Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] This utility model embodiment provides an earphone 1000, such as Figures 1-4 As shown, the earphone 1000 includes a first housing 110 and a battery 120, a first flexible pad 130, and a heart rate monitoring module 140 disposed inside the first housing 110. The heart rate monitoring module 140 is electrically connected to the battery 120 to obtain power. The first flexible pad 130 is disposed between the battery 120 and the heart rate monitoring module 140 and is used to press the battery 120 and the heart rate monitoring module 140 against the first housing 110 through deformation.

[0020] Therefore, compared with the prior art of using screws and internally threaded posts to install the heart rate monitoring module 140, the present invention does not require the internally threaded posts to be set in the first housing 110, so the structure of the first housing 110 is simpler, the production difficulty of the first housing 110 is lower, and the production cost is lower.

[0021] In addition, when the earphone 1000 is dropped or encounters other situations that cause the first housing 110 to be impacted by external force, the first flexible pad 130 can play a buffering role by deformation, providing protection for the battery 120 and the heart rate monitoring module 140 to a certain extent.

[0022] The first flexible pad 130 can be an EVA cotton pad, a silicone pad, or a rubber pad. This embodiment does not limit it, as long as it can hold the battery 120 and the heart rate monitoring module 140 tightly against the first outer shell 110 through deformation.

[0023] In some embodiments, a glue layer (not shown in the figure) is provided inside the first housing 110. The glue layer is in contact with the first housing 110 and the heart rate monitoring module 140, thereby fixing the heart rate monitoring module 140 to the first housing 110.

[0024] It should be noted that the glue-injection layer is formed by the curing of glue after it has been injected, hence the name glue-injection layer.

[0025] Implementing this embodiment effectively increases the connection stability of the heart rate monitoring module 140. It is worth noting that while a single adhesive layer can be used to install the heart rate monitoring module 140 onto the first housing 110 without the first flexible pad 130 being used to press it against the module, the adhesive layer is prone to aging and detachment after a period of use, causing the heart rate monitoring module 140 to become disconnected from the first housing 110. Therefore, this embodiment provides both the first flexible pad 130 to press the heart rate monitoring module 140 against the module and an adhesive layer to connect the heart rate monitoring module 140 and the first housing 110.

[0026] refer to Figures 1-4 In some embodiments, the first housing 110 is provided with a light-transmitting opening 111 connecting its inner and outer sides, and a lens 150 is installed at the light-transmitting opening 111. The first housing 110 is also provided with a second flexible pad 160, which abuts against the side of the lens 150 away from the second housing 170. The heart rate monitoring module 140 abuts against the side of the second flexible pad 160 away from the lens 150.

[0027] Specifically, the lens 150 can prevent external dust and contaminants from entering the first housing 110 through the light-transmitting port 111 and contaminating the heart rate monitoring module 140. Therefore, the lens 150 can provide a certain degree of protection for the heart rate monitoring module 140. The second flexible pad 160 can provide cushioning to prevent the heart rate monitoring module 140 from making hard contact with the lens 150.

[0028] refer to Figures 3-5 In a specific embodiment, the second flexible pad 160 is made of a light-shielding material, and two spaced-apart through holes 161 are formed on the second flexible pad 160. The heart rate monitoring module 140 includes a circuit board 141, a light-emitting element 142, and a photosensitive element 143. The circuit board 141 is electrically connected to the battery 120 and abuts against the side of the second flexible pad 160 away from the lens 150. The light-emitting element 142 and the photosensitive element 143 are both mounted on the circuit board 141, with the light-emitting element 142 housed in one of the through holes 161 and the photosensitive element 143 housed in the other through hole 161. The light-emitting element 142 is used to emit light toward the user's skin, and the photosensitive element 143 is used to receive light reflected back from the user's skin.

[0029] The light-blocking material can be opaque EVA cotton, black silicone, or other opaque silicone of other colors. This embodiment does not limit the material, as long as it is flexible and opaque.

[0030] By implementing this embodiment, the light emitted by the light-emitting element 142 can be effectively prevented from directly escaping to the photosensitive element 143, thereby improving the monitoring accuracy of the heart rate monitoring module 140.

[0031] Specifically, the light-emitting element 142 can emit light. When the light penetrates the skin, part of it is absorbed by the skin and the other part is reflected. The photosensitive element 143 can receive the reflected light. Since the heartbeat causes changes in the blood volume in the skin, the increase in blood volume will increase the amount of light absorption and decrease the amount of light reflection. Therefore, the heart rate can be determined based on the light received by the photosensitive element 143.

[0032] More specifically, the light-emitting element 142 can be a light-emitting diode that can emit green or red light, and the photosensitive element 143 can be a photodiode or a photoresistor; this embodiment is not limited to these.

[0033] refer to Figure 5 In a specific embodiment, the lens 150 is provided with a first mounting groove 151 on the side facing the battery 120, and a second mounting groove 152 is provided at the bottom of the first mounting groove 151. The circuit board 141 is limited and mounted in the first mounting groove 151, and the second flexible pad 160 is limited and mounted in the second mounting groove 152.

[0034] By implementing this embodiment, a first mounting groove 151 for mounting the circuit board 141 and a second mounting groove 152 for mounting the second flexible pad 160 are provided on the lens 150, so that the second flexible pad and the circuit board 141 have a clear assembly position, reducing the occurrence of the second flexible pad 160 and the circuit board 141 being misaligned, which would lead to a decrease in the detection accuracy of the heart rate monitoring module 140, increasing the product yield and ensuring high consistency of the manufactured products.

[0035] refer to Figure 1 In a specific embodiment, the first outer shell 110 includes a first shell 112 and a second shell 113 that are interlocked. A light-transmitting opening 111 is disposed on the first shell 112, and an adhesive layer (not shown in the figure) is also disposed on the first shell 112. The adhesive layer contacts the lens 150, the circuit board 141, and the first shell 112 to fix the lens 150, the circuit board 141, and the first shell 112 in place. During assembly, the lens 150 and the circuit board 141 are first fixed to the first shell 112, and then the first shell 112 is interlocked with the second shell 113.

[0036] It should be noted that the glue-injection layer is formed by the curing of glue after it has been injected, hence the name glue-injection layer.

[0037] By implementing this embodiment, the connection stability between the heart rate monitoring module 140, the lens 150, and the first housing 112 can be effectively increased. It is worth mentioning that if only an adhesive layer is provided, without using the first flexible pad 130 to press against the heart rate monitoring module 140, the lens 150, and the first housing 110, a fixed connection can be achieved for a certain period. However, after a period of use, the adhesive layer is prone to aging and delamination, causing the heart rate monitoring module 140, the lens 150, and the first housing 110 to detach. Therefore, this embodiment provides both the first flexible pad 130 to press against the heart rate monitoring module 140 and an adhesive layer to connect the heart rate monitoring module 140, the lens 150, and the first housing 110.

[0038] refer to Figure 1 and Figure 6 In some embodiments, the earphone 1000 further includes a second housing 170 and a spring arm 180. The second housing 170 is disposed on one side of the first housing 110, and a sound-generating unit 220 is disposed within the second housing 170. The spring arm 180 is bent, with one end connected to the first housing 110 and the other end connected to the second housing 170, so as to deform and store energy when the first housing 110 and the second housing 170 are far apart.

[0039] This embodiment demonstrates an earphone 1000 that can be clipped onto the ear. When in use, the first outer shell 110 is clipped to the outside of the ear and the second outer shell 170 is clipped to the inside of the ear. The elastic force provided by the elastic arm 180 causes the first outer shell 110 and the second outer shell 170 to cooperate in clamping the user's ear.

[0040] refer to Figure 1 In a specific embodiment, the lens 150 is disposed at the center of the first housing 110 facing the second housing 170, and the lens 150 protrudes from the first housing 110.

[0041] Specifically, since the lens 150 is located at the center of the first housing 110 facing the second housing 170, and the lens 150 protrudes from the first housing 110, it can be ensured that the lens 150 can contact the user's skin when the earphone 1000 is worn. This ensures that the lens 150 and the heart rate monitoring module 140 inside the lens 150 will not move relative to the user's skin during use, which is beneficial to ensuring the detection accuracy of the heart rate monitoring module 140.

[0042] refer to Figure 2In some embodiments, the first housing 110 further includes a motherboard 190 and a battery mounting block 210. The motherboard 190 is electrically connected to the battery 120 and the heart rate monitoring module 140, with one side of the motherboard 190 abutting against the inner wall of the first housing 110. The heart rate monitoring module 140 is electrically connected to the motherboard 190. The battery mounting block 210 is mounted on the other side of the motherboard 190, the battery 120 is mounted on the side of the battery mounting block 210 away from the motherboard 190, and the first flexible pad 130 is disposed on the side of the battery 120 away from the motherboard 190.

[0043] By implementing this embodiment, the first flexible pad 130 can apply a force to the heart rate monitoring module 140 on one side and a force to the battery 120 on the other side. The force is transmitted to the motherboard 190 through the battery mounting block 210. Since the motherboard 190 abuts against the inner wall of the first housing 110, the first housing 110 will provide a reverse force, so that the battery 120 and the heart rate monitoring module 140 can be pressed tightly against the first housing 110 by the first flexible pad 130.

[0044] It is worth mentioning that, in embodiments where the sound-generating unit 220 and the main board 190 are housed in the same housing, a wire (not shown in the figure) can be installed inside the housing. One end of the wire is soldered to the sound-generating unit 220, and the other end is soldered to the main board 190, thereby achieving an electrical connection between the sound-generating unit 220 and the main board 190. For the earphone 1000 described above, which has a second housing 170, with the sound-generating unit 220 mounted in the second housing 170 but the main board 190 mounted in the first housing 110, a wire 230 can be used to pass through the elastic arm 180. One end of the wire 230 is inserted into the first housing 110 and soldered to the main board 190, and the other end is inserted into the second housing 170 and soldered to the sound-generating unit 220, thereby achieving an electrical connection between the sound-generating unit 220 and the main board 190.

[0045] refer to Figure 7 and Figure 8 In a specific embodiment, a support block 114 is provided inside the first outer shell 110. The support block 114 is located on the side of the first outer shell 110 away from the light-transmitting opening 111. A first pin 1141 is provided on the support block 114. One side of the main board 190 abuts against the support block 114, and a first socket 191 is provided on the main board 190. The first pin 1141 is inserted into the first socket 191.

[0046] This embodiment illustrates a specific implementation of a limiting installation of the motherboard 190. Specifically, when the motherboard 190 abuts against the support block 114, the first pin 1141 on the support block 114 will be inserted into the first socket 191 of the motherboard 190, thereby constraining the position of the motherboard 190.

[0047] Alternatively, in another embodiment, the motherboard 190 can be glued to the inner wall of the first housing 110, which can also achieve the limiting installation of the motherboard 190.

[0048] Of course, it is understandable that in the embodiment where the motherboard 190 is installed by using the first pin 1141 in conjunction with the first socket 191, some glue can also be applied to the support block 114 to increase the connection stability of the motherboard 190.

[0049] refer to Figure 7 and Figure 8 In some embodiments, the battery mounting block 210 has a second pin 211 on the side facing away from the battery 120, and the main board 190 has a second socket 192, with the second pin 211 inserted into the second socket 192.

[0050] This embodiment illustrates a specific implementation of a battery mounting block 210 with a limiting installation. Specifically, the second pin 211 on the battery mounting block 210 is inserted into the second socket 192 of the motherboard 190, thereby constraining the position of the battery mounting block 210.

[0051] Alternatively, in another embodiment, the battery mounting block 210 can be glued to the motherboard 190, which can also achieve the limited installation of the battery mounting block 210.

[0052] Of course, it is understandable that in the embodiment where the battery mounting block 210 is installed by using the second pin 211 in conjunction with the second socket 192, some glue can be applied to the contact position between the battery mounting block 210 and the motherboard 190 to increase the connection stability of the battery mounting block 210.

[0053] refer to Figure 8 In some embodiments, the battery mounting block 210 has a third mounting groove 212 on the side away from the motherboard 190, and the battery 120 is limited to be installed in the third mounting groove 212.

[0054] The third mounting slot 212 can provide a clear mounting position for the battery 120, which can effectively prevent the battery 120 from being installed off-center, resulting in high product consistency.

[0055] refer to Figure 2 and Figure 3 In some embodiments, the circuit board 141 is a flexible circuit board. The circuit board 141 includes a mounting portion 1411 for mounting the light-emitting element 142 and the photosensitive element 143, and a connecting portion 1412 electrically connected to the motherboard 190. In this way, although the light-emitting element 142 and the photosensitive element 143 are spaced apart from the motherboard 190, the heart rate monitoring module 140 can still be directly connected to the motherboard 190.

[0056] Alternatively, the circuit board 141 can also be a rigid circuit board. In this case, the circuit board 141 needs to be connected to the motherboard 190 via wires (not shown in the figure) to achieve an electrical connection between the heart rate monitoring module 140 and the motherboard 190.

[0057] In some embodiments, the transmittance of the lens 150 is greater than 90%, which can avoid significant loss of light signals when they enter and exit the lens 150, and provide a high-quality data foundation for the heart rate monitoring module 140.

[0058] In some embodiments, lens 150 is a Fresnel lens. Fresnel lenses have excellent light-gathering capabilities and are thinner and lighter than traditional convex lenses. Therefore, Fresnel lenses are selected for lens 150 in this embodiment.

[0059] In a specific embodiment, lens 150 is made of acrylic, a low-cost and easily processed plastic that is ideal for manufacturing Fresnel lenses.

[0060] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
