[0047] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0048] like Figures 1 to 10 As shown, an embodiment of the present application provides a wireless Bluetooth headset 100, including a headset body 10, a first soft support portion 20 and a microphone 30, wherein the headset body 10 is provided with a sound outlet 13, and the headset body 10 is provided with a speaker and a circuit board 14; the first soft support portion 20 is connected to the headset body 10, and the first soft support portion 20 is provided with a wearing portion 21, and the wearing portion 21 is in a strip shape or a pointed shape, specifically, as shown in FIG. Figures 1 to 4 As shown, the wearing portion 21 is in a strip shape. Figure 5 As shown, the wearing portion 21 is in a pointed shape, and its pointed shape is similar to a triangle, and the end away from the earphone body is more pointed than the end close to the earphone body. When the wireless Bluetooth headset 100 is worn, Fig. 9 and Fig.10 As shown, the wearing portion 21 is clamped between the tragus 201 and the antitragus 202 of the human ear 200, the earphone body 10 is in contact with the concha cavity 205 of the human ear 200, and the first soft supporting portion 20 is provided with an installation cavity and a sound receiving channel, and the sound receiving channel is located on the side of the wearing portion 21 away from the human ear 200, so as to facilitate the sound receiving from the outside world; the microphone 30 is arranged in the installation cavity, and is electrically connected to the circuit main board 14 through the flexible circuit 16, and the sound receiving hole of the microphone 30 is connected to the sound receiving channel.

[0049] The wireless Bluetooth headset 100 provided in the embodiment of the present application is provided with a first soft supporting portion 20 installed on one side of the headset body 10. The first soft supporting portion 20 is soft so that it has a certain deformation amount. When worn, the headset body 10 abuts against the concha cavity 205 of the human ear 200, so that the inner ear cavity 206 at the bottom of the concha cavity 205 provides an upward lifting force to the headset body 10. The wearing portion 21 is clamped between the tragus and the antitragus of the human ear, and can adapt to the ears of different wearers by squeezing and deforming, so that the product is located in the human ear, occupies less space, and is more comfortable to wear for a long time, thereby improving the comfort of the product and avoiding the problem of poor comfort caused by the existing hard earphone shell squeezing the human ear 200. In addition, the microphone 30 is installed in the first soft supporting portion 20 to realize voice calls and reduce the overall volume of the product.

[0050] Specifically, the earphone body 10 is made of a hard material, and the earphone body 10 is in a circular shape. When worn, the earphone body 10 abuts against the inside of the concha cavity 205 of the human ear. The first soft supporting part 20 is made of a relatively soft material compared to the hard material, such as a thermoplastic polyurethane elastomer, that is, the first soft supporting part 20 is a soft body that can be squeezed and deformed without causing discomfort to the wearer's ears. The wearing part 21 can be elastically deformed with the wearer's ears, so that it is convenient to clamp it between the tragus 201 and the antitragus 202. In this way, the wearer will not feel uncomfortable even if it is worn for a long time, and can even be worn while sleeping, without causing the ears to be squeezed and feel pain, thereby improving the comfort of the product.

[0051] It should be noted that the circuit main board 14 of the earphone body 10 is the same as the circuit connection principle of the existing wireless Bluetooth earphone. Specifically, the microphone 30 and the flexible circuit board 16 are installed in the installation cavity, and the flexible circuit board 16 is electrically connected to the circuit main board 14 of the earphone body 10 to realize the call microphone 30 function. Specifically, the circuit connection is the same as the circuit principle of the wireless Bluetooth earphone. What is changed in this application is the installation position of the microphone 30 and the installation of the first soft support part 20. The connection circuit principle of the wireless Bluetooth earphone 100 is the same as the principle of the common Bluetooth wireless earphone. Therefore, it will not be described one by one.

[0052] In some embodiments of the present application, optionally, Figure 7As shown, the maximum radial length h of the earphone body 10 is less than 17 mm. It is ensured that the earphone body 10 is just against the concha cavity 205 of the human ear 200, so that the inner ear cavity 206 at the bottom of the concha cavity 205 provides an upward lifting force to the earphone body 10, thereby preventing the earphone body 10 from falling from the human ear 200. It should be noted that the maximum radial direction of the earphone body 10 is the maximum distance between two points on the shape of the earphone body. When the earphone body 10 is circular, the maximum radial length h is the diameter. When the earphone body 10 is elliptical, the maximum radial length h is the major axis diameter. When the earphone body 10 is an irregular shape, the maximum radial length h is the maximum distance between two points on the circumference of the irregular shape.

[0053] In some embodiments of the present application, optionally, Figure 3 As shown, the distance d between the end face of the first soft support part 20 away from the earphone body 10 and the end face of the farthest end of the earphone body 10 is less than 24 mm. In this way, when wearing, it can ensure that the wearing part 21 on the first soft support part 20 can be completely located between the tragus 201 and the antitragus 202, preventing the product from falling off from the human ear 200.

[0054] In some embodiments of the present application, optionally, Figures 7 to 10 As shown, the wireless Bluetooth headset 100 also includes a second soft support portion 40, which is connected to the headset body 10, and the second soft support portion 40 and the first soft support portion 20 are respectively located on both sides of the headset body 10, and the second soft support portion 40 abuts against the antihelix 203 of the human ear 200.

[0055] In this embodiment, a second soft support portion 40 is further provided on the earphone body 10. The second soft support portion 40 is also a soft rubber shell. When the wearer wears the wireless Bluetooth earphone 100, the second soft support portion 40 abuts against the anti-auricle 203, playing a supporting and stabilizing role, thereby preventing the wireless Bluetooth earphone 100 from falling. Figure 8 As shown, the second soft supporting part 40 is an ivory-shaped soft rubber shell, and the ivory-shaped soft rubber shell is extended along the circumference of the earphone body 10, that is, the structural shape of the second soft supporting part 40 matches the antihelix 203, which is convenient for use with the ear of the human ear 200, and will not reduce the comfort of the wearer when wearing for a long time. Specifically, when worn, the sound receiving channel opening of the first soft supporting part 20 and the sound receiving channel opening of the second soft supporting part 40 are aligned with the wearer's mouth, which helps the microphone in the first soft supporting part 20 and the microphone in the second soft supporting part 40 to collect the sound emitted by the wearer, and can ensure a good noise reduction function, thereby improving the wearer's usage experience.

[0056] In the above-mentioned embodiment of the present application, optionally, a accommodating cavity and a sound receiving channel are provided in the second soft supporting portion 40; the wireless Bluetooth headset 100 also includes a noise reduction microphone, which is provided in the accommodating cavity and electrically connected to the circuit main board 14, and the sound receiving hole of the noise reduction microphone is connected to the sound receiving channel.

[0057] In this embodiment, a accommodating cavity and a sound receiving channel are provided in the second soft supporting portion 40, and at the same time, a through hole communicating with the sound receiving channel is provided on the second soft supporting portion 40, so that the noise reduction microphone is installed in the accommodating cavity, and the noise reduction microphone is also electrically connected to the flexible circuit board, and the flexible circuit board is electrically connected to the main circuit board of the earphone body 10. The specific circuit connection and control principle are the same as the circuit connection and control principle of the existing noise reduction microphone and wireless Bluetooth headset. In this way, the wireless Bluetooth headset 100 of the present application has two microphones 30, one for calls and the other for noise reduction. After the wearer wears it, the microphone 30 for calls is located in the downward position of the earphone body 10, and the noise reduction microphone is located in the upward position. Optionally, a certain preset distance is ensured between the noise reduction microphone and the microphone 30 for calls, so that it can be ensured that the collected human voice has a volume difference. Optionally, the distance between the microphone 30 and the noise reduction microphone is 15mm to 18mm.

[0058] In some embodiments of the present application, optionally, Figure 4 As shown, the earphone body 10 includes a top shell 11 and a bottom shell 12 , the top shell 11 and the bottom shell 12 form a cavity, and the speaker and the circuit main board 14 are arranged in the cavity.

[0059] In this embodiment, the earphone body 10 can be composed of a top shell 11 and a bottom shell 12. The bottom shell 12 is the side facing the concha cavity 205 when worn, and the top shell 11 is the side facing the outside when worn. The top shell 11 and the bottom shell 12 form a cavity, and the electronic components 14 of the earphone are installed in the cavity. Optionally, a notch 15 is provided on the top shell 11 and the bottom shell 12, and a limiting portion 22 is provided on the first soft support portion 20. The limiting portion 22 is arranged in the cavity. The first soft support portion 20 extends out of the notch 15 and is clamped at the notch 15 through the limiting portion 22 to prevent the entire first soft support portion 20 from detaching from the notch 15. At the same time, the first soft support portion 20 is also installed on the earphone body 10 through the limiting portion 22.

[0060] In some embodiments of the present application, optionally, Figure 6 As shown, a sound outlet 13 is provided on the earphone body 10 , and an angle θ is formed between the projection of the sound outlet 13 on the bottom shell 12 and the first soft support portion 20 , and the angle θ is 25 degrees to 35 degrees.

[0061] In this embodiment, the sound outlet 13 of the earphone body 10 and the projection of the first soft support part 20 on the surface where the earphone body 10 is located form a certain angle, and the angle range of the angle is 25 degrees to 35 degrees, that is, the projection of the microphone 30 and the sound outlet 13 on the earphone body 10 forms this angle, which is in consideration of the structural characteristics of the human ear. When wearing, the sound outlet 13 on the earphone body needs to enter the ear canal of the human ear, and the wearing part 21 of the first soft support part needs to be clamped between the tragus and the antitragus of the human ear. Reasonable angle setting makes it easy for the wearer to wear comfortably.

[0062] In some embodiments of the present application, optionally, Figure 4 As shown, the distance a from the side of the wearing part 21 close to the sound outlet 13 to the bottom surface of the bottom shell 12 is 6mm to 9mm, and the maximum radial length b of the wearing part 21 along the direction perpendicular to the bottom shell 12 is 3mm to 6mm. Such a design can ensure that the wearing part 21 and the earphone body 10 are in the human ear 200, making it difficult for them to completely enter the human ear 200. At the same time, it can also ensure that the wearing part 21 is located between the tragus 201 and the antitragus 202, making it more comfortable and reliable when worn.

[0063] In some embodiments of the present application, optionally, Figures 1 to 4 As shown, the first soft support portion 20 is disposed on the top shell 11; or

[0064] The first soft supporting portion 20 is disposed on the bottom shell 12 .

[0065] In this embodiment, the first soft support portion 20 can be installed on the bottom shell 12 or on the top shell 11 , and can be installed according to different structural shapes.

[0066] In the above embodiment of the present application, optionally, the first soft support part 20 is integrally formed with the top shell 11, wherein the top shell 11 is made of a rigid plastic material by injection molding, and the first soft support part 20 is made of a flexible plastic material by injection molding. Specifically, the soft rubber material, that is, the first soft support part 20 and the top shell 11 can be integrally formed by two-color injection molding, and the top shell 11 can be made of hard plastic.

[0067] It should be noted that the second soft support part 40 can also be installed on the top shell 11, or the second soft support part 40 can be installed on the bottom shell 12, or it can be installed at a position between the top shell 11 and the bottom shell 12, or the second soft support part 40 can be integrally molded with the top shell 11 like the first soft support part 20, that is, the manufacturing and installation method is the same as the first soft support part 20, and it will not be repeated here.

[0068] In some embodiments of the present application, optionally, the first soft support portion 20 is a soft plastic shell made of a flexible material integrally molded.

[0069] In this embodiment, the earphone body 10 is made of a hard material, and the first soft supporting portion 20 is made of a relatively soft material, such as a thermoplastic polyurethane elastomer. That is, the first soft supporting portion 20 is a soft body that can be squeezed and deformed without causing discomfort to the wearer's ears, and can elastically deform along with the wearer's ears. In this way, the wearer will not feel uncomfortable even when wearing it for a long time, and can even wear it while sleeping without causing the ears to be squeezed and feel pain, thereby improving the comfort of the product.

[0070] Specifically, if Figures 1 to 10 As shown, the wireless Bluetooth headset 100 provided in this embodiment works as follows:

[0071] By setting a soft soft-gel shell (first soft supporting part 20) on one side of the earphone body 10, another soft soft-gel shell (second soft supporting part 40) can also be set on the other side of the earphone body 10 at the same time. At the same time, a microphone 30 with a call function is set in the first soft supporting part 20, and a noise reduction microphone 30 is set in the second soft supporting part 40. When worn on the human ear 200, the earphone body 10 abuts against the concha cavity 205 of the human ear 200, so that the inner ear cavity 206 at the bottom of the concha cavity 205 provides an upward lifting force to the earphone body 10. The first soft support portion 20 is supported and fixed between the tragus 201 and the antitragus 202, and the second soft support portion 40 is supported and fixed at the antihelix 203, that is, the inner side of the helix 204. The soft rubber shell can be squeezed and deformed without causing discomfort to the wearer's ears, and can elastically deform along with the wearer's ears. In this way, the wearer will not feel uncomfortable when wearing it for a long time, and can even wear it during sleep without causing the ears to be squeezed and feel pain, thereby improving the comfort of the product. The soft rubber shell has the function of installing the microphone 30 and can also play a stabilizing role when worn.

[0072] To sum up, the wireless Bluetooth headset provided by the present embodiment has at least the following beneficial technical effects: the wireless Bluetooth headset provided by the embodiment of the present application, by installing a first soft support part on one side of the headset body, the first soft support part is soft so that it has a certain deformation amount, and at the same time, the wearing part on the first soft support part can adapt to the ears of different wearers through extrusion and deformation, making it more comfortable to wear for a long time, thereby improving the comfort of the product and avoiding the problem of poor comfort caused by the existing hard earphone shell squeezing the human ear. In addition, the microphone is installed in the first soft support part to realize voice calls and reduce the overall volume of the product.

[0073] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
