Description

Technical Field

[0001] This utility model relates to the field of teaching and consonant technology, and in particular to a flat panel speaker using an aluminum honeycomb double-surface vibrating sound-generating plate. Background Technology

[0002] Currently, most teaching and conference audio systems on the market still use traditional speakers, with a few using flat panel speakers;

[0003] While traditional speakers offer superior sound quality, their poor directivity and significant sound attenuation result in an unbalanced sound field, causing different sounds to be heard from different locations. Furthermore, traditional speakers are bulky, expensive, and require specific placement locations, making them unsuitable for wall mounting. Flat panel speakers, on the other hand, typically use a vibrating horn as their driver. Because they emit sound from the entire surface, they offer excellent directivity, minimal sound attenuation, high fidelity, and can be made ultra-thin. Therefore, flat panel speakers are less demanding in terms of placement; they can be used anywhere without taking up much space, and the sound quality remains largely consistent regardless of location.

[0004] However, existing flat panel speakers have an uneven response to different frequency bands, resulting in poor overall sound quality. On the other hand, in order to improve the low-frequency response, flat panel speakers usually use corrugated or honeycomb sandwich double-surface cardboard as the sound-emitting surface, which leads to reduced transient response, insufficient sound transparency, poor reproduction, and poor resistance to moisture, mildew, and pressure, limiting the use environment and making them prone to deformation over time. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven response to different frequency bands, poor overall sound quality, reduced transient response, insufficient sound transparency, poor sound reproduction, poor resistance to moisture, mildew, and pressure, limited use environment, and easy deformation over time. The invention proposes a flat panel speaker using an aluminum honeycomb double-surface vibration sound-generating plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flat panel speaker using an aluminum honeycomb double-surface vibration sound-generating plate includes a speaker body. The speaker body includes a flat panel speaker frame and an aluminum honeycomb double-surface vibration sound-generating plate and a speaker back plate respectively disposed on both sides inside the flat panel speaker frame. A driver is installed on one side of the aluminum honeycomb double-surface vibration sound-generating plate inside the flat panel speaker frame. The aluminum honeycomb double-surface vibration sound-generating plate is composed of two skins and an aluminum honeycomb structure disposed between the two skins.

[0008] The mounting mechanism is used to fix the flat panel speaker frame. The fixing mechanism is set on one side of the speaker back panel. The mounting cabinet includes a base. Sliding frames are fixedly set at both ends of one side of the speaker back panel. A sliding rod is fixedly set at the top of the base. The sliding rod is slidably set in the two sliding frames. Multiple suction cups are fixedly set at the bottom of the base. A hanging groove is opened at the center of the bottom of the base.

[0009] In one possible design, the interior of the flat speaker frame has a second inner cavity, and a second inner plate is slidably disposed inside the second inner cavity. A plurality of second insert rods are fixedly disposed on one side of the second inner plate, and a plurality of second slots are disposed on one side of the speaker back panel. One end of each of the plurality of second insert rods slides through the flat speaker frame, and one end of each of the plurality of second insert rods respectively engages with a plurality of second slots.

[0010] In one possible design, multiple second-position limiting rods are fixedly installed inside the second inner cavity. The second inner plate is slidably sleeved on the outer wall of the second-position limiting rods. A compression spring is sleeved on the outer wall of the second-position limiting rods. The two ends of the compression spring are respectively fixedly installed on one side of the second inner plate and one side of the inner wall of the second inner cavity. A second sliding plate is fixedly installed on one side of the second inner plate. One end of the second sliding plate slides through to the outside of the flat panel speaker frame.

[0011] In one possible design, the mounting mechanism further includes two No. 1 insert rods. The base has a No. 1 inner cavity, and a No. 1 inner plate is slidably disposed inside the No. 1 inner cavity. The two No. 1 insert rods are respectively fixedly disposed on both sides of the top of the No. 1 inner plate. A No. 1 lower slot is provided at the bottom of the sliding frame. The tops of the two No. 1 insert rods slide through to the outside of the base, and the tops of the No. 1 insert rods cooperate with the No. 1 lower slot on the same side. A No. 1 upper slot is provided at the top of one side of the sliding frame, and the tops of the No. 1 insert rods cooperate with the No. 1 upper slot on the same side.

[0012] In one possible design, multiple limiting rods are fixedly installed inside the first inner cavity. The first inner plate is slidably sleeved on the outer wall of the first limiting rod. A tension spring is sleeved on the outer wall of the first limiting rod. The two ends of the tension spring are respectively fixedly installed on the top inner wall of the first inner cavity and the top of the first inner plate. A sliding plate is fixedly installed on one side of the first inner plate. One end of the sliding plate slides through to the outside of the base.

[0013] In one possible design, the fixing mechanism further includes two fixing rods. Connecting plates are fixedly installed at the top and bottom of one side of the second inner plate, and one end of the connecting plate slides through to the outside of the flat speaker frame. The two fixing rods are respectively fixedly installed at one end of the two connecting plates. A fixing groove is opened at one end of the sliding rod, and both connecting plates cooperate with the fixing groove.

[0014] In this application, during actual use, the speaker can be attached to the tabletop using the suction cup at the bottom, ensuring its stability. If wall mounting is required, simply install hooks on the wall, then move the first sliding plate downwards. The first sliding plate moves the first inner plate downwards, which in turn moves the first insert rod, disengaging it from the first lower slot. At this point, the base is disconnected from the sliding frame. Then, move the second sliding plate, which moves the second inner plate. The second inner plate, through the connecting plate, moves the fixing rod, disengaging one end of the fixing rod from the fixing groove, thus releasing the sliding rod. The connection between the base and the speaker frame is completely released from the fixation of the base. Then, simply rotate the base 90 degrees and move it upwards. When the base moves to the top of the side of the speaker back panel, the No. 1 inner plate is reset by the force of the tension spring, which in turn drives the No. 1 plug rod to reset, so that one end of the No. 1 plug rod is locked into the inside of the No. 1 upper slot. The No. 2 inner plate is reset by the force of the compression spring, so that one end of the fixing rod is locked into the inside of the fixing groove. This realizes the adjustment and fixation of the base. Then, it can be hung on the hook through the hanging slot. The suction cup can also be attached to the wall to increase stability.

[0015] When it is necessary to disassemble the speaker back panel to repair or replace the internal driver, simply move the second sliding plate. The second sliding plate moves the second inner plate, which in turn moves the second insertion rod to disengage it from the second slot. This releases the fixation between the flat panel speaker frame and the speaker back panel, allowing for disassembly.

[0016] In this utility model, a flat panel speaker using an aluminum honeycomb double-surface vibrating sound-generating plate can achieve a transparent and pure sound effect, especially making the human voice cleaner and more natural. The metal core plus the special honeycomb structure has strong pressure resistance, can effectively prevent deformation, and is moisture-proof and mildew-proof.

[0017] In this utility model, the flat panel speaker with aluminum honeycomb double-surface vibration sound-generating plate can be stably placed on a table or hung on a wall through a fixing mechanism, thereby avoiding the relatively simple placement method of traditional speakers, which are easily knocked over or fallen, thus causing unnecessary losses.

[0018] In this invention, an aluminum honeycomb double-surface vibration sound-generating plate replaces the existing paper core panel, thereby extending the mid-to-high frequency range of the speaker and producing a clear and pure sound effect. It has strong pressure resistance, effectively prevents deformation, and is moisture-proof and mildew-proof. At the same time, the fixed mechanism ensures that the speaker is placed stably, minimizing the possibility of it being knocked over or falling. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1-3A flat panel speaker includes: a speaker body comprising a flat panel speaker frame 1 and aluminum honeycomb double-surface vibration sound-generating plates 2 and a speaker back plate 6 respectively disposed on both sides inside the flat panel speaker frame 1. The aluminum honeycomb double-surface vibration sound-generating plates 2 can be fixed by existing adhesives or other methods. A driver 29 is installed on one side of the aluminum honeycomb double-surface vibration sound-generating plate 2 inside the flat panel speaker frame 1, and the driver 29 is used to drive the aluminum honeycomb double-surface vibration sound-generating plate 2 to vibrate and generate sound. The aluminum honeycomb double-surface vibration sound-generating plate 2 consists of two skins 4 and an aluminum honeycomb structure 5 disposed between the two skins 4. The aluminum honeycomb structure 5 has good strength and lightweight characteristics, which makes the aluminum honeycomb double-surface vibration sound-generating plate 2 have excellent sound performance and durability.

[0029] Specifically, the aluminum honeycomb double-surface vibration sound-generating board 2 replaces the existing paper sandwich panel. The aluminum honeycomb double-surface vibration sound-generating board 2 uses a metallic aluminum honeycomb as the sandwich layer and is composited with special paper / PET / carbon fiber / glass fiber, etc., as the outer skin material, forming a unique sound-generating material. This extends the mid-to-high frequency range of the speaker, producing a transparent and pure sound effect, especially making the human voice cleaner and more natural. The metal core combined with the special honeycomb structure has strong compressive strength, effectively preventing deformation, moisture, and mold.

[0030] Reference Figure 3 , Figure 5 The flat-panel speaker frame 1 has a second inner cavity 23, and a second inner plate 24 is slidably disposed inside the second inner cavity 23. Multiple second-order inserts 20 are fixedly disposed on one side of the second inner plate 24, and multiple second-order slots 25 are disposed on one side of the speaker back panel 6. One end of each of the multiple second-order inserts 20 slides through the flat-panel speaker frame 1, and one end of each of the multiple second-order inserts 20 engages with one of the multiple second-order slots 25. Through the engagement of the second-order inserts 20 and the second-order slots 25, the speaker back panel 6 can be fixedly connected to the flat-panel speaker frame 1.

[0031] Multiple second-position limiting rods 22 are fixedly installed inside the second inner cavity 23. The second inner plate 24 is slidably sleeved on the outer wall of the second-position limiting rods 22, and a compression spring 21 is sleeved on the outer wall of the second-position limiting rods 22. The two ends of the compression spring 21 are respectively fixedly installed on one side of the second inner plate 24 and one side of the inner wall of the second inner cavity 23. Through the elastic force of the compression spring 21, the second insertion rod 20 can be better inserted into the second slot 25, improving the stability of the connection. A second sliding plate 13 is fixedly installed on one side of the second inner plate 24. One end of the second sliding plate 13 slides through to the outside of the flat panel speaker frame 1. By sliding the second sliding plate 13, the second inner plate 24 can be slid.

[0032] Specifically, when it is necessary to disassemble the speaker back panel 6 to repair or replace the internal driver 29, simply move the second sliding plate 13. The second sliding plate 13 moves the second inner plate 24, and the second inner plate 24 moves the second insertion rod 20 out of the second slot 25, thereby releasing the fixation between the flat speaker frame 1 and the speaker back panel 6, and thus disassembling it.

[0033] This application can be used in the field of consonants in teaching conferences, or in other fields applicable to this application.

[0034] Example 2

[0035] refer to Figure 3 An improvement upon Example 1: A flat panel speaker employing an aluminum honeycomb double-surface vibrating sound-generating plate, applied to the field of auxiliary sound in teaching and conferences. An installation mechanism is used to fix the flat panel speaker frame 1, and the fixing mechanism is located on one side of the speaker back panel 6. The installation mechanism includes a base 3, with sliding frames 7 fixedly installed at both ends of one side of the speaker back panel 6. A sliding rod 9 is fixedly installed on the top of the base 3, slidingly positioned within the two sliding frames 7. Multiple suction cups 11 are fixedly installed on the bottom of the base 3, allowing the base 3 to be adhered to a flat surface for speaker fixation. A hanging groove 12 is provided at the center of the bottom of the base 3 for suspending the speaker, facilitating use in various situations.

[0036] Reference Figure 3-4 The mounting mechanism also includes two primary insertion rods 15. An inner cavity 17 is formed inside the base 3, and an inner plate 16 is slidably disposed inside the inner cavity 17. The two primary insertion rods 15 are fixedly disposed on both sides of the top of the inner plate 16. A lower slot 14 is formed at the bottom of the sliding frame 7. The top ends of both primary insertion rods 15 slide through to the outside of the base 3, and the top ends of the primary insertion rods 15 engage with the lower slot 14 on the same side. An upper slot 8 is formed at the top of one side of the sliding frame 7, and the top ends of the primary insertion rods 15 engage with the upper slot 8 on the same side. Through the engagement of the primary insertion rods 15 with the lower slot 14 and the upper slot 8, the sliding frame 7 and the base 3 can be fixedly connected.

[0037] Multiple limiting rods 18 are fixedly installed inside the first inner cavity 17. The first inner plate 16 is slidably sleeved on the outer wall of the first limiting rods 18, and a tension spring 19 is sleeved on the outer wall of the first limiting rods 18. The two ends of the tension spring 19 are respectively fixedly installed on the top inner wall of the first inner cavity 17 and the top of the first inner plate 16. Through the elastic force of the tension spring 19, the first insertion rod 15 can be better inserted into the first lower slot 14 and the first upper slot 8, improving the stability of the connection. A sliding plate 10 is fixedly installed on one side of the first inner plate 16. One end of the sliding plate 10 slides through to the outside of the base 3. By sliding the sliding plate 10, the first inner plate 16 can be slid.

[0038] Reference Figure 6 The fixing mechanism also includes two fixing rods 26. Connecting plates 27 are fixedly installed on the top and bottom of one side of the inner plate 24, and one end of the connecting plate 27 slides through to the outside of the flat speaker frame 1. The two fixing rods 26 are respectively fixedly installed on one end of the two connecting plates 27. One end of the slide rod 9 is provided with a fixing groove 28, and both connecting plates 27 cooperate with the fixing groove 28.

[0039] Specifically, the speaker can be attached to the tabletop using the bottom suction cup 11, ensuring its stability. For wall mounting, simply install hooks on the wall, then move the first sliding plate 10 downwards. The first sliding plate 10 moves the first inner plate 16 downwards, which in turn moves the first insertion rod 15, disengaging it from the first lower slot 14. At this point, the base 3 will disengage from the sliding frame 7. Then, move the second sliding plate 13, which moves the second inner plate 24. The second inner plate 24, through the connecting plate 27, moves the fixing rod 26, causing one end of the fixing rod 26 to disengage from the fixing groove 28, thus releasing the sliding rod 9 and... The connection between the flat speaker frame 1 completely releases the base 3 from its fixation. Then, simply rotate the base 3 ninety degrees and move it upwards. When the base 3 moves to the top of the side of the speaker back panel 6, the first inner plate 16 is reset by the force of the tension spring 19, which in turn drives the first insertion rod 15 to reset, so that one end of the first insertion rod 15 is locked into the first upper slot 8. The second inner plate 24 is reset by the force of the compression spring 21, so that one end of the fixing rod 26 is locked back into the fixing groove 28, thereby realizing the adjustment and fixation of the base 3. Then, it can be hung on the hook through the hanging groove 12, and the suction cup 11 can also be attached to the wall to increase stability.
