[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-Figure 7 A skin patch microphone structure includes a wearable ring, wherein the wearable ring is provided with:

[0031] A connecting structure, the connecting structure is used to wear the wearing ring on the neck of a human body;

[0032] The microphone structure is used to collect sound signals emitted from the human neck.

[0033] The wearable ring includes a neckband 1, which is made of skin-friendly silicone material and is integrally formed. A plurality of inclined grooves 15 are provided on the neckband 1.

[0034] The neckband 1 made of skin-friendly silicone material can reduce the discomfort of the elderly when wearing this patch microphone when it fits the neck of the elderly. The inclined groove 15 is provided to assist the neckband 1 in perspiration at the skin where it fits. Since it is necessary to ensure the fixing effect of the microphone structure, the neckband 1 is completely in contact with the skin when tied around the elderly's neck. Opening the inclined groove 15 can create a gap between the neckband 1 and the elderly's skin in some areas, which is conducive to perspiration and sweat evaporation, and improves the comfort of the elderly when wearing it.

[0035] The connecting structure includes a card plate 2 fixedly connected to one end of the neck strap 1, and the end of the neck strap 1 away from the card plate 2 is fixedly connected to a gusset plate 3, elastic sheets 4 are fixedly connected to both sides of the card plate 2, a recessed groove matching the card plate 2 is provided on the gusset plate 3, and a clearance opening 5 matching the elastic sheet 4 is provided on both sides of the recessed groove, a card slot 10 is provided on the side of the gusset plate 3 away from the card plate 2, one of the side walls of the card slot 10 is rotatably connected to a pressure rod 11, and a plurality of pointed cones 12 are fixedly connected to the bottom of the pressure rod 11, the pointed cone 12 is inserted into the neck strap 1, and an elastic card 13 is fixedly connected to the top of the other side wall of the card slot 10, the elastic card 13 is integrally formed of an elastic metal material (such as a stainless steel sheet), and the elastic card 13 is arranged to resist the pressure rod 11, a clearance groove is provided on the lower surface of the elastic card 13, and a connecting groove 14 is provided on the side of the pressure rod 11 away from the pointed cone 12;

[0036] In this design, the card plate 2 cooperates with the gusset plate 3. When the caregiver helps the elderly wear the neckband 1, he or she only needs to insert the card plate 2 into the sink, and then the elastic piece 4 extends from the clearance opening 5 to achieve the card connection between the card plate 2 and the gusset plate 3, thereby completing the fixation of the neckband 1.

[0037] The neck strap 1 is then tightened and the buckle plate 3 is fixed to the neck strap 1. The buckle plate 3 and the neck strap 1 are fixed to the neck strap 1. When the buckle plate 3 and the neck strap 1 are worn for the first time, the user cuts the neck strap 1 according to the neck circumference of the elderly, and then puts the end of the neck strap 1 into the card slot 10. Then, the pressure rod 11 is rotated to press the pressure rod 11 on the neck strap 1, and the sharp cone 12 is inserted into the neck strap 1. In the process of rotating the pressure rod 11, the elastic card 13 is pushed aside to make way for the pressure rod 11 until the pressure rod 11 is completely pressed on the neck strap 1. Then, the elastic card 13 returns to its initial position under the action of its own elastic force, and the elastic card 13 presses on the pressure rod 11 so that the pressure rod 11 cannot rotate, and finally the buckle plate 3 and the neck strap 1 are fixed. The setting of the making way slot and the connecting slot 14 is to improve the cooperation effect of the elastic card 13 and the pressure rod 11. Since the neck circumference of the elderly will not change in the short term and the neck strap 1 needs to be adjusted, it is prioritized to ensure the tightness of the connection between the buckle plate 3 and the neck strap 1.

[0038] Furthermore, the microphone structure includes a connection shell 6 fixedly connected to the neckband 1, and a patch microphone 7 is fixedly connected inside the connection shell 6;

[0039] Among them, the patch microphone 7 can adopt a silicon microphone based on MEMS technology, or an IMU patch sensor can be used as an alternative, and the IMU patch sensor is used to sense vibration to collect sound.

[0040] The connecting shell 6 has an opening on its side wall near the patch microphone 7, and a diaphragm 17 is provided in the opening. The connecting shell 6 is glued and fixed to the neckband 1, and the connecting shell 6 is arc-shaped.

[0041] In this design, the connecting shell 6 is combined with the diaphragm 17 (a polyurethane film is used in this embodiment), which can not only utilize the diaphragm 17 to reduce the attenuation during sound wave transmission, but also ensure the sealing of the connecting shell 6, preventing sweat from directly contacting the patch microphone 7, causing the patch microphone 7 to be corroded by sweat. While ensuring the sound collection effect of the patch microphone 7, the waterproof level of the microphone structure (reaching IP54, sweat and rain proof) is guaranteed to meet actual use requirements, and the curved connecting shell 6 can better fit the neck skin of the elderly.

[0042] Furthermore, the electronic control module includes a mounting shell 8 fixedly connected to the card board 2, a battery slot is provided in the mounting shell 8, and a button battery 9 is provided in the battery slot. A wireless communication module is also provided in the mounting shell 8, and the button battery 9 is electrically connected to the wireless communication module and the patch microphone 7 through a wire. The wire is located in the neckband 1. The mounting shell 8 is rotatably connected to the side wall near the battery slot, and the pressure plate 16 is arranged to abut against the button battery 9;

[0043] Based on the above design, the mounting shell 8 is set in the card board 2. After the card board 2 is inserted into the buckle plate 3, the inner wall of the sink can be used to press on the button battery 9, so that the button battery 9 is fixed in the battery slot. The wireless communication module is set to transmit the information received by the patch microphone 7 through a wireless signal, and the sound is analyzed and the corresponding reminder and warning functions are realized in combination with the APP adapted to this microphone structure. This microphone structure is only an information collection device and does not need to process the electrical signal converted from the sound. Of course, in another embodiment, a control processor can be set in the mounting shell 8. After the data collected by the microphone structure is processed, it is sent through the wireless communication module. Whether to use the control processor depends on the communication protocol. For example, if it is not sent directly through the control processor, FM transmission can be used, and through the control processor, the analog signal output by the microphone 7 is transmitted through the built-in ADC It is converted into a digital audio stream and then transmitted (using a communication module such as a 4G module. The specific communication module used also depends on the communication protocol). This is a well-known technology and will not be described in detail here. The pressure plate 16 is provided to improve the fixing effect of the button battery 9, and to protect the button battery 9 when the elderly need to remove the microphone structure for a bath or similar behavior.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
