Description

Technical Field

[0001] The present invention relates to the field of Bluetooth earphones, and further to an ear-clip earphone capable of health detection. Background Art

[0002] Compared with traditional Bluetooth headsets, clip-on earphones do not enter the ears and are more comfortable to wear. When wearing them, you can listen to the sound of the earphones and receive external sound feedback, which is very suitable for outdoor sports and other scenarios.

[0036] refer to Figures 1 to 3 The present invention provides an earphone capable of health detection, comprising an earphone body 1 and a clamping portion 2, wherein the clamping portion 2 is mounted at the end of the earphone body 1, and the clamping portion 2 and the earphone body 1 form a clamping space 21, and a health detection component 3 is also provided on the clamping portion 2, and the health detection component 3 comprises an optical fiber 31, an optical sensor 32 and a window 33, and an optical signal of the optical sensor 32 is transmitted to the window 33 through the optical fiber 31 and then irradiated onto human tissue, and the reflected light of the human tissue is then received by the optical sensor 32 through the window 33 and the optical fiber 31.

[0037] In this embodiment, the clamping portion 2 and the earphone body 1 form a clamping space 21, and an optical sensor 32 is provided in the clamping portion 2. The light signal of the optical sensor 32 is transmitted to the window 33 through the optical fiber 31 and then irradiated onto the human tissue. The reflected light of the human tissue is then received by the optical sensor 32 through the window 33 and the optical fiber 31, so that the clamping portion 2 can be used to clamp the ear and realize the health detection function, and the size of the ear-clip earphone with health detection can be miniaturized.

[0038] Specifically, the health detection component 3 can detect health indicators such as heart rate and blood oxygen. Figure 2 and Figure 3 The health detection component 3 includes an optical fiber 31, an optical sensor 32 and a window 33. The optical sensor 32 is used to output optical signals, the optical fiber 31 is used to transmit optical signals, and the window 33 is used to irradiate the optical signal in the optical fiber 31 onto the back of the human ear, and then the optical signal is reflected back and transmitted to the optical sensor 32 again through the optical fiber 31. The key structure inside the optical sensor 32 is a diode for emitting light and an optical receiver. The principle inside the optical sensor 32 is that the diode can emit green light or red light to irradiate human tissue, and then the optical signal reflected back by the light is received by the optical receiver, and then the optical signal is fed back to the chip for processing and calculation to obtain the detection result. The health detection component 3 is arranged inside the clamping part 2, and there is no need to occupy a large amount of the internal space of the earphone body 1. The clamping part 2 can not only clamp the ear, but also perform health detection, so that the volume of the clip-on earphone with a small space can be reduced, providing a basis for the miniaturization design of the clip-on earphone. When worn, the earphone body 1 of the ear-clip earphone is partially placed in the ear cavity, and the clamping part 2 is close to the back of the ear, so that the earphone body 1 and the clamping part 2 together wrap the ear of the human body, and the ear of the human body is relatively located in the clamping space 21. The optical sensor 32 is arranged at the head end of the clamping part 2, and the window 33 is arranged at the tail end of the clamping part 2 and the window 33 is suitable for fitting the back of the ear. The optical fiber 31 connects the optical sensor 32 and the window 33 and transmits the optical signal.

[0039] Furthermore, an optical element 34 is provided at the head end of the clamping portion 2 . The optical element 34 is disposed between the optical sensor 32 and the optical fiber 31 . The optical signal generated by the optical sensor 32 is gathered into the optical fiber 31 through the optical element 34 .

[0040] In this embodiment, an optical element 34 is further provided between the optical sensor 32 and the optical fiber 31. The optical element 34 can gather the optical signal generated by the optical sensor 32 into the optical fiber 31, thereby improving the efficiency of optical signal transmission of the optical sensor 32 and improving the detection sensitivity of the optical sensor 32.

[0041] Specifically, the optical element 34 is used to gather the optical signal and make it enter the optical fiber 31. The optical element 34 includes a Fresnel lens, which is a plane lens that arranges a large number of linear lenses with triangular cross-sectional shapes in a concentric circle shape. The Fresnel lens is the same as an ordinary lens, but is thinner, which reduces the proportion of the space occupied by the optical element 34 in the clip-on earphone.

[0042] It is worth noting that the optical element 34 includes but is not limited to a Fresnel lens, and may also be other common lenses, as long as it can achieve the focusing effect of the optical signal of the optical sensor 32, it is within the protection scope of the present application.

[0043] Furthermore, the clamping portion 2 is made of soft rubber material, the clamping portion 2 is arc-shaped, and the optical fiber 31 is embedded in the middle section of the clamping portion 2 .

[0044] In this embodiment, the clamping part 2 is made of soft rubber material, and the optical fiber 31 is embedded in the middle section of the clamping part 2. The clamping part 2 serves two purposes, thereby improving the utilization rate of the internal space of the clip-on earphone.

[0045] Specifically, the clamping part 2 is made of soft rubber. When wearing, the clamping part 2 is moved to open the clamping space 21. After the earphone body 1 is placed in the ear cavity, the clamping part 2 is loosened, and the clamping part 2 is close to the back of the ear to tighten the clamping space 21, so that the clamping part 2 and the earphone body 1 wrap the ear together, making the wearing process more convenient and comfortable. When the clip-on earphone is worn on the ear of the human body, the clamping part 2 is bent and abutted against the back of the ear, and the window 33 at the end of the clamping part 2 fits the back of the ear of the human body. At this time, the optical sensor 32 can operate normally.

[0046] It is worth noting that the clamping portion 2 includes but is not limited to a soft rubber material, and can also be a hard rubber material. In this case, the clamping portion 2 can be rotatably or movably installed on the earphone body 1 to open and close the clamping space 21.

[0047] Further, refer to Figure 4 and Figure 5The earphone body 1 includes an upper cover 11 and a lower cover 12.

The first fixing portion 122 is provided with a first connecting hole 1221 at a corresponding position of the optical sensor 32, and an optical element 34 is provided in the first connecting hole 1221. The optical fiber 31 is embedded in the clamping portion 2 and the clamping portion 2 is provided with a head end portion of the optical fiber 31 that is recessed inward, so that the optical signal of the optical sensor 32 can better pass through the optical element 34 and reach the optical fiber 31.

[0049] In this embodiment, the optical sensor 32 is mounted on the circuit board assembly 4, the optical element 34 is arranged in the first connection hole 1221 of the first fixing portion 122, the optical fiber 31 is embedded in the clamping portion 2, and the positions of the optical sensor 32, the optical element 34 and the optical fiber 31 match each other, thereby improving the utilization rate of the internal stacking space of the clip-on earphone. The first fixing portion 122 is arranged at one end of the earphone body 1 away from the sound outlet portion 121 and is relatively located on the side of the earphone body 1 close to the clamping portion 2. The first fixing portion 122 is provided with a first connection hole 1221 at a corresponding position of the optical sensor 32, and the optical element 34 is arranged in the first connection hole 1221. The optical sensor 32 is arranged below the circuit board assembly 4 and is relatively located above the optical element 34. The optical fiber 31 is embedded in the clamping portion 2. The positions of the optical sensor 32, the optical element 34 and the optical fiber 31 match each other, and the optical signal generated by the optical sensor 32 is gathered into the optical fiber 31 through the optical element 34. At the same time, referring to Figure 2 The head end of the optical fiber 31 provided in the clamping portion 2 is recessed inward, so that the middle of the head end of the clamping portion 2 is recessed toward the end away from the optical sensor 32, and the light signal gathered by the optical element 34 can more easily reach the optical fiber 31, so that the light signal of the optical sensor 32 can better reach the optical fiber 31 after passing through the optical element 34, thereby improving the transmission efficiency and sensitivity of the light signal of the optical sensor 32.

[0050] It is worth noting that the circuit board assembly 4 is also provided with an antenna 41 and a microphone 42. The microphone 42 is arranged on one side of the circuit board assembly 4 close to the sound output portion 121. The circuit board assembly 4 and the upper cover 11 are also provided with a through hole 43 at the corresponding position of the microphone 42. The microphone 42 is connected to the outside world through the through hole 43. The circuit board assembly 4 is also integrated with a Bluetooth audio main control chip, a power protection chip, a crystal oscillator that provides a clock for the Bluetooth chip, an optical signal processing chip, etc.

[0051] Further, refer to Figure 6 A first bracket 22 and a second bracket 23 are provided in the sound outlet 121. The first bracket 22 is arranged at one end of the sound outlet 121 close to the upper cover 11, and the second bracket 23 is arranged at one end of the sound outlet 121 away from the upper cover 11.

In this embodiment, the circuit board assembly 4, the first bracket 22, the battery 24, the second bracket 23 and the speaker 25 are stacked, which greatly improves the utilization rate of the internal space of the sound outlet 121. It is worth noting that a charging assembly 28 and a magnet 29 are also arranged in the sound outlet 121, and the magnet 29 and the charging assembly 28 are both arranged at the bottom of the sound outlet 121. The magnet 29 is relatively located below the second bracket 23 and relatively located inside the sound outlet 121, and the charging assembly 28 is also relatively located below the second bracket 23 and relatively close to the clamping portion 2.
