[0002] At present, the working process of dynamic speakers is to convert electrical energy into vibration mechanical energy. When audio current passes through the voice coil, the voice coil will generate a magnetic field that changes with the law of current.

[0003] Dynamic speakers offer excellent mid-bass, low distortion, and high sound quality, making them the most widely used type of speaker in sound boxes and other devices. However, existing dynamic speakers require their voice coil leads to be soldered to terminals, a complex, time-consuming, and costly process. Furthermore, most dynamic speakers currently have a spring element, making them difficult to manufacture thinner.

[0031] Please refer to Figures 1 to 6 The utility model provides a dynamic loudspeaker without elastic wave and welding, including a diaphragm assembly and a magnetic circuit assembly connected to each other, and the diaphragm assembly includes:

[0032] A diaphragm 1 is provided with a plurality of conductive members 11;

[0033] The voice coil 2 is connected to the diaphragm 1 through the conductive member 11;

[0034] The first bracket 3 is provided with at least two wiring terminals 31 . The at least two wiring terminals 31 are connected to the voice coil 2 through the conductive member 11 .

[0035] In this embodiment, a spring-free, solder-free dynamic loudspeaker includes a diaphragm assembly and a magnetic circuit assembly interconnected with each other. The diaphragm assembly includes a diaphragm 1, with multiple conductive members 11 disposed around each side of the diaphragm 1. The diaphragm 1 is connected to a voice coil 2 via the conductive members 11 disposed thereon. In existing dynamic loudspeakers, the voice coil is soldered to a terminal block via leads, resulting in a complex, time-consuming, and costly manufacturing process. However, in this embodiment of the present application, the voice coil 2 is connected to the terminal block 31 via the conductive members 11. This eliminates the need for precise soldering of the voice coil 2 leads to the terminal block 31. Instead, the voice coil 2 and the terminal block 31 are directly connected via the conductive members 11, simplifying the loudspeaker manufacturing process and reducing manufacturing costs. At least two terminal blocks 31 are provided, and at least two of the terminal blocks 31 are disposed on the first bracket 3. In this embodiment, four conductive members 11 are provided; the number of conductive members 11 is not limited and may be determined based on actual production requirements.

[0036] Currently, most dynamic speakers have elastic waves. Setting elastic waves in the speaker will make the overall thickness of the speaker thicker. The elastic waves can play a positioning role. The conductive member 11 in the present application fixes the voice coil 2 on the diaphragm 1, thereby playing a positioning role similar to that of the elastic waves, thereby making the overall thickness of the speaker thinner; and the conductive member 11 can also connect the voice coil 2 and the terminal 31, thereby playing the role of a silk thread, where the silk thread is a wire used to connect the voice coil 2 and the terminal 31.

[0037] The conductive member 11 is made of a flexible conductive material, so that it can be attached to the diaphragm 1 and act as a brocade thread to connect the voice coil 2 and the terminal 31. In the embodiment of the present application, the conductive member 11 is specifically a flexible conductive sheet.

[0038] Furthermore, the diaphragm 1 is provided with a diaphragm surround 12 on all four sides, and the plurality of conductive members 11 extend along the diaphragm surround 12 to all four sides of the diaphragm 1. That is, the plurality of conductive members 11 are provided on all four sides of the diaphragm 1, and the conductive members 11 are also extended from the positions on all four sides of the diaphragm 1 where the diaphragm surround 12 is provided.

[0039] Furthermore, the voice coil wire of the voice coil 2 is bonded to the conductive member 11 via conductive adhesive. That is, the voice coil wire on the voice coil 2 is directly bonded to the conductive member 11 bonded to the diaphragm 1 via conductive adhesive, eliminating the need for soldering. The conductive adhesive bonding method allows for automated production, maintains product consistency, and improves production efficiency.

[0040] Furthermore, at least two terminals 31 are bonded to the conductive member 11 with conductive adhesive to connect to the voice coil 2. In other words, the terminals 31 are directly bonded to the conductive member 11 with conductive adhesive, eliminating the need for soldering. This bonding method facilitates automated production, maintains product consistency, and improves production efficiency.

[0041] Furthermore, the connection terminal 31 is exposed on the first bracket 3 and is bonded to the conductive member 11 extending around the diaphragm 1 through conductive glue. The side of the first bracket 3 where the connection terminal 31 is provided is bonded to the diaphragm 1 .

[0042] In this embodiment, the terminal block 31 is directly cast in the first bracket 3, but the metal part of the terminal block 31 is exposed outside the first bracket 3, so that the metal part of the terminal block 31 can be directly bonded to the conductive member 11 around the diaphragm 1 through conductive glue, thereby connecting the terminal block 31 and the conductive member 11; and the side of the first bracket 3 on which the terminal block 31 is provided is also connected to the diaphragm 1 through glue, so that the diaphragm 1 provided with the voice coil 2 can be bonded to the first bracket 3, thereby eliminating the need for welding connection. The combination of conductive glue and glue bonding can adapt to automated production, maintain product consistency, and improve production efficiency.

[0043] Furthermore, a cover 4 is connected to a side of the diaphragm 1 away from the first bracket 3 .

[0044] In this embodiment, a voice coil 2 is provided on one side of the diaphragm 1 and connected to the first bracket 3, and a cover 4 is connected to the other side. The cover 4 is mainly used to press the four sides of the diaphragm 1 to prevent the diaphragm 1 from debonding.

[0045] Furthermore, the magnetic circuit assembly includes a U-iron 5, a magnetic part 6 and a second bracket 7. The magnetic part 6 is embedded in the U-iron 5. The side of the voice coil 2 away from the diaphragm 1 is arranged between the magnetic part 6 and the U-iron 5. The U-iron 5 is clamped and connected to the second bracket 7. The second bracket 7 is also connected to the first bracket 3.

[0046] In this embodiment, the magnetic circuit assembly includes a U-iron 5, a magnetic member 6, and a second bracket 7. The U-iron 5 is provided with a groove, and the magnetic member 6 is embedded in the groove of the U-iron 5. Specifically, one side of the second bracket 7 is connected to the U-iron 5 by a clamping connection, and the other side is also connected to the first bracket 3 by a clamping connection, thereby connecting the magnetic circuit assembly to the diaphragm assembly. Among them, one side of the voice coil 2 is fixedly connected to the diaphragm 1, and the other side is arranged between the magnetic member 6 and the U-iron 5. The magnetic member 6 in this embodiment is specifically a magnet. The specific type of the magnetic member 6 is not limited here and is set according to actual production requirements.

[0047] Furthermore, a plurality of protrusions are provided on the first bracket 3, and a plurality of limiting grooves adapted to the protrusions are provided on the second bracket 7. The first bracket 3 and the second bracket 7 are adapted and connected through the plurality of protrusions and the limiting grooves.

[0048] In this embodiment, a plurality of protrusions are provided on the first bracket 3, and a plurality of limiting grooves are provided on the second bracket 7. The protrusions on the first bracket 3 are adapted to the limiting grooves on the second bracket 7, so that the first bracket 3 can be adapted to be connected with the second bracket 7 through the protrusions and the limiting grooves, thereby enabling the magnetic circuit assembly and the diaphragm assembly to be adapted to be connected.

[0049] Furthermore, the dynamic speaker has a thickness range of 2.5 mm to 3.5 mm and a width range of 6 mm to 7 mm.

[0050] The dynamic speaker in the embodiment of the present application has a simple and compact structure and an ultra-thin appearance through the above-mentioned arrangement, and is very suitable for miniaturized products. Specifically, the thickness range of the dynamic speaker is 2.5mm-3.5mm. In the present embodiment, the thickness of the dynamic speaker is 3mm. The specific thickness is not limited here and is set according to actual production needs; the width range of the dynamic speaker is 6mm-7mm. The width of the dynamic speaker in the present embodiment is 6.8mm. The specific width is not limited here and is set according to actual production needs.
