[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 ear clip-on earphone 1000, such as Figure 1-5 As shown, the clip-on earphone 1000 includes a battery housing 110, a speaker housing 120, a spring arm 130, a sound-generating unit 140, and a heart rate monitoring module 150. The speaker housing 120 is disposed on one side of the battery housing 110 and includes a first housing 121 and a second housing 122 that interlock with each other. The first housing 121 has a monitoring port 1211 on the side facing the battery housing 110. One end of the spring arm 130 is connected to the battery housing 110, and the other end is connected to the first housing 121, so as to deform and store energy when the speaker housing 120 and the battery housing 110 are separated. The sound-generating unit 140 is installed inside the second housing 122. The heart rate monitoring module 150 is installed inside the first housing 121 and faces the monitoring port 1211, so that the heart rate monitoring module 150 can monitor the user's heart rate through the monitoring port 1211.

[0020] Specifically, since the heart rate monitoring module 150 of the ear clip-on earphone 1000 provided in this embodiment is installed in the first housing 121 of the speaker housing 120, and the sound-emitting unit 140 is installed in the second housing 122 of the speaker housing 120, compared with the prior art where both the sound-emitting unit 140 and the heart rate monitoring module 150 are installed on the second housing 122 of the speaker housing 120, the operator does not need to complete the installation of the heart rate monitoring module 150 and the sound-emitting unit 140 in a small assembly space. Therefore, by implementing this embodiment, after the heart rate monitoring module 150 and the sound-emitting unit 140 are installed separately, the installation operation is less difficult, and the assembly efficiency is higher.

[0021] refer to Figure 3 and Figure 5 In a specific embodiment, the first housing 121 has a slot 1212 on the side facing the second housing 122. The slot 1212 is located on the side of the first housing 121 near the battery housing 110. The monitoring port 1211 is connected to the wall of the slot 1212. The heart rate monitoring module 150 is inserted into the slot 1212.

[0022] This embodiment illustrates a specific implementation of installing the heart rate monitoring module 150 inside the first housing 121. Specifically, a slot 1212 is provided on the side of the first housing 121 facing the second housing 122, so that the heart rate monitoring module 150 can be inserted into the first housing 121.

[0023] Specifically, in order to bring the heart rate monitoring module 150 closer to the monitoring port 1211, reduce unnecessary travel, and increase monitoring accuracy, the slot 1212 in this embodiment is located on the side of the first housing 121 near the battery housing 110.

[0024] refer to Figures 2-6 In a specific embodiment, the ear-clip earphone 1000 further includes a light-shielding element 160, and the heart rate monitoring module 150 includes a circuit board 151, a light-emitting element 152, and a photosensitive element 153. The circuit board 151 is inserted into a slot 1212, and the light-emitting element 152 and the photosensitive element 153 are both mounted on the side of the circuit board 151 facing the monitoring port 1211. The light-emitting element 152 is used to emit light toward the user's skin. The photosensitive element 153 is used to receive light reflected back from the user's skin. The light-shielding element 160 is at least partially disposed between the light-emitting element 152 and the photosensitive element 153.

[0025] The light-shielding element 160 can be made of opaque EVA cotton, or black silicone or other colored opaque silicone to ensure effective light blocking. This embodiment does not limit the material; any opaque material will suffice.

[0026] By implementing this embodiment, the light emitted by the light-emitting element 152 can be effectively prevented from directly escaping to the photosensitive element 153, thus avoiding optical crosstalk and improving the monitoring accuracy of the heart rate monitoring module 150.

[0027] Specifically, the light-emitting element 152 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 153 can receive the reflected light. Since the heartbeat causes changes in the blood volume in the skin, the increase in blood volume increases the amount of light absorption and reduces the amount of light reflection. Therefore, the heart rate can be determined based on the light received by the photosensitive element 153.

[0028] More specifically, the light-emitting element 152 can be a light-emitting diode that can emit green or red light, and the photosensitive element 153 can be a photodiode or a photoresistor; this embodiment is not limited to these two types of elements.

[0029] refer to Figure 2 and Figure 3 In the specific embodiment described above, the light-shielding member 160 includes a first light-shielding portion 161 and a second light-shielding portion 162. The first light-shielding portion 161 is disposed between the light-emitting member 152 and the photosensitive member 153. The second light-shielding portion 162 is disposed on the side of the light-emitting member 152 and the photosensitive member 153 facing the second housing 122, and is connected to the first light-shielding portion 161.

[0030] The first light-shielding part 161 can prevent the light emitted by the light-emitting element 152 from directly escaping to the photosensitive element 153, thus avoiding optical crosstalk and improving the monitoring accuracy of the heart rate monitoring module 150. The second light-shielding part 162 can cover the side of the light-emitting element 152 and the light-shielding part 160 facing the second housing 122, so as to prevent the light emitted by the light-emitting element 152 from escaping towards the second housing 122 and to avoid stray light interference from the direction of the second housing 122, thereby improving the monitoring accuracy of the heart rate monitoring module 150.

[0031] refer to Figure 1 and Figure 6 In some embodiments, the ear clip-on earphone 1000 further includes a lens 170, which is installed at the monitoring port 1211. The light shield 160 is a flexible light shield 160, which is sandwiched between the lens 170 and the circuit board 151 so that the circuit board 151 is pressed against the groove wall of the slot 1212.

[0032] Specifically, lens 170 can prevent external dust and pollutants from entering the speaker housing 120 through monitoring port 1211 and contaminating the heart rate monitoring module 150, thus providing a certain degree of protection for the heart rate monitoring module 150. The light-shielding member 160 is a flexible light-shielding member, so it can generate elasticity through compression, causing the circuit board 151 to press firmly against the slot wall of slot 1212, achieving not only the fixation of the circuit board 151 but also ensuring the light-shielding effect.

[0033] It should be noted that the light-shielding component 160 can be made of opaque EVA cotton, or black silicone or other colored opaque silicone. This embodiment does not limit it, as long as it is a flexible and opaque material. This not only ensures effective light isolation, but also allows the light-shielding component 160 to have a certain deformation capability.

[0034] In a specific embodiment, a first injection layer (not shown in the figure) is also provided inside the first housing 121, and the first injection layer is connected to the first housing 121, the circuit board 151, the light shield 160 and the lens 170.

[0035] It should be noted that the first adhesive layer is formed by the curing of the injected adhesive, hence the name "first adhesive layer".

[0036] By implementing this embodiment, the connection stability of the heart rate monitoring module 150, the light shield 160, and the lens 170 can be improved by utilizing the first adhesive layer.

[0037] refer to Figure 6 In some embodiments, the clip-on earphone 1000 further includes a mainboard 180, a battery 190, a first wire 210, and a second wire 220. The mainboard 180 is housed within the battery casing 110. The first wire 210 passes through the elastic arm 130, with one end soldered to the mainboard 180 and the other end soldered to the circuit board 151. The second wire 220 passes through the elastic arm 130, with one end soldered to the mainboard 180 and the other end soldered to the sound-generating unit 140. The battery 190 is housed within the battery casing 110 and electrically connected to the mainboard 180, so that the circuit board 151 and the sound-generating unit 140 can obtain power from the battery 190 through the mainboard 180.

[0038] This embodiment demonstrates a specific implementation method for electrically connecting the circuit board 151 and the sound-generating unit 140 to the main board 180 inside the battery housing 110. Specifically, a first wire 210 is passed through the elastic arm 130, allowing one end of the first wire 210 to enter the battery housing 110 and be soldered to the main board 180, and the other end to enter the speaker housing 120 and be soldered to the circuit board 151. A second wire 220 is passed through the elastic arm 130, allowing one end of the second wire 220 to enter the battery housing 110 and be soldered to the main board 180, and the other end to enter the speaker housing 120 and be soldered to the sound-generating unit 140.

[0039] refer to Figure 3 and Figure 5 In a specific embodiment, the circuit board 151 has a soldering part 1511 on the side facing away from the monitoring port 1211, and the slot 1212 has a notch 12121 on the slot wall facing away from the monitoring port 1211. The soldering part 1511 is exposed by the notch 12121, and the first wire 210 is soldered to the soldering part 1511.

[0040] This embodiment illustrates a specific example of soldering the first conductor 210 to the circuit board 151. Since the circuit board 151 needs to be soldered to the first conductor 210, a soldering portion 1511 is provided on the circuit board 151 for soldering the first conductor 210. To shorten the first conductor 210 as much as possible and reduce the weight of the ear clip-on earphone 1000, in this embodiment, the soldering portion 1511 is located on the side of the slot 1212 facing away from the monitoring port 1211. Furthermore, to expose the soldering portion 1511 and reduce the weight of the ear clip-on earphone 1000, a notch 12121 is provided on the slot wall.

[0041] refer to Figure 6In some embodiments, one side of the motherboard 180 abuts against the inner wall of the battery housing 110. The ear clip-on earphone 1000 also includes a battery mounting base 230 and a flexible pad 240. The battery mounting base 230 is mounted on the other side of the motherboard 180, and the battery 190 is mounted on the side of the battery mounting base 230 facing away from the motherboard 180. One side of the flexible pad 240 abuts against the side of the battery 190 facing away from the motherboard 180, and the other side abuts against the inner wall of the battery housing 110, so as to secure the motherboard 180, the battery 190, and the battery mounting base 230 within the battery housing 110.

[0042] This embodiment illustrates a specific implementation method for fixing the motherboard 180, battery 190, and battery mounting bracket 230 within the battery housing 110. Specifically, a deformable flexible pad 240 is used to press the motherboard 180, battery 190, and battery mounting bracket 230 firmly against the battery housing 110. One side of the flexible pad 240 can apply a force to the inner wall of the battery housing 110, and the other side can apply a force to the battery 190. The force is transmitted to the motherboard 180 through the battery mounting bracket 230. Because the motherboard 180 abuts against the inner wall of the battery housing 110, the battery housing 110 provides a counterforce, causing the battery 190, battery mounting bracket 230, and motherboard 180 to be pressed firmly against the battery housing 110 by the flexible pad 240.

[0043] In addition, when the ear clip-on headphones 1000 are dropped or encounter other situations that cause the battery case 110 to be impacted by external force, the flexible pad 240 can play a buffering role through deformation, providing protection for the motherboard 180, battery 190 and battery mounting bracket 230 to a certain extent.

[0044] The flexible pad 240 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 190, the battery mounting base 230, and the motherboard 180 tightly against the battery case 110 through deformation.

[0045] refer to Figure 7 and Figure 8 In a specific embodiment, a support block 111 is provided on the inner wall of the battery casing 110. The support block 111 is located on the side of the battery casing 110 away from the monitoring port 1211. A first pin 1111 is provided on the support block 1111. One side of the main board 180 abuts against the support block 111, and a first socket 181 is provided on the main board 180. The first pin 1111 is inserted into the first socket 181.

[0046] This embodiment illustrates a specific implementation of a limiting installation of the motherboard 180. Specifically, when the motherboard 180 abuts against the support block 111, the first pin 1111 on the support block 111 will be inserted into the first socket 181 of the motherboard 180, thereby constraining the position of the motherboard 180.

[0047] Alternatively, in another embodiment, the motherboard 180 can be glued to the inner wall of the battery case 110, which can also achieve the limiting installation of the motherboard 180.

[0048] Of course, it is understandable that in the embodiment where the motherboard 180 is installed by using the first pin 1111 in conjunction with the first socket 181, some glue can also be applied to the support block 111 to increase the connection stability of the motherboard 180.

[0049] refer to Figure 7 and Figure 8 In some embodiments, the battery mounting base 230 is provided with a second pin 231 on the side facing away from the battery 190, and the main board 180 is provided with a second socket 182, and the second pin 231 is inserted into the second socket 182.

[0050] This embodiment illustrates a specific implementation of a battery mounting base 230 with a limiting installation method. Specifically, the second pin 231 on the battery mounting base 230 is inserted into the second socket 182 of the motherboard 180, thereby constraining the position of the battery mounting base 230.

[0051] Alternatively, in another embodiment, the battery mounting base 230 can be glued to the motherboard 180, which can also achieve the limited installation of the battery mounting base 230.

[0052] Of course, it is understandable that in the embodiment where the battery mounting base 230 is installed by using the second pin 231 in conjunction with the second socket 182, some glue can be applied at the contact point between the battery mounting base 230 and the motherboard 180 to increase the connection stability of the battery mounting base 230.

[0053] refer to Figure 8 In some embodiments, the battery mounting base 230 has a second mounting groove 232 on the side away from the motherboard 180, and the battery 190 is limited to be installed in the second mounting groove 232.

[0054] The second mounting slot 232 can provide a clear mounting position for the battery 190, which can effectively prevent the battery 190 from being installed off-center, resulting in high consistency of the manufactured products.

[0055] In some embodiments, the transmittance of the lens 170 is greater than 90%, which can avoid significant loss of light signals when they enter and exit the lens 170, and provide a high-quality data foundation for the heart rate monitoring module 150.

[0056] In some embodiments, the lens 170 is a Fresnel lens 170. The Fresnel lens 170 has excellent light-gathering ability and is thinner and lighter than the traditional convex lens 170. Therefore, the lens 170 in this embodiment is a Fresnel lens 170.

[0057] In a specific embodiment, lens 170 is made of acrylic, a low-cost and easily processed plastic that is ideal for manufacturing Fresnel lens 170.

[0058] refer to Figure 9 In some embodiments, the second housing 122 has a first mounting groove 1221 on the side facing the first housing 121, and the sound unit 140 is mounted in the first mounting groove 1221. The ear clip earphone 1000 also includes a second injection layer (not shown in the figure), which surrounds the sound unit 140 and is connected to the sound unit 140 and the groove wall of the first mounting groove 1221.

[0059] This embodiment illustrates a specific implementation of a sound-generating unit 140 installed in a second housing 122. Specifically, a first mounting groove 1221 is provided on the side of the second housing 122 facing the first housing 121, the sound-generating unit 140 is installed in the first mounting groove 1221, and the sound-generating unit 140 is connected to the groove wall of the first mounting groove 1221 by a second injection layer.

[0060] It should be noted that the second adhesive layer is formed by the curing of the injected adhesive, hence the name "second adhesive layer".

[0061] 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. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
