[0033] Such as Figures 1 - 3As shown in the figure, it is a schematic diagram of the in-ear light-emitting earphone provided by an embodiment of the present utility model. This in-ear light-emitting earphone can be worn on the ear and convert the wireless audio signal from electronic devices such as mobile phones, computers, and music players into sound for playback. The in-ear light-emitting earphone in this embodiment includes a sound-generating part 10, a connecting part 20, and a battery part 30. Among them, the connecting part 20 is connected between the sound-generating part and the battery part and is in an arc shape adapted to the human ear; a control circuit board is provided in the sound-generating part 10, a battery is provided in the battery part 30, and the control circuit board of the sound-generating part 10 is electrically connected to the battery provided in the battery part 30 through a cable 23 passing through the connecting part 20, so that the battery in the battery part 30 supplies power to the control circuit board. Moreover, this in-ear light-emitting earphone is worn on the outer ear of the human body through the connecting part 20.

[0034] The above-mentioned sound-generating part 10 further includes a main housing and a diaphragm sound-generating device (i.e., a device that generates sound through a diaphragm, such as a speaker), and the main housing has a directional sound outlet hole 111. The above-mentioned diaphragm sound-generating device and the control circuit board are respectively arranged in the main housing, and the diaphragm sound-generating device is electrically connected to the control circuit board. The control circuit board has a wireless communication circuit (such as a Bluetooth communication circuit, a 2.4G communication circuit, etc.) and an audio codec circuit, etc., and receives an audio signal from electronic devices such as mobile phones, computers, and music players through the wireless communication circuit, and then analyzes the received audio signal through the audio codec circuit and sends it to the diaphragm sound-generating device to be converted into mechanical vibration of the diaphragm, thereby realizing audio playback. In addition, a charging interface, a charging circuit, a microphone, etc. can also be integrated on the above-mentioned control circuit board. Specifically, the sound-generating part 10 and the battery part 30 can adopt any scheme the same as that of the existing in-ear earphone, and will not be elaborated here.

[0035] In addition to the cable 23 for connecting the control circuit board and the battery, the above-mentioned connecting part 20 further includes an elastic sleeve 21 and a light bar 22. Among them, the elastic sleeve 21 is made of silica gel or a plastic with a certain elasticity, etc., and it can bend within a certain angle range when subjected to an external force (in a state without external force, it is in an arc shape adapted to the human ear). The elastic sleeve 21 is located between the sound-generating part 10 and the battery part 30 (the two ends of the elastic sleeve 21 can be respectively connected to the sound-generating part 10 and the battery part 30), and the elastic sleeve 21 includes a first tube hole 213, and the first tube hole 213 is arranged along the axial direction of the elastic sleeve 21 (that is, the first tube hole 213 is arranged along the length direction of the elastic sleeve 21), and a light-transmitting part is arranged axially on the tube wall of the first tube hole 213, that is, the light-transmitting part is in a strip shape and is arranged along the length direction of the elastic sleeve 21. Specifically, the above-mentioned light-transmitting part can be formed by making the corresponding part of the tube wall of the first tube hole 213 adopt a transparent material or a translucent material, or by making the thickness of this part of the tube wall relatively small.

[0036] The light bar 22 includes a flexible circuit 221, a plurality of light-emitting bodies 222, and a wrapping body 223. Among them, the light-emitting bodies 222 can adopt cold light sources such as light-emitting diodes. The flexible circuit 221 is strip-shaped. The plurality of light-emitting bodies 222 are respectively arranged on the same surface of the flexible circuit 221 (the plurality of light-emitting bodies 222 are electrically connected to the flexible circuit 221), and the plurality of light-emitting bodies 222 are arranged along the length direction of the flexible circuit 221. The wrapping body 223 wraps the flexible circuit 221 and the light-emitting bodies 222, and the part of the wrapping body 223 corresponding to the light-emitting bodies 222 is transparent or semi-transparent. In practical applications, a part of the flexible circuit 221 can also be partially exposed from the wrapping body 223.

[0037] The light bar 22 is inserted into the first tube hole 213 of the elastic sleeve 21 in such a way that the light-emitting bodies 222 face the light-transmitting part. The control circuit board in the sound-generating part 10 has a light-emitting driving circuit (such as an LED driving circuit), and the flexible circuit 221 is electrically connected to the light-emitting driving circuit on the control circuit board, so that the plurality of light-emitting bodies 222 can emit light under the control of the light-emitting driving circuit. The light-emitting driving circuit can specifically adopt the conventional techniques in the field and will not be elaborated here.

[0038] For the above in-ear light-emitting earphone, the flexible circuit 22 integrated with the light-emitting bodies 222 is wrapped by the wrapping body 223 to form the light bar 22 (the light bar 22 can be pre-produced), and then the light bar 22 is inserted into the elastic sleeve in the connecting part. A light-transmitting part is arranged on the tube wall of the elastic sleeve 21. Compared with the existing single-point light emission in the sound-generating part 10 or the battery part 30, the light-emitting area of the in-ear earphone is expanded. For example, the light-emitting area can be expanded to the entire connecting part 20. And because the wrapping body 223 wraps the light-emitting bodies 222 and the flexible circuit 22 together, the strength of the light bar 22 is greatly increased, which is convenient for threading operation and will not cause the flexible circuit 221 to break or the light-emitting bodies 222 to fall off from the flexible circuit 221 (including dropping or disconnection of the electrical connection) during the threading process, improving the yield rate.

[0039] In practical applications, the battery can also be placed in the main housing of the sound-generating part 10, that is, the in-ear light-emitting earphone no longer has a battery part 30. The connecting part 20 is connected to the sound-generating part 10, and the in-ear light-emitting earphone is worn through the connecting part 20. Correspondingly, there is no need to set a cable for connecting the battery in the connecting part 20 either.

[0040] In an embodiment of the present invention, the above light bar 22 can also be integrally injection-molded with the elastic sleeve 21 in such a way that the light-emitting bodies 222 face the light-transmitting part.

[0041] In order to make the light-emitting area easier to be clearly observed from the outside, in an embodiment of the present invention, the size of the light-transmitting portion of the elastic sleeve 21 in the length direction of the connecting portion 20 exceeds half of the length of the connecting portion 20, and the light-transmitting portion is located on the side of the elastic sleeve 21 facing away from the directional sound outlet hole 111, that is, when the earphone is worn on the ear, the light-transmitting portion is located on the side facing away from the human face, so that the outside can more clearly observe the light-emitting area. In practical applications, the light-transmitting portion can also be located on the outer edge of the arc of the elastic sleeve 21, for example Figure 1 the upper edge of the connecting portion 20 in [description of the reference]. That is, when the earphone is worn on the ear, the light-transmitting portion is exposed at the part in contact with the human body and can also be clearly observed from the outside. In addition, the light-transmitting portion can also be located on the same side as the directional sound outlet hole 111 of the earphone with opposite-ear light emission, that is, when the earphone is worn on the ear, the light-transmitting portion is located on the side facing the human face and can be seen by irradiating the human skin, improving the integrity of its light emission, that is, the light-emitting bodies 222 on the light bar 22 will not be observed in a point-like manner.

[0042] In an embodiment of the present invention, the elastic sleeve 21 is composed of a first tube wall 211 and a second tube wall 212 arranged axially respectively, and the first tube hole 213 is surrounded by the first tube wall 211 and the second tube wall 212. For example, the cross-sections of the first tube wall 211 and the second tube wall 212 are both semi-circular rings. The light-transmitting property of the first tube wall 211 is greater than that of the second tube wall 212, and the light-transmitting portion is composed of the first tube wall 211, that is, the elastic sleeve 21 is integrally injection-molded by the first tube wall 211 and the second tube wall 212, and the light-transmitting portion axially penetrates the entire elastic sleeve 21, maximizing the light-emitting area.

[0043] In specific implementation, according to the material of the elastic sleeve 21, the thickness of the first tube wall 211 can be made to reach the degree that can transmit light, so as to achieve the light transmission of the first tube wall 211 and the non-light transmission (or relatively poor light-transmitting performance) of the second tube wall 212; alternatively, different materials can also be used to form the first tube wall 211 and the second tube wall 212. For example, an opaque pigment is incorporated into the material forming the second tube wall 212, so that the first tube wall 211 transmits light and the second tube wall 212 does not transmit light. By providing the second tube wall with non-light transmission or relatively poor light-transmitting performance on the elastic sleeve 21, it is convenient to hide the contour of the cable 23 or the light bar 21 inside the elastic tube sleeve 21 and avoid a messy appearance. Of course, in practical applications, the elastic sleeve 21 can also be made of a material with uniform light-transmitting performance, that is, the entire elastic sleeve 21 constitutes the light-transmitting portion.

[0044] In order to stably fix the light bar 22 in the first pipe hole 213, in an embodiment of the present invention, the wrapping body 223 is made of an elastic material (such as silica gel, etc.), and the light bar 22 is tightly fitted with the pipe wall of the first pipe hole 213 through the wrapping body 223, that is, an external force needs to be applied when the light bar 22 is inserted into the first pipe hole 213, so that the light bar 22 will not rotate after being inserted into the first pipe hole 213, and the light-emitting body 222 always faces the light-transmitting part of the elastic sleeve 21.

[0045] Moreover, in order to facilitate the insertion of the light bar 22 into the first pipe hole 213, the outer diameters of the wrapping body 223 are the same at different positions in the length direction, that is, the part of the light bar 22 in the first pipe hole 213 has a uniform thickness.

[0046] In an embodiment of the present invention, the flexible circuit 221 includes a flexible substrate and a printed circuit provided on the flexible substrate. A plurality of light-emitting bodies 222 are fixed on the flexible substrate and are respectively electrically connected to the printed circuit. The flexible substrate can be electrically connected to the control circuit board in the sound-generating part 10 through a cable or a terminal (for example, electrically connected to the light-emitting driving circuit on the control circuit board), so as to realize the light-emitting control of the control circuit board over the light-emitting body 222. The part of the wrapping body 223 on the side of the light-emitting body 222 is made of a transparent or semi-transparent material. Moreover, a reflective layer can also be provided on the flexible substrate to increase the light output. At the same time, in order to reduce costs, the part of the wrapping body 223 on the side facing away from the light-emitting body 222 is made of an opaque material.

[0047] Of course, in practical applications, the flexible circuit 221 can also be composed of connecting wires, etc., but its strength is relatively low, and during the process of inserting the light bar 22 into the first pipe hole 213, the light-emitting body 222 is extremely easy to fall off or break the wire.

[0048] In an embodiment of the present invention, the cable 23 for connecting the control circuit board and the battery is inserted into the first pipe hole 213 together with the light bar 22, and the cable 23 is located on the side of the first pipe hole 213 facing away from the light-transmitting part, so as not to affect the light output of the light bar 22. In this way, the light bar 22 and the cable 23 can be inserted into the first pipe hole 213 together, improving the processing efficiency.

[0049] To increase the clamping force of the connecting portion 20 during wearing, in an embodiment of the present utility model, the connecting portion 20 includes an elastic metal wire 24. The elastic metal wire 24 and the light bar 22 are both passed through the first tube hole 213, and the elastic metal wire 24 is located on the side of the first tube hole 213 facing away from the light-transmitting portion, so as not to affect the light emission of the light bar 22. In this way, the light bar 22 and the elastic metal wire 24 can be inserted into the first tube hole 213 together, improving the processing efficiency. Of course, the light bar 22, the cable 23, and the elastic metal wire 24 can be passed through the first tube hole 213 together. In practical applications, the connecting portion 20 may not be provided with the elastic metal wire 24, and the elastic force of the elastic sleeve 21 itself can be used to provide the clamping force for wearing the earphone.

[0050] As Figure 4 shown, in an embodiment of the present utility model, the elastic sleeve 21 may further include a second tube hole and a third tube hole in the axial direction (i.e., the length direction), and both the second tube hole and the third tube hole are far from the light-transmitting portion; the above-mentioned cable 23 is passed through the second tube hole, and the elastic metal wire 24 is passed through the third tube hole. In this structure, since the light bar 22, the cable 23, and the elastic metal wire 24 are respectively passed through three tube holes, their radial positions will not move relatively, thus avoiding the cable 23 and the elastic metal wire from blocking the light emission of the light bar 22. Of course, since the light bar 22, the cable 23, and the elastic metal wire 24 need to be respectively passed through three tube holes, the process is relatively complex.

[0051] Specifically, as Figure 5 shown, the elastic sleeve 21 includes a first portion 215 and a second portion 216 arranged along the length direction, and the light-transmitting property of the first portion 215 is greater than that of the second portion 216. The first tube hole 213 is located in the first portion, and the second tube hole 217 and the third tube hole 218 are both located in the second portion 216. By the above method, the positions of the light bar 22, the cable 23, and the elastic metal wire 24 in the elastic sleeve 21 can be relatively fixed, avoiding relative movement during use. The cross-sections of the above-mentioned first portion 215 and second portion 216 can be semi-circular respectively. In practical applications, the radial dimensions of the first portion 215 and the second portion 216 can also be adjusted according to the radial dimensions of the light bar 22, the cable 23, and the elastic metal wire 24. For example, the radial dimension of the first portion 215 can be made larger than the radial dimension of the second portion 216.

[0052] In addition, two tube holes may be provided only in the elastic sleeve 21, and the light strip 22 and the cable 23 may be passed through one of the tube holes, and the elastic wire 24 may be passed through the other tube hole (or the elastic wire 24 is integrally injection-molded with the elastic sleeve 21); or the light strip 22 and the elastic wire 24 may be passed through one of the tube holes, and the cable 23 may be passed through the other tube hole; or the elastic wire 24 and the cable 23 may be passed through one of the tube holes, and the light strip 22 is separately passed through the other tube hole. For the embodiment without the battery part 30, the light strip 22 and the elastic wire 24 may be separately passed through the two tube holes. For the embodiment without the elastic wire 24, the light strip 22 and the cable 23 may be separately passed through the two tube holes.

[0053] The above in-ear light-emitting earphone may be, for example, Figure 1 the ear-hook type earphone shown in the figure. The connecting part 20 of the earphone is in a hook shape adapted to the shape of the root of the auricle. The sound generating part 10 and the battery part 30 may adopt the conventional structures of existing ear-hook type earphones. And the sound generating part 10 is located on the front side of the auricle in the wearing state, the connecting part 20 goes around from the front side of the auricle to the rear side of the auricle through the top of the auricle in the wearing state, and the battery part 30 is located on the rear side of the auricle in the wearing state.

[0054] The above in-ear light-emitting earphone may be, for example, Figure 6 the clip-on earphone shown in the figure. Correspondingly, the connecting part 20 of the earphone is in an arc shape. The sound generating part 10 and the battery part 30 may adopt the conventional structures of existing clip-on earphones. And the sound generating part 10 is inserted into the concha in the wearing state, the connecting part 20 goes around from the front side of the auricle to the rear side of the auricle through the side of the auricle in the wearing state, and the battery part 30 is located on the rear side of the auricle in the wearing state.

[0055] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
