Embodiment 1

[0047] Such as Figure 1-5 The sound board assembly shown includes a buzzer 1 for outputting sound waves, a buzzer PCB 2 for controlling the sound of the buzzer, and a bracket 3 for installing the buzzer and the buzzer PCB.

[0048] There are at least three brackets 3 , which are evenly distributed on the buzzer PCB 2 , so that each part of the buzzer PCB 2 is evenly fixed on the bracket 3 .

[0049] Such as image 3 The buzzer PCB 2 shown has buzzer soldering feet 4 for soldering the buzzer 1 . The installation surface of the buzzer 1 is used as the bottom surface, the bottom surface of the buzzer 1 has an inserting portion 5 , and the edge of the inserting portion 5 has an inverted L-shaped groove 6 . Such as figure 2 The buzzer shown in is the top surface of the buzzer.

[0050] There are multiple buzzers 1 , which are evenly arranged on the buzzer PCB 2 . The buzzers 1 are inserted into the buzzer PCB 2 through the socket 5 and welded on the buzzer solder pin 4 . Whe...

Abstract

The invention specifically relates to a sound board component. The sound board component comprises a buzzer, a buzzer PCB board and a bracket for installing the buzzer, wherein an installation slot is formed on the bracket, a left side wall structure and a right side wall structure of the installation slot are symmetric to each other, the structure at each of the side wall comprises a protruded mouth part, a PCB board fixing slot and a welding foot holding part from above down; the height and the width of the PCB board fixing slot are respectively greater than the thickness and the width of the edge of the buzzer PCB board; the buzzer PCB board can move left-right and down-up within a certain range in the installation slot, so that the vibration produced by the sounding of the each buzzer is overlapped when each buzzer produces the sound, the entire buzzer PCB board can produce a resonance effect, thereby producing a great sound attack effect by use of small electric quantity.

Description

technical field [0001] In particular the invention relates to an acoustic panel assembly. Background technique [0002] In the process of dealing with general security incidents or sudden terrorist attacks, armed police and public security often need to deter and disperse rioting crowds at close range. Therefore, the sound panel assembly is an important part of the main dispersal function in the current police dispersal shield. In the current security alarm system, most of the buzzer sound is used as the alarm sound output after the alarm is triggered. Therefore, the alarm system also needs a sound board component with strong penetrating power; sound to deter the activities of criminals. Therefore, the sound panel assembly is an important functional part in special equipment in the fields of security, guards, and anti-riot. In order to achieve better dispersing and deterrent effects, it is necessary for the sound panel assembly to output unbearable sound waves with strong ...
