Description

Technical Field

[0001] The utility model relates to the technical field of buzzer sound amplification, in particular to a novel buzzer sound amplification structure. Background Art

[0002] A buzzer is an integrated electronic sounder powered by direct current voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic devices, telephones, timers, etc.

[0003] At present, ticket printers on the market generally include a housing and a PCB circuit board, and most of the buzzers on the ticket printers are soldered to the bottom PCB board, which is not conducive to the diffusion of sound, resulting in a relatively small sound emitted by the buzzer and unable to play a good reminder role in places such as kitchens, and thus the staff cannot receive it when issuing tickets.

[0004] In view of this, the inventor has specifically designed a novel buzzer sound amplification structure, and this case is thus generated. Summary of the Utility Model

[0005] In order to solve the above problems, the technical solution of the utility model is as follows:

[0006] A novel buzzer sound amplification structure, comprising:

[0007] A housing, on the upper and lower sides of which there are respectively formed a mounting surface and a use surface for mounting a PCB board;

[0008] Mounting posts, standing on the mounting surface of the housing, and an installation cavity with an upper end opening is formed inside;

[0009] A support base, standing in the installation cavity, and a sound amplification channel is formed inside it, which runs through from the top to the use surface of the housing along the inner side;

[0010] A buzzer, arranged inside the installation cavity and on the top of the support base, and its sounding surface faces the sound amplification channel;

[0011] Wherein, the buzzer is connected to the PCB board by wires.

[0012] Preferably, the support base is integrally in the shape of a horn with an open bottom.

[0013] Preferably, the bottom edge of the sound amplification channel is provided with a chamfered corner.

[0014] Preferably, the outer wall of the support base and the inner wall of the mounting post are fixedly connected by a plurality of support plates arranged around the outside of the support base.

[0015] Preferably, the plurality of support plates are arranged in a circumferential array on the outer wall of the support base.

[0016] Preferably, the height of the mounting post is 27 - 28 mm.

[0017] Preferably, a plurality of wire clamping fasteners are fixed on the housing. The plurality of wire clamping fasteners include a pair of wire clamping plates arranged in parallel. A wire clamping groove with a spacing smaller than the wire diameter is formed between the two wire clamping plates.

[0018] Preferably, reinforcing ribs are formed on the sides of the two wire clamping plates away from each other.

[0019] Preferably, the upper parts of the two wire clamping plates are separated from each other to form a wire guiding groove for facilitating the entry of wires.

[0020] Preferably, the edges of the wire clamping plates are chamfered.

[0021] The technical solution provided by the present utility model has the following beneficial effects:

[0022] 1. Through the arrangement of the mounting post and the support base, a horn-shaped sound amplification channel is formed inside the support base. When the buzzer emits sound, due to its relatively high position and the further diffusion of the sound through the sound amplification channel, the purpose of expanding the sound is achieved, and it can better play a prompting role for the staff.

[0023] 2. Through the arrangement of the wire clamping fasteners, when the buzzer is connected to the PCB board wire, the wire is placed into the wire clamping fastener, avoiding the entanglement of the wire position and damage, and improving the service life of the product.

[0024] 3. By restricting the height of the mounting post, the best sound amplification effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
