Description

Technical Field

[0001] This utility model relates to the field of speaker module technology, specifically a speaker module with a built-in speaker cavity. Background Technology

[0002] There are several different types of musical instruments. One type is a wind instrument, narrow at the top and wide at the bottom, mostly made of brass. Another type is a modern electroacoustic component, which converts electrical signals into sound; it's also called a loudspeaker. The term can also be used to describe someone who promotes or advocates for others. A loudspeaker is essentially a device that converts electrical energy into sound. When different amounts of electronic energy are transmitted to the coil, the coil generates energy that interacts with the magnetic field of the magnet. This interaction causes the diaphragm to vibrate. Because the electronic energy changes constantly, the loudspeaker's coil moves forward or backward, causing the diaphragm to move accordingly. These movements change the density of the air, producing sound. Currently, loudspeaker modules with built-in speaker chambers, due to their integrated design, are susceptible to sound quality issues if dust accumulates inside the chamber. Utility Model Content

[0003] The purpose of this invention is to provide a speaker module with a built-in speaker cavity, which solves the problem that the sound quality of current speaker modules with built-in speaker cavities is easily affected by dust inside the cavity due to their integrated design.

[0006] Furthermore, a combination groove is provided at the bottom of the acoustic cavity frame, and a combination rod is inserted into the inside of the combination groove. The bottom end of the combination rod is fixedly connected to the upper surface of the sealing plate.

[0007] Furthermore, a rubber sealing ring is fixedly connected to the upper surface of the sealing plate, and the outer surface of the rubber sealing ring overlaps with the inner wall of the sound cavity frame.

[0008] Furthermore, the front of the connecting plate has a handle hole that communicates with the back.

[0009] This utility model provides a speaker module with a built-in speaker cavity. It has the following beneficial effects:

[0010] The speaker module with a built-in speaker cavity, through the cooperation of fixing slots, fixing blocks, combination slots, combination rods, handle holes, connecting plates, springs, slots, balance slots and balance rods, can open the sealing plate to clean the dust inside the speaker cavity frame. This solves the problem that the sound quality of current speaker modules with built-in speaker cavities is easily affected by dust inside the cavity due to the integrated design.

[0013] The components include: 1. Speaker module body; 2. Sound cavity frame; 3. Sealing plate; 4. Rubber sealing ring; 5. Fixing groove; 6. Fixing block; 7. Combination groove; 8. Combination rod; 9. Handle hole; 10. Connecting plate; 11. Spring; 12. Slot; 13. Balance groove; and 14. Balance rod. Detailed Implementation

[0014] like Figure 1-2 As shown, this utility model embodiment provides a speaker module with a built-in speaker cavity, including a speaker module body 1. A cavity frame 2 is fixedly connected to the bottom of the speaker module body 1. A sealing plate 3 overlaps the bottom of the cavity frame 2. A combination groove 7 is opened at the bottom of the cavity frame 2. A combination rod 8 is inserted into the combination groove 7. The bottom end of the combination rod 8 is fixedly connected to the upper surface of the sealing plate 3. A rubber sealing ring 4 is fixedly connected to the upper surface of the sealing plate 3. The outer surface of the rubber sealing ring 4 overlaps the inner wall of the cavity frame 2. A connecting plate 10 overlaps the left side of the sealing plate 3. A connection plate 10 is opened on the front side of the connecting plate 10. The handle hole 9 is connected to the back. A fixing block 6 is fixedly connected to the right side of the connecting plate 10. A fixing groove 5 is opened on the left side of the sound cavity frame 2. The surface of the fixing block 6 is engaged with the inside of the fixing groove 5. A slot 12 is opened on the left side of the sealing plate 3. A balance groove 13 is opened on the inner wall of the slot 12. A balance rod 14 is movably connected inside the balance groove 13. The left end of the balance rod 14 is fixedly connected to the right side of the connecting plate 10. A spring 11 is sleeved on the surface of the balance rod 14. The left end of the spring 11 is fixedly connected to the right side of the connecting plate 10. The right end of the spring 11 is fixedly connected to the right inner wall of the slot 12.

[0015] Working principle: Insert your hand into the handle hole 9 and pull it outwards to disengage the fixing block 6 from the fixing groove 5. Then pull the sealing plate 3 downwards. The sealing plate 3 will cause the combination rod 8 to disengage from the combination groove 7, thereby opening the sealing plate 3. At this time, the inside of the sound cavity frame 2 can be cleaned. After cleaning, put the sealing plate 3 back in its original position so that the combination rod 8 is locked back into the combination groove 7. Then release the handle hole 9. At this time, the spring 11 will contract and drive the connecting plate 10 to reset. The connecting plate 10 will drive the fixing block 6 to lock back into the fixing groove 5 to fix the sealing plate 3.
