frequency sound, but effectively filter out the noise and specific noise generated during the vibration process, thereby significantly improving the sound quality, reducing the harsh sound, making the sound output purer and clearer, and also helping to protect the internal speaker unit (121).

[0032] Reference Appendix Figure 7 In a preferred embodiment of this utility model, the outer cover (124) adopts a funnel-shaped structure, with its tip set as a sound outlet (1241), and the sound outlet (1241) diffuses outward in a smooth arc shape. The high-frequency sound generated by the diaphragm (1211) can smoothly enter the funnel-shaped starting end from the hollow part of the connector (122) and be naturally guided outward along the arc-shaped wall to the sound outlet (1241) to propagate outward.

[0033] Understandably, the arc-shaped diffusion structure can effectively guide the direction of sound waves, avoiding sound reflection and resonance within the enclosure. This significantly reduces the sound quality degradation caused by sound wave interference and reflection, resulting in clearer, purer high-frequency sound output and a longer propagation distance.

[0034] Reference Appendix Figure 5 , 2 In a preferred embodiment of this utility model, the fixing post (1240) on the back of the outer expansion cover (124) is fixed at the edge of the assembly groove (11) to prevent displacement or loosening caused by high-power vibration. Optionally, this edge fixing structure also facilitates assembly and maintenance by means of screws or other detachable methods, improving the reliability of the structure and the convenience of use.

[0035] Reference Appendix Figure 4 In a preferred embodiment of this utility model, the connector (122), filter cover (123), and outer expansion cover (124) in this solution are all integral plastic shell structures made by thermoplastic molding process. Each component has a sturdy structure and strong integrity. The connection and cooperation between them are more precise and tight. This not only simplifies the production and assembly process and reduces the manufacturing cost, but also avoids problems such as loosening, vibration and abnormal noise or poor sealing that may be caused by splicing multiple parts. It improves the overall stability, reliability and durability of the high-frequency amplification structure and is suitable for large-scale events such as outdoor performances, parties and speeches.

[0037] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
