Description

Easy-to-manufacture stable loudspeakers Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and more specifically, to a stable loudspeaker that is easy to manufacture. Background Technology

[0002] Loudspeakers are a very common electroacoustic transducer and are widely used in electronic and electrical equipment that produce sound.

[0003] However, existing loudspeakers suffer from problems such as complex processes, cumbersome positioning, and lack of modular design in the connection of voice coil leads and brackets, diaphragm assembly, and magnetic circuit assembly. They also have shortcomings in connection stability, vibration performance, and heat dissipation. As a result, existing loudspeakers have low production efficiency, are difficult to mass-produce, and are prone to performance instability and short service life during long-term use.

[0004] In view of this, the present invention proposes a stable loudspeaker that is easy to manufacture. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stable loudspeaker that is easy to manufacture, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-manufacture stable loudspeaker, including a bracket, voice coil, diaphragm, washer, magnet, and U-cup.

[0007] To ensure a stable connection between the voice coil and the bracket by ensuring a one-to-one correspondence between the leads and the soldering station and fixing them with solder, thereby reducing the risk of poor contact or detachment and ensuring long-term stable operation of the loudspeaker, preferably, the voice coil has leads, the bracket is provided with soldering stations, and the leads of the voice coil are fixed to the soldering stations of the bracket with solder. The voice coil has two leads, and the bracket has two soldering stations, each corresponding to one of the two leads of the voice coil.

[0008] To achieve a stable connection and optimized vibration performance between the diaphragm, voice coil, and support, and to ensure stable speaker sound quality, the diaphragm preferably has an inner diameter and an outer diameter. The inner diameter of the diaphragm is bonded to the voice coil, and the outer diameter is bonded to the support. The diaphragm is made of carbon fiber reinforced polyetherimide composite material. An annular damping ring is provided around the edge of the outer diameter of the diaphragm. The inner side of the annular damping ring is integrally formed with the diaphragm, and the outer side is bonded to the support. The annular damping ring can be made of silicone. The bonding between the diaphragm and the voice coil is flexible and allows for deformation space.

[0009] To achieve a stable magnetic circuit through modular bonding of the U-cup, magnet, and washer, and combined with the heat dissipation design of the microchannels on the sidewall of the U-cup, the magnetic circuit structure is made stable, magnetic leakage is reduced, and high-temperature demagnetization of the magnet is avoided, thus achieving long-term stable performance of the magnetic circuit. Furthermore, the assembly method using adhesive bonding improves production convenience. Preferably, the U-cup, magnet, and washer form the magnetic circuit part, and after passing the magnetization test, they are bonded to the corresponding part of the bracket with adhesive. The bottom of the magnet is bonded to the bottom of the inner cavity of the U-cup with adhesive, and the bottom of the washer is bonded to the top of the magnet. The sidewall of the U-cup has multiple microchannels along the axial direction. One end of each microchannel connects to the contact surface between the magnet and the U-cup, and the other end extends to the outer wall of the U-cup.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. The assembly process is simplified by using a one-to-one welding design between the voice coil leads and the bracket soldering station, a quick bonding structure between the diaphragm, voice coil, and bracket, and a modular assembly method for the magnetic circuit. This reduces complex procedures and installation errors, significantly improves production efficiency, adapts to the needs of large-scale assembly line production, and facilitates rapid production.

[0012] 2. The stable welding of the voice coil and the bracket ensures the continuity of the electrical connection. The flexible bonding of the diaphragm and the reserved deformation space avoid aging and breakage under long-term vibration. The annular damping ring effectively suppresses high-frequency vibration distortion. The heat dissipation microchannel in the magnetic circuit prevents the magnet from demagnetizing at high temperatures, ensuring the vibration stability, performance consistency and operational reliability of the speaker during long-term use.

[0019] 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.

[0020] As shown in Figures 1-5, the easy-to-manufacture stable loudspeaker includes a bracket 1, a voice coil 2, a diaphragm 3, a washer 4, a magnet 5, and a U-cup 6.

[0021] In this embodiment, as shown in Figures 1, 2, and 3, the voice coil 2 has leads 20, and the bracket 1 is provided with soldering stations 10. The leads 20 of the voice coil 2 are fixed to the soldering stations 10 of the bracket 1 by solder. The voice coil 2 has two leads 20, and there are two soldering stations 10 on the bracket 1, which correspond to the two leads 20 of the voice coil 2 respectively.

[0022] Specifically, in this structure, the one-to-one correspondence between the lead wire 20 and the soldering station 10, as well as the fixing effect of the solder, ensures the stability of the connection between the voice coil 2 and the bracket 1, reduces the risk of poor contact or detachment, and thus ensures the stable operation of the loudspeaker during long-term use.

[0023] In this embodiment, as shown in Figures 1 and 4, the diaphragm 3 has an inner diameter and an outer diameter. The inner diameter of the diaphragm 3 is bonded to the voice coil 2, and the outer diameter of the diaphragm 3 is bonded to the support 1. The diaphragm 3 is made of carbon fiber reinforced polyetherimide composite material. An annular damping ring 30 is provided on the edge of the outer diameter of the diaphragm 3. The inner side of the annular damping ring 30 is integrally formed with the diaphragm 3, and the outer side is bonded to the support 1. The annular damping ring 30 can be made of silicone. The bonding between the diaphragm 3 and the voice coil 2 is a flexible bonding and has reserved deformation space.

[0024] Specifically, in this structure, the diaphragm 3 combines lightweight and rigidity with its own material to ensure frequency response performance. The deformation space at the flexible bonding point can avoid aging and breakage under long-term vibration. The annular damping ring 30 can suppress the edge segmentation vibration of the diaphragm 3 during high-frequency vibration. Overall, it achieves a stable connection between the diaphragm 3, the voice coil 2, and the support 1, and optimizes the vibration performance.

[0025] In this embodiment, as shown in Figure 5, the U-cup 6, the magnet 5, and the washer 4 constitute the magnetic circuit part, and after the magnetization is qualified, they are bonded to the corresponding part of the bracket 1 with glue. The bottom of the magnet 5 is bonded to the bottom of the inner cavity of the U-cup 6 with glue, and the bottom of the washer 4 is bonded to the top of the magnet 5. The side wall of the U-cup 6 has multiple microchannels 7 along the axial direction. One end of the microchannel 7 is connected to the contact surface between the magnet 5 and the U-cup 6, and the other end extends to the outer wall of the U-cup 6.

[0026] Specifically, in this structure, the magnet 5, washer 4 and U-cup 6 are bonded together in sequence to form a stable magnetic circuit. After being magnetized and qualified, they are glued to the corresponding parts of the bracket 1 to achieve overall assembly. The microchannel 7 on the U-cup 6 can dissipate the heat generated by the magnet 5 during operation through air convection, ensuring the stability of the magnetic circuit performance. At the same time, the bonding and cooperation of each component ensures the integrity of the magnetic circuit structure, which helps to reduce magnetic leakage and enhance the driving force of the magnetic field.

[0027] Working principle of this utility model:

[0028] This application provides a stable loudspeaker that is easy to manufacture. During the installation process, the matching dimensions of the single loudspeaker and the upper and lower shells are calculated to determine the opening size of the upper and lower shells and the loudspeaker selection, providing a precise basis for subsequent assembly.

[0029] First, the voice coil 2 and the bracket 1 are assembled. The two leads 20 of the voice coil 2 are soldered to the two soldering stations 10 of the bracket 1 respectively. Through the one-to-one correspondence design between the leads 20 and the soldering stations 10, the welding and fixing are completed quickly, reducing installation errors, improving production efficiency, ensuring the stability of the connection between the voice coil 2 and the bracket 1, and reducing the risk of poor contact or detachment.

[0030] Next, the diaphragm 3 is assembled. The inner diameter of the diaphragm 3 is flexibly bonded to one side of the bottom of the voice coil 2, leaving room for deformation. At the same time, the outer diameter of the diaphragm 3 is bonded to the top of the bracket 1. The diaphragm 3 is made of carbon fiber reinforced polyetherimide composite material. Its material properties can achieve both lightness and rigidity without complicated processing. The inner side of the silicone annular damping ring 30 on the edge of the outer diameter of the diaphragm 3 is integrally formed with the diaphragm 3, and the outer side is directly bonded to the bracket 1. This can suppress the edge splitting vibration when the diaphragm 3 vibrates at high frequencies, and can quickly complete the stable connection between the diaphragm 3, the voice coil 2, and the bracket 1, which is convenient for rapid assembly.

[0031] Finally, the magnetic circuit is assembled and fixed as a whole. The bottom of the magnet 5 is glued to the bottom of the inner cavity of the U cup 6, and the bottom of the washer 4 is glued to the top of the magnet 5 to form the magnetic circuit. After magnetization and testing, it is connected to the corresponding part of the bracket 1 with glue. The axial microchannel 7 on the side wall of the U cup 6 can dissipate the heat generated by the magnet 5 during operation by means of air convection, ensuring the stability of the magnetic circuit performance.

[0032] In summary, the speaker's design, which involves one-to-one welding of leads 20 to the soldering station 10, quick bonding of diaphragm 3 to voice coil 2 / support 1, and modular assembly of magnetic circuit components, simplifies the assembly process, reduces complex procedures, and facilitates production. Furthermore, the stable welding of voice coil 2 to support 1, the flexible bonding of diaphragm 3 and damping ring design, and the heat dissipation and fixing structure of the magnetic circuit collectively ensure the speaker's connection stability, vibration reliability, and performance consistency during long-term use. Its high stability makes it suitable for scenarios with stringent requirements for both production efficiency and product performance.
