Abstract
Description
Technical Field
[0001] This utility model relates to the field of buzzer technology, specifically a double-sided corrugated buzzer with concave and convex shapes. Background Technology
[0002] A buzzer is an electronic component that produces sound through the piezoelectric effect. It is usually made of piezoelectric materials, such as lead zirconate titanate or lead magnesium niobate piezoelectric ceramic materials. Silver electrodes are plated on both sides of the ceramic substrate, and after polarization and aging treatment, it is then bonded to a brass or stainless steel sheet.
[0003] In the comparative case, patent publication number CN217982819U discloses a buzzer structure, relating to the field of buzzer technology. It solves the technical problem that current methods typically use a metal substrate and a piezoelectric ceramic sheet connected with high-temperature resistant adhesive. However, under high-frequency vibration, the piezoelectric ceramic sheet, the high-temperature resistant adhesive layer, and the metal substrate are not firmly fixed and are prone to detachment, rendering the buzzer unusable and affecting the alarm effect. The present invention includes a metal substrate, a piezoelectric ceramic sheet bonded to the inside of a circular groove using high-temperature resistant adhesive, and an anti-detachment component inside the circular groove. This component includes four support pillars and several anti-slip protrusions, with the four support pillars evenly fixed to the bottom of the inner wall of the circular groove. This invention effectively strengthens the bond between the metal substrate, the piezoelectric ceramic sheet, and the high-temperature resistant adhesive, effectively reducing the defect of detachment and allowing the buzzer structure to continue to function normally, thus improving the alarm effect.
[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned buzzer structure. The comparative case has a circular groove on the surface of the metal substrate, and an anti-detachment component is set inside the circular groove. This allows the corresponding support column and the anti-slip protrusions on the surface of the support column to make close contact with the high-temperature resistant adhesive. At the same time, the first high-temperature resistant rubber ring, the second high-temperature resistant rubber ring and the extrusion component set in the annular groove are arranged to compress and fix the first high-temperature resistant rubber ring set outside the piezoelectric ceramic sheet under the action of the copper sheet. This effectively makes the metal substrate, piezoelectric ceramic sheet and high-temperature resistant adhesive more secure. The existing buzzer cannot effectively penetrate the vibration sound under the interference of external noise environment to realize the alarm, which reduces the safety of the buzzer.
[0005] Therefore, it is necessary to redesign and modify the buzzer to effectively prevent the sound from failing to penetrate and provide an alarm when the buzzer vibrates under external noise interference. Utility Model Content
[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a corrugated double-sided buzzer slab with good vibration effect, which solves the problem that the vibration sound of the buzzer slab cannot effectively penetrate out to achieve the prompt alarm under the interference of external noise environment.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrugated double-sided buzzer sheet with concave and convex shapes, comprising;
[0008] A ceramic sheet, wherein an electrode sheet is printed on the top of the ceramic sheet, a copper sheet is bonded to the top of the electrode sheet, and auxiliary mechanisms are bonded to the left and right sides of the surface of the ceramic sheet.
[0009] The auxiliary mechanism includes a fan-shaped plate, a nylon rope, and a copper tube. The fan-shaped plate is bonded to the left and right sides of the ceramic sheet surface. The nylon rope is bonded to the top and bottom of the inner wall of the fan-shaped plate. The copper tube is fixedly connected to the inner side of the nylon rope. The surface of the ceramic sheet is printed with protective components.
[0010] As a preferred embodiment of this invention, the protective component includes a ceramic film and heat dissipation fins. The surface of the ceramic film is printed with a ceramic film, and heat dissipation fins are fixedly connected to the left and right sides of the top of the copper sheet.
[0011] As a preferred embodiment of this utility model, reinforcing ribs are fixedly connected to the left and right sides of the top of the fan-shaped plate, and the reinforcing ribs are used in conjunction with the fan-shaped plate.
[0012] As a preferred embodiment of this invention, the number of heat dissipation fins is several, arranged in a ring, and the material of the heat dissipation fins is copper, and the heat dissipation fins are used in conjunction with copper sheets.
[0013] In a preferred embodiment of this invention, the number of copper tubes is several and they are evenly distributed, with the copper tubes located inside the fan-shaped plate.
[0014] As a preferred embodiment of this invention, grooves are provided on both the left and right sides of the ceramic sheet surface, and the ceramic sheet is used in conjunction with the grooves.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model, through the setting of an auxiliary mechanism, enables the ceramic sheet to undergo expansion and contraction deformation under the influence of a voltage field. The deformation of the ceramic sheet causes the fan-shaped plate to vibrate as a whole. The fan-shaped plate relies on the weight difference formed by one end having a nylon rope and copper pipe and the other end not having a nylon rope and copper pipe. This causes the heavier end of the fan-shaped plate to become eccentric when the ceramic sheet deforms, thereby increasing the vibration amplitude. This achieves eccentric wheel-type vibration, avoiding the poor vibration effect of the ceramic sheet alone and the inability to increase the vibration amplitude. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 5 As shown, the present invention provides a corrugated double-sided buzzer chip with concave and convex shapes, comprising:
[0025] Ceramic sheet 1, electrode sheet 2 is printed on the top of ceramic sheet 1, copper sheet 3 is bonded to the top of electrode sheet 2, and auxiliary mechanism 4 is bonded to the left and right sides of the surface of ceramic sheet 1.
[0026] The auxiliary mechanism 4 includes a fan-shaped plate 41, a nylon rope 42, and a copper tube 43. The fan-shaped plate 41 is bonded to the left and right sides of the surface of the ceramic sheet 1. The nylon rope 42 is bonded to the top and bottom of the inner wall of the fan-shaped plate 41. The copper tube 43 is fixedly connected to the inner side of the nylon rope 42. The surface of the ceramic sheet 1 is printed with protective components 5.
[0027] refer to Figure 2 The protective component 5 includes a ceramic film 51 and heat dissipation fins 52. The ceramic film 51 is printed on the surface of the ceramic sheet 1, and heat dissipation fins 52 are fixedly connected to the left and right sides of the top of the copper sheet 3.
[0028] As a technical optimization of this utility model, by setting the protective component 5, the ceramic film 51 can cover the surface of the ceramic sheet 1 to improve heat conduction, and together with the multiple sets of heat dissipation fins 52 on the copper sheet 3, heat is conducted and dissipated, thereby achieving the high temperature resistance of the ceramic sheet 1 and avoiding the phenomenon of corrosion and cracking of the ceramic sheet 1 under long-term high temperature.
[0029] refer to Figure 2 The top left and right sides of the fan-shaped plate 41 are fixedly connected with reinforcing ribs 6, which are used in conjunction with the fan-shaped plate 41.
[0030] As a technical optimization of this utility model, the setting of the reinforcing rib 6 can assist the sector plate 41 in its work and at the same time play a reinforcing role, thus preventing the sector plate 41 from breaking during use.
[0031] refer to Figure 2 There are several heat dissipation fins 52 arranged in a ring. The heat dissipation fins 52 are made of copper and are used in conjunction with copper plates 3.
[0032] As a technical optimization of this utility model, the heat dissipation fins 52 can assist the copper sheet 3 in its work and also play a role in heat dissipation, thus avoiding the inability of a single set of heat dissipation fins 52 to evenly and effectively conduct heat to the copper sheet 3.
[0033] refer to Figure 4 There are several copper tubes 43, which are evenly distributed and located inside the fan-shaped plate 41.
[0034] As a technical optimization of this utility model, the copper tube 43 can assist the sector plate 41 in its work and also play a role in increasing its weight, thus preventing the sector plate 41 from failing to achieve eccentric vibration during the vibration process.
[0035] refer to Figure 5 Grooves are provided on the left and right sides of the surface of ceramic sheet 1, and ceramic sheet 1 is used in conjunction with the grooves.
[0036] As a technical optimization of this utility model, by setting the ceramic plate 1, the vibration frequency of the ceramic plate 1 can be increased, thus avoiding the excessively stable vibration effect due to the flatness of the circular contact surface of the ceramic plate 1.
[0037] The working principle and usage process of this utility model are as follows: In use, electrode plates 2 are printed on the surface of ceramic plate 1, and then bonded to copper plate 3 and connected to power. When the voltage field passes through ceramic plate 1, it is affected by the voltage field and undergoes expansion and contraction deformation. The deformation of ceramic plate 1 causes the fan-shaped plate 41 to vibrate as a whole. The fan-shaped plate 41 relies on the weight difference formed by the nylon rope 42 and copper pipe 43 at one end and the absence of nylon rope 42 and copper pipe 43 at the other end. When ceramic plate 1 deforms, the heavier end of the fan-shaped plate 41 becomes eccentric, thereby increasing the vibration amplitude and realizing the eccentric wheel vibration. When ceramic plate 1 vibrates for a long time, it can conduct heat with the heat dissipation fins 52 on copper plate 3. Since the heat dissipation fins 52 have a large surface area, they can quickly dissipate heat into the surrounding air. At the same time, the air flows between the heat dissipation fins 52 and carries away the heat through thermal convection. In addition, the ceramic film 51 effectively conducts heat away from the surface of ceramic plate 1 and protects it from corrosion and high temperature.
[0038] In summary, this corrugated double-sided buzzer stencil, using a ceramic plate 1, electrode plate 2, copper plate 3, auxiliary mechanism 4, sector plate 41, nylon rope 42, copper tube 43, and protective component 5, works in conjunction with these components. During use, the ceramic plate 1 is affected by the voltage field, causing it to expand and contract. This deformation drives the sector plate 41 to vibrate as a whole. The sector plate 41, with one end supported by the nylon rope 42 and copper tube 43 and the other end without them, creates a weight difference. This causes the heavier end of the sector plate 41 to become eccentric when the ceramic plate 1 deforms, increasing the vibration amplitude. This achieves eccentric wheel-like vibration, avoiding the poor vibration effect of the ceramic plate 1 alone, which cannot increase the vibration amplitude. This solves the problem that existing buzzers cannot effectively penetrate the vibration sound to provide an alarm under external noise interference.
