It is used as an alarm sounding device in electronic products such as computers, printers, copiers, alarms and automotive electronic equipment to provide early warning. It is favored by users because of its small size, high sensitivity, low power consumption, good reliability, low price and easy use.

[0003] The Chinese utility model patent with the authorization announcement number CN220305980U discloses a buzzer sound adjustment structure, which achieves the purpose of adjusting the volume of the sound by rotating the sound adjustment plate to control whether the sound-transmitting hole on the sound adjustment plate overlaps with the sound-emitting hole on the fixed sound plate. However, the defect is that the rotation angle of the sound adjustment plate cannot be locked, so the volume of the sound cannot be accurately controlled. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing buzzer sound adjustment structure cannot lock the rotation angle of the sound adjustment plate, and thus cannot accurately control the sound volume.

[0005] In order to solve the above problems, the utility model provides a buzzer sound adjustment structure, including a buzzer body with a sound outlet on the top, a mounting cover is threadedly connected to the sound outlet, a plurality of sound outlet holes are opened on the side surface of the mounting cover, the top of the mounting cover is threadedly connected to a bolt, an adjusting disk is installed at the lower end of the bolt, and the adjusting disk slides along the inner wall of the mounting cover.

[0006] The buzzer sound adjustment structure provided by the utility model also has the following technical features:

[0007] The sound outlet holes are arranged in multiple layers up and down, and the diameter of the sound outlet holes is smaller than the thickness of the adjustment disk.

[0008] The lower end of the bolt is rotatably connected to the adjusting disk, a plurality of guide blocks are evenly fixed on the circumference of the adjusting disk, and a vertical groove corresponding to the guide blocks is opened on the inner wall of the mounting cover.

[0009] The sound outlet hole is arranged between two adjacent vertical grooves on the side wall of the installation cover.

[0010] A sound insulation ring is fixed on the outer surface of the adjusting disk, and at least two sound insulation rings are arranged above and below.

[0011] A knob is fixed on the upper end of the bolt, and an outer surface of the knob is provided with anti-slip grooves.

[0012] A sound insulation ring is installed in the sound-emitting opening.

[0013] The utility model has the following beneficial effects: the bolt is rotated to drive the adjusting disk to slide along the inner wall of the mounting cover to change the number of sound outlet holes relatively located below the adjusting disk, thereby adjusting the number of sound outlet holes through which the sound generated from the sound outlet passes, and the specific position of the adjusting disk can be locked, thereby achieving precise adjustment and control of the size of the sound emitted by the buzzer body.

[0016] 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.

[0017] like Figure 1 to Figure 2 As shown, the buzzer sound adjustment structure of the utility model includes a buzzer body 11 with a sound outlet 10 on the top, a mounting cover 21 is threadedly connected to the sound outlet 10, a plurality of sound outlet holes 22 are opened on the side surface of the mounting cover 21, the top of the mounting cover 21 is threadedly connected to a bolt 23, an adjusting disk 24 is installed at the lower end of the bolt 23, and the adjusting disk 24 slides along the inner wall of the mounting cover 21.

[0018] The utility model rotates the bolt 23 to drive the adjusting disk 24 to slide along the inner wall of the mounting cover 21, so as to change the number of the sound outlet holes 22 relatively located below the adjusting disk 24, thereby adjusting the number of the sound holes 22 through which the sound generated from the sound outlet 10 passes, and can lock the specific position of the adjusting disk 24, thereby achieving precise adjustment and control of the size of the sound emitted by the buzzer body 11.

[0019] Preferably, the sound outlet holes 22 are provided with multiple layers up and down, and the diameter of the sound outlet holes 22 is smaller than the thickness of the adjustment disk 24 .

[0020] Preferably, the lower end of the bolt 23 is rotatably connected to the adjustment disk 24 , a plurality of guide blocks 25 are evenly fixed to the adjustment disk 24 in the circumferential direction, and a vertical groove 26 corresponding to the guide blocks 25 is formed on the inner wall of the mounting cover 21 .

[0021] Through the above arrangement, when the bolt 23 rotates and moves up and down, the adjusting plate 24 slides along the vertical groove 26 with the guide block 25 without rotating.

[0022] Wherein, a sealing sound insulation structure such as a rubber strip or sound-absorbing foam is provided between the guide block 25 and the vertical groove 26 .

[0023] Preferably, the sound outlet hole 22 is disposed between two adjacent vertical grooves 26 on the side wall of the mounting cover 21 .

[0024] Preferably, a sound insulation ring 27 is fixed to the outer surface of the adjustment disk 24, and at least two sound insulation rings 27 are arranged above and below.

[0025] Preferably, a knob 28 is fixed to the upper end of the bolt 23 , and the outer surface of the knob 28 is provided with anti-slip grooves.

[0026] Preferably, a sound insulation ring 29 is installed inside the sound outlet 10 .

[0027] The sound insulation ring 27 and the sound insulation circle 29 are both made of sound-absorbing materials such as rubber or sound-absorbing foam.

[0028] The utility model avoids the phenomenon of sound leakage from the connection between the mounting cover 21 and the buzzer body 11 after the mounting cover 21 and the buzzer body 11 are installed through the above arrangement.

[0029] The working principle of the utility model is as follows:

[0030] The mounting cover 21 is mounted in the sound outlet 10 of the buzzer body 11 by means of a thread, and the sound generated in the sound outlet 10 is transmitted through the sound outlet holes 22 on the side wall of the mounting cover 21; the bolt 23 is rotated to drive the adjustment disk 24 to slide along the vertical groove 26 with the guide block 25, so as to change the number of the sound outlet holes 22 relatively located below the adjustment disk 24, so as to adjust the number of the sound generated from the sound outlet 10 passing through the sound outlet holes 22, and at the same time, the specific position of the adjustment disk 24 can be locked under the action of the bolt 23, so as to achieve accurate adjustment and control of the size of the sound emitted by the buzzer body 11;

[0031] Specifically, by rotating the bolt 23 so that it drives the adjusting disk 24 to slide upward, the number of the sound holes 22 relatively located below the adjusting disk 24 increases, and the number of the sound generated from the sound outlet 10 passing through the sound outlet holes 22 increases, thereby increasing the sound emitted by the buzzer body 11; by rotating the bolt 23 in the opposite direction so that it drives the adjusting disk 24 to slide downward, the number of the sound holes 22 relatively located below the adjusting disk 24 decreases, and the number of the sound generated from the sound outlet 10 passing through the sound outlet holes 22 decreases, thereby reducing the sound emitted by the buzzer body 11.

[0032] 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. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
