[0050] With the continuous popularity of smart speakers, people's requirements for sound quality, especially bass, are gradually increasing.

[0053] Reference can be made to Figures 1 to 8The utility model embodiment provides a kind of loudspeaker 100, including basin frame 110, magnet unit 120, voice coil 130, paper basin 140, folded ring 150, centering support piece 160 and conductive coating 170, basin frame 110 is used to support and fix other components;Magnet unit 120 is set to the bottom of basin frame 110, for generating the magnetic field that makes voice coil 130 vibrate;Voice coil 130 is set to the inside of basin frame 110, for converting audio signal into vibration in the magnetic field generated by magnet unit 120;Paper basin 140 is set to the inside of basin frame 110, and is connected with voice coil 130, for supporting voice coil 130, and the vibration of voice coil 130 is converted into sound and is propagated after;Folded ring 150 is connected between basin frame 110 and paper basin 140;Centering support piece 160 is set to the inside of basin frame 110, and is sleeved in the outside of voice coil 130, for supporting and limiting voice coil 130;Conductive coating 170 is coated on centering support piece 160, one end of conductive coating 170 extends to terminal 180 on basin frame 110, and is electrically connected with terminal 180, terminal 180 is used to and audio signal input device electrically connected, the other end of conductive coating 170 extends to voice coil 130, and is electrically connected with power supply lead of voice coil 130.

[0054] Wherein, the specific structure of magnet unit 120 is not limited, as long as it can provide the required stable magnetic field for voice coil 130, for example, magnet unit 120 can include gasket, magnet and iron core and other structures.

[0055] In the above embodiment, the shape of basin frame 110 is not limited, and its shape can be designed according to actual needs, specifically, the cross-sectional shape of basin frame 110 can be circular, square or oval.

[0056] The loudspeaker 100 provided by the embodiment of the utility model can realize stable electrical connection of the voice coil 130 and the wiring terminal 180 by coating the conductive coating 170 on the centering support piece 160 and electrically connecting the voice coil 130 and the wiring terminal 180 of the loudspeaker 100 through the conductive coating 170, on the one hand, the problem of easy wire breakage of the traditional silk thread is avoided, and the reliability of the loudspeaker 100 is greatly improved. In the use process, the user does not have to worry about the sudden failure of the loudspeaker 100 caused by wire breakage, and can continuously enjoy high-quality audio output. Moreover, this improvement can also improve the bass effect, so that the music is more full and deep, and brings a better auditory experience to the user. On the other hand, compared with the existing manual silk thread threading, the conductive coating 170 can be coated by an automatic machine, greatly improving the production efficiency, especially in large-scale production, a large amount of manpower and time cost can be saved, and the consistency of product quality can also be guaranteed. In addition, the loudspeaker 100 in the embodiment of the utility model can also make the structure of the loudspeaker 100 more compact, specifically, since the conductive coating 170 is directly coated on the centering support piece 160, it does not need to occupy extra space like the silk thread in the prior art, so that the loudspeaker 100 as a whole is more compact and delicate, and is convenient to install in various devices. Moreover, since the stability of the conductive coating 170 is higher, the loudspeaker 100 can maintain good performance under different environmental conditions and will not easily malfunction.

[0057] In the above embodiment, the conductive coating 170 can be in a strip shape. The conductive coating 170 is designed in a strip shape, which can more accurately control the direction of the current. It can be understood that the strip shape has clear directionality, and the audio signal can flow more stably and efficiently during transmission to the voice coil 130 through the conductive coating 170, reducing signal scattering and loss. Moreover, the strip shape can be flexibly adjusted in width and length according to different loudspeaker 100 design requirements, adapting to voice coils 130 of various sizes and powers, and improving the design versatility. Secondly, the strip-shaped conductive coating 170 can better match the shape and structure of the centering support piece 160, making the combination between the conductive coating 170 and the centering support piece 160 more compact, reducing problems caused by looseness or poor contact. In addition, the strip-shaped conductive coating 170 is also easier to be accurately coated by an automatic machine during production, ensuring the consistency and quality stability of production.

[0058] In the above embodiment, the thickness of the conductive coating 170 can be 10-300 μm. If the thickness of the conductive coating 170 is too small, the resistance of the conductive coating 170 will increase, and the conductive performance of the conductive coating 170 will decrease. In addition, the increase in resistance will also increase the heat generated by the conductive coating 170, and the failure rate of the loudspeaker 100 will increase. In addition, the thickness of the conductive coating 170 is too small, and it is easy to be damaged during use, such as being scratched or being slightly impacted, which reduces the reliability of the loudspeaker 100. In addition, the thickness of the conductive coating 170 is too small, and it is not easy to be processed by existing equipment, and the processing precision cannot be guaranteed. If the thickness of the conductive coating 170 is too large, on the one hand, the production cost will increase, and on the other hand, the thick conductive coating 170 will also occupy more space, which will affect the air flow and heat dissipation inside the loudspeaker 100, and thus affect the performance and service life of the loudspeaker 100.

[0059] In the above embodiment, the width of the conductive coating 170 can be designed to be 1-10 mm. Specifically, if the width of the conductive coating 170 is too small, the resistance of the conductive coating 170 will increase, and the conductive performance of the conductive coating 170 will decrease. If the width of the conductive coating 170 is too large, the production cost will increase.

[0060] In the above embodiment, the connection between the conductive coating 170 and the power supply lead of the voice coil 130 can be covered with insulating protective glue, and the connection between the conductive coating 170 and the terminal 180 can also be covered with insulating protective glue. The insulating protective glue can prevent the conductive coating 170 from contacting other metal parts and causing short circuit, thereby ensuring the safe and stable operation of the loudspeaker 100. In addition, the insulating protective glue can also protect the conductive coating 170 from the influence of external environmental factors such as humidity and dust, thereby prolonging the service life of the conductive coating 170. Furthermore, the insulating protective glue can also play a buffering role to a certain extent, and reduce the mechanical damage to the conductive coating 170 during the vibration of the loudspeaker 100.

[0061] In the above embodiment, the conductive coating 170 can be a conductive silver glue coating. The conductive silver glue coating has excellent conductive performance, and can allow the current to pass quickly and stably, thereby improving the working efficiency of the loudspeaker 100. In addition, the conductive silver glue coating has good adhesion, and can be firmly attached to the spider 160 of the loudspeaker 100, and is not easy to fall off, thereby ensuring the reliability during long-term use. The conductive silver glue coating also has a certain flexibility, and can adapt to the vibration and deformation of the loudspeaker 100 during operation, and is not easy to crack and fall off.

[0062] In the above embodiments, the conductive coating 170 can include a first conductive coating 170 and a second conductive coating 170, which are symmetrically arranged on both sides of the voice coil 130. It can be understood that by symmetrically arranging the first conductive coating 170 and the second conductive coating 170 on both sides of the voice coil 130, the Ampere force experienced by the voice coil 130 in the magnetic field can be more balanced, thereby making the vibration of the voice coil 130 more stable and less likely to deviate to one side, reducing the problem of noise and distortion caused by uneven vibration of the voice coil 130. Secondly, the symmetric design of the conductive coating 170 can also make the heat generated by the voice coil 130 during operation evenly dissipate to both sides, avoiding overheating on one side and affecting the performance and service life of the loudspeaker 100. At the same time, uniform heat dissipation also helps to maintain the temperature stability inside the loudspeaker 100, reducing the change in material properties caused by temperature changes. Furthermore, the symmetric design of the conductive coating 170 can also provide better support and balance to the voice coil 130 when subjected to external force impact or vibration, reducing the risk of deformation or damage of the voice coil 130 due to uneven force, and improving the reliability and durability of the loudspeaker 100. In addition, the symmetric structure of the conductive coating 170 is also easier to realize standardization and automation production, which can further improve the production efficiency, reduce the production cost, and ensure the consistency of product quality.

[0063] In the above embodiments, a dust cap 190 can also be included, which can be arranged on the top end of the voice coil 130 and bonded to the inner wall of the cone 140. The dust cap 190 can effectively block dust and debris from entering the interior of the loudspeaker 100, thereby prolonging the service life of the loudspeaker 100 and reducing problems such as damage to the voice coil 130 and sound distortion caused by dust accumulation. Secondly, the dust cap 190 can also affect the diffusion and directivity of sound, making the sound more concentrated and evenly diffused.
