[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] In the description of the embodiments of the present application, it should be noted that, unless otherwise specified or limited, the term "axial direction" refers to the axial direction of the rotating rod. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood in specific circumstances.

[0032] In the description of the embodiments of the present application, it should be noted that the terms "center," "bottom," "inner," and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present application and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0034] In related technologies, buttons on the sound unit of headphones are generally used to turn the headphones on and off or adjust the volume through plastic physical buttons or touch buttons. To achieve both power on and off and volume adjustment, plastic physical buttons require three plastic physical buttons on the sound unit, which takes up a lot of space and is very destructive to the appearance. Touch buttons generally only have single-point touch and can only achieve single functions such as play, pause, and answer calls. They generally cannot adjust the volume, resulting in a poor user experience.

[0035] Based on the above situation, the embodiment of the present application provides an earphone 10, please refer to Figures 1 to 6 The earphone 10 includes a sound-emitting unit 11, which includes a shell 111, an encoder 112 and a knob 113. A accommodating cavity 111a is formed in the shell 111. The encoder 112 is arranged in the accommodating cavity 111a. The encoder 112 includes a code disk 1121. Part of the structure of the knob 113 protrudes from the outer surface of the shell 111. The knob 113 is connected to the code disk 1121 and can drive the code disk 1121 to rotate. The encoder 112 is used to identify the rotation state of the knob 113 to realize the switch control and volume adjustment of the earphone 10.

[0036] It should be noted that the earphone 10 in the embodiment of the present application can be any type of earphone, such as an earhook or ear clip earphone 10.

[0037] Exemplarily, the earphone 10 in the embodiment of the present application may be a fully open wearable earphone.

[0038] Fully open wearable headphones, also known as OWS (Open Wearable Stereo) headphones, use air conduction. The main design concept is "fully open" and "not in the ear", ensuring comfort for long-term wearing.

[0039] It should be noted that the sound-emitting unit 11 is a part of the earphone 10 . The sound-emitting unit 11 is located in front of the ear when the earphone is worn, and emits sound to the ear and transmits the sound to the user.

[0040] The sound-emitting unit 11 may be in the shape of a long strip, an oblate circle or other shapes.

[0041] Exemplarily, the earphone 10 further includes a connecting unit 12 connected to the sound-emitting unit 11 . The connecting unit 12 matches the contour of the human ear, thereby fixing the sound-emitting unit 11 on the ear and enabling the earphone 10 to be worn.

[0042] The housing 111 of the sound unit 11 has a receiving cavity 111 a for receiving other components. For example, the receiving cavity 111 a can be used to receive a circuit board 115 , a sound-emitting part, or a magnetic component.

[0043] It should be noted that encoder 112 is a sensor that uses optical, magnetic, or mechanical contact to sense position and converts the position into an electronic signal for output as feedback signal for position control. Encoders 112 can be divided into linear encoders and rotary encoders based on their motion.

[0044] The embodiment of the present application uses a rotary encoder, which can convert the rotational position or rotation amount into an analog (such as an analog orthogonal signal) or digital (such as a USB, a 32-bit parallel signal or a digital orthogonal signal, etc.) electronic signal. The rotary encoder is usually installed on the rotating object.

[0045] The encoder 112 is arranged in the accommodating cavity 111a, so as to protect the encoder 112. At the same time, the encoder 112 can be arranged closer to the circuit board 115, shortening the electrical connection path between the encoder 112 and the circuit board 115, making the electrical circuit inside the earphone 10 simpler.

[0046] It should be noted that the encoder 112 in the embodiment of the present application has a switch, so that the knob 113 can not only adjust the volume through the encoder 112, but also control the opening and closing of the earphone 10.

[0047] It should be noted that the encoder 112 generally includes a code disk 1121 and a housing. The code disk 1121 of the encoder 112 can rotate relative to the housing of the encoder 112, and the housing of the encoder 112 is fixedly connected to the shell.

[0048] Knob 113 is connected to the rotatable portion of encoder 112, namely, code disk 1121, and knob 113 can drive code disk 1121 to rotate, which means that there is no relative rotation between knob 113 and code disk 1121. When the user rotates knob 113, knob 113 can drive code disk 1121 to rotate synchronously. Encoder 112 converts the detected rotational position or rotation amount of code disk 1121 into an electronic signal, thereby controlling the volume and powering of earphones 10.

[0049] Part of the structure of the knob 113 protrudes from the outer surface of the shell 111, which helps the user find and turn the knob 113 more quickly. At the same time, another part of the knob 113 is hidden in the shell 111, which limits the knob 113 and improves the appearance of the sound unit 11.

[0050] For example, the knob 113 is made of metal, which can serve as a decoration for the earphone 10 and also increase the tactile feel.

[0051] The earphone 10 provided in the embodiment of the present application has an encoder 112 with a switch disposed within the housing 111a of the housing 111 of the sound unit 11. This allows the encoder 112 to be positioned closer to the circuit board 115, shortening the electrical connection path between the encoder 112 and the circuit board 115 and simplifying the electrical circuitry within the earphone 10. Furthermore, a knob 113 is connected to a code disk 1121 of the encoder 112. When a user rotates the knob 113, the knob 113 drives the code disk 1121 to rotate synchronously. The encoder 112 converts the detected rotational position or amount of rotation of the code disk 1121 into an electronic signal, thereby controlling the volume and powering the earphone 10. By disposing a single knob 113 on the sound unit 11 of the earphone 10, both the power on and the volume of the earphone 10 can be adjusted, reducing space usage, facilitating the miniaturization of the earphone 10, enhancing the aesthetics of the earphone 10, and improving the user experience.

[0052] In some embodiments, the knob 113 has at least a first rotation state and a second rotation state. In the first rotation state, the earphone 10 is in an open state, and in the second rotation state, the earphone 10 is in a closed state. The knob 113 can rotate back and forth circumferentially between the first rotation state and the second rotation state to realize the on / off control of the earphone 10.

[0053] It should be noted that, with the rotation center axis of the knob 113 as a reference, the rotation direction of the knob 113 is the circumferential direction, and the direction of the rotation center axis of the knob 113 is the axial direction.

[0054] It should be noted that the first rotation state and the second rotation state are two different positions of the knob 113 in the circumferential direction, and there is a certain angle between the two positions, that is, the earphone 10 is turned on and off by rotating to different positions, which can improve the situation where the earphone 10 is accidentally turned off or turned on due to accidental touch, thereby improving the user experience during use.

[0055] In some embodiments, the knob 113 can rotate to a first position, a second position, and a third position sequentially arranged along the same circumference. In the first position, the volume of the earphone 10 is at a first limit. In the second position, the volume of the earphone 10 is at a second limit. The knob 113 can be rotated from the second position away from the first position to a third position to turn off the earphone 10. Furthermore, the knob 113 can be rotated from the third position toward the first position to turn on the earphone 10.

[0056] It should be noted that the same circumference refers to a circle extending outward from the center of the knob 113 , and the radius of the circumference does not exceed the outer diameter of the knob 113 .

[0057] It should be noted that the total rotation stroke of the knob 113, that is, the stroke of the knob 113 from the first position to the third position, can be less than one circle, equal to one circle, greater than one circle, etc., and is not limited here.

[0058] That is, the second position may be the position where the knob 113 has just completed one circle and returned to the first position.

[0059] The volume is in a first limit state, that is, the state where the volume of the earphone 10 is the maximum.

[0060] The volume is in the second limit state, that is, the state where the volume of the earphone 10 is the minimum.

[0061] The third position is the state where the earphone 10 is turned off.

[0062] The second position is the state where the earphone 10 is turned on and the volume is at the lowest.

[0063] For example, there is friction resistance when the knob 113 switches between the second position and the third position, thereby improving the situation where the power on / off operation is easily misoperated due to accidental touching of the knob 113, and improving the user experience.

[0064] For some examples, see Figure 5 and Figure 6The knob 113 includes a screw cap 1131 and a screw rod 1132 connected to each other. At least a portion of the screw cap 1131 protrudes from the outer surface of the housing 111. The housing 111 is provided with a mounting opening 111b. The screw rod 1132 is inserted into the mounting opening 111b and connected to the code disk 1121.

[0065] Exemplarily, the screw cap 1131 is disc-shaped.

[0066] For example, the rotation centers of the rotating rod 1132 and the rotating cap 1131 coincide, that is, the rotating cap 1131 can rotate relative to the central axis of the rotating rod 1132. The rotating rod 1132 and the rotating cap 1131 can be an integrated structure, that is, the rotating rod 1132 and the rotating cap 1131 are integrally manufactured, which reduces the manufacturing difficulty of the knob 113 and reduces the installation process.

[0067] Exemplarily, a portion of the rotary cap 1131 protruding from the outer surface of the housing 111 is formed with an anti-slip groove, which can increase the friction resistance between the user and the rotary cap 1131 , thereby facilitating the user to turn the knob 113 .

[0068] It should be noted that the mounting opening 111b extends through the housing 111 and communicates with the accommodating chamber 111a. The rotating rod 1132 extends from the outside of the housing 111 through the mounting opening 111b and into the accommodating chamber 111a. Thus, the knob 113 is connected to the code disk 1121 of the encoder 112 via the rotating rod 1132, enabling the knob 113 to drive the synchronous rotation of the code disk 1121.

[0069] For some examples, see Figure 5 The outer peripheral surface of the rotating rod 1132 is spaced apart from the inner wall surface of the installation opening 111b.

[0070] That is to say, there is a gap between the rotating rod 1132 passing through the mounting port 111b and the mounting port 111b, and the outer peripheral surface of the rotating rod 1132 does not contact the inner wall surface of the mounting port 111b. When the rotating rod 1132 rotates, the rotating rod 1132 will not generate friction with the inner wall surface of the mounting port 111b, thereby reducing the friction and wear of the rotating rod 1132 and the friction and wear of the shell 111, and increasing the structural reliability of the earphone 10.

[0071] For some examples, see Figure 5 and Figure 6 The code disk 1121 is provided with a connecting hole 112a. The rotating rod 1132 is passed through the connecting hole 112a. The rotating rod 1132 can be circumferentially locked with at least a portion of the connecting hole 112a and drive the code disk 1121 to rotate through the connecting hole 112a.

[0072] That is, the rotation rod 1132 and the connecting hole 112a are locked in the circumferential direction, so that there is no relative rotation between the knob 113 and the code disk 1121.

[0073] In this embodiment, a rotating rod 1132, which passes through the connecting hole 112a, forms a circumferentially fixed engagement with at least a portion of the connecting hole 112a, enabling the rotating rod 1132 to drive the code disk 1121 to rotate synchronously without rotational offset, thereby increasing the rotational stability of the rotating rod 1132 and the code disk 1121. The rotational position or amount of the knob 113 is converted into an electronic signal by the encoder 112 to control the volume and power on / off of the earphones 10.

[0074] There is no limitation on the manner of achieving the circumferential anti-rotation fit between the rotating rod 1132 and the connecting hole 112a.

[0075] Exemplarily, at least a portion of the connecting hole 112a has a square cross-sectional shape. The cross-sectional shape of at least a portion of the portion where the rotary rod 1132 extends into the connecting hole 112a is square. The cross-sectional shape of at least a portion of the connecting hole 112a may be square, either for the entire connecting hole 112a or for a portion of the connecting hole 112a. Similarly, the cross-sectional shape of at least a portion of the portion where the rotary rod 1132 extends into the connecting hole 112a is square. The cross-sectional shape of the entire portion where the rotary rod 1132 extends into the connecting hole 112a may be square, or for a portion of the portion. This achieves a circumferentially anti-rotation fit between the rotary rod 1132 and at least a portion of the connecting hole 112a.

[0076] It should be noted that since the rotating rod 1132 needs to extend into the connecting hole 112a, the outer diameter of the rotating rod 1132 needs to be no larger than the inner diameter of the connecting hole 112a. For example, if the cross-section is rectangular, the length of the long side of the rectangular cross-section of the rotating rod 1132 is smaller than the length of the long side of the rectangular cross-section of the connecting hole 112a.

[0077] For example, the cross-sectional shape of at least a portion of the connecting hole 112 a and the cross-sectional shape of at least a portion of the rotating rod 1132 may be square, circular, polygonal or other shapes, which are not limited here.

[0078] For some examples, see Figures 2 to 6 The sound unit 11 includes a snap ring 114. The snap ring 114 is disposed between the cavity wall of the accommodating cavity 111a and the encoder 112. The snap ring 114 is sleeved on the outer periphery of the rotating rod 1132 to limit the rotating rod 1132 in the axial direction.

[0079] It should be noted that the snap ring 114 has a through hole, and an opening is provided on one side of the through hole, so that the rotating rod 1132 can be inserted into the through hole from the opening, so that the snap ring 114 is sleeved on the outer periphery of the rotating rod 1132; a part of the snap ring 114 can also extend and bend toward one end along the thickness direction of the shell 111, so that during assembly, the snap ring 114 can be assembled on the rotating rod 1132 by applying force to the bent part, making assembly easier. At the same time, the bent part can also avoid the shell 111, reducing the space occupied by the snap ring 114 in the thickness direction of the shell 111.

[0080] The snap ring 114 is disposed between the cavity wall of the accommodating cavity 111 a and the encoder 112 . That is, there is a certain space between the cavity wall of the accommodating cavity 111 a and the encoder 112 for the snap ring 114 to extend into and be sleeved on the outer periphery of the rotating rod 1132 .

[0081] The snap ring 114 limits the axial position of the rotating rod 1132 , and the axial position can be limited by the snap ring 114 contacting the stepped end surface on the rotating rod 1132 .

[0082] In this embodiment, the provision of the retaining ring 114 can limit the axial position of the rotating rod 1132 , thereby increasing the installation stability of the rotating rod 1132 , reducing the probability of the rotating rod 1132 falling out of the accommodating cavity 111 a , and increasing the structural reliability of the earphone 10 .

[0083] For some examples, see Figure 5 and Figure 6 The rotating rod 1132 includes a first rod segment 1132a and a second rod segment 1132b connected to each other. The encoder 112 is provided with a connecting hole 112a. The second rod segment 1132b is inserted into the connecting hole 112a. The outer diameter of the first rod segment 1132a is at least smaller than the outer diameter of the second rod segment 1132b on the side closest to the first rod segment 1132a. The retaining ring 114 is fixed to the outer periphery of the first rod segment 1132a and detachably abuts the end surface of the second rod segment 1132b on the side closest to the first rod segment 1132a.

[0084] The rotating rod 1132 includes a first rod segment 1132 a and a second rod segment 1132 b that are connected to each other. That is, the first rod segment 1132 a and the second rod segment 1132 b are sequentially connected along the axial direction of the rotating rod 1132 .

[0085] The second rod segment 1132b is passed through the connecting hole 112a. That is, the second rod segment 1132b is located at the end of the rotating rod 1132 away from the rotating cap 1131. The rotating cap 1131, the first rod segment 1132a and the second rod segment 1132b are sequentially connected along the axial direction.

[0086] The outer diameter of the first rod segment 1132a is at least smaller than the outer diameter of the second rod segment 1132b on the side close to the first rod segment 1132a. In other words, the outer diameter of the second rod segment 1132b can be variable. As long as the outer diameter of the second rod segment 1132b on the side close to the first rod segment 1132a is larger than the outer diameter of the first rod segment 1132a, a step can be formed at the transition position.

[0087] An end surface of the second rod segment 1132b close to the first rod segment 1132a is a stepped end surface at a transition position between the second rod segment 1132b and the first rod segment 1132a.

[0088] The snap ring 114 is clamped on the outer periphery of the first rod segment 1132a and is detachably abutted against the end face of one side of the second rod segment 1132b close to the first rod segment 1132a, so that the snap ring 114 can abut against the stepped end face of the transition position axially, thereby realizing the axial limitation of the rotating rod 1132 by the snap ring 114, improving the situation where the rotating rod 1132 falls out of the connecting hole 112a and the knob 113 falls out of the shell 111.

[0089] For some examples, see Figure 2 and Figure 5 The outer surface of the housing 111 is partially recessed to form a groove 111c. The screw cap 1131 is partially disposed in the groove 111c. The mounting opening 111b penetrates the wall of the groove 111c.

[0090] The installation opening 111 b passes through the groove wall of the groove 111 c , which means that the installation opening 111 b passes through the groove wall on one side of the groove 111 c close to the accommodating cavity 111 a .

[0091] Exemplarily, the mounting port 111b can be located roughly at the center of the groove 111c. The notch shape of the groove 111c is roughly circular and matches the screw cap 1131, so that the entire outer periphery of the screw cap 1131 can be partially embedded in the groove 111c. The groove 111c can limit the screw cap 1131. At the same time, the cooperation between the knob 113 and the groove 111c can also increase the contact area between the knob 113 and the shell 111, further increasing the installation stability of the knob 113.

[0092] A groove 111c is formed by recessing part of the outer surface of the shell 111 to accommodate part of the screw cap 1131, thereby reducing the exposed size of the screw cap 1131. While increasing the installation stability of the knob 113, the degree of damage to the appearance of the earphone 10 caused by the screw cap 1131 is reduced, making the appearance of the sound unit 11 more beautiful.

[0093] For some examples, see Figure 2 and Figure 5The sound unit 11 includes a circuit board 115 disposed in the accommodating cavity 111 a. The circuit board 115 is disposed in the accommodating cavity 111 a and is electrically connected to an end of the encoder 112 away from the knob 113.

[0094] It should be noted that the circuit board 115 may include a first circuit board and a second circuit board, wherein the first circuit board is a main board 1151, which is used to realize the main functions of the headset 10, and the second circuit board is a flexible printed circuit 1152 (FPC), which is used to connect the encoder 112 and the main board 1151.

[0095] It should be noted that the flexible circuit board 1152 is a highly reliable and flexible printed circuit board made of polyimide or polyester film as a base material, and has the characteristics of high wiring density, light weight, thin thickness, and good bendability.

[0096] The circuit board 115 is electrically connected to the end of the encoder 112 away from the knob 113, which can shorten the connection line between the encoder 112 and the circuit board 115. At the same time, the flexible circuit board 1152 can bend and deform in the accommodating cavity 111a, so that it can flexibly avoid other components of the shell 111 and electrically connect the main board 1151 to the encoder 112, making the structure of the sound unit 11 more compact.

[0097] In some embodiments, see Figures 1 to 5 The earphone 10 further includes a connecting unit 12. The connecting unit 12 includes an ear hook portion 121. One end of the ear hook portion 121 is connected to the housing 111.

[0098] It should be noted that the connecting unit 12 may further include a battery portion 122 , and both ends of the ear hook portion 121 are respectively connected to the battery portion 122 and the housing 111 of the sound unit 11 .

[0099] The ear hook portion 121 can generate elastic deformation under the action of external force, and the ear hook portion 121 can cooperate with the auricle to hang the earphone 10 on the ear.

[0100] In other embodiments, the connecting unit 12 includes an ear clip portion. One end of the ear clip portion is connected to the housing 111. In this way, the ear clip portion clips the earphone 10 on the ear, thereby achieving wearing of the earphone 10.

[0101] For some examples, see Figure 4 The ratio of the diameter of the screw cap 1131 to the thickness of the housing 111 is 0.25 to 0.75. For example, the ratio is 0.25, 0.3, 0.4, 0.5, 0.6, 0.7 or 0.75, etc., which is not limited here.

[0102] like Figure 4 As shown, the diameter of the screw cap 1131 is represented by c, and the dimension of the shell 111 along the thickness direction is represented by d.

[0103] It should be noted that the dimensions of different components in the three directions in the same absolute coordinate system are different. Generally, the length, width and thickness of an object are determined according to the dimensions of the object extending in the three directions, with length > width > thickness.

[0104] In the embodiment of the present application, the sound unit 11 and the shell 111 have the same thickness direction.

[0105] In this way, the ratio of the diameter of the screw cap 1131 and the thickness direction of the shell 111 is set, which can provide the user with sufficient contact area with the screw cap 1131, so that the user can turn the earphone 10 on and off and adjust the volume by rotating the screw cap 1131. At the same time, the overall size of the screw cap 1131 is relatively appropriate, which increases the appearance of the earphone 10 and facilitates the miniaturization design of the earphone 10 to enhance the user experience.

[0106] For some examples, see Figure 4 The diameter of the screw cap 1131 is 3 mm to 8 mm. For example, the diameter of the screw cap 1131 can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or 8 mm, etc., which is not limited here.

[0107] Among them, mm is the abbreviation of millimeter, which stands for millimeter and is a unit of length.

[0108] It should be noted that, corresponding to the range of the ratio of the diameter of the screw cap 1131 to the dimension of the housing 111 along the thickness direction, the dimension of the housing 111 along the thickness direction can range from 4 mm to 32 mm. For example, the dimension of the housing 111 along the thickness direction can be 4 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 16 mm, 20 mm, 30 mm, or 32 mm, etc., without limitation.

[0109] By setting the diameter of the screw cap 1131 to 3 mm-8 mm, the screw cap 1131 occupies less space, thereby improving the aesthetics of the knob 113 and the sound unit 11 .
