The embodiment of the application provides a wearable equipment, and it utilizes solid transaudient, through 2 human skins of vibration part vibration, promotes the transmission efficiency of vibration through special treatment, makes more transmission of acoustic energy to people's ear periosteum department to the acoustic pressure level of transaudient has been increased.

Specifically, referring to fig. 1 to 5, an embodiment of the present application provides a wearable device, including: a wearing body 1 (partial structure in the figure), a vibration member 2, and an expansion member 3. The wearing body 1 can be arranged along the circumference of the user limb when the wearable device is worn, and a closed wearing space is formed between the wearable device and the limb of the user. For example, the wearing body 1 may have a ring shape, and a closed wearing space is formed in the wearing body 1. The vibration part 2 is provided on the wearing body 1 at a side near the bottom surface thereof, and the expansion part 3 is provided on the bottom surface and connected to the vibration part 2, thereby facilitating contact with the skin of the human body.

The expansion element 3 has an expanded state and a recovered state. Under the inflation state, the volume of inflation part 3 grow, and then dwindle the wearing space for wearable equipment and the inseparabler contact of person's limbs of wearing, make the last vibration of vibration part 2 of wearable equipment can be more abundant transmit person's limbs of wearing, simultaneously because inflation part compresses tightly behind the user's limbs, make the muscle of limbs relevant position tighten up, more press close to human skeleton 7, thereby the sound wave arouses cochlea resonance through human skeleton 7 better transmission to human cochlea, forms the sense of hearing. This application replaces traditional air transaudient through bone conduction transaudient, has formed the solid transaudient, has reduced the sound leakage risk, has promoted user experience.

fifth, the method comprises the following steps: the expansion member 3 has good deformation characteristics and is not easily broken after being bent and expanded.

In order to satisfy the above requirements, the expansion member 3 may be made of a shape memory alloy.

Wearable equipment uses intelligent wrist-watch as an example, and when the hand contact people face bone that the user wore the wrist-watch, the vibration of sound wave can be followed on hand and transmitted to face, and then conduct on the periosteum of people's ear, make the sound of hearing that the user can be clear.

The vibrating component 2 of the wearable device provided by the embodiment of the application can adopt different vibration principles, and the vibration structures corresponding to different vibration principles are different. The general vibration member 2 may be classified into a moving-iron type vibration member and a piezoelectric type vibration member. Taking a moving-iron type vibration component as an example:

referring to fig. 1 to 3, the vibration part 2 includes a vibrator 21 and a diaphragm 22, the diaphragm 22 is connected to the vibrator 21 through a buffer 23, and the vibrator 21 includes a vibrator case 211, a U-iron 212, a magnet 213, and a coil 214. The vibrator housing 211 may be connected to a case of the wearable device wearing body 1, the coil 214 is fixedly connected to the inside of the vibrator housing 211, the magnet 213 is disposed at the middle of the U-iron 212, the magnet 213 is accommodated in a space surrounded by the coil 214, the diaphragm 22 is connected to the U-iron 212 through the buffer 23, and the expansion member 3 may be directly connected to the diaphragm 22.

The operation of the vibrating member 2 is as follows:

when the coil 214 is energized with an alternating current, the magnet 213 and the U-iron 212 form a self-closing stable magnetic field, so that the U-iron 212 pushes the buffer 23 to generate vibration and further pushes the diaphragm 22 to vibrate under the action of the lorentz force. The buffer member 23 serves as a buffer function, and prevents rigid contact between the diaphragm 22 and the U-iron 212, and when the expansion member 3 is attached to the diaphragm 22 and located on the bottom surface (the surface facing the wearing space) of the wearing body 1, the diaphragm 22 vibrates and transmits the vibration to the human skin tissue 6 through the expansion member 3.

When vibration part 2 is piezoelectric type vibration part 2, vibration part 2 includes the piezoelectric patches, and expanding element 3 can direct connection in this piezoelectric patches, and wearable equipment's electric control part passes through AC circuit 9 to be connected in this piezoelectric patches, and when AC circuit 9 switched on, the piezoelectric patches can take place the vibration to drive expanding element 3 vibration.

In a possible embodiment, as shown in figure 4, the wearable device comprises a power supply circuit 8 connected to the expansion member 3; in a state where the power supply circuit 8 is on, the expansion member 3 is in the expanded state; in a state where the power supply circuit 8 is disconnected, the expansion member 3 is in the recovery state.

In this embodiment, the wearable device comprises a control chip 5, said control chip 5 being connected to said vibration member 2 via an alternating current circuit 9, said control chip 5 being connected to the expansion member 3 via a power supply circuit 8. When wearable equipment received the vibration instruction, control chip 5 switched on simultaneously power supply circuit 8 and alternating current circuit 9, inflation part 3 circular telegram back, begin deformation inflation grow, also reduced the wearing space for the limbs with wear main part 1 in close contact with more, the vibration on the vibration part 2 can be more abundant transmit to the limbs like this. Meanwhile, the body 1 is worn to compress the limbs so that the muscles of the corresponding parts of the limbs are tightened and are closer to the skeleton 7 of the human body, and sound waves can be better transmitted into the human body. When the vibration process is about to end, the control chip 5 disconnects the power supply circuit 8 and the alternating current circuit 9, so that the expansion component 3 recovers deformation, the wearing space becomes large, and the wearing body 1 relaxes limbs.

Referring to fig. 5, in a possible embodiment, the wearable device comprises a heating component 4; the heating member 4 is connected between the vibration member 2 and the expansion member 3; when the heating means 4 is heated, the expansion means 3 is in the expanded state.

In this embodiment, the wearable device comprises a control chip 5, said control chip 5 being connected to said vibrating member 2 via an alternating current circuit 9, said control chip 5 being connected to the heating member 4 via a power supply circuit 8. When wearable equipment receives the vibration instruction, control chip 5 switches on simultaneously power supply circuit 8 and alternating current circuit 9, heating element 4 circular telegram back, begin to generate heat, and expanding element 3 receives the thermal stimulation back, begins the deformation inflation, has reduced wear the space for the limbs with wear main part 1 inseparable contact more, wear vibration on main part 1 like this can be more abundant transmission to the limbs, owing to wear main part 1 and compress tightly the limbs and make the corresponding position muscle of limbs tighten up, more press close to human skeleton 7, transmission that the sound wave can be better is inside human body. When the vibration process is about to end, the control chip 5 disconnects the power supply circuit 8 and the alternating current circuit 9, the heating component 4 stops heating, the expansion component 3 cools, the deformation starts to recover, the wearing space becomes large, and the limbs are relaxed.

Due to the presence of the expansion element 3, the vibrations are less lost during transmission and can be transmitted directly to the bone 7 of the wearer. For example, when the wearable device is worn on a limb, and the wearer touches the face, particularly the skeletal portion of the cheek, with a finger or a dorsal portion of the hand, such as the act of holding the head against the back of the hand, or pressing the skeletal portion against a position near the ear with a finger, vibrations may be transmitted from the hand to the face, which in turn are transmitted through the skeletal portion of the cheek of the face to the cochlea causing cochlear resonance, resulting in auditory sensation. It is conceivable that the vibration of the vibration member 2 is consumed by the human skin tissue 6 and the effect of sound transmission is seriously deteriorated without the expansion member 3 serving as a coupling medium.

In one possible embodiment, the heating element 4 comprises a resistive layer disposed on the surface of the vibrating plate 22, to which the control chip 5 is connected via the power supply circuit 8. When the resistive layer is energized, heat is generated.

In a possible embodiment, the wearing body 1 is provided with a mounting portion on a side surface thereof located in the wearing space, the vibration member 2 is mounted on the mounting portion, and the expansion member 3 covers the vibration member 2. When the wearable device is worn by a wearer, the expansion part 3 of the wearable device contacts with the skin of the human body. The mounting portion may be specifically a mounting groove 11, and the expansion member 3 is disposed in the mounting groove 11. The expansion part 3 is embedded in the mounting groove 11, and the structure is firm. When the expansion part 3 expands, the expansion part 3 extends out of the mounting groove 11 to press the skin of the limb of the wearer, and when the expansion part 3 deforms and recovers, the expansion part 3 retracts into the mounting groove 11 to relax the limb of the wearer.

In a possible embodiment, the expansion means 3 are in the form of a sheet; alternatively, the expansion member 3 may be annular.

In this embodiment, the expansion element 3 may be a sheet-like body covering the surface of the vibration plate 22 so as to be sufficiently in contact with the limb of the wearer. The expansion member 3 may be ring-shaped and attached to the surface of the diaphragm 22. Of course, the expansion member 3 may have other shapes, and is not limited thereto.
