Description
Technical Field
[0001] The utility model relates to the technical field of Bluetooth headsets, and in particular to an in-ear TWS Bluetooth headset with an adaptive noise reduction function. Background Art
[0002] Bluetooth headsets are hands-free headsets that use Bluetooth technology, allowing users to get rid of the shackles of headphone wires and freely make calls, listen to music, etc. in various ways. With the rapid development of technology, wireless Bluetooth headsets are becoming more and more common, bringing great convenience to people's lives, work and study.
[0003] However, in a strong wind environment, the noise of Bluetooth headsets is too loud, making it difficult for users to clearly hear what is being played in the headset. Even when on a call, the other party can only hear the whistling sound of the wind, which greatly affects the user experience. Existing noise-cancelling Bluetooth headsets are not only expensive, but also affect the sound quality when reducing the noise.
[0004] Based on the above situation, the utility model proposes an in-ear TWS Bluetooth headset with adaptive noise reduction function. Utility Model Content
[0005] In order to overcome the shortcoming that the noise reduction of the existing Bluetooth headset affects the sound quality, the utility model provides an in-ear TWS Bluetooth headset with an adaptive noise reduction function.
[0006] The utility model provides an in-ear TWS bluetooth headset with an adaptive noise reduction function, comprising a main body, a connecting column, an arc long plate, a limiting rod, a connecting rod frame and a cylinder, the main body is fixedly connected to the connecting column, the main body is fixedly connected to the cylinder, the cylinder output end is fixedly connected to the connecting rod frame, the main body is fixedly connected to a pair of limiting rods, the connecting rod frame and the limiting rods are slidably connected, the connecting rod frame and the main body are slidably connected, the connecting rod frame is fixedly connected to the arc long plate, and the arc long plate is in contact with the main body.
[0007] Preferably, guide plates are also included, and the main body is fixedly connected with the guide plates which are longitudinally distributed up and down.
[0008] Preferably, blocking sheets are also included, and the main body is fixedly connected with a pair of blocking sheets for blocking external dust and debris.
[0009] Preferably, it also includes a limiting column, a reset spring, a large arc plate and a double round head plate. The main body is slidably connected to the limiting column. A reset spring is fixed between the limiting column and the main body. The limiting column is fixedly connected to the large arc plate, and the large arc plate is fixedly connected to the double round head plate.
[0010] Preferably, a pair of square holes are opened on the front side of the main body for allowing the connecting rod frame to slide left and right.
[0011] Preferably, the blocking sheet is made of sponge material to absorb noise.
[0012] The beneficial effects of the utility model are: 1. The utility model uses components such as a cylinder and an arc long plate to enable the earphone to guide or block airflow in strong wind conditions, preventing airflow from entering the Bluetooth earphone to reduce wind noise and increase user experience, and does not block the earphone air inlet in a wind-free environment to avoid a reduction in earphone sound quality.
[0013] 2. The utility model continuously squeezes the earphone body through the limit column, the return spring and the double round head plate, so that the earphone body is always fixed in the ear, preventing the earphone from slipping due to the user's movement, so as to increase the stability of the Bluetooth earphone after it is fixed.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0020] An in-ear TWS Bluetooth headset with adaptive noise reduction function, such as Figure 1-Figure 3As shown, it includes a main body 1, a connecting column 2, an arc long plate 4, a limiting rod 5, a connecting rod frame 6 and a cylinder 7. The connecting column 2 is fixedly connected to the right side of the main body 1, the cylinder 7 is fixedly connected to the right side inside the main body 1, the connecting rod frame 6 is fixedly connected to the output end of the cylinder 7, and a pair of limiting rods 5 are fixedly connected to the left side inside the main body 1. The connecting rod frame 6 and the limiting rods 5 are slidably connected. The limiting rods 5 are used to limit the connecting rod frame 6 so that the connecting rod frame 6 can only slide but not rotate. The connecting rod frame 6 and the main body 1 are slidably connected. The arc long plate 4 is fixedly connected to the front side of the connecting rod frame 6. The arc long plate 4 is used to guide the airflow. The arc long plate 4 is in contact with the main body 1, and the cylinder 7 is used to drive the connecting rod frame 6 and the arc long plate 4 to move left and right.
[0021] like Figure 1 As shown, a guide plate 3 is also included. The front side of the main body 1 is fixedly connected with the guide plate 3 which is longitudinally distributed up and down. The guide plate 3 is used to guide the airflow.
[0022] like Figure 4 As shown, it also includes blocking sheets 8. A pair of blocking sheets 8 are fixedly connected to the front side of the main body 1. The blocking sheets 8 are made of sponge material and are used to block external dust and debris.
[0023] When the user wears the earphones under normal circumstances, the arc long plate 4 does not contact the main body 1, and the arc long plate 4 does not block the earphone air inlet. At this time, the sponge material blocking sheet 8 at the earphone air inlet blocks external dust and debris and absorbs noise. When the user wears the earphones under strong wind conditions, the guide plate 3 can be used to guide the airflow through the earphones to reduce wind noise. The cylinder 7 can also be started according to the wind direction and wind speed to drive the connecting rod frame 6 and the arc long plate 4 to move to the right to a suitable position to block and guide the strong wind, thereby reducing wind noise. When the wind direction is chaotic and uncertain, the user can start the cylinder 7 to drive the connecting rod frame 6 and the arc long plate 4 to move to the right until the arc long plate 4 contacts the main body 1. At this time, the arc long plate 4 completely blocks the earphone air inlet to prevent strong wind from blowing in to reduce wind noise, but the sound quality of the earphone will be reduced at this time. Therefore, when the weather is normal, the cylinder 7 needs to be started to drive the connecting rod frame 6 and the arc long plate 4 to move to the left to return to their original position.
[0024] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a limiting column 9, a return spring 10, an arc plate 11 and a double round head plate 12. The left side of the main body 1 is slidably connected to the limiting column 9, and a return spring 10 is fixedly connected between the limiting column 9 and the main body 1. One end of the arc plate 11 is fixedly connected to the top of the limiting column 9, and the other end of the arc plate 11 is fixedly connected to the double round head plate 12. The double round head plate 12 can enable the Bluetooth headset to be hung on the ear.
[0025] When the user wears a Bluetooth headset during exercise, the Bluetooth headset may slip out of the ear and cause damage to the headset. Therefore, after the user fixes the headset body 1 in the ear, the user can also push the double round head plate 12 to move to the right and fix it on the ear. The limiting column 9 also moves to the right, and the return spring 10 is compressed. The headset body 1 will be stably fixed in the ear under the pressure of the return spring 10. When the user takes off the Bluetooth headset, the limiting column 9, the double round head plate 12 and other components move to the left and reset under the action of the return spring 10.
[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
