[0026] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] The circuit board of existing OWS headphones is usually set on one side of the speaker, and the speaker is controlled by the circuit board to achieve sound playback. This design is unreasonable. The circuit board and the speaker are close to each other, and the circuit board is easy to interfere with the speaker, affecting signal transmission; it also causes uneven weight distribution in the headphones, affecting wearing comfort.

[0028] Based on this, the present application provides an OWS headset.

[0029] Example

[0030] like Figure 1-Figure 6 As shown, an OWS headset comprises a housing, wherein the housing comprises a control cavity 11, an ear hook 13 and a sound playing cavity 14 which are connected to each other;

[0031] The sound-playing cavity 14 is provided with a speaker 6 and an antenna FPC7, and the antenna FPC7 is provided on one side of the speaker 6. The control cavity 11 is provided with a circuit board 3, and the antenna FPC7 is electrically connected to the circuit board 3 through a radio frequency line 8. A plurality of sound output positions 15 are provided on the wall of the sound-playing cavity 14. It should be noted that the sound output position 15 of the present application is the speaker mouth, and the speaker of the present application adopts a 1510 speaker, for example, it can be NR1510, and NR1510 has a speaker with a slim shape design, and its height is relatively low, which is suitable for application environments with limited space, and at the same time provides good sound quality performance, so that the earphone of the present application has a slim shape and good sound quality. The speaker 6 is electrically connected to the circuit board 3 through a speaker line 5. In actual applications, the speaker line 5 and the radio frequency line 8 have the same direction, and are both connected to the circuit board 3 after passing through the ear hook 13.

[0032] In actual use, the sound-reproducing cavity 14 is located on one side of the user's auricle, corresponding to the user's external auditory canal. The sound-reproducing cavity 14 emits sound through a plurality of sound output positions 15, that is, the sound generated by the speaker 6 is transmitted to the outside world or the consumer's ear through the sound output positions 15. This design can overcome the defect that the antenna in the existing earphone is located on the back of the auricle, which is easily blocked by the auricle and the user's head, making the signal of the earphone easily interfered.

[0033] The control cavity 11 is located at the back of the auricle. When the user wears it, the control cavity 11 is located between the auricle and the head of the user.

[0034] The OWS headset of the present application uses an antenna FPC for signal transmission, which has the following advantages:

[0035] The FPC antenna is flexible and can fit into the compact space inside the headset, and is easy to shape. This allows for better layout of circuits and components within a limited space during headset design and manufacturing, improving the flexibility and freedom of the overall design; in addition, the FPC can integrate more components, such as resistors, capacitors, inductors, etc., thereby reducing the overall size and weight. This helps to improve the comfort and portability of the headset.

[0036] Secondly, FPC antennas have high reliability. Since FPC material is relatively soft and resistant to bending, it can reduce the risk of wear and breakage during the use of headphones. At the same time, FPC antennas can also be customized according to the specific structure of the headphones to meet the needs of different models of headphones.

[0037] In addition, FPC antennas also have good electrical properties. Compared with other types of antennas, FPC antennas can achieve higher signal transmission efficiency while maintaining lower loss, allowing the headset to achieve a longer transmission distance and more stable connection.

[0038] In summary, the antenna FPC of the present application is used in OWS headphones and has the advantages of strong adaptability, high reliability, and good electrical performance.

[0039] The antenna FPC7 of the OWS headset is arranged in the sound-playing cavity 14, and the antenna FPC7 is connected to the circuit board 3 through the radio frequency line 8. There is a long distance between the antenna FPC7 and the circuit board 3. The antenna FPC7 and the circuit board 3 are arranged separately, so that the overall structure layout of the headset is reasonable and the weight distribution is uniform, which can bring a comfortable wearing experience to the user. In addition, the antenna FPC7 antenna is flexible and can adapt to the compact space inside the headset. The antenna FPC7 antenna also has high reliability and can achieve high signal transmission efficiency while maintaining low loss; and the antenna FPC7 is located in the sound-playing cavity 14, and is located in front of the auricle when worn, which helps to enhance the signal of the headset, reduce interference with signal transmission, and improve the sound quality of the headset. The housing also includes a battery cavity 12, which is located between the control cavity 11 and the ear hook 13. A battery 4 is arranged in the battery cavity 12, and the battery 4 is electrically connected to the circuit board 3.

[0040] More specifically, the housing includes a bottom shell 19 and a shell cover 18. One side of the bottom shell 19 is provided with an opening, and the shell cover 18 is snapped into the opening of the bottom shell 19. The antenna FPC7, the battery 4 and the circuit board 3 are all arranged in the bottom shell 19, and a Bluetooth module is arranged on the circuit board 3. The Bluetooth module is used to realize the wireless connection between the headset and the mobile terminal. The Bluetooth module can adopt an existing Bluetooth module,

[0041] The control chamber 11, the battery chamber 12, the ear hook 13 and the sound-playing chamber 14 are four different parts of the housing 1. The control chamber 11, the battery chamber 12, the ear hook 13 and the sound-playing chamber 14 are all located in the space formed by the bottom housing 19 and the housing cover 18 and are interconnected.
