[0058] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0059] Speakers are an important part of sound boxes, which are commonly used electronic devices in life. They provide great convenience for people to enjoy music and social activities. In order to enhance people's experience of enjoying music, people have developed speakers with luminous devices. Light sources are installed on the periphery of the speakers to emit light synchronously during the working hours of the speakers, producing beautiful and gorgeous visual effects. In order to achieve the luminous effect, speakers on the market currently need to be equipped with luminous components, which need to occupy the space of the sound cavity and avoid interference between structures (the diaphragm and even the elastic wave need to be set to be light-transmissive), resulting in a complex speaker structure and increased space occupied.

[0060] In view of this, the present application proposes a speaker 100, Figures 1 to 9 This is a structural schematic diagram of an embodiment of the speaker 100 provided in the present application. The speaker 100 provided in the present application has a simple structure and good heat dissipation. The speaker 100 will be described in detail below in conjunction with the main drawings.

[0061] According to a first aspect of the present application, the present application provides a speaker 100, see Figure 1 , Figure 2 and Figure 3 The loudspeaker 100 includes a magnetic circuit system 1, a vibration system 2 and a light-emitting body 3. The magnetic circuit system 1 is used to generate a magnetic field; the vibration system 2 includes a voice coil 21 and a diaphragm 23, the voice coil 21 and the diaphragm 23 are connected, and the voice coil 21 is used to cooperate with the magnetic field to move along a first direction, so that the voice coil 21 drives the diaphragm 23 to vibrate and make sound along the first direction; the light-emitting body 3 is relatively fixed to the magnetic circuit system 1 and is located in the voice coil 21.

[0062] In the technical solution of the present application, the magnetic circuit system 1 can generate a magnetic field. When an audio current passes through the voice coil 21, the audio current is acted upon by the magnetic field, causing the voice coil 21 to move along a first direction, thereby driving the diaphragm 23 to vibrate and produce sound along the first direction. The light-emitting body 3 is provided so that light and music are combined to form a cool music scene. At the same time, the light-emitting body 3 is relatively fixed to the magnetic circuit system 1 and is located in the voice coil 21, so that no additional space is occupied, and the structure of the entire speaker 100 is more compact.

[0063] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The magnetic circuit system 1 includes a magnetizer 11, which is provided with a first channel 111; the vibration system 2 includes a voice coil 21, which is provided with a second channel 211, and the voice coil 21 is sleeved on the magnetizer 11. The first channel 111 is connected to the second channel 211, and a light-transmitting area 212 is provided on the voice coil 21; the light-emitting body 3 is arranged in the second channel 211, and the light-transmitting area 212 is located on the light-emitting side of the light-emitting body 3.

[0064] In this embodiment, a first channel 111 is formed in the magnetizer 11, and the first channel 111 can discharge the heat generated by the magnetic circuit system 1 and the vibration system 2 when they are working. The light-emitting body 3 is arranged in the second channel 211, and the second channel 211 is connected to the first channel 111. The heat generated by the light-emitting body 3 during the light-emitting operation can also be discharged through the first channel 111. The heat generated by the magnetic circuit system 1, the vibration system 2 and the light-emitting body 3 are all discharged through the first channel 111, so that the speaker 100 is at a suitable temperature, thereby improving the performance of the speaker 100; at the same time, a light-transmitting area 212 is provided on the voice coil 21, and the light generated by the light-emitting body 3 can be emitted through the light-transmitting area 212, so that the speaker 100 achieves a light-emitting effect, thereby improving the aesthetics of the speaker 100.

[0065] It should be noted that the installation method of the light-emitting body 3 is not limited. In some embodiments, the light-emitting body 3 is installed on the inner wall of the voice coil 21. In this way, no additional supporting structure is required, the number of parts is saved, and the weight of the speaker 100 is reduced. In other embodiments, the light-emitting body 3 is installed at one end of the magnet 11 facing the voice coil 21. In this way, the light-emitting body 3 will not interfere with the vibration of the speaker 100, thereby improving the sensitivity of the speaker 100. In some other embodiments, the speaker 100 also includes a first bracket 4, one end of the first bracket 4 extends into the second channel 211, and the light-emitting body 3 is installed at one end of the first bracket 4 extending into the second channel 211. In this way, it will neither interfere with the voice coil 21 nor affect the heat dissipation of the magnet 11.

[0066] Specifically, in this embodiment, the light emitting body 3 is preferably installed through the first bracket 4. In some embodiments, the first bracket 4 includes a support platform and a plurality of extension arms, the plurality of extension arms are arranged around the support platform, the other ends of the plurality of extension arms are connected to the inner side wall of the first channel 111, the support platform extends into the second channel 211, and the light emitting body 3 is arranged on the support platform. In this arrangement, the space occupied by the first bracket 4 is small, and the gaps formed between the plurality of extension arms can connect the first channel 111 and the second channel 211, which is convenient for heat dissipation.

[0067] In some other embodiments, see Figure 5 The first bracket 4 includes a base 41 and a support column 42. Along the extension direction of the first channel 111, the base 41 is located below the magnet 11, and the support column 42 is located on the base 41, that is, the base 41 is located on the side of the magnet 11 away from the voice coil 21, and the base 41 is connected to the magnet 11. In order to facilitate the installation of the light-emitting body 3, the support column 42 passes through the first channel 111 and extends to the second channel 211. The light-emitting body 3 is arranged at one end of the support column 42 away from the base 41.

[0068] The speaker 100 vibrates to make sound during operation, so the speaker 100 will vibrate as long as it is working. In this embodiment, the lamp beads are directly arranged on the first bracket 4, and the first bracket 4 is independent of the magnetic conductor 11 or the voice coil 21. Compared with other embodiments in which the first bracket 4 is fixed by components such as the magnetic conductor 11, the first bracket 4 provided in this embodiment is subjected to less vibration force, less wear, less prone to breakage, and has a longer service life.

[0069] It should be noted that the light-emitting body 3 generates heat when it is working and the magnet 11 also generates heat during its working process. When the support column 42 contacts the magnet 11, the heat generated by the magnet 11 will be transferred to the light-emitting body 3 through the support column 42, and the heat generated by the light-emitting body 3 will also be transferred to the magnet 11 through the support column 42, resulting in heat superposition and temperature rise, which is not conducive to the operation of the speaker 100. Therefore, in this embodiment, the support column 42 is spaced apart from the inner side wall of the first channel 111 on the magnet 11, and the support column 42 and the magnet 11 are not in direct contact. On the one hand, it can avoid the mutual heat transfer between the magnet 11 and the light-emitting body 3; on the other hand, the support column 42 and the magnet 11 are spaced apart, and a certain gap is formed between the support column 42 and the magnet 11, and the gap can connect the first channel 111 and the second channel 211. The heat generated by the light-emitting body 3 can be dissipated through this gap, achieving a heat dissipation effect, rationally utilizing space, and improving heat dissipation efficiency.

[0070] In some embodiments, the support column 42 is provided with a third channel 421 that runs through the body thereof, one end of the third channel 421 is connected to the second channel 211, and the other end of the third channel 421 is connected to the outside. The support column 42 is provided with a light emitter 3, and the heat generated by the light emitter flows out from the third channel 421, thereby achieving a heat dissipation effect. The gap formed between the support column 42 and the inner side wall of the first channel 111 cooperates with the third channel 421 to discharge the heat generated by the light emitter 3, thereby avoiding heat concentration and affecting the operation of the speaker 100. At the same time, the third channel 421 can also reduce the weight of the support column 42 itself, making the structure more lightweight.

[0071] In some embodiments, the diameter of the third channel 421 is D1, the diameter of the second channel 211 is D2, D2≥D1≥aD2, a is the first coefficient, a=0.5. It should be noted that the diameter of the third channel 421 should not be too large or too small. When the diameter of the third channel 421 is too large, the strength of the support column 42 is reduced, and it is easy to be damaged during use. When the diameter of the third channel 421 is too small, the heat dissipation effect is reduced, the heat is concentrated, and the speaker 100 is easily damaged. As a preferred embodiment, D1 / D2 is 0.5, that is, the diameter of the third channel 421 is half the diameter of the second channel 211.

[0072] For ease of installation, in this embodiment, the first channel 111, the second channel 211 and the third channel 421 are coaxially arranged. At the same time, the first channel 111, the second channel 211 and the third channel 421 are coaxially arranged to facilitate the gas flow inside the speaker 100, to dissipate heat, to reduce the possibility of eddy currents generated during gas flow, and to improve heat dissipation efficiency.

[0073] For further information, see Figure 5 In order to facilitate heat dissipation, a plurality of heat dissipation holes 411 are formed on the base 41, and the plurality of heat dissipation holes 411 are arranged around the support column 42, and the plurality of heat dissipation holes 411 are connected to the first channel 111. In this way, even if the base 41 is connected and fixed to the magnetic conductor 11, it will not affect the heat dissipation. Furthermore, the shape of the heat dissipation hole 411 is not limited, and can be circular, fan-shaped, or rectangular.

[0074] It should be noted that when the gap formed between the first channel 111 and the support column 42 is too large, wind noise will be generated during the gas flow, affecting the effect of the speaker 100. When the gap formed between the first channel 111 and the support column 42 is too small, the heat dissipation effect is greatly affected. Specifically, the diameter of the first channel 111 is D3, and the vertical distance between the outer wall of the support column 42 and the inner wall of the first channel 111 is L1, 1mm≤L1≤D3. In this embodiment, L1 can be 1mm, 1.1mm, 1.3mm, 1.5mm, 1.8mm, 2mm, or other data not listed.

[0075] In some embodiments, the vibration system 2 also includes a diaphragm 23, which is mounted on the voice coil 21. The speaker 100 also includes a support system, which includes a basket 24. One end of the basket 24 is connected to the magnetic circuit system 1. A basin cavity is formed in the basket 24. The voice coil 21 and the diaphragm 23 are arranged in the basin cavity. The end of the diaphragm 23 away from the voice coil 21 is fixed to the end of the basket 24 away from the magnetic circuit system 1 through a folded ring 25.

[0076] Furthermore, in order to ensure the light transmission effect, the light transmission area 212 is located on the side of the diaphragm 23 away from the magnetic conductor 11. In this way, the diaphragm 23 and the magnetic conductor 11 will not interfere with the light transmission area 212.

[0077] It should be noted that the voice coil 21 can be manufactured in an integral molding manner or in a split molding manner, and the choice can be made according to actual conditions.

[0078] In some embodiments, see Figure 4 The voice coil 21 is formed in one piece with a light-transmitting material. In order to prevent the light of the light-emitting body 3 from being emitted from other parts, the part of the voice coil 21 other than the light-transmitting area 212 is a light-shielding area 213. In this way, the light can only be emitted through the light-transmitting area 212, thereby improving the aesthetics of the speaker 100. Furthermore, the vibration system 2 also includes a light-shielding member, which is wrapped around the voice coil 21 located under the diaphragm 23, so that a light-shielding area 213 can be formed on the voice coil 21.

[0079] In some embodiments, the light-transmitting material is mainly PET (polyethylene terephthalate). PET has excellent physical and mechanical properties, and its use temperature can reach 120°C. It has excellent electrical insulation, and even at high temperature and high frequency, its electrical properties are still good, and it has good creep resistance, good fatigue resistance, good friction resistance, good dimensional stability, and is not easy to deform.

[0080] Furthermore, the specific type of the shading member is not limited, and an opaque paint may be used to paint the voice coil 21 under the diaphragm 23 black. Kraft paper may also be used to stick the kraft paper on the voice coil 21 under the diaphragm 23.

[0081] In some other embodiments, the voice coil 21 is formed by split molding, where the light-transmitting area 212 is made of a light-transmitting material, and the light-shielding area 213 is made of an opaque material, and then the light-shielding area 213 and the light-transmitting area 212 are connected to form the voice coil 21.

[0082] In some embodiments, the vertical distance between the end of the diaphragm 23 connected to the voice coil 21 and the magnet 11 is H1, and the height of the support column 42 is H2, H2=H1-A, where A is the amplitude of the diaphragm 23 toward the magnet 11. It should be noted that A is the distance from the light-emitting body 3 to the light-transmitting area 212, and the purpose of such a setting is to improve the space utilization. When the light-emitting body 3 is too far away from the light-transmitting area 212, the light-emitting effect is not good, and most of the light is blocked by the light-shielding area 213. When the light-emitting body 3 is too close to the light-transmitting area 212, the user agrees to see the light-emitting body 3 through the light-transmitting area 212.

[0083] In some embodiments, see Figure 6 , Figure 7 and Figure 8 The width of the support column 42 is L2, the vertical distance between the outer wall of the support column 42 and the inner wall of the first channel 111 is L1, the diameter of the first channel 111 is D3, L2=D3-L1. The diameter of the base 41 is L4, and the outer diameter of the magnetizer 11 is L5, L4=0.5L5.

[0084] In some embodiments, see Figure 6 , Figure 7 and Figure 8 , the distance between two adjacent heat dissipation holes 411 is L6, the diameter of the third channel 421 is D1, L6=0.5D1. Among the plurality of heat dissipation holes 411, there are first heat dissipation holes and second heat dissipation holes arranged opposite to each other, the first heat dissipation hole has a first side away from the second heat dissipation hole, the second heat dissipation hole has a second side away from the first heat dissipation hole, and the vertical distance between the first side and the second side is L7, L7=L3-b, b is the second coefficient, b=2mm.

[0085] It should be noted that the specific type of the light emitting body 3 is not limited and can be an LED lamp, an incandescent lamp or other.

[0086] See also Figure 3In some embodiments, the speaker 100 further includes a dust cover 22, which is relatively fixed to the magnetic circuit system 1. More specifically, the dust cover 22 is connected to the voice coil 21, and the dust cover 22 covers the end of the voice coil 21 away from the magnetizer 11. When the voice coil 21 vibrates along the first direction, the dust cover 22 vibrates along the first direction with the voice coil 21. The dust cover 22 has two functions. One function is to prevent dust from flowing into the interior of the speaker 100, and the other function is to shield the light-emitting body 3, so that the user cannot directly see the structure of the light-emitting body 3 during use, thereby improving the aesthetics of the speaker 100. In addition, the dust cover 22 is set on the voice coil 21. When the voice coil 21 vibrates, the dust cover 22 vibrates with the voice coil, and the light-transmitting area 212 also vibrates along the first direction, thereby changing the angle of light emission from the light-emitting body 3, thereby improving the atmosphere of the light.

[0087] Furthermore, the dust cover 22 is an opaque dust cover, and the specific material of the dust cover 22 can refer to conventional designs in the art, which will not be described in detail here.

[0088] In some other embodiments, the speaker 100 further includes a dust cover 22, which is relatively fixed to the magnetic circuit system 1. More specifically, the dust cover 22 is connected to the diaphragm 23. The dust cover 22 is arranged at one end of the diaphragm 23 away from the magnetic conductor 11 and is fixed to the basin frame 24 through a folding ring 25. Such an arrangement can reduce the weight of the voice coil 21 and improve the sensitivity of the speaker 100.

[0089] In some other embodiments, see Figure 4 The vibration system 2 further includes a dust cover 22, which is relatively fixed to the magnetic circuit system 1; more specifically, the dust cover is fixed on the magnetic conductor 11, and the voice coil 21 and the diaphragm 23 can move relative to the dust cover 22 along a first direction.

[0090] Further, in the present embodiment, the voice coil 21 is sleeved on the magnet 11, one end of the first bracket 4 is mounted with the magnet 11 and is located in the voice coil 21, the other end of the first bracket 4 extends out of the voice coil 21, and the light emitting body 3 is mounted at the other end of the first bracket 4, the vibration system 2 further includes a second bracket 26, the second bracket 26 is located in the first bracket 4, one end of the second bracket 26 is connected with the magnet 11, and the other end extends out of the first bracket 4, and the dust cover 22 is mounted at one end of the second bracket 26 away from the magnet 11, so that the dust cover 22 can shield the light emitting body 3. Such a configuration separates the dust cover 22 from the voice coil 21, reduces the weight of the voice coil 21, and improves the sensitivity of the speaker 100.

[0091] In some embodiments, see Figure 3The magnetic circuit system 1 further includes a magnet 12 and a washer 13. The magnet 12 is sleeved on the magnetic conductor 11. In this embodiment, the magnetic conductor 11 is a T-iron, and the washer 13 is arranged on the magnet 12. The T-iron, the magnet 12 and the washer 13 cooperate to form a magnetic field, so that the voice coil 21 is located in the magnetic field. When an audio current passes through the voice coil 21, the audio current is acted upon by the magnetic field, so that the voice coil 21 vibrates and emits sound.

[0092] In some embodiments, the loudspeaker 100 further includes a supporting system, which includes a centering support plate 5 , which is disposed at the junction of the voice coil 21 and the diaphragm 23 and is used to support the diaphragm 23 to prevent the diaphragm 23 from sagging and deforming.

[0093] In the above embodiment, the voice coil 21 serves as the driving unit of the loudspeaker 100. When the sound current signal enters the voice coil 21, the vibration of the voice coil 21 drives the diaphragm 23 to vibrate. The diaphragm 23 is mostly conical. The diaphragm 23 is generally made of natural fiber or artificial fiber. The natural fiber can be cotton, wood, wool, or silk. The artificial fiber can be rayon, nylon, or glass fiber.
