[0002] The voice coil massager is a common massage device, which is often used to massage various parts of the human body. When the voice coil is powered on, the voice coil massager inputs an audio signal to the voice coil. The alternating magnetic field generated by the voice coil drives the massage head set on the voice coil seat to move through the electromagnetic force, and deforms the vibrating reed. When the voice coil is powered off, the vibrating reed rebounds and drives the voice coil seat to reset, thereby achieving the massage function.

[0003] In the existing voice coil massager, a wire hole is opened in the axial direction of the magnetic yoke, and the wire of the voice coil passes through the wire hole to connect to the power supply. Since a hole needs to be opened on the magnetic yoke, the processing cost is high, the installation is inconvenient, and the insulation of the connected wire is high, which sacrifices the durability of some wires. When the voice coil massager vibrates, the friction between the wire and the magnetic yoke will also increase, affecting the service life of the wire. Summary of the invention

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] This embodiment discloses a voice coil massager, referring to Figures 1 to 4 , which includes a yoke 100, a magnet block 200, a voice coil seat 300, a vibration reed 400, a massage head 500, a fixed bracket 600 and a wire adapter plate 700. The magnet block 200 is fixed in the yoke 100, and the voice coil seat 300 is sleeved outside the magnet block 200. A voice coil 330 is wound around the outer circumference of the voice coil seat 300, and the yoke 100 is sleeved outside the voice coil seat 300. The massage head 500 is fixed to the voice coil seat 300 and extends out of the yoke 100, the vibration reed 400 is fixedly connected to the voice coil seat 300, and the outer edge of the vibration reed 400 is fixed above the end of the yoke 100. The fixed bracket 600 is fixedly connected above the yoke 100 and connected to the vibration reed 400.

[0029] When the voice coil 330 is powered, under the superposition of the magnetic fields of the voice coil 330 and the magnet block 200, the voice coil seat 300 can drive the massage head 500 to slide along the axial direction of the yoke 100, and cause the vibration reed 400 to deform and accumulate elastic energy. When the voice coil 330 is powered off, the vibration reed 400 releases elastic energy, driving the voice coil seat 300 and the massage head 500 to reset. By applying an alternating current to the voice coil 330, the voice coil seat 300 and the massage head 500 are driven to vibrate back and forth, thereby realizing the massage function.

[0030] In this embodiment, the yoke 100 is a cylindrical member. The upper end of the yoke 100 is open, and the lower end of the yoke 100 has a closed bottom wall. The magnet block 200 is fixed to the bottom wall of the yoke 100. A portion of the voice coil seat 300 is located in the yoke 100, and a portion of the voice coil seat 300 can extend out of the upper end opening of the yoke 100 and be connected to the massage head 500 to drive the massage head 500 to reciprocate.

[0031] The magnet block 200 is cylindrical so that the magnetic field of the magnet block 200 is relatively uniform. The magnet block 200 can be fixed to the yoke 100 by bonding, bolting, clamping, etc. In this embodiment, the magnet block 200 is fixed to the bottom wall of the yoke 100 by bonding, and the magnet block 200 is coaxially arranged with the yoke 100. The voice coil seat 300 is cylindrical, and the voice coil seat 300 is sleeved outside the magnet block 200 and coaxially arranged with the magnet block 200. One end of the voice coil seat 300 away from the magnet block 200 is connected to the massage head 500, and the voice coil 330 is sleeved outside the voice coil seat 300.

[0032] A circuit board 310 is provided on the side of the voice coil seat 300 away from the magnet block 200, and the voice coil 330 is electrically connected to the circuit board 310 through a connecting wire 340. The circuit board 310 leads out another section of the connecting wire 340 to connect with the wire adapter board 700. A support platform 320 is protrudingly provided in the middle of the side of the voice coil seat 300 away from the magnet block 200, and the vibration reed 400 is connected to the support platform 320. The support platform 320 supports the vibration reed 400 away from the voice coil seat 300 to prevent the vibration reed 400 from interfering with the circuit board 310 or the voice coil seat 300.

[0033] The massage head 500 is fixed to the side of the support platform 320 away from the voice coil seat 300 and pressed on the vibration reed 400, thereby ensuring the concentricity of the massage head 500 and the voice coil seat 300. At the same time, the voice coil seat 300 limits the vibration reed 400, making the vibration reed 400 more reliably installed.

[0034] Reference Figures 3 to 5 The vibration reed 400 includes an elastic support leg 410 and a support plate 420, and the elastic support leg 410 is connected between the yoke 100 and the support plate 420. The support plate 420 is fixed on the support platform 320 of the voice coil seat 300 and is located below the massage head 500. A plurality of elastic support legs 410 are provided and distributed along the circumference of the support plate 420, and the plurality of elastic support legs 410 and the support plate 420 are located in the same plane.

[0035] In this embodiment, four elastic legs 410 are arranged at intervals along the circumference of the support plate 420, and the portion of each elastic leg 410 away from the support plate 420 is fixedly connected to the yoke 100 or the fixed bracket 600. The elastic legs 410 are arc-shaped, so that the elastic legs 410 can withstand greater vibration force without being easily broken. A plurality of stress holes 421 are provided on the support plate 420 to release the internal stress of the vibration reed 400 during vibration, so that the support plate 420 can withstand greater vibration force.

[0036] Reference Figures 1 to 5The fixing bracket 600 is detachably connected to the yoke 100. The fixing bracket 600 is provided with an escape hole 610 for the massage head 500 to pass through, so that the massage head 500 can reciprocate to perform massage. A mounting groove 620 is provided on the side of the fixing bracket 600, and the mounting groove 620 passes through the side wall of the fixing bracket 600, and the wire adapter plate 700 is installed in the mounting groove 620.

[0037] In this embodiment, the fixed bracket 600 is made of metal, which has a relatively high density and a better effect in absorbing low-frequency vibrations. At the same time, the metal fixings can support the vibration reed 400 above the yoke 100, and can also block the top of the voice coil 330 to reduce the falling of dust. The fixed bracket 600 is fixed to the yoke 100 to play the role of fixing, dustproofing and vibration absorption.

[0038] The side of the installation groove 620 facing the yoke 100 is open, and the base 710 is fixed to the side of the yoke 100 facing the installation groove 620 .

[0039] Specifically, the wire adapter plate 700 includes a base 710 and a connection terminal 720. The base 710 is located in the mounting groove 620 and fixed on the yoke 100. The connection terminal 720 is fixed to the base 710 and extends out of the mounting groove 620. One end of the connection terminal 720 located in the mounting groove 620 is connected to the circuit board 310 through the connecting wire 340, and one end of the connection terminal extending out of the mounting groove 620 is connected to the external power supply, thereby supplying power to the voice coil 330, thereby making it unnecessary for the connecting wire 340 to pass through the yoke 100, reducing the insulation requirements of the connecting wire 340, so that the connecting wire 340 can use fold-resistant cotton thread, improving the wear resistance of the connecting wire 340, and at the same time, there is no need to open a hole on the yoke 100 for the connecting wire 340 to pass through, which facilitates the manufacture of the yoke 100.

[0040] The outer side of the base 710 is connected to a flange 711 which is in an arc shape that fits the outer periphery of the yoke 100 . The flange 711 is bent away from the fixing bracket 600 and fits the outer periphery of the yoke 100 , thereby improving the connection strength between the base 710 and the yoke 100 .

[0041] A plurality of connecting posts 800 are connected to the side of the yoke 100 facing the fixed bracket 600. The connecting posts 800 extend in the direction away from the yoke 100 along the axial direction of the yoke 100, and the outer ends of the elastic legs 410 are fixedly connected to the connecting posts 800. One end of the elastic legs 410 away from the support plate 420 is fixed to the side of the connecting posts 800 away from the yoke 100, so that there is a gap between the vibration reed 400 and the end of the yoke 100, which facilitates the deformation of the vibration reed 400, thereby meeting the reciprocating vibration stroke of the voice coil seat 300 and the massage head 500, and reducing the axial length of the yoke 100, saving the cost of the yoke 100.

[0042] In this embodiment, the number of connecting posts 800 is the same as the number of elastic legs 410, and the elastic legs 410 are connected to the connecting posts 800 in a one-to-one correspondence. Specifically, in this embodiment, there are four connecting posts 800 and four elastic legs 410, and the four connecting posts 800 are evenly arranged along the circumference of the yoke 100.

[0043] In this embodiment, the fixed bracket 600 is provided with a clearance groove 630, and the connecting columns 800 are installed in the clearance groove 630 one by one, thereby making it difficult for the setting of the fixed bracket 600 to interfere with the connecting columns 800, making the structure of the voice coil massager 1000 more compact and reasonable.

[0044] In this embodiment, the number of the clearance grooves 630 is the same as the number of the connecting pillars 800. The two clearance grooves 630 close to the installation groove 620 are communicated with the installation groove 620.

[0045] In this embodiment, the connecting column 800 is fixedly connected to the fixing bracket 600 via a connecting bolt 900 , and the connecting bolt 900 passes through the fixing bracket 600 , the vibration reed 400 , and the connecting column 800 at the same time.

[0046] Specifically, the fixed bracket 600 is provided with a first connection hole 640 at the portion facing the clearance groove 630, the outer end of the elastic foot 410 is provided with a second connection hole 411, the connecting column 800 is provided with a third connection hole 810 that penetrates the connecting column 800 in the axial direction, and the yoke 100 is provided with a threaded hole 110. The first connection hole 640, the second connection hole 411, the third connection hole 810 and the threaded hole 110 are aligned and connected with each other, and the connecting bolt 900 passes through the first connection hole 640, the second connection hole 411 and the third connection hole 810 in sequence and is threadedly matched with the threaded hole 110. Therefore, the connecting bolt 900 is used to simultaneously connect the fixed bracket 600, the vibration reed 400, the connecting column 800 and the yoke 100, so that the voice coil massager 1000 is easy to disassemble and assemble.

[0047] A buffer guide sleeve 650 is provided on the fixed bracket 600, and the buffer guide sleeve 650 is coaxially fixed in the avoidance hole 610, and the massage head 500 is movably inserted in the buffer guide sleeve 650. The inner hole of the buffer guide sleeve 650 guides the movement of the massage head 500, making the massage head 500 more stable when moving. At the same time, the buffer guide sleeve 650 buffers the massage head 500 and the fixed bracket 600 when the massage head 500 reciprocates for massage, thereby reducing the vibration impact brought to the voice coil massager 1000 by the massage head 500 when moving.

[0048] Among them, a circle of positioning ring part 611 is protruding inward on the inner circumference of the avoidance hole 610, and a circle of annular groove 651 is formed on the outer circumference of the buffer guide sleeve 650. The positioning ring part 611 is inserted and matched in the annular groove 651, thereby facilitating the installation of the buffer guide sleeve 650 and making the buffer guide sleeve 650 and the avoidance hole 610 match stably.

[0049] In this embodiment, the buffer guide sleeve 650 is made of silicone. The flexible silicone material enables the buffer guide sleeve 650 to better buffer the vibration of the massage head 500, reduce the friction of the massage head 500, and facilitate the connection between the buffer guide sleeve 650 and the fixed bracket 600.
