Description

Technical Field

[0001] This invention relates to the field of speaker technology, and more specifically, to a sound-emitting speaker made of sheet metal. Background Technology

[0002] Traditional panel-based speaker enclosures include a speaker housing, a soundboard, a small driver (tweeter driver), a large driver (midrange driver), a bass reflex port (a structure used to enhance bass performance, located at the rear or bottom of the speaker housing), connectors and cables (used to connect the audio source device to the speaker; the connector is located at the bottom of the speaker housing), and a partition (installed inside the speaker housing to enhance the structural strength and vibration resistance of the speaker). In use, the soundboard is directly attached to the target panel using 3M double-sided tape, thus installing the speaker. No crossover is required; the sound can penetrate the target panel and produce sound simply by attaching the soundboard directly to the front of the panel.

[0003] Traditional panel-based speaker cabinets have a flat, square-shaped shell with an open front. The soundboard is located in the open part of the shell, and the small and large drivers are installed inside the shell and directly fixed to it. Both the small and large drivers are attached to the soundboard with 3M double-sided tape. The soundboard is attached to the open part of the shell with rectangular 3M double-sided tape, and the assembly edges of the soundboard and the shell are completely sealed.

[0004] Traditional board-based speaker enclosures have drawbacks: because the small and large drivers are directly fixed to the enclosure housing, and the assembly edges of the soundboard and the enclosure housing are completely sealed, the vibration amplitude of the sound-producing device is small, resulting in poor bass response. Summary of the Invention

[0005] The present invention provides a sound-generating box made of sheet metal, which can solve the above-mentioned problems.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] A sound-emitting enclosure made of sheet metal includes a speaker housing, a large driver, a small driver, and a sound-emitting board. The speaker housing has a flat box structure with an open front, and the sound-emitting board is covered by a first 3M double-sided adhesive. The small driver and the large driver are installed inside the speaker housing and are both attached to the sound-emitting board by a second 3M double-sided adhesive. The first 3M double-sided adhesive consists of two pieces: a first U-shaped 3M double-sided adhesive and a second U-shaped 3M double-sided adhesive, which are arranged facing each other, creating a gap at the middle of the assembly edge of the sound-emitting board and the speaker housing. The large driver is clearance-fitted to the speaker housing and connected to the speaker housing by an elastic structural component.

[0008] In a preferred embodiment of the present invention, the speaker housing is a square box structure, and the sound-producing plate is a square honeycomb plate that matches the speaker housing.

[0009] In a preferred embodiment of the present invention, the small driver is clearance-fitted with the speaker housing and is connected to the speaker housing via a first rivet assembly.

[0010] In a preferred embodiment of the present invention, the elastic structural component includes an elastic steel sheet and a second rivet assembly, the second rivet assembly connecting the elastic steel sheet and the speaker housing, and the large driver being bolted to the elastic steel sheet.

[0011] In a preferred embodiment of the present invention, the elastic steel sheet includes an annular portion and a plurality of support portions connected to the annular portion; the support portions are connected to the second rivet assembly, and the large actuator is bolted to the annular portion.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The soundboard is attached to the speaker housing by using a first U-shaped 3M double-sided adhesive and a second U-shaped 3M double-sided adhesive. This is equivalent to removing the middle section of the existing rectangular 3M double-sided adhesive, creating a gap in the middle section between the soundboard and the speaker housing. With the assistance of the elastic structural components, the middle section of the soundboard and the large driver form a whole. After the soundboard is attached to the target material, the vibration amplitude of the target material inside and outside is increased, thereby improving the low-frequency sound effect.

[0014] The gap formed at the middle of the assembly edge of the soundboard and the speaker housing allows vibrations to be transmitted better, enhancing the performance of low-frequency sound effects;

[0015] By introducing elastic structural components, including elastic steel sheets and a second rivet assembly, a flexible connection is achieved between the large driver and the speaker housing. This connection method improves the speaker's vibration response and increases the power and texture of low-frequency sound.

[0016] In summary, this invention achieves better sound effects and vibration performance, especially in low-frequency sound effects, by improving the design and installation method of the sound box made of wood panels. This design is suitable for concealed installation within decorative wall panels and can be widely used in audio systems, home theaters, entertainment venues and other fields.
