[0002] With the rapid development of modern communication technology, communication equipment has been widely used in many fields such as emergency rescue, industrial production, and public safety. Traditional communication equipment, such as walkie-talkies and law enforcement recorders, generally suffer from limited functionality and poor expandability. When used in noisy environments, their built-in speakers have limited power, and the sound is easily drowned out by environmental noise, resulting in poor information transmission. In work scenarios where hands need to be freed, the fixing method of the equipment is not flexible enough and cannot meet the diverse needs of users.

[0003] Existing external amplification equipment typically uses wired connections, which are prone to poor contact and limit the range of motion of the equipment. Detachable structures often rely on traditional connection methods such as clips and screws, which are cumbersome to operate and are prone to damage during frequent disassembly, reducing the lifespan of the equipment.

[0004] Therefore, this utility model provides a magnetically amplified and detachable communication device to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a magnetically amplified, detachable communication device, such as... Figures 1 to 4 As shown, the device includes a loudspeaker cone 1, with a conical side connecting portion 101 on the outer arc surface of the loudspeaker cone 1. A loudspeaker ring 2 is fitted onto the lower surface of the loudspeaker cone 1. A buffer portion 201 is provided at the edge of the upper surface of the loudspeaker ring 2. A bowl-shaped end face 202 is provided in the middle of the end face of the loudspeaker ring 2, and the bowl-shaped end face 202 is connected to one end of the buffer portion 201. A bottom portion 203 is provided in the middle of the lower surface of the loudspeaker ring 2, and the top surface of the bottom portion 203 abuts against the bottom of the lower surface of the loudspeaker cone 1. An inwardly turned surface 102 is provided at the bottom of the outer arc surface of the loudspeaker cone 1, and one side of the inwardly turned surface 102 is fitted into the bowl-shaped end face 202. A cover plate 3 is connected to one side of the loudspeaker cone 1. A threaded hole is provided on one side of the cover plate 3. A speaker frame 4 is fixedly installed on one side of the cover plate 3 through the threaded hole. The speaker cone 1 is placed in the middle of the cover plate 3 and the speaker frame 4. A rear housing 5 is connected to one side of the speaker frame 4. A base end 501 is provided in the middle of the inner bottom wall of the rear housing 5. A magnetic block 8 is provided on the upper surface of the base end 501. A stepped end is provided at the top of the inner arc surface of the rear housing 5. A contact member 6 is attached to the inner arc surface of the stepped end of the rear housing 5. An abutment part 601 is provided in the middle of the outer arc surface of the contact member 6. A magnetic ring 7 is snapped onto the lower surface of the abutment part 601. The inner arc surface of the magnetic ring 7 is connected to the magnetic block 8. The upper surface of the contact member 6 is attached to the bottom surface of the speaker frame 4.

[0025] Install the amplifier cone 1. Since the outer arc surface of the amplifier cone 1 has a conical side connecting part 101, it can increase the grip and stability. Slide the amplifier ring 2 onto the lower surface of the amplifier cone 1. At this time, the buffer part 201 at the edge of the upper surface of the amplifier ring 2 fits with the bottom surface of the amplifier cone 1, which plays a role in buffering and shock absorption, reducing the impact of external vibration on the internal structure of the equipment. The bowl-shaped end face 202 is connected to one end of the buffer part 201. The inward turning surface 102 at the bottom of the outer arc surface of the amplifier cone 1 extends into the bowl-shaped end face 202 to achieve a tight fit, ensuring the airtightness of the sound transmission inside and avoiding sound leakage and loss. At the same time, the bottom part 203 in the middle of the lower surface of the amplifier ring 2 abuts against the bottom of the lower surface of the amplifier cone 1, further reinforcing the connection between the two.

[0026] The inner arc surface of the amplification ring 2 has a hollow structure in the middle. The surface buffer part 201 of the amplification ring 2 is in contact with the bottom surface of the amplification cone 1. The inner face 102 of the amplification cone 1 extends into the interior of the amplification frame 4. The outer arc surface of the amplification frame 4 has an amplification cavity 401. The interior of the amplification cavity 401 has a diaphragm 402.

[0027] On one side of the amplifier cone 1, a cover plate 3 with threaded holes is fixed to the amplifier frame 4 with screws, so that the amplifier cone 1 is positioned in the middle of the cover plate 3 and the amplifier frame 4. Next, the rear housing 5 is connected to one side surface of the amplifier frame 4. A magnet 8 is installed on the base end 501 in the middle of the inner bottom wall of the rear housing 5 to provide a foundation for magnetic connection. The inner arc surface of the stepped end at the top of the inner arc surface of the rear housing 5 is fitted with a contact member 6. The lower surface of the abutment part 601 in the middle of the outer arc surface of the contact member 6 is engaged with a magnetic ring 7. The inner arc surface of the magnetic ring 7 is connected to the magnet 8 to achieve magnetic fixation. At the same time, the upper surface of the contact member 6 is fitted with the bottom surface of the amplifier frame 4 to ensure a stable connection between the components and smooth signal transmission. A diaphragm 402 is installed inside the amplification cavity 401 opened on the outer arc surface of the amplifier frame 4. When the communication device receives an audio signal, the signal is transmitted to the diaphragm 402, causing it to vibrate. The vibration is transmitted through the air in the amplification cavity 401. The sound is propagated and amplified internally. The sound is further conducted and diffused through the structure composed of the amplifying cone 1 and the amplifying ring 2. Because the inner arc surface of the amplifying ring 2 has a hollow structure, a sound propagation channel is formed. Combined with the unique conical structure of the amplifying cone 1, this effectively converges and enhances the sound, achieving the amplification function and ensuring clear sound transmission even in noisy environments. When disassembly is required, the magnetic attraction between the magnetic ring 7 and the magnetic block 8 allows for easy and quick separation of the rear housing 5 from the amplifier frame 4 by applying a certain external force to overcome the magnetic force. Disassembly is quick and easy, requiring no tools and causing no damage to the equipment. During reassembly, the magnetic attraction allows for rapid and accurate repositioning of components, ensuring normal operation and meeting users' needs for quick assembly and disassembly and flexible use in different scenarios.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
