[0027] Reference example Figures 1 to 3, A metal buzzer with waterproof function, including a housing 1 and a circuit board 2 arranged inside the housing 1. The circuit board 2 is provided with a sounding part 21. The circuit board 2 is evenly distributed with a plurality of LED lamp patches 22 with the sounding part 21 as the axis. An outer wall of the sounding part 21 is provided with a sealing ring 3, which is arranged above the LED lamp patches 22 and abuts against the inner wall of the housing 1. An end face of the housing 1 is provided with a sound-transmitting plate 4. A waterproof sound-transmitting film 5 is arranged below the sound-transmitting plate 4. There is a distance for increasing the decibel between the sounding part 21 and the waterproof sound-transmitting film 5. An outer wall and an end face of the housing 1 are provided with a light-emitting part 11. The waterproof sound-transmitting film 5 not only plays a role in sound transmission but also plays a role in waterproofing. The sealing ring 3 prevents the components of the LED lamp patches 22 below the sounding part 21 from getting damp and waterproofing. Through the double-sealing design, the product has an IP65 waterproof rating. By integrating the LED lamp patches 22 on the circuit board 2, the assembly difficulty is greatly reduced and the assembly efficiency is improved. Moreover, by arranging the light-emitting part 11 on the outer wall and the end face of the housing 1, the range of warning the staff is greatly improved;

[0028] It is worth mentioning that the sound-transmitting plate 4 is provided with a plurality of sound-transmitting holes 41, and the sound-transmitting holes 41 enable the sound emitted by the sounding part 21 to be transmitted and diffused;

[0029] It is worth mentioning that the housing 1 is provided with a cavity 12 for accommodating the sound-transmitting plate 4. A sound-transmitting hole 13 is arranged at the bottom of the cavity 12. A conical sound amplifying part 14 is arranged at the sound-emitting place of the sound-transmitting hole 13 and is arranged at the entrance of the sound-transmitting hole 41. The cavity 12 makes the sound-transmitting plate 4 flush with the end face of the housing 1. The sound emitted by the sounding part 21 passes through the waterproof sound-transmitting film 5 and the sound-transmitting hole 13 in sequence, and the sound is diffused through the sound amplifying part 14. Finally, it is transmitted through the sound-transmitting hole 41;

[0030] It is worth mentioning that the waterproof sound-transmitting film 5 is fixed at the entrance of the sound-transmitting hole 13. The material adopted by the waterproof sound-transmitting film 5 usually has excellent waterproof performance and sound-transmitting performance, such as EPTFE (expanded polytetrafluoroethylene) microporous film. This material has tiny pores that can allow sound to pass through while effectively preventing water from entering. When the water vapor is in a small state, it can penetrate smoothly to the other side. However, when the water vapor cools and turns into water droplets, the water molecules cannot penetrate to the other side because the surface tension of the water droplets will hinder the penetration of the water molecules, thus achieving the waterproof effect;

[0031] It is worth mentioning that the outer wall of the housing 1 is provided with a ring 15. The light-emitting part 11 is arranged on the ring 15. The light-emitting part 11 is also arranged on the outer wall of the sound-transmitting plate 4. A metal ring 6 is arranged at the top of the ring 15 and is threadedly connected to the outer wall of the housing 1. The metal ring 6 plays a role in improving the aesthetics of the product. The ring 15 not only plays a role in emitting light but also plays a role in cooperating with the nut on the housing 1 to connect and fix the product to the device;

[0032] It is worth mentioning that the housing 1 is made of a translucent material, and the sealing ring 3 is made of a transparent material. The translucent material of the housing 1 helps the light emitted by the LED lamp patch 22 to conduct to the light-emitting part 11, and the transparent material of the sealing ring 3 helps the light emitted by the LED lamp patch 22 to pass through itself to the light-emitting part 11 on the end face of the housing 1;

[0033] It is worth mentioning that a distance for amplifying the decibel between the sound-emitting part 21 and the waterproof sound-permeable membrane 5 is set to 3.5 mm. By keeping the distance between the sound-emitting part 21 and the waterproof sound-permeable membrane 5 at 3.5 mm, at a distance of 1 meter from this product, the measured decibel value is about 85 decibels, while the measured decibel value of a traditional buzzer at a distance of 1 meter is about 70 decibels. This product effectively increases the decibel compared with the traditional buzzer.

[0034] Through the above design scheme, the product can achieve the advantages of improving the waterproof performance, increasing the decibel, improving the assembly efficiency, and expanding the warning range.

[0035] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
