[0024] The present invention will be further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 8As shown, the present embodiment provides a speaker and a sound source module thereof which are convenient for directly adjusting the volume, including a speaker housing 1, a sounding part 2 is fixedly installed at one end of the speaker housing 1, a packaging board 3 is fixedly installed at the other end of the speaker housing 1, a control mainboard 4 is plugged into the speaker housing 1, an embedded control chip is built in the mainboard, and dynamic management logic is run. By driving automatic loading and resource allocation technology, seamless switching and efficient tone calling of the sound source module are realized, the control mainboard 4 is fixedly connected to the speaker housing 1 through an embedded fixed connection component 5, a volume knob 6 is rotatably installed on the top of the speaker housing 1, and the volume knob 6 is electrically connected to the control mainboard 4 and the sounding part 2, and the inner wall of the top end of the speaker housing 1 is provided with a volume knob 6. A transverse mounting block 7 is fixedly installed, a limit slot is provided on the transverse mounting block 7, a push pin type positioning component 8 is installed in the limit slot, a follower turntable 9 is fixedly installed at one end of the volume knob 6, one end of the push pin type positioning component 8 is plugged into the follower turntable 9 for positioning the follower turntable 9, a signal shielding plate 10 and a vertical mounting frame 11 are evenly installed on the inner wall of the speaker housing 1, a square limit frame 12 is fixedly installed on the side wall of the signal shielding plate 10, a sound source module body 13 is plugged into the square limit frame 12, and one end of the sound source module body 13 is plugged into the sound source slot provided on the control main board 4, and the sound source module body 13 is evenly plugged into the sound source slot, Used to allocate independent signal channels, the mainboard has a built-in embedded control chip, runs dynamic management logic, and realizes seamless switching and efficient tone calling of the sound source module body 13 by driving automatic loading and resource allocation technology. When in use, each sound source module body 13 allocates an independent signal channel through the dynamic allocation system to avoid resource competition. A converging clamping and stabilizing component 14 is installed on the inner wall of the vertical mounting frame 11. The converging clamping and stabilizing component 14 is used to clamp and position the other end of the sound source module body 13. When in use, the volume is adjusted by rotating the volume knob 6 on the top of the speaker housing 1. The volume knob 6 is electrically connected to the control mainboard 4 to realize the instantaneous volume. When adjusting, after the volume adjustment is completed, the follow-up rotating disk is positioned under the action of pushing the latch-type positioning component 8, which can ensure the stability of the volume knob 6 and avoid misoperation. The sound source module body 13 is stably inserted into the signal shielding plate 10 through the square limit frame 12, and the other end is inserted into the sound source slot of the control main board 4, which is not only convenient for the rapid installation and removal of the sound source module, but also effectively reduces signal interference through the signal shielding plate 10 to ensure clear sound quality.

[0026] The sounding part 2 includes a frame 201, a soft iron 202 and a magnet 203. The frame 201 is fixed on the speaker housing 1. The magnet 203 is fixedly installed at one end of the frame 201. The soft iron 202 is fixedly inserted in the magnet 203. A coil 204 is sleeved on the soft iron 202. The coil 204 is located inside the magnet 203. A vibration membrane 205 is fixedly installed on the frame 201. The sounding part 2 is firmly installed on the speaker housing 1 through the frame 201. When the audio signal is transmitted through the coil 204, due to the constant magnetic field generated by the magnet 203 fixed at one end of the frame 201, the current in the coil 204 will interact with it to generate a changing magnetic field. This changing magnetic field will drive the soft iron 202 to reciprocate, and then drive the coil 204 sleeved thereon to vibrate together. The vibration of the coil 204 is then transmitted to the vibration membrane 205 fixed on the frame 201, and the vibration membrane 205 vibrates accordingly and converts the audio signal into sound waves and releases them to form sound.

[0027] The embedded fixed connection component 5 includes a transverse embedded strip 501 and a plug-in fixing seat 502. The control main board 4 is fixed at the bottom of the transverse embedded strip 501. The transverse embedded strip 501 is plugged into the makeshift hole groove opened at the top of the speaker housing 1. The plug-in fixing seat 502 is fixedly installed on the outer walls of the speaker housing 1 at both ends. Connecting plug blocks 503 are fixedly installed at both ends of the bottom of the transverse embedded strip 501. The connecting plug blocks 503 are plugged into the plug-in fixing seat 502. Corresponding connecting screw holes are opened on the connecting plug blocks 503 and the plug-in fixing seat 502. A fixing screw 504 is threadedly inserted in the connecting screw hole. A screw head 505 is fixedly installed at one end of the fixing screw 504 to firmly fix the control main board 4 at the bottom of the transverse embedded strip 501. Next, align the transverse embedding strip 501 with the clearance hole groove opened on the top of the speaker housing 1 and insert it smoothly into it to ensure that the transverse embedding strip 501 and the speaker housing 1 fit tightly and are accurately positioned. Subsequently, align the connecting blocks 503 at both ends of the bottom of the transverse embedding strip 501 with the plug-in fixing seats 502 fixedly installed on the outer walls of the two ends of the speaker housing 1 and insert them. At this time, the connecting blocks 503 and the corresponding connecting screw holes on the plug-in fixing seats 502 will be completely aligned. Finally, the fixing screw 504 is threaded into the connecting screw hole by means of the screw head 505 until the fixing screw 504 is fully tightened, thereby firmly connecting the transverse embedding strip 501 and the control main board 4 fixed at the bottom thereof to the speaker housing 1, which is not only easy to install but also ensures the stability and reliability of the control main board 4.

[0028] The push-pin type positioning assembly 8 includes a transverse threaded rod 801 and a vertical driving rod 802. The transverse threaded rod 801 is rotatably mounted on the inner wall of one end of the limiting slide groove through a rotating joint 803. A driven bevel gear 804 is fixedly mounted on one end of the transverse threaded rod 801. The vertical driving rod 802 is rotatably plugged into the speaker housing 1. An active bevel gear 805 is fixedly mounted on one end of the vertical driving rod 802, and the active bevel gear 805 is meshed and connected with the driven bevel gear 804. A rotating driving column 806 is fixedly mounted on the other end of the vertical driving rod 802. The rotating driving column 806 is located above the speaker housing 1. A threaded slider 807 is installed on the transverse threaded rod 801. The threaded slider 807 is slidably engaged in the limiting slide groove. An extended connecting plate 808 is fixedly mounted on the threaded slider 807. A positioning pin rod 809 is fixedly mounted on the side wall of the extended connecting plate 808. One end of the positioning pin rod 809 is plugged into The positioning pin holes evenly arranged on the follower turntable 9 are used. When in use, the rotating drive column 806 located above the speaker housing 1 is controlled to drive the vertical drive rod 802 to rotate. Due to the meshing connection between the active bevel gear 805 and the driven bevel gear 804, the rotation of the vertical drive rod 802 will drive the transverse threaded rod 801 to rotate on the inner wall of one end of the limiting slide groove through the rotating joint 803. As the transverse threaded rod 801 rotates, the threaded slider 807 slides and engages in the limiting slide groove and moves along the thread track, thereby driving the extended connecting plate 808 and the positioning pin rod 809 on its side wall to move together. When the positioning pin rod 809 is aligned with the positioning pin holes evenly arranged on the follower turntable 9, the rotation drive is continued until the positioning pin rod 809 is inserted into the positioning pin hole, thereby realizing the positioning of the follower turntable 9 and the volume knob 6, avoiding accidental touching of the volume button and affecting the overall use effect of the speaker.

[0029] The convergent clamping stabilizing assembly 14 includes a bidirectional lead screw 1401, which is rotatably mounted on the inner wall of one end of the vertical mounting frame 11 through a rotating connector 1402, one end of the bidirectional lead screw 1401 is rotatably plugged into the vertical mounting frame 11 and the speaker housing 1, and a vertical rotating handle 1403 is fixedly mounted on one end of the bidirectional lead screw 1401, and the vertical rotating handle 1403 is located above the speaker housing 1, a clamping slider 1404 is threadedly mounted on the bidirectional lead screw 1401, and the clamping slider 1404 is slidably clamped in the vertical mounting frame 11, there are two clamping sliders 1404, the two clamping sliders 1404 are respectively located at the reverse thread ends of the bidirectional lead screw 1401, and an upper clamping positioning head 1405 and a lower clamping positioning head 1406 are respectively mounted on the two clamping sliders 1404, The upper clamping positioning head 1405 and the lower clamping positioning head 1406 are respectively fixedly connected to the two clamping sliders 1404 through the L-shaped connecting frame 1407. When in use, the vertical rotating handle 1403 located above the speaker housing 1 is rotated to drive the two-way lead screw 1401 to rotate on the inner wall of one end of the vertical mounting frame 11 through the rotating connecting head 1402. Since the two-way lead screw 1401 is provided with reverse screw threads, as the two-way lead screw 1401 rotates, the two clamping sliders 1404 will respectively gather toward the center or disperse outward along the vertical mounting frame 11, and the upper clamping positioning head 1405 and the lower clamping positioning head 1406 respectively installed on the two clamping sliders 1404 through the L-shaped connecting frame 1407 will also move accordingly, thereby achieving the clamping or release of the other end of the sound source module body 13. When the sound source module needs to be fixed, just rotate the vertical rotating handle 1403 so that the two clamping positioning heads can tightly clamp the sound source module; when the sound source module needs to be removed or replaced, the clamping can be easily released by rotating the vertical rotating handle 1403 in the opposite direction. It is easy to operate and the clamping is stable and reliable, ensuring the stability and safety of the sound source module.
