[0002] As people pay more and more attention to their health, more and more users are choosing to wear open-back headphones.

[0003] In open-back earphones, the battery section typically uses multiple wires soldered onto the motherboard to electrically connect the battery section and the sound unit. However, a large number of wires can easily affect the wireless signal at the battery section, affecting the communication distance and stability between the earphone and other devices. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a battery unit and an ear clip-on earphone to reduce the impact of the wiring harness on the motherboard on the wireless signal reception at the battery unit.

[0005] To achieve the above objectives, one aspect of this application provides a battery unit, comprising:

[0006] A motherboard, wherein a wire harness soldering area is formed on one side of the motherboard along a first direction;

[0007] The antenna is connected to the motherboard;

[0008] A conductive element, a portion of which is disposed in the wire harness welding area, and another portion of which extends along the first direction to conduct the induced current generated in the wire harness welding area to the motherboard on the other side of the motherboard along the first direction relative to the wire harness welding area.

[0009] In some embodiments, the antenna is disposed on the side of the motherboard away from the conductive member along a second direction, wherein the first direction intersects the second direction.

[0010] In some embodiments, the conductive element is bent at one end away from the wire harness welding area along the first direction and extends in the second direction away from the antenna.

[0011] In some embodiments, the battery section includes a battery disposed on one side of the motherboard relative to the antenna, a portion of the conductive member passing through the battery and the motherboard, and a curved portion of the conductive member disposed on the circumferential side of the battery.

[0012] In some embodiments, the conductive member includes a connecting portion, a bending portion, and an extension portion. One end of the connecting portion is connected to the wire harness welding area, and the other end of the connecting portion extends along the first direction and is disposed between the battery and the motherboard. One end of the bending portion is connected to the end of the connecting portion away from the wire harness welding area along the first direction, and the other end of the bending portion extends along the second direction away from the antenna. One end of the extension portion is connected to the bending portion, and the other end of the extension portion extends circumferentially along the battery and is attached to the peripheral sidewall of the battery.

[0013] In some embodiments, the motherboard has a wiring harness mounting portion and a charging terminal on opposite sides along a third direction, and the projection area of ​​the extension portion along the second direction is located between the connecting portion and the wiring harness mounting portion.

[0014] In some embodiments, the ratio of the dimension of the extension to the circumference of the battery ranges from 0.15 to 0.3.

[0015] In some embodiments, the width of the conductive element is between 2 mm and 3 mm.

[0016] In some embodiments, the conductive element includes at least two insulating layers and a conductive layer sandwiched between the two insulating layers.

[0019] In the battery section of this application embodiment, a portion of the conductive member is disposed in the wire harness welding area, and another portion of the conductive member extends along a first direction to conduct the induced current generated in the wire harness welding area to the other side of the main board along the first direction relative to the wire harness welding area. Thus, one end of the conductive member forms an electrical connection with the wire harness welding area, and the other end extends to the other side along the first direction relative to the wire harness welding area. This disperses the electromagnetic wave radiation originally located in the wire harness welding area to the other side along the first direction relative to the wire harness welding area, thereby reducing the electromagnetic wave radiation in the wire harness welding area, improving the direction of electromagnetic signals, reducing the impact of the wire harness welding area on antenna signals, improving antenna performance, and enhancing production efficiency and consistency.

[0028] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0029] In the description of the embodiments of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0031] As people pay more and more attention to their health, more and more users are choosing to wear open-back headphones.

[0032] In open-back earbuds, the battery compartment typically uses multiple wires soldered to the mainboard's wire harness soldering area to electrically connect the battery compartment and the sound-emitting part. Due to the conductive material inside the wire harness, it has a certain degree of conductivity or magnetism, which can scatter or absorb wireless signals, affecting the electromagnetic field. Furthermore, the numerous solder joints in the wire harness soldering area result in stronger electromagnetic radiation at that location, thus affecting antenna performance and impacting the communication distance and stability between the earbuds and other devices.

[0033] Based on the above, a first aspect of this application provides a battery unit 10. Please refer to... Figures 1 to 6 The battery unit 10 includes a main board 11, an antenna 12, and a conductive member 13. A wire harness soldering area 11a is formed on one side of the main board 11 along a first direction. The antenna 12 is connected to the main board 11. A portion of the conductive member 13 is disposed in the wire harness soldering area 11a, and another portion of the conductive member 13 extends along the first direction to conduct the induced current generated in the wire harness soldering area 11a to the other side of the main board 11 along the first direction opposite to the wire harness soldering area 11a.

[0034] It should be noted that the battery unit 10 in this application can be any type of headphone battery unit 10. Typically, in addition to the battery unit 10, the headphone also includes a sound-emitting unit 20, which is electrically connected to the battery unit 10, and the battery unit 10 can provide power for the sound-emitting unit 20 to vibrate and emit sound waves.

[0035] For example, the battery unit 10 also includes a housing 15, which has a connection port 15a for connecting to the sound-generating unit 20. The wiring harness of the sound-generating unit 20 enters the housing 15 from the connection port 15a and is electrically connected to the wiring harness soldering area 11a on the main board 11.

[0036] The first direction can be the length direction of the motherboard 11.

[0037] The motherboard 11 can be a printed circuit board (PCB), which is an important electronic component, a support for electronic components, and a carrier for the electrical interconnection of electronic components.

[0038] Antenna 12 can be a flexible printed circuit board (FPC), which is a highly reliable and extremely flexible printed circuit board made with polyimide or polyester film as the substrate. It features high wiring density, light weight, thinness, and good bendability. Antenna 12 can be a copper area on the flexible circuit board. Antenna 12 can be used to receive wireless signals, thereby enabling communication between the headset and other devices.

[0039] At least a portion of the conductive element 13 is a conductor, thereby enabling the conduction of induced current.

[0040] A wire harness soldering area 11a is formed on one side of the motherboard 11 along the first direction. The wire harness soldering area 11a is used to connect the wire harness from the sound-emitting part 20 of the earphone to realize the electrical connection between the motherboard 11 and the sound-emitting part 20. In related technologies, because there are many solder joints in the wire harness soldering area 11a, the induced current is more concentrated, which leads to stronger electromagnetic wave radiation in the wire harness soldering area 11a, which can easily interfere with the antenna 12 signal.

[0041] Antenna 12 is connected to motherboard 11, meaning that antenna 12 is located inside battery section 10 and is signal-connected to motherboard 11.

[0042] It is understandable that the motherboard 11 and the antenna 12 can be connected together to form a dipole antenna. Since the motherboard 11 itself has a conductor part, the motherboard 11 can be regarded as half a dipole antenna, which can generate radiated electromagnetic fields due to applied time-varying voltage or time-varying current, or generate induced current due to electromagnetic fields in the environment.

[0043] A portion of the conductive element 13 is disposed in the wire harness welding area 11a, and the other portion of the conductive element 13 extends along the first direction to conduct the induced current generated in the wire harness welding area 11a to the other side of the motherboard 11 along the first direction relative to the wire harness welding area 11a. Thus, one end of the conductive element 13 is electrically connected to the wire harness welding area 11a, and the other end extends to the other side along the first direction relative to the wire harness welding area 11a. This disperses the electromagnetic wave radiation that was originally concentrated in the wire harness welding area 11a to the other side along the first direction relative to the wire harness welding area 11a, thereby reducing the electromagnetic wave radiation in the wire harness welding area 11a and improving the direction of the electromagnetic signal.

[0044] When assembling clip-on headphones, the wiring harness layout is usually done manually to mitigate the impact of the soldered area on the antenna's electromagnetic signal. However, manual wiring is prone to inconsistencies, leading to varying degrees of impact on the antenna from the battery section's soldered area in different headphones, resulting in inconsistent product quality. Furthermore, the limited space and difficulty in handling wiring during assembly contribute to low production efficiency.

[0045] This application, by setting a conductive element 13, with one end of the conductive element 13 electrically connected to the wire harness welding area 11a and the other end extending to the other side of the wire harness welding area 11a along the first direction, can improve the influence of the wire harness welding area 11a on the antenna 12 signal, improve the performance of the antenna 12, eliminate the need for manual wire management, and thus improve production efficiency and consistency.

[0046] In the battery unit 10 of this application embodiment, a portion of the conductive member 13 is disposed in the wire harness welding area 11a, and the other portion of the conductive member 13 extends along a first direction to conduct the induced current generated in the wire harness welding area 11a to the other side of the main board 11 along the first direction relative to the wire harness welding area 11a. Thus, one end of the conductive member 13 is electrically connected to the wire harness welding area 11a, and the other end extends to the other side along the first direction relative to the wire harness welding area 11a. This disperses the electromagnetic wave radiation originally located in the wire harness welding area 11a to the other side along the first direction relative to the wire harness welding area 11a, thereby reducing the electromagnetic wave radiation in the wire harness welding area 11a, improving the direction of electromagnetic signals, reducing the influence of the wire harness welding area 11a on the antenna 12 signal, improving the performance of the antenna 12, and enhancing production efficiency and consistency.

[0047] In some embodiments, please refer to Figures 2 to 6 The antenna 12 is located on the side of the main board 11 facing away from the conductor 13 along the second direction. The first direction intersects the second direction.

[0048] For example, the first direction is perpendicular to the second direction.

[0049] For example, the second direction may be the thickness direction of the battery section 10.

[0050] It should be noted that the dimensions of different parts in the three directions are different in the same absolute coordinate system. Generally, the length, width and thickness of an object are determined according to the dimensions of the object extending in the three directions, with length > width > thickness.

[0051] In this embodiment, the motherboard 11 and the battery section 10 are aligned in both length and thickness directions.

[0052] Antenna 12 is disposed on the side of motherboard 11 away from conductor 13 along the second direction. That is, conductor 13 is on one side of the entire dipole antenna 12 formed by motherboard 11 and antenna 12 along the second direction. By disposing of conductor 13 on one side of dipole antenna 12 along the second direction, the electromagnetic field distribution on the side of conductor 13 can be improved, the electromagnetic wave radiation of wire harness and wire harness welding area 11a can be reduced, and the stability and reliability of signal reception or transmission on the side of antenna 12 can be improved.

[0053] In some embodiments, please refer to Figures 2 to 6 The conductive element 13 is bent at one end away from the wire harness welding area 11a in the first direction and extends in the second direction away from the antenna 12.

[0054] Thus, the conductor 13 is longer at the end away from the wire harness welding area 11a along the first direction, which can improve the effect of the conductor 13 in dispersing the radiation of the wire harness welding area 11a.

[0055] In some embodiments, please refer to Figures 2 to 6 The battery section 10 includes a battery 14. The battery 14 is disposed on the side of the main board 11 opposite to the antenna 12. A portion of the conductive member 13 passes between the battery 14 and the main board 11. The bent portions 132 of the conductive member 13 are disposed on the circumferential side of the battery 14.

[0056] Battery 14 can be a lithium battery 14, and there is no restriction on this.

[0057] For example, the battery unit 10 also includes a buffer 16, which is disposed between the battery 14 and the motherboard 11. The buffer 16 can be, for example, foam, which can isolate the battery 14 from the motherboard 11, prevent the battery 14 from directly contacting the motherboard 11, and improve the safety of the battery unit 10.

[0058] The battery 14 is located on the side of the motherboard 11 opposite to the antenna 12. This means that the battery 14 is located on the side of the motherboard 11 away from the antenna 12 along the second direction. In other words, the conductive member 13 and the battery 14 are both located on the same side of the motherboard 11. This can improve the compactness of the battery section 10 structure and increase space utilization.

[0059] Part of the conductive member 13 passes between the battery 14 and the motherboard 11. That is, after the conductive member 13 connects to the wire harness welding area 11a, it passes between the battery 14 and the motherboard 11 and reaches the side of the battery 14 away from the wire harness welding area 11a in the first direction.

[0060] The bent portion 132 of the conductive member 13 is disposed on the circumferential side of the battery 14. That is, the end of the conductive member 13 away from the wire harness welding area 11a along the first direction extends in the second direction away from the antenna 12 and extends to the circumferential side of the battery 14. This facilitates the fixing of the conductive member 13 to the battery 14 at the end away from the wire harness welding area 11a and makes assembly more convenient.

[0061] In some embodiments, please refer to Figures 2 to 6The conductive member 13 includes a connecting portion 131, a bending portion 132, and an extension portion 133. One end of the connecting portion 131 is connected to the wire harness welding area 11a, and the other end of the connecting portion 131 extends along a first direction and is disposed between the battery 14 and the main board 11. One end of the bending portion 132 is connected to the end of the connecting portion 131 away from the wire harness welding area 11a along the first direction, and the other end of the bending portion 132 extends along a second direction away from the antenna 12. One end of the extension portion 133 is connected to the bending portion 132, and the other end of the extension portion 133 extends circumferentially along the battery 14 and is attached to the peripheral sidewall of the battery 14.

[0062] One end of the bent portion 132 is connected to one end of the connecting portion 131 away from the wire harness welding area 11a along the first direction, and the other end of the bent portion 132 extends away from the antenna 12 along the second direction. That is, the connecting portion 131, the bent portion 132 and the extension portion 133 are connected in sequence, and the bent portion 132 may be the part of the conductor 13 that extends along the second direction.

[0063] One end of the extension 133 is connected to the bending part 132, and the other end of the extension 133 extends along the circumference of the battery 14 and is attached to the peripheral sidewall of the battery 14. In other words, the extension 133 is designed to conform to the peripheral sidewall of the battery 14, so as to achieve a complete fit, which is conducive to the connection and fixation of the extension 133 and the battery 14.

[0064] In some embodiments, please refer to Figures 3 to 6 The motherboard 11 has a wire harness mounting portion 11b and a charging terminal 11c on opposite sides along the third direction. Projected along the second direction, the projection area of ​​the extension 133 is located between the connecting portion 131 and the wire harness mounting portion 11b.

[0065] It should be noted that the third direction can be the width direction of the motherboard 11.

[0066] The wire harness mounting section 11b is an area on the motherboard 11 used to place excess wire harnesses that are connected to the wire harness soldering area 11a. The wire harness mounting section 11b is located close to the connection port 15a of the housing 15 in a third direction. In this way, after the wire harness enters the housing 15 through the connection port 15a, it can be arranged close to the wire harness soldering area 11a, saving wire harnesses and reducing the space occupied by the wire harnesses.

[0067] The charging terminal 11c is located on the side of the housing 15 away from the connection port 15a along the third direction. One end of the charging terminal 11c is connected to the motherboard 11, and the other end is used to form an electrical connection with the outside world, thereby charging the battery 14.

[0068] Because of the conductive nature of the charging terminal 11c and its electrical connection with the positive terminal of the battery 14, the current on the conductor 13 will be affected. Since the wire harness mounting part 11b is full of wire harnesses and requires subsequent glue application, there is no space to arrange the extension part 133. Therefore, the extension part 133 is arranged between the connecting part 131 and the wire harness mounting part 11b and is located on the side of the battery 14 away from the wire harness welding area 11a along the first direction. This is more conducive to the arrangement of components inside the housing 15, can improve the assembly operation space, and is beneficial to assembly.

[0069] In some embodiments, please refer to Figures 3 to 5 The ratio of the size of the extension 133 to the circumference of the battery 14 is between 0.15 and 0.3.

[0070] For example, the ratio of the size of the extension 133 to the circumference of the battery 14 is 0.15, 0.18, 0.2, 0.22, 0.25, 0.28 or 0.3, etc., and is not limited here.

[0071] like Figure 5 As shown, the dimensions of the extension 133 are represented by Z.

[0072] Here, by limiting the ratio range between the size of the extension 133 and the circumference of the battery 14, the length of the conductive element 13 within the extension 133 can be kept within a suitable range. This results in better consistency of the signal performance of the antenna 12 in the final assembled product, a significant improvement in the average performance, and a substantial improvement in the lower limit objective data. Compared to related technologies that use manual wiring to reduce the impact of the wiring harness on the signal performance of the antenna 12, this method is more efficient and offers better controllability.

[0073] In some embodiments, please refer to Figures 3 to 6 The width of the conductive element 13 is between 2mm and 3mm.

[0074] For example, the width of the conductive element 13 can be 2mm, 2.2mm, 2.5mm, 2.8mm or 3mm, etc., and there is no limitation here.

[0075] Here, by limiting the width of the conductive element 13, the width of the conductive element 13 can be kept within a suitable range, resulting in better consistency in the signal performance of the final assembled antenna 12, a significant improvement in the average performance, and a substantial improvement in the lower limit objective data. Compared to related technologies that use manual cable management to reduce the impact of the cable bundle on the signal performance of the antenna 12, this method is more efficient and offers better controllability.

[0076] In some embodiments, the conductive element 13 includes at least two insulating layers and a conductive layer sandwiched between the two insulating layers.

[0077] The insulating layer is used to isolate the conductive layer from the external environment of the conductive component 13, preventing the current in the conductive layer from being directly discharged.

[0078] The conductive layer is used to conduct current or to generate induced current.

[0079] For example, the conductive layer may be made of copper.

[0080] The conductive element 13 only needs to be provided with at least two insulating layers and a conductive layer sandwiched between the two insulating layers. In this way, the conductive element 13 is in the form of a sheet, which can enhance the effect of the induced current generated in the welding area 11a of the wire harness, thereby improving the dispersion of electromagnetic wave radiation.

[0081] In other embodiments, the conductive element 13 may be a wire.

[0082] In some embodiments, the conductive element 13 is a flexible circuit board.

[0083] Here, the flexible circuit board that serves as the conductive element 13 can be a bare board without any other surface-mounted components.

[0084] Thus, the flexible circuit board has a certain degree of flexibility, which can fit with the battery 14, improve the compactness of the internal components of the battery section 10, and also facilitate assembly.

[0085] A second aspect of this application provides an ear clip-on earphone 100, please refer to... Figures 1 to 6 The clip-on earphone 100 includes a sound-generating part 20 and a battery part 10 as described above.

[0086] The battery unit 10 is placed behind the ear, and the sound-generating part 20 is placed in the concha cavity. The battery unit 10 and the sound-generating part 20 together form a clamp on the auricle.

[0087] The ear-clip headphone 100 also includes a connection unit 30, which connects the battery unit 10 and the sound-generating unit 20 and provides clamping force for the battery unit 10 and the sound-generating unit 20. The wiring harness is electrically connected to the mainboard 11 of the sound-generating unit 20 and the battery unit 10 respectively through the connection unit 30.

[0088] The ear clip-on earphone 100 provided in this application, based on the advantages of the battery part 10 mentioned above, has the characteristics of reducing electromagnetic wave radiation in the wire harness welding area 11a, improving the direction of electromagnetic signals, reducing the influence of the wire harness welding area 11a on the antenna 12 signal, improving the performance of the antenna 12, and enhancing production efficiency and consistency.

[0089] In one embodiment, radiation performance tests are performed on clip-on headphones without the added conductive element 13 and clip-on headphones 100 with the added conductive element 13 as described in this application, to obtain binaural head model data for both types of clip-on headphones. Here, binaural head model data refers to data used to simulate the acoustic characteristics of the human head and ears in order to achieve more realistic sound reproduction in recording and sound processing. This data typically includes the geometric dimensions, material properties, and acoustic characteristics of the head model.

[0090] The binaural head model data referenced here is divided into left and right ear measurements, specifically including CH (channel), TRP (Total Radiated Power), and TIS (Total Isotropic Sensitivity). TRP measures the total power radiated by the transmitter antenna in all directions, while TIS measures the sensitivity of the receiver antenna in receiving signals in all directions. A higher TRP indicates greater transmitter power and a wider signal coverage area. A higher TIS indicates higher receiver antenna sensitivity and a weaker received signal.

[0091] For example, the head model data of the left earpiece of the ear clip-on earphone without the added conductive element 13 are as follows: under CH0, TRP is -5.55dBm and TIS is -75.7dBm; under CH39, TRP is -4.95dBm and TIS is -76.13dBm; under CH78, TRP is -5.6dBm and TIS is -75.27dBm.

[0092] Data for the right earpiece head model of the clip-on earphone without the added conductive element 13: At CH0, TRP is -1.84dBm and TIS is -79.57dBm; at CH39, TRP is -1.5dBm and TIS is -79.59dBm; at CH78, TRP is -2.19dBm and TIS is -78.53dBm.

[0093] This application adds the following data for the left earphone head model of the ear clip-on earphone 100 with conductive element 13: under CH0, TRP is -1.9dBm and TIS is -80.73dBm; under CH39, TRP is 0.05dBm and TIS is -80.89dBm; under CH78, TRP is -1.26dBm and TIS is -79.65dBm.

[0094] This application adds the following head model data for the right earpiece of the ear clip-on earphone 100 with conductive element 13: under CH0, TRP is -2.17dBm and TIS is -79.53dBm; under CH39, TRP is -0.9dBm and TIS is -80.55dBm; under CH78, TRP is -1.75dBm and TIS is -79.67dBm.

[0095] It can be seen that the head model data of the left ear and the right ear without the addition of the conductive element 13 are very different. However, the ear clip-on earphone 100 with the addition of the conductive element 13 in this application has relatively stable head model data of the left and right ears and both have improved consistency, with little difference between the left and right ears.

[0096] The head mold data of the right earphone without the added conductive component 13 shows that the data without the added conductive component 13 is similar to the head mold data of the right earphone with the added conductive component 13 in this application. However, the earphone without the added conductive component 13 requires precise cable management during the assembly process, and the consistency is poor. The assembly efficiency is low and it is not suitable for mass production.

[0097] Without the addition of the conductive element 13, the TIS data of the ear clip-on headphones can reach -75dBm to -79dBm through cable management. However, the ear clip-on headphones 100 provided in this application with the addition of the conductive element 13 can improve the TIS data to -79dBm to -80dBm, increasing the upper limit by 1dBm while ensuring consistency. This increases mass production capability, reduces cable management steps, improves assembly efficiency, improves the RF station defect situation, enhances quality, and meets users' requirements for Bluetooth stability of the ear clip-on headphones 100.

[0098] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this application, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
