Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a flat panel loudspeaker based on improved reliability. Background Technology

[0002] With the development of loudspeakers, flat panel loudspeaker technology emerged. Flat panel loudspeakers aim to achieve breakthroughs in sound quality and reliability by optimizing the speaker's structural design.

[0003] In related technologies, flat panel loudspeakers generally face problems such as small bonding area between voice coil and cone, low flat panel strength, and insufficient overall reliability.

[0004] Specifically, the limited bonding area between the voice coil and the cone of a traditional flat panel loudspeaker results in insufficient connection strength, which in turn affects the overall strength of the flat panel. At the same time, due to the lack of effective support and fixing structure, the voice coil is prone to displacement or collision with other components during vibration, further reducing the reliability of the loudspeaker.

[0005] These issues limit the application scope and performance improvement of flat panel speakers. Utility Model Content

[0006] To address the shortcomings of the existing manufacturing technology, the applicant provides a flat panel loudspeaker based on improved reliability.

[0009] Cone, voice coil, glued bracket, wiring support frame, positioning support plate, magnetic pole core, magnet, frame, terminal block and magnetic conductor plate;

[0010] The diaphragm and voice coil are glued together to form a glued surface, and a glued support is added between the voice coil and the diaphragm to increase the glued surface.

[0017] As a further improvement to the above technical solution:

[0018] In one embodiment, the adhesive support is a ring structure, with its inner diameter matching the outer diameter of the voice coil and its outer diameter matching the inner diameter of the cone. It is firmly bonded to the voice coil and the cone respectively by adhesive to increase the connection strength between the voice coil and the cone and the overall strength of the plate.

[0019] In one embodiment, the wiring support frame is a rigid structure, and the shape of the wiring support frame is adapted to the voice coil wiring portion.

[0020] In one embodiment, the positioning support is an elastic structure with a positioning hole that matches the outer diameter of the voice coil. The voice coil passes through the positioning hole and is connected to the positioning support. The edge of the positioning support is connected to the frame to limit the range of motion of the voice coil in the magnetic field and prevent the voice coil from shifting or colliding with other components.

[0021] In one embodiment, the speaker frame is provided with multiple mounting holes and connecting structures, which are respectively connected to the magnetic pole core, magnet, positioning support plate and terminal block to form a stable speaker structure and withstand the vibration and impact during the operation of the speaker.

[0022] In one embodiment, the shape of the magnetic conductor sheet matches the magnetic pole core and is closely attached around the magnetic pole core to guide and concentrate the magnetic field generated by the magnetic pole core, thereby improving the utilization efficiency of the magnetic field and the working performance of the speaker.

[0023] In one embodiment, the surface of the cone is provided with reinforcing ribs or a textured structure to improve the rigidity and vibration resistance of the cone and reduce the risk of deformation and breakage during operation.

[0024] In one embodiment, the speaker is further provided with a heat dissipation structure; the heat dissipation structure includes heat dissipation holes provided on the frame to accelerate the dissipation of heat generated during speaker operation and prevent the speaker from being damaged due to overheating.

[0025] The beneficial effects of this utility model are as follows:

[0040] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0041] like Figures 1-2 The accompanying drawing shows a schematic diagram of the structure of a flat panel speaker based on reliability improvement in one embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0042] This application provides a flat panel speaker based on improved reliability, including a cone 1, a glued bracket 2, a voice coil 3, a wiring support frame 4, a positioning support plate 5, a magnetic pole core 6, a magnet 7, a frame 8, heat dissipation holes 9, a wiring board 10, and a magnetic conductive plate 11.

[0043] In some embodiments, the cone 1 is a flat plate structure with reinforcing ribs or convex-concave structures (not shown in the figure) on its surface to improve rigidity and vibration resistance; the inner side of the cone 1 is bonded and fixed to the outer diameter end of the adhesive bracket 2 by adhesive.

[0044] Furthermore, the adhesive support 2 is an annular structure, with its inner diameter matching the outer diameter of the voice coil 3, and is firmly bonded to the outer wall of the voice coil 3 by adhesive, thereby forming an enlarged adhesive surface, which significantly enhances the connection strength between the voice coil 3 and the cone 1 and the overall structural stability of the flat panel loudspeaker.

[0045] In some embodiments, the voice coil 3 is located below the cone 1, with terminals extending from its bottom.

[0046] Furthermore, the wiring support frame 4 is a rigid structure, its shape adapted to the wiring terminals of the voice coil 3. It is connected to the wiring terminals of the voice coil 3 by welding or snap-fitting to ensure the stability of audio signal transmission. The wiring support frame 4 is fixed below the voice coil 3 to support the voice coil wiring and prevent wiring breakage or poor contact due to stress concentration during vibration.

[0047] In some embodiments, the positioning support 5 is an elastic metal sheet located below the wiring support frame 4, and its center is provided with a positioning hole that matches the outer diameter of the voice coil 3.

[0048] The voice coil 3 passes through the positioning hole and is connected to the positioning support 5. The edge of the positioning support 5 is fixed to the frame 8 by screws or clips, thereby limiting the axial movement range of the voice coil 3 in the magnetic field and preventing the voice coil 3 from shifting or colliding with components such as the magnetic pole core 6 and the magnet 7.

[0049] In some embodiments, the magnetic pole core 6 and the magnet 7 are coaxially connected to form the magnetic circuit system of the speaker. The frame 8 is a metal frame structure, with its upper part fixed to the magnetic pole core 6 and the magnet 7 through mounting holes, and its lower part connected to the positioning support 5 and the terminal block 10;

[0050] Furthermore, the basin frame 8 is provided with multiple reinforcing ribs and mounting holes to disperse vibration stress and improve the overall structure's impact resistance.

[0051] Furthermore, the magnetic guide sheet 11 has a ring structure and is closely attached to the magnetic pole core 6 to guide and concentrate the magnetic field, thereby improving the magnetic field utilization efficiency and the acoustic performance of the speaker.

[0052] In some embodiments, the side wall of the basket 8 is evenly distributed with a plurality of heat dissipation holes 9 to accelerate the dissipation of heat when the speaker is working, and to avoid aging or damage of components due to excessive temperature rise.

[0053] Furthermore, the junction box 10 is fixed to the bottom of the basket 8, with one end connected to the wiring support frame 4 to transmit audio signals, and the other end extending to the external interface for easy connection to external audio devices.

[0054] The structure of this utility model is reasonable. In actual operation, the voice coil 3 vibrates under the drive of the audio signal, which drives the cone 1 to produce sound. The increased bonding surface of the adhesive bracket 2 and the rigid support structure of the frame 8 jointly suppress vibration deformation. The elastic limit of the positioning support plate 5 and the magnetic field optimization of the magnetic field of the magnetic guide plate 11 can ensure the linearity of the movement of the voice coil 3, thereby improving the sound quality and reliability. At the same time, the design of the heat dissipation hole 9 effectively extends the service life of the speaker.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
