[0030] As Figures 1-4 As shown in the schematic diagram of the light-emitting earphone provided by the utility model embodiment, the light-emitting earphone can be worn on the ear, and can convert the wireless audio signal from electronic devices such as mobile phones, computers and music players into sound for playing. The light-emitting earphone in the embodiment includes a first shell 10, a connecting part 20 and a second shell 30, wherein the connecting part 20 is connected between the first shell 10 and the second shell 30, and is in an arc shape suitable for the human ear; the first shell 10 is provided with a control circuit board and a sound emitting device electrically connected with the control circuit board, the second shell 30 is provided with a battery, and the control circuit board of the first shell 10 is electrically connected with the battery provided in the second shell 30 through a cable 23 passing through the connecting part 20, so as to supply power to the control circuit board by the battery in the second shell 30, and then control the sound emitting device to emit sound by the control circuit board.
[0031] In an embodiment of the utility model, the sound production device in the first shell 10 can adopt a diaphragm sound production device (i.e. a device producing sound through a diaphragm, such as a loudspeaker), and the first shell 10 has a directional sound outlet 11. Specifically, the control circuit board is provided with a wireless communication circuit (such as a Bluetooth communication circuit, a 2.4G communication circuit, etc.) and an audio codec circuit, etc., receives an audio signal from a mobile phone, a computer, a music player, etc. through the wireless communication circuit, analyzes the received audio signal through the audio codec circuit and sends it to the diaphragm sound production device to convert it into mechanical vibration of the diaphragm, thereby realizing audio playback. In addition, the control circuit board can also be integrated with a charging circuit, a microphone, etc. The first shell 10 and the second shell 30 can adopt any scheme identical to the existing earphone, which will not be described here.
[0032] In addition to the cable 23 for connecting the control circuit board and the battery, the connecting part 20 also includes an elastic rubber shell 21 and a light bar 22. The elastic rubber shell 21 is made of silicone or plastic with a certain elasticity, and has an overall arc shape that is adapted to the human ear (in a non-external force state), and can bend within a certain angle range when subjected to external force and return to its original shape when the external force is removed. Specifically, the cross section of the elastic rubber shell 21 can be oval or triangular, etc. The elastic rubber shell 21 is located between the first shell 10 and the second shell 30 (the two ends of the elastic rubber shell 21 can be connected to the first shell 10 and the second shell 30 respectively), for example, the two ends of the elastic rubber shell 21 are connected to the first shell 10 and the second shell 30 respectively. The surface of the elastic rubber shell 21 has a groove 211, and the groove 211 is arranged along the length direction of the elastic rubber shell 21. Specifically, the elastic rubber shell 21 can be made of a translucent material (i.e. a material that allows light to pass through partially), and the groove 211 can be formed together when the elastic rubber shell 21 is molded.
[0033] The light bar 22 includes a flexible circuit 221, a plurality of light emitting bodies 222, and an elastic wrapping body 223. The light emitting bodies 222 can be cold light sources such as light emitting diodes, the flexible circuit 221 is in the form of a strip, the plurality of light emitting bodies 222 are 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 respectively) and are arranged along the length direction of the flexible circuit 221, and the elastic wrapping body 223 wraps the flexible circuit 221 and the light emitting bodies 222, and the part of the elastic wrapping body 223 corresponding to the light emitting bodies 222 is transparent or translucent, i.e. the light emitted by the light emitting bodies 222 can penetrate or partially penetrate the elastic wrapping body 223, so that it can be seen from the outside. In actual application, part of the flexible circuit 221 can also be partially exposed to the elastic wrapping body 223. The width of the groove 211 and the size of the light bar 22 can be determined according to the size of the light emitting earphone, etc.
[0034] The size of the elastic wrapping body 223 of the light bar 22 (i.e. the size of the outer circumference) is adapted to the size of the groove 211 on the elastic shell 21, the light bar 22 is embedded in the groove 211, and the side of the light bar 22 facing the light emitter 222 is exposed from the opening of the groove 211 (i.e. the opening of the groove 211 is not closed, and the light bar 22 can be seen through the opening of the groove 211). Correspondingly, the control circuit board in the first shell 10 has a light emitting driving circuit (for example, 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 emitters 222 can emit light under the control of the light emitting driving circuit, and at least part of the light emitted by the light emitters 222 can pass through the elastic wrapping body 223 and the opening of the groove 211 and be visible to the outside. The light emitting driving circuit can be specifically used by the conventional technology in the art, and will not be described here.
[0035] The above-mentioned light-emitting earphone expands the light-emitting area of the earphone by setting the groove 211 on the elastic shell 21 and embedding the flexible circuit 221 and the light emitter 222 wrapped by the elastic wrapping body 223 into the groove 211, relative to the prior art of setting a single light-emitting point on the first shell 10 or the second shell 30. For example, the light-emitting area can be expanded to the entire connecting part 20. The above-mentioned light bar 22 can be produced in advance, so that when the light-emitting earphone is assembled, the light bar 22 only needs to be inserted into the groove 211 on the surface of the elastic shell 21 prepared in advance, which greatly facilitates the assembly of the light-emitting earphone. Relative to the way of setting the light bar 22 or the light emitter 222 inside the elastic shell 21, the above-mentioned structure can simplify the assembly of the light-emitting earphone and reduce the production cost of the light-emitting earphone.
[0036] Moreover, since the elastic wrapping body 223 wraps the light emitter 222 and the flexible circuit 221 together, the strength of the light bar 22 is greatly increased, and the subsequent assembly process will not cause the flexible circuit 221 to break or the light emitter 222 to fall off (including falling off or disconnection of electrical connection) from the flexible circuit 221, thereby improving the yield.
[0037] In actual application, the battery can also be placed in the first shell 10, i.e. the light-emitting earphone no longer has the second shell 30, the connecting part 20 is connected to the first shell 10, and the wearing of the light-emitting earphone is realized through the connecting part 20 (for example Figure 6 , Figure 7 In the embodiment of the application, the light-emitting earphone is directly hung on the external auditory meatus through the connecting part 20). Correspondingly, the connecting part 20 also does not need to be provided with a cable for connecting the battery.
[0038] In an embodiment of the present application, the flexible circuit 221 comprises a flexible substrate and a printed circuit disposed on the flexible substrate, and the plurality of light emitting bodies 222 are fixed on the flexible substrate and electrically connected to the printed circuit. The flexible substrate can be electrically connected to the control circuit board in the first housing 10 through a cable or a terminal (e.g. electrically connected to the light emitting driving circuit on the control circuit board), so that the control circuit board can control the light emitting of the light emitting bodies 222. In addition, the flexible substrate can further have a reflective layer, so as to increase the light output. Meanwhile, in order to reduce the cost, the part of the elastic wrapping 223 on the side opposite to the light emitting bodies 222 can be made of a non-transparent material. Of course, in actual application, the flexible circuit 221 can also be made of a connecting wire, but the strength is relatively low.
[0039] In order to make the light emitting of the light bar 22 more easily seen by the outside, in an embodiment of the present application, the size of the groove 211 in the length direction of the elastic rubber shell 21 exceeds half of the length of the elastic rubber shell 21, for example, extends more than half of the length of the elastic rubber shell 21 from the first housing 10 to the second housing 30, and correspondingly, the size of the light bar 22 in the length direction of the connecting part 20 also exceeds half of the length of the connecting part 20.
[0040] In particular, in order to maximize the light emitting size, the groove 211 on the elastic rubber shell 21 extends from the first housing 10 to the second housing 30, and the size of the light bar 22 in the first direction is greater than or equal to the size of the groove 211 in the first direction, and the first direction is the length direction of the elastic rubber shell 21. That is, the light bar 22 extends from the first housing 10 to the second housing 30 along the length direction of the connecting part 20.
[0041] In order to stably fix the light bar 22 in the groove 211, in an embodiment of the present application, the elastic wrapping 223 can be made of an elastic material (e.g. silica gel), and the outer diameter of the elastic wrapping 223 is the same at different positions in the length direction of the light bar 22, and the light bar 22 is tightly fitted with the groove wall of the groove 211 through the elastic wrapping 223, so that the light bar 22 cannot rotate after being embedded in the groove 211, and the light emitting bodies 222 always face the opening of the groove 211.
[0042] Specifically, the width of the opening of the groove 211 on the elastic shell 21 can be made smaller than the maximum width of the interior of the groove 211, for example, the cross section of the groove 211 is in the shape of C or dovetail, correspondingly, the maximum dimension of the light bar 22 in the second direction is smaller than the dimension of the opening of the groove 211 in the second direction, the second direction is the width direction of the opening of the groove 211. In this way, when the light bar 22 is embedded into the groove 211, an external force needs to be applied so that the light bar 22 is deformed under pressure and passes through the opening of the groove 211 and is embedded into the groove 211. Through this structure, the light bar 22 can be directly fixed in the groove 211 by the elastic wrapping body 223 itself without the need of glue or buckle structures, further saving the assembly process and cost.
[0043] In addition, in order to further improve the bonding strength of the light bar 22 and the elastic shell 21, an adhesive layer can be added between the bottom wall of the groove 211 and the outer side wall of the elastic wrapping body 223 of the light bar 22, and the elastic shell 21 and the light bar 22 are adhered together through the adhesive layer. At this time, the Young's modulus of the elastic wrapping body 223 needs to be smaller than the Young's modulus of the elastic shell 21, so as to avoid the influence of the light bar 22 on the deformation of the elastic shell 21.
[0044] In order to improve the clamping force of the connecting part 20 when worn, in an embodiment of the present application, the connecting part 20 can further include an elastic metal wire 24 arranged along the length direction of the elastic shell 21, and the elastic metal wire 24 can be injection molded together with the cable 23 in the elastic shell 21. Of course, in actual application, the elastic metal wire 24 and the cable 23 can also be inserted into the elastic shell 21 after the elastic shell 21 is formed (a through hole is formed in the elastic shell 21 in advance). In actual application, the connecting part 20 can also not be provided with the elastic metal wire 24, and the elastic force of the elastic shell 21 itself is used to form the clamping force on the earphone worn.
[0045] In an embodiment of the present application, the above-mentioned light-emitting earphone can be a clip-on earphone, that is, the connecting part 20 is in the shape of a circular arc, the first shell 10 is inserted into the concha cavity in the wearing state, the connecting part 20 is wrapped around the front side of the auricle to the rear side of the auricle in the wearing state, and the second shell 30 is located at the rear side of the auricle in the wearing state.
[0046] Moreover, when the light-emitting earphone is worn on the ear, the opening of the groove 211 faces away from the auricle (as shown in Figure 1 That is, the side of the connecting part 20 of the light-emitting earphone facing away from the face of the human body emits light, so that the light-emitting area can be more clearly observed from the outside.
[0047] Or, as shown in Figure 5As shown, when the light-emitting earphone is worn on the ear, the opening of the recess 211 faces the auricle and the elastic rubber shell 21 is made of translucent material (so that the cable 23 and the elastic wire 24 in the elastic rubber shell 21 are not visible, avoiding the appearance being messy), that is, the light bar 22 emits light towards the human body and is observed by being irradiated to the human skin, improving the integrity of the light emission, that is, the light-emitting body 222 on the light bar 22 is not observed as a dot.
[0048] In an embodiment of the present application, as shown in Figure 6 , Figure 7 The light-emitting earphone can also be a hanging ear type earphone, and correspondingly, the connecting part 20 is in the shape of a hook adapted to the shape of the root of the auricle, the first shell 10 is located at the front side of the auricle in the wearing state, the connecting part 20 is wound from the front side of the auricle to the back side of the auricle through the top end of the auricle in the wearing state, and the second shell 30 is located at the back side of the auricle in the wearing state.
[0049] Correspondingly, when the light-emitting earphone is worn on the ear, the opening of the recess 211 can face away from the auricle (as shown in Figure 7 ), face the auricle (as shown in Figure 6 ), or face the face of the human body. That is, the opening of the recess 211 faces upward, downward or inward of the connecting part, and in this way, the light emission can also be clearly observed from the outside.
[0050] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
