Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to a buzzer piece in a honeycomb device. Background Art

[0002] Buzzers are widely used in electronic devices, primarily for sounding alarms, alerts, and entertainment effects. Their functions include sounding alarms in safety devices, alerting people to potential dangers, and providing audible prompts in household appliances and automobiles, indicating the completion of an operation or a fault. Structurally, a buzzer typically consists of a sounding unit, a housing, electrodes, and a supporting structure. The sounding unit is the core component, typically using a thin film vibrator or piezoelectric material. These materials vibrate when an electric current is applied, producing sound. The housing, typically made of plastic or metal, protects the internal components and facilitates sound transmission. The electrodes, typically consisting of two metal plates, connect to the power supply. When current flows through them, the sounding unit vibrates. The supporting structure fixes the sound unit to ensure that it is not disturbed by external forces when vibrating; for example, a buzzer cavity structure of an audible and visual alarm disclosed in the authorization announcement number CN217982507U includes a shell and a bottom plate, a sound hole is provided in the middle of the top of the shell, and the interior of the shell is divided into a front cavity and a rear cavity in sequence by a piezoelectric buzzer, a circular ring is bonded to the top of the piezoelectric buzzer, and the top of the circular ring is fixedly connected to the inner wall of the top of the shell; the utility model can bond the piezoelectric buzzer by means of adhesive, and the piezoelectric buzzer can be fixed to the bottom end of the circular ring, and the rubber ring can be supported by the bottom plate, and the circular plate at the top of the bottom plate can limit the rubber ring, which solves the problem of using conductive double-sided tape. The piezoelectric buzzer can be fixedly installed. The sound source of the piezoelectric buzzer sound element mainly comes from the piezoelectric vibration plate. The vibration process easily leads to the technical problem of the piezoelectric buzzer loosening and falling off. However, during the use of the above technical solution, the buzzer is fixed to the circuit board of the sound and light alarm through the base plate and positioning holes. The bolting holes are all extended and arranged in the vertical direction. When the buzzer and the sound and light alarm are working or vibrating, the mechanical stress on the buzzer is concentrated on the bolting point. The local stress can easily lead to the loose connection between the buzzer and the sound and light alarm circuit board, and even cause fatigue fracture of the solder joints after long-term use, thereby affecting the normal operation of the equipment.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The present invention provides an embodiment of a buzzer in a honeycomb device, comprising a buzzer body 1 and a PCB board 3 mounted at the bottom of the buzzer body 1, with pins 4 mounted on both sides of the bottom of the PCB board 3, a sound head 2 disposed on one side of the outer wall of the buzzer body 1, and a buzzer cavity 5 communicating with the buzzer body 1 disposed inside the sound head 2, and four-bolt connectors 6 mounted on the front and rear arc-surface outer walls of the buzzer body 1, the four-bolt connectors 6 being used to form two vertical connection points and two oblique connection points;

[0019] An iron core 101, a magnet 102, and a copper ring 103 are sequentially mounted on the upper surface of the PCB board 3. A vibrating plate 104 is mounted inside the buzzer body 1 above the copper ring 103. An electromagnetic coil 105 is mounted between the iron core 101 and the magnet 102. A cylindrical protrusion is integrally formed at the center of the top of the iron core 101. The outer diameter of the cylindrical protrusion is less than or equal to the inner diameter of the electromagnetic coil 105.

[0020] When the buzzer body 1 is electrically connected to the circuit board of the sound and light alarm through pin 4, current enters the electromagnetic coil 105 through the PCB board 3 and pin 4. The intensity and frequency of the current determine the pitch and loudness of the sound. At this time, an alternating magnetic field is generated around the electromagnetic coil 105 and the copper ring 103. The alternating magnetic field generated by the electromagnetic coil 105 interacts with the magnetic field of the magnet 102. This interaction causes the vibrating plate 104 to vibrate in the up and down or front and back directions, which compresses and expands the surrounding air to form sound waves. This part of the sound wave is transmitted to the surrounding environment through the sound head 2, the buzzer cavity 5 and the air. The vibration frequency of the vibrating plate 104 matches the frequency of the current, thereby emitting a sound of the corresponding frequency.

[0021] The four-bolt connection member 6 includes a double-column connection seat 601 fixed on the outer wall of the buzzer body 1 and two symmetrical hollow oblique-braced columns 602 integrally formed on the outer wall of one side of the double-column connection seat 601. Both sides of the interior of the double-column connection seat 601 are provided with completely penetrating internal threaded holes 605. When the four-bolt connection member 6 is connected to the sound and light alarm circuit board, a through hole that is concentric with the hole position of the double-column connection seat 601 and the hollow oblique-braced column 602 is opened in advance on the sound and light alarm circuit board, and the double-column connection seat 601 and the hollow oblique-braced column 602 are made concentric with the through hole on the sound and light alarm circuit board. Then, the sound and light alarm circuit board, the double-column connection seat 601 and the hollow oblique-braced column 602 are connected by bolts. The design of four connection points can provide more contact surfaces, and the connection points in different directions can better adapt to the thermal expansion caused by temperature changes, avoid loosening or breaking of the connection due to thermal stress, thereby improving the reliability of the overall structure;

[0022] A column head 603 extending obliquely upward is provided on the outer wall of the slope on the side of the double-column connecting base 601 away from the buzzer body 1, and a countersunk hole 604 is provided inside the column head 603. In order to further improve the connection strength between the double-column connecting base 601 and the sound and light alarm circuit board, the staff can take out another bolt so that the bolt can reconnect the column head 603 and the sound and light alarm circuit board to reduce the burden on the remaining connection points.

[0023] When using the embodiment of the present application, the staff first takes out the buzzer body 1 and connects the bottom surface of the buzzer body 1 with the upper surface of the sound and light alarm circuit board. At this time, the pin 4 is connected to the signal pin of the sound and light alarm circuit board until the two are plugged in stably. Then the staff uses the bolts and the four-point connector 6 to firmly install the buzzer body 1 on the sound and light alarm circuit board. At this time, multiple connection points are formed between the buzzer body 1 and the sound and light alarm circuit board, including two vertical and two oblique connection points. The vertical and oblique connection points can provide support in different directions, can effectively disperse the mechanical stress applied to the buzzer, reduce the burden on a single connection point, and thus reduce the risk of loose or broken connections.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
