[0026] See also Figure 1-6 The utility model provides a technical solution: a speaker with waterproof measures, including a speaker body 1. In order to improve the waterproof sealing performance of the speaker body 1, a protective mechanism is arranged outside the speaker body 1. The protective mechanism includes a protective cover 2 and an installation shell 3. In order to facilitate the embedded installation of the speaker body 1, as shown in the attached Figure 3As shown, a mounting cavity 5 is provided inside the mounting shell cover 3, and a mounting groove is provided on the upper opening side of the mounting cavity 5, which is matched with the ring of the speaker body 1, and the bottom side of the ring of the speaker body 1 is embedded and supported on the inner side of the mounting groove. Through the embedding and sealing, the circuit structure of the lower part of the speaker body 1 is completely enclosed in the mounting cavity 5 at the lower part of the mounting shell cover 3 after installation, and will not be affected by external water, thereby greatly improving the waterproof sealing of the speaker circuit. In order to improve the waterproof sealing effect of the ring side of the speaker body 1, a sealing ring gasket is fixed on the bottom side of the ring of the speaker body 1.

[0027] In order to drive the speaker body 1, a signal wiring is installed at the bottom of the speaker body 1. In order to facilitate the insertion and installation of the signal wiring, a wiring through hole 11 is provided at the bottom of the installation shell 3. The wiring through hole 11 is adapted to the signal wiring, and the signal wiring is inserted and installed on the inner side of the wiring through hole 11. In order to improve the waterproof sealing performance of the wiring through hole 11 during installation, the wiring through hole 11 needs to be coated and filled with waterproof sealant.

[0028] In order to facilitate the connection and installation with the protective cover 2, as shown in the attached Figure 3 As shown, a fastening screw 4 is provided on the upper part of the mounting shell cover 3, and a fastening thread is provided on the inner circumference of the lower part of the protective cover 2. The protective cover 2 is threadedly fastened and installed on the upper part of the mounting shell cover 3. In order to compress and limit the speaker body 1, a limiting ring seat is fixed on the inner ring side of the protective cover 2, and the bottom side of the limiting ring seat is pressed against the upper side of the ring of the speaker body 1 to realize the compression and fixation of the speaker body 1.

[0029] In order to facilitate the conduction and diffusion of sound, a sound amplification through hole 9 is provided on the side of the protective cover 2. A plurality of sound amplification through holes 9 are provided. Figure 2 As shown, a plurality of sound amplification holes 9 are evenly opened through the top side of the protective cover 2. In order to improve the waterproofness of the opening side of the protective cover 2, a waterproof partition 6 is arranged in the middle of the protective cover 2. Figure 5 As shown, the waterproof baffle 6 is fixed to the middle of the inner ring of the protective cover 2. In order to block and guide the water, a hemispherical convex seat 7 is arranged on the upper part of the waterproof baffle 6. The hemispherical convex seat 7 is a hemispherical protrusion, and a sound-speaking through hole 8 is arranged in the middle of the hemispherical convex seat 7. Figure 6As shown, a plurality of hemispherical bosses 7 are provided, and several of the hemispherical bosses 7 are evenly fixed on the upper side of the waterproof baffle 6. A sound-speaker through hole 8 is opened through the center of the convex surface of the hemispherical boss 7. While ensuring sound conduction, rainwater entering the protective cover 2 can be blocked and drained, and water can be prevented from directly flowing into the interior of the mounting shell 3. The waterproof effect of the opening side of the protective cover 2 can be effectively improved. In order to discharge the incoming water, a drainage groove 10 is opened through the side of the protective cover 2. The drainage groove 10 is opened on the side of the clamping cavity formed by the waterproof baffle 6. The incoming water can be guided and discharged through the drainage groove 10.

[0030] Working principle or structural principle, during installation, the wiring of the speaker body 1 is passed through the wiring through hole 11 on the bottom side of the mounting shell cover 3, and then the speaker body 1 is embedded and installed in the mounting groove on the upper part of the mounting cavity 5 in the middle of the mounting shell cover 3, so that the sealing ring gasket on the lower side of the ring of the speaker body 1 is tightly attached to the lower groove surface of the mounting groove, and after completion, the protective cover 2 is installed on the upper part of the mounting shell cover 3 by screwing and tightening, and the upper side of the ring of the speaker body 1 is pressed and pressed by the rotation of the protective cover 2 to complete the installation and assembly operation of the speaker body 1. During installation, the device is kept upright, and the speaker is installed inside the device with the drainage notch 10 facing downward;

[0031] During operation, the speaker body 1 receives electrical signals through wiring, and makes the diaphragm vibrate and make sound through the electromagnetic effect. The sound is transmitted and dispersed to the outside through the sound-raising through hole 8 and the sound-amplifying through hole 9, thereby realizing the sound-generating operation. When the speaker body is exposed to rain outside, the rain can be prevented from entering the circuit wiring side of the lower part of the speaker body 1 by installing the shell cover 3 and the protective cover 2 for cooperation and shielding. When rain enters the protective cover 2 from the sound-amplifying through hole 9, the rain entering the protective cover 2 can be blocked and drained by the hemispherical boss 7, thereby preventing the water from directly flowing into the interior of the installed shell cover 3. The blocked rainwater flows down and gathers at the lower part of the waterproof partition 6, and then is discharged to the outside from the drainage groove 10, thereby realizing waterproof protection of the speaker body 1.

[0032] In summary, the present speaker adopts a shell-cover closed installation structure, and the speaker body 1 is installed inside the protective structure formed by the protective cover 2 and the installation shell cover 3 by interlocking. After installation, the circuit structure at the lower part of the speaker body 1 is completely enclosed in the installation cavity 5 at the lower part of the installation shell cover 3 and will not be affected by external water, which greatly improves the waterproof sealing of the speaker circuit. In addition, a double-layer cover structure is adopted, a waterproof baffle 6 is provided at the lower part of the sound amplification through hole 9, and a hemispherical convex seat 7 is provided at the upper part of the waterproof baffle 6, and the sound-raising through hole 8 is provided at the center of the convex surface of the hemispherical convex seat 7. While ensuring sound conduction, the rainwater entering the protective cover 2 can be blocked and drained, and the water can be prevented from directly flowing into the interior of the installation shell cover 3. In conjunction with the drainage groove 10 on the side of the protective cover 2, the incoming water can be diverted and discharged, which can effectively improve the waterproof effect of the opening side of the protective cover 2.
