Description

Technical Field

[0001] This utility model relates to the field of surface mount buzzer technology, and in particular to an electromagnetic surface mount buzzer. Background Technology

[0002] An electromagnetic surface mount buzzer consists of an oscillator, an electromagnetic coil, a magnet, a diaphragm, and a housing. When the power is turned on, the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the coil to generate a magnetic field. Under the interaction of the electromagnetic coil and the magnet, the diaphragm vibrates periodically to produce sound.

[0003] The existing installation method for electromagnetic surface mount buzzers is as follows: First, the operator connects the electromagnetic surface mount buzzer to an external controller. Then, using tools such as screwdrivers, the electromagnetic surface mount buzzer is fixed in the desired position. When in use, the electromagnetic surface mount buzzer sounds an alarm when it receives a signal.

[0004] Based on the aforementioned technologies, the applicant believes that existing electromagnetic patch buzzers require external tools during installation, making installation, disassembly, replacement, and maintenance of the buzzers inconvenient. To address these issues, we have developed an electromagnetic patch buzzer. Utility Model Content

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] Reference Figure 1 - Figure 5 An electromagnetic patch buzzer includes a mounting base 1, inside which a patch buzzer body 2 is placed. Electromagnetic plates 3 are fixedly connected in a rectangular array on both sides of the patch buzzer body 2. A mounting mechanism is provided on the outer side of the mounting base 1, including mounting frames 41 symmetrically fixedly connected to the outer side of the mounting base 1. Sliding rods 42 are fixedly connected inside each of the two mounting frames 41. Sliding blocks 43 are slidably connected to the outer sides of each of the two sliding rods 42. A fastening spring 44 is fitted onto the outer side of each of the two sliding blocks 43. Rotating plates 45 are rotatably connected to the outer sides of each of the two rotating plates 45, away from the sliding blocks 43. A fixing rod 46 is fixedly connected to the end of each rotating plate 45 away from the sliding blocks 43. Anti-detachment grooves 47 are symmetrically formed on the side of the mounting base 1 near the fixing rod 46, and the anti-detachment grooves 47 and fixing rods 46 cooperate with each other. T-shaped plates 6 are fixedly connected to both sides of the inner wall of the mounting base 1, and T-shaped grooves 5 are symmetrically formed on the outer side of the patch buzzer body 2. The size of the T-slot 5 matches the size of the T-plate 6, and the T-slot 5 and the T-plate 6 are used together.

[0024] In the above technical solution, considering that the existing electromagnetic patch buzzer requires external tools during installation, making it inconvenient to install, disassemble, replace, or repair the buzzer, the specific operation is as follows:

[0025] Reference Figure 1 - Figure 5In a preferred embodiment, the patch buzzer body 2 is slid into the mounting base 1, and the T-shaped plate 6 is aligned with the T-shaped groove 5 for installation. After the patch buzzer body is fully inserted into the mounting base 1, the operator pulls the fixing rod 46 by hand, causing the fixing rod 46 to pull the sliding block 43 to slide on the outside of the sliding rod 42, thereby compressing the fastening spring 44. Then, the rotating plate 45 is rotated, causing the rotating plate 45 to drive the fixing rod 46 to rotate until the fixing rod 46 enters the anti-detachment groove 47. Under the action of the fastening spring 44, the fixing rod 46 can be made more stable. Through the installation mechanism, the patch buzzer body 2 can be quickly installed without the need for external tools, making the installation relatively simple. After installation, it is convenient to disassemble and repair the patch buzzer body 2, improving work efficiency. The structure is simple and highly practical.

[0026] Reference Figure 1 - Figure 5 In a preferred embodiment, anti-detachment hooks 7 are symmetrically fixedly connected to the side of the mounting base 1 near the fixing rod 46. Both sides of the surface-mount buzzer body 2 are provided with sound-emitting areas 8. A heat dissipation window 9 is provided at the bottom of the mounting base 1 for heat dissipation of the surface-mount buzzer body 2. The anti-detachment hooks 7 prevent the fixing rod 46 from suddenly falling off due to pulling, and the heat dissipation window 9 allows for heat dissipation of the surface-mount buzzer body 2, preventing overheating.

[0027] Working principle: In actual use, the operator first installs the mounting base 1 in the desired position, then slides the surface-mount buzzer body 2 into the mounting base 1, aligns the T-shaped plate 6 with the T-shaped groove 5 for installation. After the surface-mount buzzer body is fully inside the mounting base 1, the operator pulls the fixing rod 46 by hand, causing the fixing rod 46 to pull the sliding block 43 to slide on the outside of the sliding rod 42, thereby compressing the fastening spring 44. Then, the rotating plate 45 is rotated, causing the rotating plate 45 to drive the fixing rod 46 to rotate until the fixing rod 46 enters the anti-detachment groove 47. Under the action of the fastening spring 44, the fixing rod 46 can be made more stable. The anti-detachment hook 47 can prevent the fixing rod 46 from falling off after being suddenly pulled.
