Description

Technical Field

[0001] The present invention relates to the technical field of wireless earphones, in particular to a wireless earphone based on a switching structure and capable of changing direction according to the use of an ear canal. Background Art

[0002] Wireless headphones are headphones that transmit audio signals through radio waves. The middle wire is replaced by radio waves and connected from the audio outlet to the transmitter. The transmitter then sends the signal to the headphones at the receiving end via radio waves. The receiving end is equivalent to a radio. There are mainly Bluetooth connections and other wireless connection methods, such as infrared, radio frequency, etc., but Bluetooth connection is currently the most common and mainstream method.

[0003] Wireless headphones are earphones that are worn on the ears to receive sound. Earhook wireless headphones are typically only fixed to one ear during use, and cannot be worn on both ears simultaneously. Therefore, when using them, the earphone corresponding to the left or right ear must be removed before being put on, reducing the adaptability of earhook headphones.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-11The present invention provides a technical solution: a wireless headset that changes direction according to the ear canal in use based on a switching structure, comprising an earphone body 1, a middle shell 3 fixedly connected to the surface of the earphone body 1, a battery 4 installed in the inner cavity of the middle shell 3, and an ear hook mechanism 2 provided on the surface of the middle shell 3;

[0038] The ear hanging mechanism 2 includes a rotating unit 21, which is arranged in the inner cavity of the middle shell 3;

[0039] The ear hanging mechanism 2 further includes a fixing unit 22 . The fixing unit 22 is disposed on the surface of the rotating unit 21 . The rotating unit 21 and the fixing unit 22 cooperate with each other for use.

[0040] As a further limitation of the present invention, the rotating unit 21 includes a support plate 2105, one side of the support plate 2105 is fixedly connected to the inner wall of the middle shell 3, a rotating shell 2104 is provided through the bottom of the middle shell 3, the rotating shell 2104 is connected to the middle shell 3 by a bearing, the bottom end of the rotating shell 2104 is provided with a connecting battery 2103, one side of the connecting battery 2103 is provided with an elastic ear hook 2101, the inner cavity of the elastic ear hook 2101 is provided with a rechargeable battery and is electrically connected to the connecting battery 2103, the top of the connecting battery 2103 is fixedly connected to the connecting copper sheet 2112, and the rotating shell 21 04 is movably provided with a rotating column 2106 on the top, and a positioning ball 2107 is movably embedded on the top of the rotating column 2106.

By setting the positioning grooves 2113, the positioning ball 2107 can be positioned. After the rotating shell 2104 rotates, the rotating shell 2104 will not rotate by itself, thereby ensuring the stability of the elastic ear hook 2101 after adjustment, so that the elastic ear hook 2101 can be stably worn on the ear, allowing it to adapt to being worn on the left or right ear.

[0041] One end of the rotating column 2106 is fixedly connected to a positioning spring 2108, and the inner cavity of the rotating shell 2104 is provided with a first limiting groove 2111 used to cooperate with the rotating column 2106. There are two first limiting grooves 2111. By setting the first limiting groove 2111, the rotating column 2106 can be limited, so that it can follow the rotation when the rotating shell 2104 rotates, ensuring that the positioning ball 2107 can enter the positioning groove 2113 to position the rotating shell 2104, so that the elastic ear hook 2101 will not rotate, allowing it to be better worn.

[0042] A circular shell 2102 is fixedly connected to one side of the battery 2103, and the inner cavity of the circular shell 2102 is movably connected to a rotating plate 2110 through a bearing. A connecting column 2109 slides through the surface of the rotating plate 2110, and one end of the elastic ear hook 2101 is fixedly connected to the surface of the connecting column 2109. A tightening spring 2114 is fixedly connected to the surface of the rotating plate 2110.

By setting the rotating plate 2110, the connecting column 2109 can be rotated, so that the elastic ear hook 2101 can be rotated and adjusted to suit the left ear or the right ear, thereby improving adaptability.

[0043] The fixing unit 22 includes a movable plate 2204, the top of the movable plate 2204 is fixedly connected to one end of the positioning spring 2108, an L-shaped clamping rod 2202 is provided on one side of the movable plate 2204, the number of the L-shaped clamping rods 2202 is two, the surface of the movable plate 2204 is provided with a mounting hole 2206, the number of the mounting holes 2206 is four, the inner cavity of the mounting hole 2206 is fixedly connected to a tension spring 2205, one end of the tension spring 2205 is fixedly connected to the surface of the L-shaped clamping rod 2202, one end of the L-shaped clamping rod 2202 passes through the outer side of the rotating shell 2104, and the L-shaped clamping rod 2202 is fixedly connected to the outer side of the rotating shell 2104. 02's surface is fixedly connected with two fixed blocks 2203, the surface of the rotating shell 2104 is provided with a movable hole 2208 used to cooperate with the L-shaped clamping rod 2202, the surface of the rotating shell 2104 is fixedly connected with an L-shaped connecting plate 2201, the number of L-shaped connecting plates 2201 is two, and the surface of the connecting battery 2103 is provided with a second fixing hole 2207 used to cooperate with the fixed block 2203. By setting the L-shaped connecting plate 2201, the connection battery 2103 can be limited to make the fixation more stable, while also ensuring the stability of the fixation of the elastic ear hook 2101, so that the wearing effect is better.

[0044] By setting up the coordinated use of the rotating unit 21 and the fixed unit 22, the purpose of changing the wearing direction can be achieved, so that when the ear-hook earphones are worn, there is no need to deliberately take out the earphones corresponding to the left ear or the right ear to wear them. The user can flexibly choose which earphone to wear according to his or her needs and habits without worrying about the problem of distinguishing between the left and right ears of the earphones, which improves the convenience of use and effectively improves the adaptability of the ear-hook earphones.

[0045] The specific implementation of this embodiment is as follows: when the user needs to change the earphone body 1 to wear the earphone body 1, the rotating shell 2104 can be rotated to allow the elastic ear hook 2101 to rotate to the other side of the middle shell 3. While rotating, the rotating column 2106 can follow the rotating shell 2104 to rotate through the limitation of the first limiting groove 2111, so that the rotating column 2106 drives the positioning ball 2107 to disengage from the positioning groove 2113, and at the same time, the rotating column 2106 moves downward to squeeze the positioning spring 2108. After the elastic ear hook 2101 rotates to one side of the middle shell 3, the positioning ball 2107 enters the positioning groove 2113 again, and the positioning spring 2108 resets and pushes the rotating column 2106 to move upward, thereby applying pressure to the positioning ball 2107, so that the positioning ball 2107 can be stably in the positioning groove 2113, thereby The elastic ear hook 2101 is positioned, and then the elastic ear hook 2101 is pulled to allow the connecting post 2109 to squeeze the tightening spring 2114 to shrink it, so that the connecting post 2109 can move out of the first fixing hole 2115, and then the elastic ear hook 2101 is rotated, and the rotating plate 2110 is rotated under the action of the connecting post 2109, so that the position of the elastic ear hook 2101 is adjusted again, so that it can be adjusted to a position suitable for the other ear, so that it can be worn, so that the earphone body 1 can be adapted to be worn on both the left ear and the right ear at the same time, thereby improving the adaptability of wearing. When the elastic ear hook 2101 needs to be removed, the tension spring 2205 is extended by pulling the L-shaped clamping rod 2202, so that the fixing block 2203 is moved out of the second fixing hole 2207, thereby not fixing the connected battery 2103, and allowing the elastic ear hook 2101 to be removed.

[0046] Example 2: Please refer to Figures 1-11 The present invention provides a technical solution: a wireless headset based on a switching structure that changes direction according to the use of the ear canal. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0048] The conversion mechanism 5 includes a square shell 503, one side of the square shell 503 is fixedly connected to the inner cavity of the earphone body 1, there are two square shells 503, the inner cavity of the square shell 503 is fixedly connected with a connecting spring 508, one end of the connecting spring 508 is fixedly connected with a fixing plate 507, the surface of the earphone body 1 is provided with an in-ear earplug 502, the surface of the in-ear earplug 502 is movably provided with a cover shell 501, the surface of the cover shell 501 is fixedly connected with a fixing rod 506, there are two fixing rods 506, by setting the fixing plate 507, the fixing rod 506 can be limited, so that the cover shell 501 can be fixed on the earphone body 1, thereby covering the in-ear earplug 502, making it become a semi-in-ear style for wearing, allowing it to switch between in-ear and semi-in-ear styles.

[0049] A guide plate 505 is fixedly connected to the surface of the shell 501, and there are two guide plates 505. The inner cavity of the earphone body 1 is provided with a guide groove 504 used to cooperate with the guide plate 505, and the inner cavity of the square shell 503 is provided with a second limiting groove 509 used to cooperate with the fixing plate 507. There are two second limiting grooves 509. By setting the guide groove 504, the guide plate 505 can be guided so that the shell 501 can be stably docked with the earphone body 1, so that it can better fix the shell 501 and ensure the fixing effect. By setting the second limiting groove 509, the fixing plate 507 can be limited so that the fixing plate 507 can move more stably in the square shell 503, so that it can better limit the fixing rod 506 and ensure the fixation stability of the shell 501.

[0050] The inner cavity of the rotating shell 2104 is fixedly connected to a connector 8 , the surface of the connector 8 is fixedly connected to a wire 7 , and one end of the wire 7 is electrically connected to the surface of the battery 4 .

By setting the connecting copper sheet 2112, it can be connected to the connector 8. After the elastic ear hook 2101 is installed on the middle shell 3, the connected battery 2103 can be connected to deliver electricity, thereby powering the battery 4, allowing the elastic ear hook 2101 to be used as a backup power supply, thereby improving the battery life of the earphone body 1.

[0053] The specific implementation of this embodiment is as follows: when the in-ear wearing is required, the cover 501 is pulled upward, so that the fixing rod 506 can move upward, thereby squeezing the fixing plate 507, so that the fixing plate 507 squeezes the connecting spring 508, so that the connecting spring 508 can shrink, and the fixing rod 506 can move above the fixing plate 507, so that the cover 501 can be removed, so that the in-ear earplug 502 can be exposed, thereby changing to the in-ear wearing mode.
