A loudspeaker using a frame, piezoelectric ceramic sheet and diaphragm fixed assembly.

Abstract

This utility model discloses a loudspeaker using a fixed combination of a frame, a piezoelectric ceramic sheet, and a diaphragm, relating to the field of loudspeaker technology. It includes a frame and a piezoelectric ceramic sheet. The bottom of the frame has a first mounting groove, and the piezoelectric ceramic sheet is placed inside the first mounting groove. The top of the frame has a second mounting groove, and the diaphragm is bonded inside the second mounting groove and fixedly connected to the piezoelectric ceramic sheet. This loudspeaker, using a fixed combination of a frame, a piezoelectric ceramic sheet, and a diaphragm, utilizes the piezoelectric ceramic sheet. During use, applying an AC signal to the piezoelectric ceramic sheet causes it to vibrate, which in turn drives the diaphragm to vibrate and produce sound. Compared to existing loudspeakers that use a magnet, a magnetic plate, and a T-iron to form a magnetic circuit, and then combine a voice coil, a spider, and a diaphragm to form the vibrating part for sound production, this application has a simpler overall structure and greatly improves the yield rate in the loudspeaker manufacturing process.

Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a loudspeaker using a fixed combination of a frame, a piezoelectric ceramic sheet, and a diaphragm. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. Audio electrical energy vibrates its cone or diaphragm through electromagnetic, piezoelectric, or electrostatic effects, causing it to resonate with the surrounding air and produce sound.

[0003] Existing loudspeakers typically use a magnetic circuit consisting of a magnet, a magnetic plate, and a T-iron (U-iron), which is then combined with a voice coil, a spider (positioning support), and a diaphragm to form the vibrating part. When in use, an AC signal is applied to both ends of the voice coil, and the voice coil vibrates up and down in the magnetic field due to the change of magnetic lines of force, which drives the diaphragm to vibrate and produce sound. The overall structure is relatively complicated and the yield rate is not high. Utility Model Content

[0004] The purpose of this invention is to provide a loudspeaker that uses a frame, a piezoelectric ceramic sheet and a fixed combination of a diaphragm to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a loudspeaker using a frame, a piezoelectric ceramic sheet and a diaphragm fixedly combined, comprising a frame and a piezoelectric ceramic sheet, wherein a first mounting groove is provided at the bottom of the frame and a piezoelectric ceramic sheet is placed inside the first mounting groove, and a second mounting groove is provided at the top of the frame and a diaphragm is bonded inside the second mounting groove, and the diaphragm is fixedly connected to the piezoelectric ceramic sheet.

[0006] Furthermore, the diameter of the basin stand is 79.6 mm, and the height of the basin stand is 21.2 mm.

[0007] Furthermore, the bottom of the basin stand is provided with a clearance groove, and a support frame is provided in the middle of one side of the basin stand.

[0008] Furthermore, a stop block is fixed to the inner side of the support frame, and a card plate is provided at the bottom of the support frame.

[0009] Furthermore, the card plate is J-shaped, and the bottom surface of the card plate is inclined.

[0010] Furthermore, mounting plates are provided on both sides of the basin frame, and mounting holes are provided at both ends of the mounting plates.

[0011] Furthermore, a side frame is fixed to the bottom of the mounting plate, and reinforcing ribs are symmetrically arranged on one side of the side frame.

[0012] Furthermore, the reinforcing rib is fixedly connected to the mounting plate, and the reinforcing rib is also fixedly connected to the basin frame.

[0013] This utility model provides a loudspeaker using a combination of a frame, a piezoelectric ceramic sheet, and a diaphragm, which has the following advantages:

[0014] 1. This utility model, through the setting of piezoelectric ceramic sheet, allows the piezoelectric ceramic sheet to vibrate by applying an AC signal during use, thereby driving the diaphragm to vibrate and produce sound. Compared with the existing method of using a magnet, magnetic plate, T-iron to form a magnetic circuit, and then combining a voice coil, spider, and diaphragm to form a vibrating part to produce sound, this application has a simple overall structure and greatly improves the yield rate in the loudspeaker production process.

[0015] 2. By setting up a support frame, this utility model allows the circuit board of the piezoelectric ceramic sheet to be installed simply by placing it inside the support frame. At this time, the clamping plate will deform under pressure to automatically avoid it, while the stop block will limit the top of the circuit board. After the clamping plate resets, it can limit the bottom of the circuit board, thus facilitating the assembly between the circuit board and the frame. At the same time, the avoidance groove is used to avoid the connecting wires between the circuit board and the piezoelectric ceramic sheet, thereby improving the convenience of assembly.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, a loudspeaker using a fixed combination of a frame, a piezoelectric ceramic plate, and a diaphragm includes a frame 1 and a piezoelectric ceramic plate 3. The bottom of the frame 1 has a first mounting groove 2, and the piezoelectric ceramic plate 3 is placed inside the first mounting groove 2. The top of the frame 1 has a second mounting groove 4, and the diaphragm 5 is bonded inside the second mounting groove 4 and fixedly connected to the piezoelectric ceramic plate 3. The diameter of the frame 1 is 79.6 mm and the height of the frame 1 is 21.2 mm. During use, by applying an AC signal to the piezoelectric ceramic plate 3, the piezoelectric ceramic plate 3 vibrates, causing the diaphragm 5 to vibrate and produce sound. The overall structure is simple and greatly improves the yield rate in the production process.

[0022] like Figure 1 and Figure 3 As shown, the bottom of the basin holder 1 has a clearance groove 6, and a support frame 7 is provided in the middle of one side of the basin holder 1. The clearance groove 6 is used to avoid the connecting wires between the circuit board and the piezoelectric ceramic sheet 3. The support frame 7 limits the movement of the circuit board around its perimeter. A stop block 8 is fixed inside the support frame 7, and a retaining plate 9 is provided at the bottom of the support frame 7. The stop block 8 limits the movement of the top of the circuit board. The retaining plate 9 is J-shaped, and the bottom surface of the retaining plate 9 is inclined. When the circuit board is installed, the retaining plate 9 will deform under pressure to automatically avoid the circuit board. After the card plate 9 is reset, it can limit the bottom of the circuit board. The two sides of the basin frame 1 are equipped with mounting plates 10, and the two ends of the mounting plates 10 are provided with mounting holes 11. The mounting plates 10 are fixed by the mounting holes 11. The bottom of the mounting plate 10 is fixed with a side frame 12, and a reinforcing rib 13 is symmetrically arranged on one side of the side frame 12. The reinforcing rib 13 is fixedly connected to the mounting plate 10 and also fixedly connected to the basin frame 1. The reinforcing rib 13 can improve the connection strength between the mounting plate 10 and the basin frame 1.

[0023] In summary, this loudspeaker, which uses a combination of a frame, piezoelectric ceramic sheet, and diaphragm fixing assembly, should first be used according to... Figure 1 , Figure 2 and Figure 3In the structure shown, during assembly, the piezoelectric ceramic sheet 3 and the diaphragm 5 are first bonded to the inside of the first mounting groove 2 and the second mounting groove 4, respectively. Then, the circuit board of the piezoelectric ceramic sheet 3 is placed inside the support frame 7. At this time, the clamping plate 9 will deform under pressure to automatically avoid the pressure. After that, the support frame 7 will limit the horizontal direction of the circuit board, and the stop block 8 will limit the top of the circuit board. After the clamping plate 9 is reset, it can limit the bottom of the circuit board, thus facilitating the installation of the circuit board. At the same time, the avoidance groove 6 is used to avoid the connecting wires between the circuit board and the piezoelectric ceramic sheet 3. Then, the side bracket 12 is inserted into the hole on the device housing, and the mounting plate 10 is fixed with bolts and mounting holes 11, thus completing the speaker installation operation. The reinforcing rib 13 can improve the connection strength between the mounting plate 10 and the frame 1. Finally, during use, by applying an AC signal to the piezoelectric ceramic sheet 3, the piezoelectric ceramic sheet 3 vibrates, causing the diaphragm 5 to vibrate and produce sound.
