Description

Technical Field

[0001] The utility model relates to vehicle-mounted electronic technology, in particular to a waterproof double-horn bicycle buzzer. Background Art

[0002] Buzzers are divided into electromagnetic buzzers and piezoelectric buzzers. Piezoelectric buzzers are widely used in automotive electronics because of their simple structure, economical and durable. Piezoelectric buzzers are mainly driven by a multivibrator to drive a buzzer plate as a sound element. The piezoelectric oscillation plate consists of a piezoelectric ceramic plate with electrodes printed on both sides and a metal plate (brass or stainless steel, etc.). The piezoelectric oscillation plate and the metal plate are bonded together using an adhesive. This is what we commonly call a buzzer plate (i.e., the sound-generating device of the buzzer). When a constant DC voltage is provided externally to provide energy to the multivibrator, the multivibrator starts to vibrate, and a variable voltage and frequency are provided to the piezoelectric ceramic plate. The piezoelectric ceramic plate converts electrical energy into mechanical energy, and the sound is played.

[0003] Since piezoelectric buzzers have integrated circuits inside, they are prone to device failure in water environments. In addition, water can also cause the sound element to be unable to vibrate and make sounds. Usually, buzzers are used in devices, and the buzzer itself has poor waterproof performance. When the buzzer encounters water, it cannot effectively guarantee the normal operation of the buzzer. Utility Model Content

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0019] like Figures 1 to 4 In the embodiment of the waterproof dual-horn bicycle buzzer of the utility model shown, the waterproof dual-horn bicycle buzzer includes a central seat 1, sound-transmitting covers 2 are installed on both sides of the central seat 1, a concave waterproof sound-transmitting membrane 3 is fixedly connected to the inner wall of the sound-transmitting cover 2, a loudspeaker 4 with an enlarged opening is also fixedly connected to the inner wall of the sound-transmitting cover 2, a sound-emitting component is connected to the tail of the loudspeaker 4, and the waterproof sound-transmitting membrane 3, the loudspeaker 2 and the sound-emitting component are symmetrically arranged on both sides of the central seat 1.

[0020] Specifically, after the sound-emitting component is connected to the power supply, a sound is emitted, which is diffused through the loudspeaker 4, passes through the waterproof sound-permeable membrane 3, reaches the sound-permeable cover 2, and diffuses out from the sound-permeable cover 2. The waterproof sound-permeable membrane 3 is made of a high molecular polymer material, has a waterproof and sound-permeable effect, and can prevent external water from entering the interior of the buzzer, thereby avoiding damage and malfunction of the buzzer.

[0021] In one embodiment of the present application, preferably, the sound-generating component includes a resonance box 5 and a buzzer 6, the buzzer 6 is installed at the tail of the resonance box 5, the resonance box 5 is fixedly connected to the tail of the loudspeaker 4, an integrated circuit board 7 is fixedly installed on the center seat 1, the buzzer 6 is electrically connected to the integrated circuit board 7, a multivibrator and an impedance matcher are integrated on the integrated circuit board 7, which are used to generate electric energy harmonics after power is turned on to drive the buzzer 6 to vibrate and make sound, generate resonance and amplification in the resonance box 5, and then cooperate with the loudspeaker 4 and the sound-transparent cover 2 to diffuse the sound.

[0022] In one embodiment of the present application, preferably, the sound-transmitting cover 2 is fixedly connected with raised semi-circular balls 8 arranged in an array, with gaps left between the raised semi-circular balls 8, and a through hole 9 is opened in the center of the raised semi-circular balls 8. When intermittent water droplets are generated from the outside (such as rain), the water droplets will not gather on the sound-transmitting cover 2 nor flow into the buzzer from the through holes 9 on the raised semi-circular balls 8, thereby further ensuring the waterproof performance of the buzzer.

[0023] In one embodiment of the present application, preferably, grooves 10 are provided on both sides of the center seat 1, and the sound-transmitting cover 2 is assembled into the grooves 10 to facilitate the sealing of the joints after assembly.

When the buzzer is installed, the connector between the wire pin 14 and the external power supply and signal line can be sealed in the wiring groove 13 to prevent water from entering the inside of the buzzer from the position of the wire pin 14.

[0026] To sum up, the waterproof dual-horn bicycle buzzer in the above embodiment of the utility model, specifically, after the integrated circuit board 7 is powered on, the buzzer generates electric energy harmonics to drive the buzzer plate 6 to vibrate and sound, which generates resonance and amplification in the resonance box 5, and then cooperates with the loudspeaker 4, diffuses through the waterproof sound-permeable membrane 3 through the loudspeaker 4 to reach the sound-permeable cover 2, and diffuses out from the sound-permeable cover 2. The waterproof sound-permeable membrane 3 is made of a high molecular polymer material and has a waterproof and sound-permeable effect. In addition, by providing the sound-permeable cover 2 with a raised semi-circular sphere 8 to increase the position of the through hole 9 on the sound-permeable cover 2, it is prevented that water can easily enter the buzzer from the position of the through hole 9 on the sound-permeable cover 2, and the wire pin 14 is enclosed in the mounting seat 12 through the hidden wiring groove 13. The device adopts a variety of methods to prevent external water from entering the inside of the buzzer to avoid damage and malfunction of the buzzer.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
