Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to lavalier loudspeakers. Background Technology

[0002] In the field of modern communication and public speaking, lavalier megaphones, as a lightweight and efficient audio transmission device, have been widely used in various occasions such as education, meetings, speeches, and tour guide explanations. Their original design intention was to provide users with a hands-free, freely movable, and high-quality sound transmission. However, with the diversification of usage scenarios and the continuous improvement of user needs, some shortcomings in the structural design of existing lavalier megaphones have been exposed. In actual use, many users have reported that due to insufficient friction between the megaphone body and clothing, as well as dynamic changes during human movement, the megaphone is prone to shifting or falling off, affecting normal use. Secondly, most existing lavalier megaphones use pluggable microphone interfaces. Although this design facilitates quick microphone replacement, the interface is prone to loosening after prolonged use or frequent plugging and unplugging, leading to decreased sound pickup quality and even noise. At the same time, existing lavalier megaphones generally use built-in battery designs, requiring frequent charging, which not only inconveniences users but also limits the application range of the megaphone. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Example 1 Reference Figures 1-6 This utility model provides a technical solution: a lavalier megaphone, including a megaphone body 1 and a charging compartment 2. A removable battery 3 is installed inside the lower part of the megaphone body 1, and a charging port 4 is provided at the bottom of the megaphone body 1. The charging compartment 2 is provided with two sets of placement slots 5 that match the megaphone body 1, and a magnetic charging block 6 that matches the charging port 4 is installed inside the placement slots 5. A sound amplification connection mechanism is provided on the side of one end of the megaphone body 1.

[0023] Reference Figure 4 , Figure 5The speaker body 1 has a mounting groove 11 inside that matches the battery 3. The mounting groove 11 has a sliding groove 12 inside its side end. The sliding groove 12 has a matching cover plate 13 inside it, which is slidably engaged. The cover plate 13 has a pull groove 24 on its outer side. The charging port 4 is connected to the battery 3 through an adapter.

[0024] Reference Figure 2 , Figure 3 The amplification connection mechanism includes a speaker 14, a sound-collecting hole 15, a switch button 16, a volume adjustment button 17, an audio interface 18, a threaded hole 19, a microphone 20, a wiring block 21, an external thread 22, and a flexible clamp 23. The speaker 14 is located on the lower side of the amplifier body 1, and the sound-collecting hole 15 is located above the speaker 14. The switch button 16 and the volume adjustment button 17 are located above the sound-collecting hole 15. The sound-collecting hole 15, the switch button 16, and the volume adjustment button 17 are all located on the side of the amplifier body 1. The top of the amplifier body 1 has a threaded hole 19, and the audio interface 18 is located inside the threaded hole 19. The microphone 20 is located on the outside of the amplifier body 1, and the wiring terminal of the microphone 20 is connected to the wiring block 21. The wiring block 21 has an external thread 22 that matches the threaded hole 19 for a movable connection. The threaded connection effectively avoids wear on the interface caused by plugging and unplugging, which would affect the sound reception quality. The flexible clamp 23 is fixedly connected to the outside of the microphone 20 to facilitate the snap-fit ​​of the microphone 20.

[0025] In practical implementation, when using a lavalier megaphone, firstly, the connector 21 is inserted into the audio interface 18. Because the outer side of the connector 21 is provided with an external thread 22 that matches the threaded hole 19, it is movably connected. Manually rotating the connector 21 makes the outer external thread 22 of the connector 21 and the threaded hole 19 tightly and securely connected together, increasing the connection's firmness and preventing the interface from loosening. Next, by pressing the switch button 16, the megaphone body 1 can be started. Pressing the volume adjustment button 17 can adjust the volume of the speaker 14. The microphone 20 is fixedly connected to an elastic clip 23, which makes it easy to clip the microphone 20 onto the lavalier, ensuring the quality of sound pickup. At the same time, the setting of the microphone 20 and the sound acquisition hole 15 realizes the function of collecting sound and amplifying it. In addition, when the amplifier body 1 is low on power, first slide the cover plate 13 upwards through the pull groove 24, so that the cover plate 13 moves inside the slide groove 12, and the battery 3 inside the fixing groove 11 can be taken out and replaced with a fully charged battery 3. Slide the cover plate 13 so that the cover plate 13 slides and engages with the lower part inside the slide groove 12, so that the battery 3 can be replaced. Alternatively, the amplifier body 1 can be placed directly in the charging compartment 2 placement slot 5. Since the placement slot 5 is equipped with a magnetic charging block 6 that matches the charging port 4, the charging port 4 at the bottom of the amplifier body 1 is magnetically connected to the magnetic charging block 6 inside the placement slot 5. The battery 3 is then charged through the adapter (not shown in the figure). Through the above operations, it is ensured that the user can charge the amplifier body 1 at any time in different scenarios, avoiding the impact of insufficient power on use, and significantly improving the overall user experience.

[0026] Example 2 Reference Figure 6 This embodiment is an optimization based on the first embodiment. A clamping mechanism is provided on the side of the other end of the amplifier body 1. The clamping mechanism includes an elastic clip 7, a clamping plate 8, a hinge seat 9, and a rotating shaft 10. The hinge seat 9 is fixedly installed on the side of the amplifier body 1. The clamping plate 8 is installed inside the hinge seat 9 through the rotating shaft 10. The elastic clip 7 is fixedly connected to both sides of the clamping plate 8 at the side end of the amplifier body 1.

[0027] Reference Figure 1 , Figure 3 The clamping mechanism also includes a mounting base 25, a spring 26, and a rubber pad 27. The mounting base 25 is provided on the inner side of one end of the clamping plate 8, and the spring 26 is installed inside the mounting base 25. The elastic clamping piece 7 at the other end and the inner side of the clamping plate 8 are both provided with rubber pads 27.

[0028] In practice, when clamping a lapel-style megaphone, the megaphone body 1 is initially secured to the lapel clip via the elastic clip 7. Since the megaphone body 1 has a hinge seat 9 fixedly mounted on its side, pressing the clip plate 8 causes it to rotate outside the hinge seat 9 via the pivot 10. Simultaneously, the spring 26 inside the mounting base 25 on the inner side of the clip plate 8 is compressed and deformed. Then, the clip plate 8 is manually pressed to adjust the position of the megaphone body 1 on the lapel clip. After adjusting to a suitable position, the clip plate 8 is released. Under the elastic action of the compressed and deformed spring 26, the clip plate 8 is quickly supported, firmly clamping it to the lapel clip and ensuring stability. Furthermore, since both the elastic clip 7 and the inner side of the clip plate 8 are equipped with rubber pads 27, these pads increase the friction between the megaphone and the clothing, ensuring stability under various activity conditions. Thus, through the above operations, the stability of the megaphone body 1 when worn is improved.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
