Description

TECHNICAL FIELD

[0001] The utility model relates to the field of loudspeaker, especially easy to dismantle and replace a loudspeaker. BACKGROUND

[0002] A loudspeaker, also known as a speaker, is a device that converts electrical signals into sound signals. It is one of the key components in a sound system and is widely used in various audio devices, such as home sound systems, car sound systems, earphones, public broadcasting systems, etc. A speaker is usually composed of a magnetic circuit system and a vibration system. The magnetic circuit system of a speaker is the part that generates and concentrates the magnetic field in the speaker, and it has a significant impact on the performance of the speaker. The magnetic circuit system mainly includes an iron core, a magnet, a copper sleeve, a Hua Si, and other components. The vibration system of a speaker is the key part that converts electrical signals into sound signals, and it mainly includes a diaphragm, a voice coil, a spring, a basket, a dust cap, etc.

[0003] In the prior art, the magnetic circuit system and the vibration system of a speaker are usually directly combined together through a basket. For example, the invention patent with publication number CN117560608B provides a loudspeaker, which includes a basket, a vibration system fixed to the basket, and a magnetic circuit system that drives the vibration system to vibrate. The magnetic circuit system and the vibration system of the loudspeaker are assembled on the basket and housed in the basket. The magnetic circuit system is fixedly suspended in the basket through a damping elastic buffer, and the vibration system is arranged on the other side of the basket and fixedly connected to one end of the basket.

[0004] Therefore, the vibration system and the magnetic circuit system of the loudspeaker are fixedly connected to the basket. When one of the magnetic circuit system and the vibration system is damaged and needs to be disassembled and repaired, it will affect the other system. Especially when the magnetic circuit system is damaged, the vibration system needs to be disassembled first before the magnetic circuit system can be repaired, which leads to inconvenient maintenance of the loudspeaker. Moreover, since the loudspeaker is composed of many components, it takes a lot of time to disassemble and install. SUMMARY

[0005] Therefore, the utility model provides a loudspeaker easy to disassemble and replace to solve the above problems.

[0006] The utility model provides an easily dismountable loudspeaker, which comprises a vibration system and a magnetic circuit system fixedly arranged on one side of the vibration system and used for driving the vibration system.

[0007] Further, the basket comprises a basket body, a connecting rim arranged at one end of the basket body towards the fixing ring, a plurality of fixing ring limiting protrusions arranged at the connecting rim, a plurality of adapter positioning grooves arranged at the other end of the connecting rim away from the fixing ring limiting protrusions, a plurality of first fixing holes arranged at the connecting rim, and a plurality of positioning blocks arranged at one end of the first fixing holes.

[0008] Further, the adapter positioning grooves and the fixing ring limiting protrusions are arranged correspondingly, that is, the positions of the adapter positioning grooves on the circumference of the connecting rim coincide with the positions of the fixing ring limiting protrusions.

[0009] Further, the positioning blocks are arranged at one end of the first fixing holes towards the magnetic circuit system, and are arranged in a circular arc shape on the circumference of the first fixing holes.

[0010] Further, the fixing ring comprises a ring body, a plurality of limiting clamping grooves arranged at equal intervals along the circumferential direction of the ring body, and a plurality of second fixing holes arranged at equal intervals along the circumferential direction of the ring body.

[0011] Further, the limiting clamping grooves and the fixing ring limiting protrusions are arranged correspondingly, and when the fixing ring is mounted on the basket, the fixing ring limiting protrusions are inserted into the limiting clamping grooves.

[0012] Further, the adapter comprises an adapter body fixedly arranged on the magnetic circuit assembly, a plurality of adapter limiting protrusions arranged at one end of the adapter body towards the vibration system, and a plurality of third fixing holes arranged at the adapter body away from the adapter limiting protrusions.

[0013] Further, the first fixing holes, the second fixing holes, and the third fixing holes are arranged correspondingly.

[0014] Compared with the prior art, the loudspeaker easy to disassemble and replace has the vibration assembly installed on the stand assembly to form an independent vibration system, and an adapter frame matched with the stand assembly is arranged on the magnetic circuit system. The vibration system and the magnetic circuit system are connected together through the adapter frame, so that when the vibration system and the magnetic circuit system are disassembled, only the stand assembly and the adapter frame need to be removed, and the structure of the magnetic circuit assembly and the vibration assembly is not affected. Therefore, when the vibration system or the magnetic circuit system is damaged, the vibration system or the magnetic circuit system can be repaired or replaced alone, which improves the maintenance efficiency and saves the assembly time.

[0021] The specific embodiments of the utility model are further described in detail below. It should be understood that the description of the utility model here is not used to limit the protection scope of the utility model.

[0022] As Figures 1 to 6 ​​​​​The diagram shown is a structural schematic of an easily replaceable speaker provided by this utility model. The easily replaceable speaker includes a vibration system 10 and a magnetic circuit system 20 fixedly disposed on one side of the vibration system 10 for driving the vibration system 10. It is conceivable that the easily replaceable speaker should also include some other related functional components, such as assembly components, mounting components, electrical connection components, etc., all of which are prior art known to those skilled in the art and will not be described in detail here.

[0023] The vibration system 10 includes a basin frame assembly 11 fixedly connected to the magnetic circuit system 20, and a vibration component 12 disposed within the basin frame assembly 11.

[0024] The basin frame assembly 11 includes a basin frame 111 and a retaining ring 112 disposed on one side of the free end of the basin frame 111.

[0025] like Figure 4 As shown, the frame 111 is used to fix the spider 121, the tuning coil 122, and the cone 123, etc. It includes a frame body 1111, a connecting edge 1112 disposed on the frame body 1111 facing the fixing ring 112, a plurality of fixing ring limiting protrusions 1113 spaced apart on one side of the connecting edge 1112, a plurality of adapter bracket positioning grooves 1114 opposite to the fixing ring limiting protrusions 1113 and disposed on the other side of the connecting edge 1112, a plurality of first fixing holes 1115 spaced apart on the connecting edge 1112, and a plurality of positioning blocks 1116 correspondingly disposed at one end of the first positioning holes 1115.

[0026] The dimensions of the frame body 1111 are adapted to the dimensions of the spring 121, the voice coil 122, and the cone 123. It is used to set the spring 121, the voice coil 122, and the cone 123 so as to combine the spring 121, the voice coil 122, and the cone 123 into the vibration assembly 12 and maintain the stability and integrity of the entire vibration assembly 12.

[0027] The connecting edge 1112 is integrally disposed with the basin frame body 1111 at one end of the basin frame body 1111 facing the fixing ring 112, thereby facilitating the setting of the fixing ring limiting protrusion 1113, the adapter positioning groove 1114, the first fixing hole 1115 and other connecting structures on the basin frame 111, so as to facilitate the assembly of the fixing ring 112 and the basin frame 111, as well as the vibration system 10 and the magnetic circuit system 20.

[0028] The fixing ring limiting protrusions 1113 are arranged on the connecting edge 1112 at equal intervals along the circumferential direction of the connecting edge 1112. When the fixing ring 112 is installed on the basin frame 111, the fixing ring limiting protrusions 1113 are used to limit the position of the fixing ring 112 in the circumferential direction. The fixing ring limiting protrusions 1113 will be described in further detail below in combination with the fixing ring 112.

[0029] The adapter frame positioning grooves 1114 are arranged on the connecting edge 1112 at equal intervals along the circumferential direction of the connecting edge 1112 and are located on the side of the connecting edge 1112 opposite to the fixing ring limiting protrusions 1113. Preferably, the adapter frame positioning grooves 1114 are arranged in correspondence with the fixing ring limiting protrusions 1113, i.e., the positions of the adapter frame positioning grooves 1114 on the circumference of the connecting edge 1112 coincide with the positions of the fixing ring limiting protrusions 1113, so as to avoid that the connecting edge 1112 is too thin due to the opening of the adapter frame positioning grooves 1114, thereby affecting the service life of the basin frame 111. When the vibration system 10 is combined with the magnetic circuit system 20, the adapter frame positioning grooves 1114 are used to limit the displacement of the vibration system 10 in the circumferential direction.

[0030] A plurality of the first fixing holes 1115 and a plurality of the fixing ring limiting protrusions 1113 are arranged on the connecting edge 1112 at equal intervals, respectively, and penetrate the connecting edge 1112. The first fixing holes 1115 are used to connect the basin frame 111 and the adapter frame 22.

[0031] The positioning block 1116 is arranged at the end of the first fixing hole 1115 towards the magnetic circuit system 20 and can be a circular arc structure and is arranged on the circumference of the first fixing hole 1115, so as to form positioning when the vibration system 10 is connected with the magnetic circuit system 20, making the installation operation easier.

[0032] The fixing ring 112 comprises a ring body 1121, a plurality of limiting clamping grooves 1122 arranged at equal intervals along the circumferential direction of the ring body 1121, and a plurality of second fixing holes 1123 arranged at equal intervals along the circumferential direction of the ring body 1121.

[0033] The ring body 1121 is adapted in size to the connecting edge 1112, and when the vibration system 10 is assembled, the ring body 1121 is fixed together with the connecting edge 1112 in a coincident manner, so as to fix the vibration assembly 12 on the basin frame assembly 11.

[0034] The limiting slot 1122 is matched with the fixing ring limiting protrusion 1113, when the fixing ring 112 is installed on the yoke 111, the fixing ring limiting protrusion 1113 is inserted into the limiting slot 1122, thereby fixing the circumferential position of the fixing ring 112, to avoid the displacement between the fixing ring 112 and the yoke 111 affected by the vibration unit 12 during the use of the speaker, thereby easily causing the clamping between the fixing ring 112 and the yoke 111 to be loose, and further causing the displacement or deformation of the vibration assembly 112.

[0035] The second fixing hole 1123 is correspondingly arranged with the first fixing hole 1115, and the fixing ring 112 and the yoke 111 are fixed together by the second fixing hole 1123 and the first fixing hole 1115 using screws and other fasteners.

[0036] As shown in Figure 3 The vibration assembly 12 converts electrical signals into sound signals under the drive of the magnetic circuit system 20 when working, which includes a spring 121 fixedly arranged inside the yoke assembly 11, a voice coil 122 fixedly connected with the spring 121, an audio cone 123 arranged on one side of the voice coil 122, and a dust cap 124 for sealing the audio cone 123.

[0037] The spring 121 is fixedly arranged at one end of the yoke body 111 towards the magnetic circuit system 20, the outer contour part is fixed on the yoke body 111, and the inner contour is fixedly connected with the voice coil 122. The spring 121 is used to support the voice coil 122, thereby maintaining the correct position of the voice coil 122 in the magnetic gap.

[0038] The voice coil 122 is fixed at the center position of the spring 121 and is fixedly connected with the audio cone 123. When the vibration system 10 is combined with the magnetic circuit system 20, the voice coil 122 is inserted into the magnetic gap formed by the magnetic circuit system 20 at one end towards the magnetic circuit system 20, and moves up and down along its axial direction under the drive of the magnetic circuit system 20, thereby driving the audio cone 123 fixedly connected with the voice coil 14 to vibrate, and further generating sound waves. The voice coil 122 itself is a prior art, which will not be described here.

[0039] The sound cone 123, i.e. the diaphragm of the loudspeaker, is in a horn structure. One side of the horn opening of the sound cone 123 is clamped and fixed between the fixed ring 112 and the yoke 111, and the other side is fixed with the voice coil 122. When the voice coil 122 moves up and down, the sound cone 123 is driven to vibrate by the voice coil 122 to compress air, thereby emitting sound. The size of the sound cone 123 is adapted to the size of the loudspeaker model, and different materials such as paper, wool, metal, and polypropylene can be selected according to the use requirements and use scenarios.

[0040] The dust cap 124 can be made of the same material as the sound cone 123, making the appearance of the loudspeaker more coordinated and beautiful. The dust cap 124 is fixedly arranged at the center of the sound cone 123, and is used to prevent dust and other debris from entering the magnetic gap from the front of the sound cone 123, affecting the normal operation of the voice coil 122, thereby avoiding abnormal sound. The vibration assembly 12 is a prior art known to those skilled in the art, and will not be described further.

[0041] The magnetic circuit system 20 includes a magnetic circuit assembly 21 and an adapter 22 fixedly arranged on the side of the magnetic circuit assembly 21 facing the vibration system 10.

[0042] The magnetic circuit assembly 21 is used to generate and concentrate a magnetic field, thereby driving the voice coil 122 to move and drive the sound cone 123 to vibrate and emit sound. The magnetic circuit assembly 21 includes a T iron 211, a magnet 212 sleeved on the T iron 211, a dust core 213 located on one side of the magnet 212, and a copper sleeve 214 sleeved on the T iron 211.

[0043] The T iron 211 is mainly used to construct a magnetic circuit and guide magnetism. When the loudspeaker is powered on, the T iron 211 and the dust core 213 form a magnetic circuit to guide the magnetic field.

[0044] The magnet 212 is used to generate a magnetic field. When the loudspeaker is powered on, the current passes through the voice coil 122 to generate a magnetic field. The magnetic field of the magnet 212 interacts with the magnetic field generated by the voice coil 122, thereby driving the voice coil 122 to move up and down and driving the sound cone 123 to vibrate. The magnet 212 is sleeved on the iron column of the T iron 211 and is spaced apart from the iron column, thereby forming a magnetic gap between the iron column and the magnet 212, so as to arrange the voice coil 122 in the magnetic gap.

[0045] The dust core 213 is arranged on the side of the magnet 212 facing the vibration system 10, and is used to fix the magnet 212 and construct a magnetic circuit with the T iron 211 to guide the magnetic field.

[0046] The copper sleeve 214 is fixedly sleeved on the side of the iron column of the T-shaped iron facing the vibration system 10. When the vibration system 10 is assembled with the magnetic circuit system 20, one end of the voice coil 122 is sleeved outside the copper sleeve 214. Since the copper sleeve 214 has good self-lubricating performance, the arrangement of the copper sleeve 214 can increase the wear resistance of the T-shaped iron 211, thereby reducing the wear of the T-shaped iron and the voice coil 122.

[0047] The adapter frame 22 comprises an adapter frame body 221 fixedly arranged on the pot magnet 213, a plurality of adapter frame limiting protrusions 222 arranged at intervals on the side of the adapter frame body facing the vibration system 10, and a plurality of third fixing holes 223 arranged at intervals on the adapter frame body 221.

[0048] The adapter frame body 221 is fixed on the pot magnet 213 and is arranged in matching with the basin frame body 111. When the vibration system 10 is combined with the magnetic circuit system 20, the vibration system 10 is accommodated in the adapter frame body 221, and the voice coil 122 is sleeved outside the copper sleeve 214, thereby being combined into the loudspeaker.

[0049] The adapter frame limiting protrusions 222 are arranged in matching with the adapter frame positioning grooves 1114. When the vibration system 10 is accommodated in the adapter frame body 221, the adapter frame limiting protrusions 222 are inserted into the adapter frame positioning grooves 1114, thereby limiting the vibration system 10, so as to avoid displacement of the vibration system 10 along the circumferential direction of the adapter frame 22.

[0050] The third fixing holes 223 are arranged in correspondence with the first fixing holes 1115 and the second fixing holes 1123. When a nut is screwed through the first fixing holes 1115 into the second fixing holes 1123, the fixing ring 112 can be fixed with the basin frame 111. When a nut is screwed through the first fixing holes 1115 and the second fixing holes 1123 and the third fixing holes 223, the vibration system 10 can be fixed on the magnetic circuit system 20.

[0051] The vibration component 12 of the loudspeaker is combined with the yoke component 11 to form an independent vibration system 10 as a whole, and the adapter frame 22 is fixedly arranged on the magnetic circuit component 21. When assembled, the vibration system 10 is combined with the magnetic circuit system 20 through the adapter frame 11, so that the structure of the magnetic circuit component 21 and the vibration component 22 is not affected during disassembly of the vibration system 10 and the magnetic circuit system 20. Therefore, when the vibration system 10 or the magnetic circuit system 20 is damaged, the yoke component 11 and the adapter frame 22 are only needed to be removed, and the vibration system 10 or the magnetic circuit system 20 can be repaired or replaced.

[0052] Compared with the prior art, the vibration component 12 of the loudspeaker is mounted on the yoke component 11 to form an independent vibration system 10, and the adapter frame 22 matched with the yoke component 11 is arranged on the magnetic circuit system 20. The vibration system 10 and the magnetic circuit system 20 are connected together through the adapter frame 22, so that when the vibration system 10 and the magnetic circuit system 20 are disassembled, the yoke component 11 and the adapter frame 22 are only needed to be removed, and the structure of the magnetic circuit component 21 and the vibration component 22 is not affected. Therefore, when the vibration system 10 or the magnetic circuit system 20 is damaged, the vibration system 10 or the magnetic circuit system 20 can be repaired or replaced, the maintenance efficiency is improved, and the assembly time is saved.

[0053] The above is only a preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement in the spirit of the utility model is covered in the claim range of the utility model.
