[0026] The utility model provides a wireless headset, please refer to Figure 1 and Figure 2 , which includes a front shell 1, a middle shell 2, a rear shell 3, a partition 4, a sound module 5, a battery module 6, a mainboard 7 and an FPC component 8. The front shell 1 is detachably connected to the middle shell 2 to form a first accommodating cavity, and the rear shell 3 is detachably connected to the middle shell 2 to form a second accommodating cavity 22.

[0027] Among them, a mouthpiece 12 is provided at the end of the front shell 1, and the front shell 1 is used to fit the ear cavity of the user; the middle shell 2 is irregular in shape, and the side where the middle shell 2 is connected to the front shell 1 is in a cavity shape that is approximately bowl-shaped, and the side where the middle shell 2 is connected to the rear shell 3 is in a flat rod cavity shape; the rear shell 3 is in the shape of a cover plate, which covers the middle shell 2 and together with one side of the middle shell 2 constitutes the rod part of the earphone. Through the assembly connection between the front shell 1, the middle shell 2 and the rear shell 3, the space inside the wireless earphone is enclosed and formed, that is, the first accommodating cavity and the second accommodating cavity 22 together constitute the space inside the wireless earphone.

[0028] The sound module 5 is a speaker of the wireless headset, which is used to generate audio for the user to listen to. A number of electronic components are arranged on the main board 7, which are mainly used to control the wireless headset. The battery module 6 is mainly used to provide an energy source for the operation of the wireless headset. The FPC component 8 is a flexible circuit board, which is mainly used to connect the electronic components inside the wireless headset with the battery module 6, so that the battery module 6 can provide power for the electronic components inside the wireless headset.

[0029] Specifically, the partition 4 is arranged in the first accommodating cavity to divide the first accommodating cavity into a first cavity 11 and a second cavity 21; the sound module 5 is arranged in the first cavity 11, the battery module 6 is arranged in the second cavity 21, and a magnetic component 9 is also arranged in the second cavity 21. The main board 7 is arranged in the second accommodating cavity 22, and the FPC component 8 passes through the second accommodating cavity 22, the second cavity 21 and the first cavity 11 in sequence to electrically connect the main board 7 and the sound module 5 to the battery module 6.

[0030] It is easy to understand that the partition 4 is arranged in the first accommodating cavity, and the first accommodating cavity can be divided into a first cavity 11 and a second cavity 21, so that the sound module 5 and the battery module 6 can be arranged in two relatively independent accommodating spaces respectively, which can effectively reduce the mutual interference between the sound module 5 and the battery module 6, and reduce the mutual interference between the sound module 5 and the magnetic member 9. At the same time, the sound module 5 is arranged in the first cavity 11, and by adjusting the position of the sound module 5 in the first cavity 11, the effect of the audio output of the wireless headset can be adjusted to a certain extent. The battery module 6 is arranged in the second cavity 21, and the partition 4 can provide a fixed part for supporting and limiting the battery module 6, which can reduce the number of fixed parts of the battery module 6 to a certain extent, thereby optimizing the internal space layout of the wireless headset. The electrical connection between the sound module 5, the main board 7 and the battery module 6 is realized through the FPC member 8, which can improve the compatibility of the spatial distribution of the electronic components inside the wireless headset to a certain extent, thereby optimizing the internal space layout of the wireless headset.

[0031] This embodiment optimizes the stacking arrangement of the electronic components inside the wireless headset by setting the separator 4 and the FPC component 8, thereby optimizing the layout of the internal space of the wireless headset, reducing the volume of the wireless headset, and improving the user experience.

[0032] For further information, please refer to Figure 3 In one embodiment, the FPC component 8 includes a first fixing portion 81, a first electrical connecting portion 82, a second electrical connecting portion 83, a second fixing portion 84 and a third electrical connecting portion 85; the first electrical connecting portion 82, the second electrical connecting portion 83 and the second fixing portion 84 are all connected to the first fixing portion 81, and the third electrical connecting portion 85 is connected to the second fixing portion 84.

[0033] Among them, the first fixing part 81 and the second fixing part 84 are both the fixing part and the extended connection part of the FPC part 8, which mainly serve to fix the FPC part 8 in the internal space of the wireless headset, and are also the origin of the extension of the electrical connection part of the FPC part 8. The first electrical connection part 82, the second electrical connection part 83 and the third electrical connection part 85 are mainly used for the conductive connection between the FPC part 8 and the internal electronic components of the wireless headset. Specifically, the first electrical connection part 82 is used to electrically connect the motherboard 7, the second electrical connection part 83 is used to electrically connect the battery module 6, and the third electrical connection part 85 is used to electrically connect the sound module 5. It is easy to understand that the specific shape of the FPC part 8 depends on the space conditions of the wireless headset and the specific stacking of the electronic components.

[0034] For further information, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In one embodiment, the separator 4 includes a main body 41 and an engaging portion 42 formed along the main body 41 and recessed toward the second cavity 21. The main body 41 is provided with a first connecting groove 43 connecting the second cavity 21 and the first cavity 11. Furthermore, the second cavity 21 is provided with a second connecting groove 23 connecting the second cavity 21 and the second accommodating cavity 22.

[0035] Among them, the interlocking portion 42 is used to combine the partition 4 with the middle shell 2. By embedding the interlocking portion 42 into the second cavity 21, the partition 4 can be installed on the middle shell 2. The first connecting groove 43 is used to connect the first cavity 11 and the second cavity 21 to provide a passage for the FPC component 8 to pass through, thereby realizing the connection of related electronic devices; the second connecting groove 23 is used to connect the second cavity 21 and the second accommodating cavity 22 to provide a passage for the FPC component 8 to pass through. Specifically, the first connecting groove 43 allows the second fixing portion 84 to pass through to connect the third electrical connection portion 85, thereby realizing the electrical connection between the sound module 5 and the battery module 6. The second connecting groove 23 allows the first electrical connection portion 82 to pass through to connect the first fixing portion 81, thereby realizing the electrical connection between the mainboard 7 and the battery module 6.

[0036] After the FPC component 8 is bonded to the battery module 6, the first electrical connection portion 82 of the FPC component 8 is passed through the second connecting groove 23, so that after the mainboard 7 is subsequently installed in the second accommodating cavity 22, the mainboard 7 can be electrically connected to the battery module 6, and then the battery module 6 and the FPC component 8 are installed in the second cavity 21, and the FPC component 8 is adjusted to a predetermined position, that is, the second fixing portion 84 of the FPC component 8 is pre-adjusted to the position of the first connecting groove 43, and then the partition 4 is covered on the middle shell 2, so that the engaging portion 42 of the partition 4 can be embedded in the second cavity 21. After the partition 4 is fixed on the second cavity 21, the second fixing portion 84 of the FPC component 8 can pass through the first connecting groove 43, thereby realizing the electrical connection between the sound module 5 installed in the first cavity 11 and the battery module 6 installed in the second cavity 21, so as to realize the energy supply of the battery module 6 to the sound module 5.

[0037] It can be understood that by providing the first connecting groove 43 and the second connecting groove 23, the convenience of installing the FPC component 8 is improved, so as to realize the electrical connection between the battery module 6, the main board 7 and the sound module 5, thereby improving the stacking structure of the electronic components inside the wireless headset, and further optimizing the internal space layout of the wireless headset.

[0038] For further information, please refer to Figure 2 and Figure 3 In this embodiment, the first fixing portion 81 is bonded to a side of the battery module 6 close to the second accommodating cavity 22 , and the second electrical connection portion 83 is bonded between the battery module 6 and the partition 4 .

[0039] In a preferred embodiment, a positioning post (not shown) for positioning the third electrical connection part 85 is provided on the sound module 5 , and a positioning hole 86 matching with the positioning post is formed on the third electrical connection part 85 .

[0040] It is understandable that by bonding the first fixing portion 81 to the side of the battery module 6 close to the second accommodating cavity 22 and bonding the second electrical connection portion 83 between the battery module 6 and the partition 4, the convenience of installing the FPC component 8 can be improved on the basis of ensuring the stability of the installation of the FPC component 8. Similarly, by providing a positioning column and a positioning hole 86 on the sound module 5 and the third electrical connection portion 85, respectively, the installation efficiency of electrically connecting the FPC component 8 to the sound module 5 can be improved.

[0041] For further information, please refer to Figure 6 In one embodiment, a fixing groove 13 for mounting the second fixing portion 84 is formed in the front housing 1. A first microphone 10 is also disposed in the front housing 1, and the FPC member 8 further includes a fourth electrical connection portion 87 connected to the second fixing portion 84; the fourth electrical connection portion 87 is electrically connected to the first microphone 10.

[0042] The second fixing portion 84 is bonded to the fixing groove 13 so that the FPC component 8 can maintain a stable state. The first microphone 10 is used to collect external sounds located in the front shell 1 of the earphone to obtain and feedback related external sounds. The fourth electrical connection portion 87 is used to electrically connect the first microphone 10 to the mainboard 7 and the battery module 6 to realize the battery module 6 to supply energy to the first microphone 10 and the first microphone 10 to receive external sound feedback.

[0043] For further information, please refer to Figure 2 In one embodiment, the mainboard 7 is provided with a second microphone 20 and a third microphone (not shown), and the second microphone 20 and the third microphone are respectively provided at two ends of the mainboard 7. The mainboard 7 is also electrically connected with a touch module 71.

[0044] The second microphone 20 and the third microphone are used to receive audio signals outside the wireless headset, and the touch control module 71 is used to implement the touch control function of the wireless headset.

[0045] Specifically, a positioning member (not shown) for positioning the mainboard 7 and a fixing column (not shown) for fixing the mainboard 7 are formed on one surface of the middle shell 2 facing the second accommodating cavity 22, and the mainboard 7 can be installed in the second accommodating cavity 22 through the positioning member and the fixing column. An electrical connector 72 is provided between the touch module 71 and the mainboard 7, and the touch module 71 is electrically connected to the mainboard 7 through the electrical connector 72.

[0046] It can be understood that the middle shell 2 and the rear shell 3 are combined to form a second accommodating cavity 22, and the mainboard 7 is installed in the second accommodating cavity 22. During the installation of the mainboard 7, by forming a positioning piece on the side of the middle shell 2 facing the second accommodating cavity 22, the efficiency of the production line workers in installing the mainboard 7 can be improved. By providing a fixing column on the side of the middle shell 2 facing the second accommodating cavity 22, the stability of the connection between the mainboard 7 and the middle shell 2 can be ensured, and the mainboard 7 can be prevented from falling off during the use of the wireless headset.

[0047] In summary, the wireless headset provided by the present invention optimizes the stacking arrangement of electronic components inside the wireless headset through the arrangement of the partition 4 and the FPC component 8, thereby optimizing the layout of the internal space of the wireless headset, reducing the volume of the wireless headset, and improving the user experience.
