DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor are within the protection scope of the present application.

[0055] The loudspeaker is an important part of the sound box, and the sound box is an electronic device commonly used in life, which provides great convenience for people to enjoy music and social activities. In order to increase the feeling of people when enjoying music, people have developed sound boxes with light emitting devices. The light emitting source is installed on the periphery of the loudspeaker to emit light synchronously with the working time of the sound box, producing a beautiful and gorgeous visual effect. In the related art, in order to achieve the light emitting effect, the sound box needs to be provided with a light emitting component, which needs 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-transmitting), resulting in complex loudspeaker structure and increased space occupation.

[0056] In view of this, the present application provides a loudspeaker 100. FIGS. 1-9 are structural schematic diagrams of an embodiment of the loudspeaker 100 provided by the present application. The loudspeaker 100 provided by the present application has simple structure and good heat dissipation. The loudspeaker 100 will be described in detail below in combination with the main drawings.

[0057] According to a first aspect of the present application, the present application provides a loudspeaker 100. Please refer to FIGS. 1, 2 and 3. The loudspeaker 100 comprises a magnetic circuit system 1, a vibration system 2 and a light emitter 3. The magnetic circuit system 1 is configured to generate a magnetic field. The vibration system 2 comprises a voice coil 21 and a diaphragm 23. The voice coil 21 and the diaphragm 23 are connected. The voice coil 21 is configured 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 produce sound along the first direction. The light emitter 3 is relatively fixed to the magnetic circuit system 1 and located in the voice coil 21.

[0058] In the technical solution of the present application, the magnetic circuit system 1 can generate a magnetic field. When audio current passes through the voice coil 21, the audio current is subjected to the force of the magnetic field, so that the voice coil 21 moves along the first direction, thereby driving the diaphragm 23 to vibrate along the first direction to produce sound. The light-emitting body 3 is arranged to combine the light with the music 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 located in the voice coil 21, without occupying additional space, so that the structure of the entire loudspeaker 100 is more compact.

[0059] In some embodiments, please refer to FIG. 1, FIG. 2 and FIG. 3, the magnetic circuit system 1 comprises a magnetic conductor 11, and the magnetic conductor 11 is provided with a first channel 111; the vibration system 2 comprises a voice coil 21, and the voice coil 21 is provided with a second channel 211, the voice coil 21 is sleeved on the magnetic conductor 11, the first channel 111 is in communication with the second channel 211, and the voice coil 21 is provided with a light-transmitting area 212; the light-emitting body 3 is arranged in the second channel 211, and the light-transmitting area 212 is located at the light-emitting side of the light-emitting body 3.

[0060] In the present embodiment, the first channel 111 is formed in the magnetic conductor 11, and the first channel 111 can discharge the heat generated by the magnetic circuit system 1 and the vibration system 2 during operation. The light-emitting body 3 is arranged in the second channel 211, and the second channel 211 is in communication with the first channel 111. During the light-emitting operation of the light-emitting body 3, the heat generated by the light-emitting body 3 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 is discharged through the first channel 111, so that the loudspeaker 100 is at a suitable temperature, and the performance of the loudspeaker 100 is improved. At the same time, the voice coil 21 is provided with the light-transmitting area 212, and the light emitted by the light-emitting body 3 can be emitted through the light-transmitting area 212, so that the loudspeaker 100 achieves the light-emitting effect and the aesthetic degree of the loudspeaker 100 is improved.

[0061] It should be noted that the mounting mode of the light-emitting body 3 is not limited. In some embodiments, the light-emitting body 3 is mounted on the inner side wall of the voice coil 21. In this way, no additional support structure is needed, the number of parts is saved, and the weight of the loudspeaker 100 is reduced. In some other embodiments, the light-emitting body 3 is mounted on one end of the magnetic conductor 11 facing the voice coil 21. In this way, the light-emitting body 3 does not interfere with the vibration of the loudspeaker 100, and the sensitivity of the loudspeaker 100 is improved. In some other embodiments, the loudspeaker 100 further comprises a first support 4, one end of the first support 4 extends into the second channel 211, and the light-emitting body 3 is mounted on the end of the first support 4 extending into the second channel 211. In this way, the light-emitting body 3 does not interfere with the voice coil 21 and does not affect the heat dissipation of the magnetic conductor 11.

[0062] Specifically, in the embodiment, the light emitter 3 is installed by the first support 4. More specifically, the first support 4 comprises a support table and a plurality of extension arms, the plurality of extension arms are arranged around the support table, the other ends of the plurality of extension arms are connected with the inner side wall of the first channel 111, the support table extends into the second channel 211, and the light emitter 3 is arranged on the support table. In this way, the first support 4 occupies a smaller space, and the gaps formed between the plurality of extension arms can connect the first channel 111 and the second channel 211, facilitating heat dissipation.

[0063] In some other embodiments, referring to FIG. 5, the first support 4 comprises 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, i.e., the base 41 is located on the side of the magnet 11 away from the voice coil 21, and the base 41 is connected with the magnet 11. In order to facilitate installation of the light emitter 3, the support column 42 extends through the first channel 111 to the second channel 211, and the light emitter 3 is arranged at the end of the support column 42 away from the base 41.

[0064] During the working process of the loudspeaker 100, sound is emitted by vibration. Therefore, the loudspeaker 100 will vibrate as long as it works. In the embodiment, the lamp bead is directly arranged on the first support 4, and the first support 4 is independent of the magnet 11 or the voice coil 21. Compared with the other embodiments in which the magnet 11 and the like are used for fixation, the first support 4 provided in the embodiment is subjected to smaller vibration force and less abrasion, and is less likely to break, thereby having a longer service life.

[0065] It should be noted that the light emitter 3 generates heat during light emission, and the magnet 11 also generates heat during the working process. When the support column 42 is in contact with the magnet 11, the heat generated by the magnet 11 is transferred to the light emitter 3 through the support column 42, and the heat generated by the light emitter 3 is also transferred to the magnet 11 through the support column 42, resulting in heat superposition and temperature rise, which is not conducive to the working of the loudspeaker 100. Therefore, in the 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 is not in direct contact with the magnet 11. On the one hand, the support column 42 and the magnet 11 can avoid mutual heat transfer between the magnet 11 and the light emitter 3. On the other hand, the support column 42 is spaced apart from the magnet 11 to form a certain gap therebetween. The gap can connect the first channel 111 and the second channel 211, the heat generated by the light emitter 3 can be dissipated through the gap, heat dissipation effect is achieved, space is reasonably utilized, and heat dissipation efficiency is improved.

[0066] In some embodiments, the support column 42 is provided with a third channel 421 passing through the body thereof, one end of the third channel 421 being communicated with the second channel 211, and the other end of the third channel 421 being communicated with the outside. The support column 42 is provided with a light emitter 3, and the heat generated by the light emitter 3 flows out from the third channel 421, so as to achieve 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, so as to avoid heat concentration and affect the working of the loudspeaker 100. Meanwhile, the third channel 421 can also reduce the weight of the support column 42 itself, so as to make the structure more lightweight.

[0067] 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 a first coefficient, and 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 the support column 42 is easily damaged in the use process. When the diameter of the third channel 421 is too small, the heat dissipation effect is reduced, heat is concentrated, and the loudspeaker 100 is easily damaged. In an embodiment, D1 / D2 is 0.5, that is, the diameter of the third channel 421 is half of the diameter of the second channel 211.

[0068] In order to facilitate installation, in the present embodiment, the first channel 111, the second channel 211 and the third channel 421 are coaxially arranged. Meanwhile, the coaxial arrangement of the first channel 111, the second channel 211 and the third channel 421 facilitates the flow of gas inside the loudspeaker 100, performs heat dissipation, reduces the possibility of vortex flow in the gas flow process, and improves the heat dissipation efficiency.

[0069] In some embodiments, referring to FIG. 5, in order to facilitate heat dissipation, a plurality of heat dissipation holes 411 are formed on the base 41, the plurality of heat dissipation holes 411 are arranged around the support column 42, and the plurality of heat dissipation holes 411 are communicated with the first channel 111. In this way, even if the base 41 is connected and fixed with the magnet 11, it will not affect heat dissipation. Specifically, the shape of the heat dissipation hole 411 is not limited, which can be circular, sector-shaped, or rectangular.

[0070] 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 in the gas flow process, which affects the effect of the loudspeaker 100. When the gap formed between the first channel 111 and the support column 42 is too small, the heat dissipation effect is affected. Specifically, the diameter of the first channel 111 is D3, and the vertical distance between the outer side wall of the support column 42 and the inner side wall of the first channel 111 is L1, 1mm≤L1≤D3. In the present embodiment, L1 can be 1mm, 1.1mm, 1.3mm, 1.5mm, 1.8mm, 2mm, or other unlisted data.

[0071] In some embodiments, the vibration system 2 further comprises a diaphragm 23, the diaphragm 23 being sleeved on the voice coil 21, the loudspeaker 100 further comprising a support system, the support system comprising a basket 24, one end of the basket 24 being connected with the magnetic circuit system 1, the basket 24 being formed with a basket cavity, the voice coil 21 and the diaphragm 23 being arranged in the basket cavity, and an end of the diaphragm 23 away from the voice coil 21 being fixed to an end of the basket 24 away from the magnetic circuit system 1 through a folded ring 25.

[0072] In some embodiments, in order to ensure the light transmission effect, the light transmission area 212 is located on a side of the diaphragm 23 away from the magnetic conductor 11. In this way, neither the diaphragm 23 nor the magnetic conductor 11 will interfere with the light transmission area 212.

[0073] It should be noted that the voice coil 21 can be manufactured in an integrated manner or in a split manner, and the selection can be made according to the actual situation.

[0074] In some embodiments, referring to FIG. 4, the voice coil 21 is integrally formed in a light transmission material, and in order to avoid the light of the light emitting body 3 from being emitted from other parts of the voice coil 21 except the light transmission area 212, a light shielding area 213 is provided. In this way, the light can only be emitted through the light transmission area 212, and the aesthetic appearance of the loudspeaker 100 is improved.

[0075] In some embodiments, the vibration system 2 further comprises a light shielding member, the light shielding member being wrapped around the voice coil 21 located below the diaphragm 23. In this way, the light shielding area 213 can be formed on the voice coil 21.

[0076] In some embodiments, the light transmission material is mainly PET (polyethylene terephthalate). The PET has excellent physical and mechanical properties, the use temperature can reach 120℃, the electrical insulation is excellent, and even under high temperature and high frequency, the electrical properties are still good, the anti-creep property is good, the fatigue resistance is good, the friction resistance is good, the dimensional stability is good, and the deformation is not easy to occur.

[0077] Specifically, the specific type of the light shielding member is not limited, and the voice coil 21 located below the diaphragm 23 can be painted black by using a non-light transmission paint. The voice coil 21 located below the diaphragm 23 can also be adhered with kraft paper.

[0078] In some other embodiments, the voice coil 21 is formed in a split manner, the light transmission area 212 is prepared by using a light transmission material, the light shielding area 213 is prepared by using a non-light transmission material, and the light shielding area 213 and the light transmission area 212 are connected, so as to form the voice coil 21.

[0079] In some embodiments, the vertical distance between the end of the diaphragm 23 connected with the voice coil 21 and the magnet conductor 11 is H1, the height of the support column 42 is H2, H2=H1-A, where A is the amplitude of the diaphragm 23 towards the magnet conductor 11. It should be noted that A is the distance between the light emitter 3 and the light transmission area 212, and the purpose of such arrangement is to improve the space utilization. When the light emitter 3 is too far away from the light transmission area 212, the lighting effect is not good, and most of the light is blocked by the light shielding area 213. When the light emitter 3 is too close to the light transmission area 212, the user can see the light emitter 3 through the light transmission area 212.

[0080] In some embodiments, referring to FIGS. 6, 7 and 8, the width of the support column 42 is L2, the vertical distance between the outer side wall of the support column 42 and the inner side 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, the outer diameter of the magnet conductor 11 is L5, L4=0.5L5.

[0081] In some embodiments, referring to FIGS. 6, 7 and 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 oppositely arranged first and second heat dissipation holes, the first heat dissipation hole has a first side edge away from the second heat dissipation hole, the second heat dissipation hole has a second side edge away from the first heat dissipation hole, the vertical distance between the first side edge and the second side edge is L7, L7=L3-b, b is a second coefficient, b=2mm.

[0082] It should be noted that the specific type of the light emitter 3 is not limited. It can be an LED lamp, an incandescent lamp or other.

[0083] Referring to FIG. 3, in some embodiments, the loudspeaker 100 further comprises a dust cover 22, which is relatively fixed to the magnetic circuit system 1. More specifically, the dust cover 22 is connected with the voice coil 21, and covers the end of the voice coil 21 away from the magnet conductor 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 loudspeaker 100. The other function is to block the light emitter 3, so that the user cannot see the structure of the light emitter 3 during use, thereby improving the aesthetics of the loudspeaker 100. In addition, by arranging the dust cover 22 on the voice coil 21, when the voice coil 21 vibrates, the dust cover 22 vibrates with the voice coil, and the light transmission area 212 also vibrates along the first direction, thereby changing the angle of the light emitted by the light emitter 3, thereby improving the atmosphere of the light.

[0084] In some embodiments, the dust cover 22 is an opaque dust cover, and the specific material of the dust cover 22 can be designed according to the conventional design in the art, which will not be described here.

[0085] In some other embodiments, the loudspeaker 100 further comprises 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, and the dust cover 22 is arranged at the end of the diaphragm 23 away from the magnetic conductor 11 and is fixed to the spider 24 through the folding ring 25. In this way, the weight of the voice coil 21 can be reduced, and the sensitivity of the loudspeaker 100 can be improved.

[0086] In some other embodiments, referring to FIG. 4, the vibration system 2 further comprises a dust cover 22, which is relatively fixed to the magnetic circuit system 1. More specifically, the dust cover is fixed to the magnetic conductor 11, and the voice coil 21 and the diaphragm 23 are movable relative to the dust cover 22 along the first direction.

[0087] In the present embodiment, the voice coil 21 is sleeved on the magnetic conductor 11, one end of the first support 4 is mounted to the magnetic conductor 11 and located in the voice coil 21, the other end of the first support 4 extends out of the voice coil 21, and the light emitter 3 is mounted to the other end of the first support 4. The vibration system 2 further comprises a second support 26, which is located in the first support 4 and has one end connected to the magnetic conductor 11 and the other end extending out of the first support 4. The dust cover 22 is mounted to the other end of the second support 26 away from the magnetic conductor 11, so that the dust cover 22 can shield the light emitter 3. In this way, the dust cover 22 is separated from the voice coil 21, the weight of the voice coil 21 is reduced, and the sensitivity of the loudspeaker 100 is improved.

[0088] In some embodiments, referring to FIG. 3, the magnetic circuit system 1 further comprises a magnet 12 and a dust cup 13. The magnet 12 is sleeved on the magnetic conductor 11. In the present embodiment, the magnetic conductor 11 is a T-shaped iron, and the dust cup 13 is arranged on the magnet 12. The T-shaped iron, the magnet 12, and the dust cup 13 cooperate to form a magnetic field, so that the voice coil 21 is located in the magnetic field.
