Description

Technical Field

[0001] This invention relates to the field of vibrator technology, and more particularly to a vibrator with an easily controllable resonant response frequency. Background Technology

[0002] Vibroacoustic Therapy (VAT) is a method of "body-perceived music" that converts low-frequency signals (16Hz-150Hz) in music into mechanical vibrations through physical transduction. This dual stimulation of the mind and body can activate the brain's central nervous system in a short time, enabling people to quickly achieve high-quality physical and mental pleasure and relaxation. It effectively improves insomnia, anxiety, depression, psychosomatic disorders, and other adverse psychological states, and achieves a series of rehabilitation and health care effects.

[0003] The immersive experience of somatosensory music therapy is not solely due to auditory stimulation, but more importantly, to the direct transmission of sound wave vibrations through the body. However, the vibrators used in related technologies suffer from low vibration efficiency and electromagnetic radiation, hindering the widespread adoption of somatosensory music therapy.

[0004] Therefore, a haptic audio vibrator with intelligent resonant response value, high-efficiency energy conversion, and built-in electromagnetic wave shielding is designed by combining parameters before production. Addressing concerns about user experience and electromagnetic radiation is a technical problem that urgently needs to be solved by those skilled in the art.

[0005] Invention Design Content

[0006] This invention discloses a vibrator with easily controllable resonant response frequency to solve the problems existing in current vibrators. These problems include: 1. Vibrator failure due to delamination; 2. Insufficient vibration energy due to low quality of the vibration components; 3. Electromagnetic radiation caused by the partial plastic shell; 4. Technical problems such as the inability to select good material similar textures for trisection, and the frequent use of a certain hole position as the layout base point for quadrature, leading to uncoordinated operation of the spring and internal energy loss.

[0007] To solve the above problems, the present invention adopts the following technical solution: The oscillator with easily controllable resonant response frequency of the present invention includes a housing, a vibrating magnetic assembly, and a coil assembly, wherein the vibrating magnetic assembly and the coil assembly are both disposed within the housing; wherein: The vibrating magnetic assembly includes a bowl yoke, an inner yoke, a magnet, an outer yoke, a weight-adding ring, and a spring. The inner yoke, the magnet, and the outer yoke are sequentially arranged in the housing along the axial direction of the bowl yoke, and the inner yoke, the magnet, and the outer yoke are connected and fixed by a first screw connector. There is a magnetic circuit gap between the bowl yoke and the inner yoke. The coil assembly includes a coil frame and a coil. The coil frame is disposed within the magnetic circuit gap, and the coil is wound in the winding groove of the coil frame. When an alternating current is applied to the coil, the vibrating magnetic assembly can reciprocate along the axial direction of the coil frame.

[0008] Furthermore, the vibrating magnetic assembly also includes a weight-adding ring, which is connected and fixed to at least one of the bowl yoke, inner yoke, and outer yoke via a second screw connector.

[0009] Furthermore, the spring sheet includes an inner ring, an outer ring, and an elastic arm. The inner ring is connected and fixed to the vibrating magnetic assembly via a second screw connector, and the outer ring is connected and fixed to the housing via a third screw connector. Through the special design of the spring sheet and the feeding and layout design of the stamping die, the consistency of the material rolling texture of each of the four swing arms is controlled during mass production. The similarity of the metallographic structure after heat treatment results in a good normal distribution of the vibrator's response frequency. By adjusting the swing arm parameters and the mass of the weight-adding ring, a vibrator with the required response frequency can be innovatively designed.

[0010] The first end of the elastic arm is connected to the inner ring of the spring sheet, and the second end of the elastic arm is connected to the outer ring of the spring sheet. The elastic arms are evenly distributed along the radial direction of the spring sheet.

[0011] Furthermore, the first end and the second end of the elastic arm are located in different radial directions of the spring sheet.

[0012] Furthermore, the inner ring of the spring is connected between the bowl yoke and the outer yoke, or between the bowl yoke and the outer weight ring.

[0013] Furthermore, the inner ring of the spring and the outer ring of the spring are respectively provided with a first mounting hole and a first positioning hole.

[0014] Furthermore, the housing includes an upper cover plate, a lower cover plate, and a support positioning ring, the support positioning ring being located between the upper cover plate and the lower cover plate, and the upper cover plate, the support positioning ring, and the lower cover plate being connected and fixed by a third screw connector.

[0015] Furthermore, the support positioning ring is provided with a second mounting hole and a second positioning hole.

[0016] Furthermore, the edge of the upper cover plate or the lower cover plate is provided with radially extending mounting pins, and the mounting pins are provided with third mounting holes.

[0017] The technical solution adopted in this invention can achieve the following beneficial effects: The vibrator with easily controllable resonant response frequency disclosed in this application has an inner yoke, a magnet, and an outer yoke connected and fixed by a first screw connector. This connection is convenient, stable, and reliable, avoiding the poor reliability and long production cycle of traditional adhesive bonding. It can reduce the failure of the vibrating magnetic component due to delamination after long-term vibration. At the same time, the weight-adding ring inside the vibrating magnetic component increases the mass of the vibrating magnetic component, increases the vibration energy of the vibrating magnetic component, and improves the energy conversion efficiency of the audio signal. By adjusting the swing arm parameters and the mass of the weight-adding ring, the vibrator with the required response frequency can be innovatively designed. The mounting pin design solves the reliability problem of car seat installation. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The following is in conjunction with the appendix Figures 1 to 11 The high-efficiency vibrator provided in this application will be described in detail through specific embodiments and application scenarios.

[0024] Reference Figures 1-11 This application discloses an oscillator with an easily controllable resonant response frequency. The disclosed high-efficiency oscillator includes a housing 100, a vibrating magnetic component 200, and a coil component 300.

[0025] The housing 100 serves as the basic component of the high-efficiency vibrator, providing a mounting base for the vibrating magnetic assembly 200 and the coil assembly 300. Specifically, the housing 100 has a receiving space, within which both the vibrating magnetic assembly 200 and the coil assembly 300 are housed.

[0026] The vibrating magnetic assembly 200 includes a bowl yoke 210, an inner yoke 220, a magnet 230, an outer yoke 240, a spring 250, and a weight-adding ring (260). The bowl yoke 210 is a hollow cylindrical structure with one open end. The inner yoke 220 and the magnet 230 are located inside the bowl yoke 210. One polarity of the magnet 230 is in contact with the outer yoke 240, and the other polarity is in contact with the inner yoke 220. The outer yoke 240 is located outside the bowl yoke 210, and the outer yoke 240 is positioned away from the open end of the bowl yoke 210. In other words, the inner yoke 220, the magnet 230, the bowl yoke 210, and the outer yoke 240 are sequentially arranged within the housing 100 along the axis of the bowl yoke 210. (Refer to...) Figure 1 .

[0027] In this embodiment, the inner yoke 220, the bowl yoke 210, and the outer yoke 240 are connected and fixed by the first threaded connector 410 to form a vibration assembly. The tight connection between the inner yoke 220 and the magnet 230 and the bowl yoke 210 forms a magnetic circuit gap. The inner end of the spring piece 250 is connected to the vibration assembly, and the outer end of the spring piece 250 is connected to the housing 100.

[0028] The coil assembly 300 includes a coil frame 310 and a coil 320. The bottom wall of the coil frame 310 is connected to the housing 110. The coil 320 is pre-wound within the groove wall of the coil frame 310. The peripheral wall of the coil frame 310 is located within the magnetic circuit gap. (Refer to...) Figure 2 When an alternating current is applied to the coil 320, the magnetic poles of the coil 320 reciprocate, attracting or repelling the vibrating magnetic component 200, causing the vibrating magnetic component 200 to vibrate. The direction of movement of the vibrating magnetic component 200 is the axial direction of the coil frame 310, and the inner end of the spring piece 250 reciprocates, thereby driving the housing 100 to vibrate.

[0029] The high-efficiency vibrator disclosed in this application embodiment has an inner yoke 220, a magnet 230, and an outer yoke 240 connected and fixed by a first threaded connector 410. It features convenient and stable connection, avoiding the poor connection reliability and long production cycle of traditional adhesive bonding, and avoiding the delamination failure phenomenon that occurs during long-term vibration of the vibrating magnetic component.

[0030] The vibrating magnetic assembly 200 also includes a weight-adding ring 260, which is connected and fixed to at least one of the bowl yoke 210, inner yoke 220, and outer yoke 240 via a second screw connector 420. In an optional embodiment, refer to... Figure 5 The weight-adding ring 260 can be connected and fixed to the inner yoke 220 via the second screw connector 420 and located within the bowl yoke 210. In another optional embodiment, refer to... Figure 6The weight-adding ring 260 can be connected and fixed to the bowl yoke 210 via the second screw connector 420 and located within the bowl yoke 210. It is connected and fixed within the bowl yoke 210. In another optional embodiment, the weight-adding ring 260 can be connected and fixed to another weight-adding ring 260 via the second screw connector 420 passing through the bowl yoke 210 and the spring piece 250, as shown in the reference. Figure 7 .

[0031] In this embodiment, both the inner yoke 220 and the magnet 230 are annular disc-shaped structures. The diameter of the inner yoke 220 is larger than the diameter of the magnet 230, so that when the inner yoke 220 and the magnet 230 are assembled into a magnetic circuit, the bowl yoke 210, the inner yoke 220 and the magnet 230 need a necessary magnetic resistance space. The non-magnetic material weighting ring 260 is ingeniously set in this magnetic resistance space. The weighting ring 260 increases the mass of the vibrating magnetic component, achieving effective optimization of vibration energy per unit volume.

[0032] In this embodiment, the spring 250 includes an inner spring ring 251, an outer spring ring 252, and a plurality of elastic arms 253. The inner spring ring 251 is connected to the outer spring ring 252 via the elastic arms 253. The inner spring ring 251 is located between the bowl yoke 210 and the outer yoke 240, and the inner spring ring 251 can be connected and fixed to the bowl yoke 210 and the outer yoke 240 via the aforementioned second screw connector 420. The outer spring ring 252 is connected and fixed to the housing 100 via a third screw connector 430. Of course, the inner spring ring 251 can also be fixed between the bowl yoke 210 and the counterweight 260.

[0033] The first end of the elastic arm 253 is connected to the inner ring 251 of the spring sheet, and the second end of the elastic arm 253 is connected to the outer ring 252 of the spring sheet. The four elastic arms 253 are evenly distributed along the radial direction of the spring sheet 250, which ensures the uniformity of vibration transmission of the vibrating magnetic assembly 200 and realizes the stable operation of the vibrator.

[0034] In a further technical solution, the first end and the second end of the elastic arm 253 are located in different radial directions of the spring piece 250; that is, the first end of the elastic arm 235 extends along the circumference of the spring piece 250 and is connected to the outer ring 252 of the spring piece; with this setting, the resonant performance of the elastic arm 253 can be improved by adjusting the length of the elastic arm 253, thus avoiding the limitations of the spring piece resonance design in the past.

[0035] In further technical solutions, refer to Figure 8 , Figure 9The inner ring 251 and outer ring 252 of the spring are respectively provided with inner and outer layers of screw holes 254 and positioning holes 255, corresponding to screw hole 131 and positioning hole 132 on the support positioning ring; the screw holes and positioning holes between the bowl yoke 210 and the outer yoke 240 are fastened together with the second screw connector 420. In the housing 100, the positioning fit with the positioning hole 255 ensures the positional accuracy between parts; the fastening connection with the screw hole 254 improves the long-term reliability of the vibrator.

[0036] In this embodiment, the housing 100 includes an upper cover plate 110, a lower cover plate 120, and a support positioning ring 130. The support positioning ring 130 is located between the upper cover plate 110 and the lower cover plate 120. The upper cover plate 110, the support positioning ring 130, and the lower cover plate 120 are connected and fixed by a third screw connector 430. The upper cover plate 110, the support positioning ring 130, and the lower cover plate 120 define the accommodating space of the housing 100.

[0037] The coil frame 310 can be connected and fixed to the upper cover plate 110 by means of adhesive bonding, threaded connection, etc., and the outer ring 252 of the spring is located between the support positioning ring 130 and the lower cover plate 120. In this embodiment, the support positioning ring 130 is provided with screw holes 131 and positioning holes 132. The third screw connector 430 passes through the screw hole 131, and the positioning hole 132 can cooperate with the third positioning of the upper cover plate 110 and / or the lower cover plate 120 to ensure the assembly spatial position accuracy between the housing 100 and the spring.

[0038] In this embodiment, the upper cover plate 110, the lower cover plate 120 and the positioning support ring 130 are all structural components made of metal. With this configuration, the metal housing 100 has a shielding function, which can shield the electromagnetic waves generated by the coil 320 and avoid electromagnetic radiation hazards to the human body.

[0039] In further technical solutions, refer to Figure 10 The edge of the upper cover plate 110 or the lower cover plate 120 is provided with radially extended pins 121 and mounting holes 122 on the pins. The mounting holes 122 are used to install the high-efficiency vibrator. For example, the high-efficiency vibrator can be assembled onto a car seat by bolts or screws.
