Unless otherwise specified, "plurality" means two or more.

[0049] With the increasing popularity of smart speakers, people's requirements for sound quality, especially bass, are gradually increasing. Low-frequency sound quality requires an increase in the amplitude of the voice coil in the audio speaker. The increase in the amplitude of the speaker voice coil has higher requirements for the reliability of the internal structure of the speaker. At present, the voice coil in the speaker is generally connected to the speaker's wiring terminal (the wiring terminal of the audio input device) through a silk thread, and the audio signal is input to the voice coil through the silk thread to make the voice coil vibrate. However, this method of connection through a silk thread is not only prone to the problem of silk thread breaking when the voice coil amplitude is large, but also when producing speakers, this silk thread is difficult to set in the speaker through an automated machine, and workers are required to thread the wire manually, affecting the production efficiency of the speaker.

[0050] In view of this, the present invention provides a speaker, which is coated with a conductive coating on the centering support of the speaker, and the voice coil and the terminal of the speaker are electrically connected together through the conductive coating, so that the audio signal can be input to the voice coil through the conductive coating, so that the voice coil vibrates, avoiding the problem of easy wire breakage of the silk thread used in the prior art, and improving the reliability and bass effect of the speaker. In addition, compared with the prior art that requires manual threading of the silk thread, the conductive coating in the speaker provided by the present invention can be conveniently coated by an automated machine, thereby improving production efficiency.

[0052] You can refer to Figures 1 to 8 The embodiment of the present invention provides a loudspeaker 100, including a basin frame 110, a magnet unit 120, a voice coil 130, a paper cone 140, a folding ring 150, a centering support 160 and a conductive coating 170. The basin frame 110 is used to support and fix other components; the magnet unit 120 is arranged at the bottom of the basin frame 110, and is used to generate a magnetic field to make the voice coil 130 vibrate; the voice coil 130 is arranged in the basin frame 110, and is used to convert an audio signal into vibration in the magnetic field generated by the magnet unit 120; the paper cone 140 is arranged in the basin frame 110 and is connected to the voice coil 130, and is used to support the voice coil 130 and vibrate the voice coil 130. The vibration of the voice coil 130 is converted into sound and then propagated; the folded ring 150 is connected between the basin frame 110 and the paper cone 140; the centering support 160 is arranged in the basin frame 110 and is sleeved on the outside of the voice coil 130, and is used to support and limit the voice coil 130; the conductive coating 170 is coated on the centering support 160, one end of the conductive coating 170 extends to the terminal 180 on the basin frame 110 and is electrically connected to the terminal 180, and the terminal 180 is used to be electrically connected to the audio signal input device, and the other end of the conductive coating 170 extends to the voice coil 130 and is electrically connected to the power lead of the voice coil 130.

[0053] The specific structure of the magnet unit 120 is not limited, as long as it can provide the required stable magnetic field for the voice coil 130. For example, the magnet unit 120 may include a gasket, a magnet, an iron core and other structures.

[0054] In the above embodiment, the shape of the basin frame 110 is not specifically limited, and its shape can be designed according to actual needs. Specifically, the cross-sectional shape of the basin frame 110 can be circular, square or elliptical.

[0055] The speaker 100 provided in the embodiment of the present invention can achieve a stable electrical connection between the voice coil 130 and the terminal 180 by coating a conductive coating 170 on the centering support plate 160, and electrically connecting the voice coil 130 and the terminal 180 of the speaker 100 through the conductive coating 170. On the one hand, the problem of easy disconnection of traditional silk thread is avoided, and the reliability of the speaker 100 is greatly improved. During use, the user does not have to worry about the sudden failure of the speaker 100 due to disconnection, and can continue to enjoy high-quality audio output. Moreover, this improvement can also enhance the bass effect, making the music fuller and deeper, and bringing a better listening experience to the user. On the other hand, compared with the existing manual threading of silk thread, the conductive coating 170 can be applied by an automated machine, which greatly improves production efficiency, especially in large-scale production, can save a lot of manpower and time costs, and also ensure the consistency of product quality. In addition, the design of the loudspeaker 100 in the embodiment of the present invention can also make the structure of the loudspeaker 100 more compact. Specifically, since the conductive coating 170 is directly coated on the centering support 160, it does not need to occupy additional space like the silk thread in the prior art, so that the loudspeaker 100 can be more compact and delicate as a whole, and is easy to install in various devices. Moreover, since the conductive coating 170 is more stable, the loudspeaker 100 can maintain good performance under different environmental conditions and will not easily fail.

[0056] In the above embodiment, the conductive coating 170 may be in a strip shape. By designing the conductive coating 170 in a strip shape, the direction of the current can be controlled more accurately. It can be understood that the strip shape has a clear directionality. The audio signal can flow more stably and efficiently in the process of being transmitted to the voice coil 130 through the conductive coating 170, reducing the scattering and loss of the signal. Moreover, the strip shape can flexibly adjust the width and length according to different design requirements of the speaker 100, adapt to voice coils 130 of various sizes and powers, and improve the versatility of the design. Secondly, the strip-shaped conductive coating 170 can also better match the shape and structure of the centering support 160, so that the conductive coating 170 and the centering support 160 are more tightly combined, reducing problems caused by looseness or poor contact. In addition, during the production process, the strip-shaped conductive coating 170 is also easier to be accurately coated by an automated machine, ensuring the consistency and quality stability of production.

[0057] In the above embodiment, the thickness of the conductive coating 170 can be 10 μm-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, due to the increase in resistance, the heat generation of the conductive coating 170 will increase, and the failure rate of the speaker 100 will increase. Secondly, if the thickness of the conductive coating 170 is too small, it may be easily damaged during use, such as being scratched or slightly hit, which reduces the reliability of the speaker 100. In addition, if the thickness of the conductive coating 170 is too small, it is not easy to process with existing equipment, and it is difficult to ensure the processing accuracy. If the thickness of the conductive coating 170 is too large, on the one hand, it will increase the production cost, and on the other hand, the overly thick conductive coating 170 will also take up more space, affecting the air flow and heat dissipation inside the speaker 100, thereby affecting the performance and life of the speaker 100.

[0058] In the above embodiment, the width of the conductive coating 170 can be designed to be 1 mm-10 mm. Specifically, when the width of the conductive coating 170 is narrow, the resistance of the conductive coating 170 increases, thereby reducing the conductive performance of the conductive coating 170. When the width of the conductive coating 170 is too large, the production cost will increase.

[0059] In the above embodiment, the connection between the conductive coating 170 and the power lead of the voice coil 130 can be covered with an insulating protective glue, and the connection between the conductive coating 170 and the terminal 180 can be covered with an insulating protective glue. Among them, by providing the insulating protective glue, it is possible to prevent the conductive coating 170 from contacting other metal parts and causing a short circuit, thereby ensuring that the speaker 100 operates safely and stably. Secondly, the insulating protective glue can also protect the conductive coating 170 from external environmental factors, such as moisture, dust, etc., and extend the service life of the conductive coating 170. Furthermore, the insulating protective glue can also play a buffering role to a certain extent, reducing the mechanical damage to the conductive coating 170 during the vibration of the speaker 100.

[0060] In the above embodiment, the conductive coating 170 can be a conductive silver paste coating. The conductive silver paste coating has excellent conductivity and allows current to pass quickly and stably, making the speaker 100 more efficient. Secondly, the conductive silver paste coating has good adhesion and can be firmly attached to the centering support sheet 160 of the speaker 100, and is not easy to fall off, thereby ensuring long-term reliability. The conductive silver paste coating also has a certain degree of flexibility, which can adapt to the vibration and deformation of the speaker 100 during operation, and is not prone to cracking and falling off.

[0061] In the above embodiment, the conductive coating 170 may include a first conductive coating 170 and a second conductive coating 170, and the first conductive coating 170 and the second conductive coating 170 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 exerted on the voice coil 130 in the magnetic field can be more balanced, so that the vibration of the voice coil 130 is more stable and less likely to be biased to one side, thereby reducing the noise and distortion problems caused by the uneven vibration of the voice coil 130. Secondly, the symmetrical design of the conductive coating 170 can also make the heat generated by the voice coil 130 during operation evenly dissipated to both sides, avoiding overheating of one side and affecting the performance and service life of the speaker 100. At the same time, uniform heat dissipation also helps to maintain the temperature inside the speaker 100 stable and reduce the changes in material properties caused by temperature changes. Furthermore, the symmetrical design of the conductive coating 170 can also provide better support and balance for the voice coil 130 when it is subjected to external impact or vibration, reducing the risk of deformation or damage of the voice coil 130 due to uneven force, thereby improving the reliability and durability of the speaker 100. In addition, the conductive coating 170 with a symmetrical structure is also easier to achieve standardized and automated production, which can further improve production efficiency, reduce production costs, and ensure the consistency of product quality.

[0062] In the above embodiment, a dust cap 190 may be further included. The dust cap 190 may be covered on the top of the voice coil 130 and bonded to the inner wall of the paper cone 140. The dust cap 190 may effectively prevent dust and debris from entering the interior of the speaker 100, thereby extending the service life of the speaker 100 and reducing problems such as damage to the voice coil 130 and sound distortion caused by dust accumulation. Secondly, the dust cap 190 may also affect the diffusion and directivity of the sound, making the sound more concentrated and diffused more evenly.

[0063] In addition, an embodiment of the present invention further provides an electronic device, which includes the speaker 100 in the above embodiment, and the speaker 100 includes a basin frame 110, a magnet unit 120, a voice coil 130, a paper cone 140, a folding ring 150, a centering support 160 and a conductive coating 170. The basin frame 110 is used to support and fix other components; the magnet unit 120 is arranged at the bottom of the basin frame 110, and is used to generate a magnetic field that makes the voice coil 130 vibrate; the voice coil 130 is arranged in the basin frame 110, and is used to convert an audio signal into vibration in the magnetic field generated by the magnet unit 120; the paper cone 140 is arranged in the basin frame 110 and is connected to the voice coil 130. It is used to support the voice coil 130 and convert the vibration of the voice coil 130 into sound for transmission; the folded ring 150 is connected between the basin frame 110 and the paper cone 140; the centering support plate 160 is arranged in the basin frame 110 and is sleeved on the outside of the voice coil 130, and is used to support and limit the voice coil 130; the conductive coating 170 is coated on the centering support plate 160, one end of the conductive coating 170 extends to the terminal 180 on the basin frame 110 and is electrically connected to the terminal 180, the terminal 180 is used to be electrically connected to the audio signal input device, and the other end of the conductive coating 170 extends to the voice coil 130 and is electrically connected to the power lead of the voice coil 130. The speaker 100 is coated with a conductive coating 170 on the centering support plate 160. The conductive coating 170 electrically connects the voice coil 130 and the terminal 180 of the speaker 100 together, so that the audio signal can be input to the voice coil 130 through the conductive coating 170, causing the voice coil 130 to vibrate, thereby avoiding the problem of easy breakage of the silk thread used in the prior art and improving the sound effect of the electronic device.
