Description

Technical Field

[0001] This utility model relates to the field of buzzer technology, and in particular to a buzzer with waterproof amplification function. Background Technology

[0002] Buzzers are widely used in various fields, including but not limited to: outdoor equipment: intelligent agricultural equipment, outdoor advertising machines, drones; industrial control: PLC control systems, CNC machine tools, automated production lines, instruments and meters, construction machinery; public safety: fire alarms, security systems, access control systems; and special industries: mines, oil fields, ships. Existing buzzers have poor environmental adaptability, low sound volume, and poor alarm effect, and cannot meet the usage conditions of outdoor and industrial applications.

[0003] Therefore, a buzzer with waterproof amplification function is needed to effectively solve this problem. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a buzzer with waterproof amplification function. By designing the matching relationship between the buzzer cap, sealing ring, waterproof sound-permeable membrane, amplifying head, buzzer sound-generating component, and shell, the product meets the waterproof amplification function and is suitable for harsh or special use scenarios. At the same time, it has high reliability and reduces maintenance costs and failure rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A buzzer with waterproof amplification function includes a buzzer sound-generating component and a housing. The housing includes a circuit board stepped surface, internal threads, screw mounting slots, and rectangular holes. The buzzer sound-generating component includes buzzer components, a circuit board, and solder leads. The circuit board and solder leads are installed inside the housing, while the buzzer components are located outside the housing. The amplifier head is installed outside the buzzer components. A buzzer color cap is fitted over the amplifier head and connected to the internal threads of the housing through the external threads of the buzzer color cap. A wiring screw assembly is installed inside the housing through a soldering plate that mates with the screw mounting slot. The solder leads are soldered to the soldering plate of the wiring screw assembly. The wiring cover is installed by snapping it into a rectangular hole located at the other end of the housing using a mounting clip.

[0007] Furthermore, the buzzer cap is provided with a sealing groove, and a sealing ring is installed in the sealing groove. With the engagement of the external thread of the buzzer cap with the internal thread of the outer shell, and the engagement of the sealing groove with the sealing ring, a sealing and waterproof effect is achieved.

[0008] Furthermore, the buzzer cap is also provided with a sound-emitting hole, and a waterproof and sound-permeable membrane is located inside the buzzer cap. An annular adhesive tape is provided on the waterproof and sound-permeable membrane, which is then adhered to the inside of the buzzer cap, covering the sound-emitting hole. This arrangement achieves a sealing and waterproof effect without affecting the sound-emitting effect of the buzzer components.

[0009] Furthermore, the outer wall of the housing is provided with external threads, and the mounting threaded ring is installed by engaging the internal thread of the mounting threaded ring with the external thread of the housing. A mounting washer is installed at the bottom of the external thread of the housing.

[0010] Furthermore, the megaphone head has a conical amplification surface and a circular mounting hole. The buzzer component passes through the circular mounting hole of the megaphone head, and the conical amplification surface of the megaphone head faces the buzzer cap. The mechanical structure of the conical amplification surface is stable, which can effectively control the sound wave diffusion and amplify the sound loudness.

[0011] Furthermore, the wiring cover is provided with a wiring hole for an external power cord to pass through.

[0012] Furthermore, the number of wiring holes is one or two.

[0013] Furthermore, the welding piece is provided with screw holes, and screws are installed in the screw holes; the screws are used to connect external power cords, which are connected through the wiring holes on the wiring cover and connected by the screws and the wiring screw assembly. Since the welding piece on the wiring screw assembly is welded to the welding lead of the buzzer sound-emitting assembly, power is supplied to the buzzer.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) The buzzer with waterproof amplification function has waterproof performance through the matching relationship between the buzzer color cap and the sealing ring, the buzzer color cap and the outer shell, and the buzzer color cap and the waterproof sound-permeable membrane. It can work stably in humid, rainy, dusty environments and even environments that may be splashed or briefly soaked by water, which greatly expands the application scenarios of the buzzer. It can effectively prevent water vapor, dust and corrosive gases from entering the buzzer, avoiding short circuits, oxidation and corrosion of internal circuits and sound-generating elements, thereby significantly improving the reliability and service life of the product. It is suitable for occasions that require frequent cleaning, such as kitchen equipment, medical equipment, food processing machinery, etc. The waterproof feature ensures that it will not be damaged by water ingress during the cleaning process.

[0016] (2) This waterproof amplifying buzzer effectively amplifies the volume and guides the direction of sound propagation through the conical amplification surface design of the amplifying head and the cooperative relationship between the amplifying head and the buzzer's sound-generating components, ensuring that it can be clearly heard even in noisy industrial environments, vast outdoor spaces, or densely populated areas. In critical applications such as safety alarms, fire alarms, and equipment malfunction alerts, a loud sound is key to attracting attention. The amplification function ensures that alarm information is not drowned out by environmental noise, safeguarding life and property. Attached Figure Description
