[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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 creative work should fall within the scope of protection of the present invention.
[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.
[0040] Figure 1 A schematic diagram of the structure of a left-right adaptive headset provided by an embodiment of the present invention. Figure 2 A schematic diagram of the electrical principle of a first detection sensor provided by an embodiment of the present invention, such as Figure 1 and Figure 2As shown, the left and right ear adaptive earphones include an earphone body 10, a controller ( Figure 1 The first detection sensor 20 and the controller are both arranged in the earphone body 10; the earphone body 10 includes a first surface 11 and a second surface 12 arranged relatively to each other along a first direction (Y direction as shown in the figure); the first detection sensor 20 is used to detect the orientation of the first surface 11 and the orientation of the second surface 12; the controller is electrically connected to the first detection sensor 20, and is used to control the channel output of the left and right ear adaptive headphones according to the orientation of the first surface 11 and the orientation of the second surface 12.
[0041] Specifically, as a comparative example, the ear clip earphones in the prior art have a left earphone and a right earphone. Since the left earphone is fixed to output the left channel and the right earphone is fixed to output the right channel, general users need to distinguish the left earphone and the right earphone before wearing them, that is, wear the left earphone on the left ear and the right earphone on the right ear. Otherwise, it will affect the sound quality heard, and thus affect the user experience.
[0042] Specifically, the earphone body 10 of each earphone monomer includes a sound-generating section 101, a fixed section 102, and a connecting section 103 connecting the sound-generating section 101 and the fixed section 102. The connecting section 103 can be a bendable bracket, so that the sound-generating section 101 and the fixed section 102 are respectively located in front of and behind the user's ear. Exemplarily, the bracket is made of soft and skin-friendly silicone material to ensure comfort when wearing. The sound-generating section 101 can be worn in front of the ear, and acoustic modules such as speakers and microphones can be provided in the sound-generating section 101. The fixed section 102 can be worn behind the ear, and a power module, a controller, a noise reduction module, and a communication module can be provided in the fixed section 102. The embodiment of the present invention does not specifically limit the electronic components inside the sound-generating section 101 and the fixed section 102.
[0043] Exemplarily, the first detection sensor 20 can be arranged in the sound-generating subsection 101. The sound-generating subsection 101 includes a first surface 11 and a second surface 12 arranged relatively along a first direction Y, so that when the earphone is worn on the left ear, the first surface 11 faces upward and the second surface 12 faces downward, and when the earphone is worn on the right ear, the first surface 11 faces downward and the second surface 12 faces upward. The embodiment of the present invention can detect the orientation of the first surface 11 and the orientation of the second surface 12 by setting the first detection unit 20. Exemplarily, when the first surface 11 faces upward and the second surface 12 faces downward, the first detection sensor 20 can output a level signal to the controller 30, and the controller controls the speaker to output the left channel; when the first surface 11 faces downward and the second surface 12 faces upward, the first detection sensor 20 outputs another level signal to the controller 30, and the controller controls the speaker to output the right channel, so that the user does not need to distinguish the wearing position of the earphone before wearing. After the user wears it, the earphone can adapt to the left and right ears according to the wearing position of the user, and then output the corresponding channel, thereby improving the convenience of use and enhancing the user's experience.
[0044] The left and right ear adaptive headphones provided by the embodiment of the present invention, by setting a first detection sensor in the earphone body, the first detection sensor can detect the orientations of two surfaces of the earphone body that are relatively set, that is, the orientation of the first surface and the orientation of the second surface. In this way, the wearing position of the earphone can be determined by detecting the orientations of the two surfaces that are relatively set, and then the controller is electrically connected to the first sensor through the controller. The controller can control the channel output of the left and right ear adaptive headphones according to the orientation of the first surface and the orientation of the second surface, that is, the controller adjusts the channel of the speaker according to the wearing position of the earphone, and then the user does not need to distinguish between the left and right channels before wearing the earphone, which improves the convenience of using the earphone and enhances the user experience.
[0045] Optional, continue to refer to Figure 2 The first detection sensor 20 includes a first detection surface 201 and a second detection surface 202 which are arranged opposite to each other along the first direction Y; the first detection surface 201 is arranged parallel to the first surface 11, and the second detection surface 202 is arranged parallel to the second surface 12.
[0046] For further information, please refer to Figure 1 and Figure 2The first detection surface 201 includes a first conductive section 2011 and the second detection surface 202 includes a second conductive section 2021; the first detection sensor 20 includes a first gravity unit 21, the first gravity unit 21 includes a first conductive slider 211 and a first cavity 212 extending along a first direction Y and a first fixed conductive block 213; the first conductive slider 211 is located in the first cavity 212 and is slidably connected to the first fixed conductive block 213; the first conductive slider 211 is used to slide in the first cavity 212 along the first direction Y.
[0047] Specifically, since the first conductive slider 211 has a certain weight, the first conductive slider 211 will slide in the first cavity 212 when the user wears the earphone. Since the first conductive sub-portion 2011, the second conductive sub-portion 2021, the first conductive slider 211 and the first fixed conductive block 213 are all conductive, when the first detection surface 201 faces upward and the second detection surface 202 faces downward, that is, the first surface 11 faces upward and the second surface 12 faces downward, the first conductive slider 211, the second conductive sub-portion 2021 and the first fixed conductive block 213 are electrically connected, so that the output end of the first detection sensor 20 can output a level signal to the controller, and the controller controls the speaker to output the left channel. When the first detection surface 201 faces downward and the second detection surface 202 faces upward, that is, the first surface 11 faces downward and the second surface 12 faces upward, the first conductive slider 211, the first conductive sub-portion 2011 and the first fixed conductive block 213 are electrically connected, so that the output end of the first detection sensor 20 can output another level signal to the controller, and the controller controls the speaker to output the right channel. Since the two level signals are different, the orientations of the first surface and the second surface can be determined according to the output level signals, so that the first detection sensor can detect the orientations of the two relatively arranged surfaces, thereby achieving left and right ear adaptation of the earphone.
[0048] It should be noted that Figure 2 Only the technical solution in which the first conductive slider 211 is a conductive metal ball is shown. It can be understood that the first conductive slider 211 can also be a conductive metal slider.
[0049] It should be noted that since the first conductive slider 211 is not fixed in the first cavity 202, but slides in the first cavity 212 due to its own gravity, the first conductive slider 211 cannot be fixedly electrically connected to the first fixed conductive block 213. Instead, when the first conductive slider 211 slides to the first conductive section or the second conductive section, the conductive section, the conductive slider and the fixed conductive block are electrically connected, and the first detection sensor has an output signal.
[0050] It should be noted that, by providing the first detection sensor, the left and right ear adaptation of the earphone can be achieved when the human body is in a normal upright or sitting posture.
[0051] Optional, continue to refer to Figure 2 The first detection sensor 20 also includes a first level output unit 203; a first end of the first level output unit 203 is electrically connected to the first fixed conductive block 213, and is used to output a level signal according to the position of the first conductive block slider 213.
[0052] Specifically, as a feasible implementation, when the first conductive sub-section 2011 faces upward and the second conductive sub-section 2021 faces downward, the first conductive slider 211, the second conductive sub-section 2021 and the first fixed conductive block 213 are electrically connected, so that the first level output unit 203 can output a high level signal. When the first conductive sub-section 2011 faces downward and the second conductive sub-section 2021 faces upward, the first conductive slider 211, the first conductive sub-section 2011 and the first fixed conductive block 213 are electrically connected, so that the first level output unit 203 can output a low level signal.
[0053] As another feasible implementation, when the first conductive segment 2011 faces upward and the second conductive segment 2021 faces downward, the first conductive slider 211, the second conductive segment 2021 and the first fixed conductive block 213 are electrically connected, so that the first level output unit 203 can output a low level signal. When the first conductive segment 2011 faces downward and the second conductive segment 2021 faces upward, the first conductive slider 211, the first conductive segment 2011 and the first fixed conductive block 213 are electrically connected, so that the first level output unit 203 can output a high level signal.
[0054] Optional, continue to refer to Figure 2 The first detection sensor 20 also includes: a first power supply terminal 204, a first ground terminal 205 and a first output terminal 206; the controller is electrically connected to the first output terminal 206, and is used to receive the level signal output by the first output terminal 206, and control the channel output of the left and right ear adaptive headphones according to the level signal; the first conductive subdivision 2011 and the second end of the first level output unit 203 are both electrically connected to the first power supply terminal 204, the second conductive subdivision 2021 and the third end of the first level output unit 203 are both electrically connected to the first ground terminal 205, and the first output terminal 206 is also electrically connected to the fourth end of the first level output unit 203; or, the first conductive subdivision 2011 and the second end of the first level output unit 203 are both electrically connected to the first ground terminal 205, the second conductive subdivision 2021 and the third end of the first level output unit 203 are both electrically connected to the first power supply terminal, and the first output terminal 206 is electrically connected to the fourth end of the first level output unit 203.
[0055] Specifically, when the first conductive slider 211, the first conductive sub-section 2011 and the first fixed conductive block 213 are electrically connected, the user wears the earphone on the right ear; when the first conductive slider 211, the second conductive sub-section 2021 and the first fixed conductive block 213 are electrically connected, the user wears the earphone on the left ear. As a feasible implementation, when the first conductive slider 211, the first conductive sub-section 2011 and the first fixed conductive block 213 are electrically connected, a low level can be output to the first level output unit 203, and the first level output unit 203 transmits the low level signal to the controller through the first output terminal 206, so that the controller controls the speaker to output the right channel; when the first conductive slider 211, the second conductive sub-section 2021 and the first fixed conductive block 213 are electrically connected, a high level can be output to the first level output unit 203, and the first level output unit 203 transmits the high level signal to the controller through the first output terminal 206, so that the controller controls the speaker to output the left channel.
[0056] As another feasible implementation, when the first conductive slider 211, the first conductive division 2011 and the first fixed conductive block 213 are electrically connected, a high level can be output to the first level output unit 203, and the first level output unit 203 transmits the high level signal to the controller through the first output terminal 206, so that the controller controls the speaker to output the right channel; when the first conductive slider 211, the second conductive division 2021 and the first fixed conductive block 213 are electrically connected, a low level can be output to the first level output unit 203, and the first level output unit 203 transmits the low level signal to the controller through the first output terminal 206, so that the controller controls the speaker to output the left channel.
[0057] Optional, Figure 3 The electrical principle diagram of the second detection sensor provided in this embodiment of the present invention is as follows: Figure 1 and Figure 3 As shown, the left and right ear adaptive earphones further include: a second detection sensor 30; the earphone body 10 includes a Figure 1 The third surface 13 and the fourth surface 14 are relatively arranged along the second direction X (X direction shown in the figure); the second direction X intersects with the first direction Y; the second detection sensor 30 includes a third detection surface 301 and a fourth detection surface 302 relatively arranged along the second direction X; the third detection surface 301 is arranged in parallel with the third surface 13, and the fourth detection surface 302 is arranged in parallel with the fourth surface 14; the second detection sensor 30 is used to detect the orientation of the third surface 13 and the orientation of the fourth surface 14; the controller is also electrically connected to the second detection sensor 30, and is used to control the channel output of the left and right ear adaptive headphones according to the orientation of the third surface 13 and the orientation of the fourth surface 14.
[0058] Specifically, the line between the third surface 13 and the fourth surface 14 intersects with the line between the first surface 11 and the second surface 12. The first detection sensor 20 can detect the orientation of the first surface 11 and the second surface 12, and the second detection sensor 30 can detect the orientation of the third surface 13 and the fourth surface 14, thereby realizing all-round adaptation of the left and right ears.
[0059] Exemplarily, when the user wears the earphones in a side-lying or tilted head position, the second detection sensor 30 is set to detect the orientation of the third surface 13 and the fourth surface 14. For example, when the user is in a side-lying position and when the earphones are worn on the left ear, the fourth surface 14 faces upward and the third surface 13 faces downward. In this way, the second detection sensor 30 can output a level signal to the controller, and the controller controls the speaker to output the left channel; when the earphones are worn on the right ear, the fourth surface 14 faces downward and the third surface 13 faces upward. In this way, the second detection sensor 30 can output another level signal to the controller, and the controller controls the speaker to output the right channel. Therefore, the user does not need to distinguish the wearing position of the earphones before wearing them. After the user wears them, the earphones can adapt to the left and right ears according to the wearing position of the user, and then output the corresponding channels, thereby improving convenience of use and enhancing the user experience.
[0060] Exemplarily, the first direction may be arranged perpendicular to the second direction.
[0061] Optional, continue to refer to Figure 3 The third detection surface 301 includes a third conductive section 3011, and the fourth detection surface 302 includes a fourth conductive section 3021; the second detection sensor 30 also includes a second gravity unit 31, and the second gravity unit 31 includes a second conductive slider 311 and a second cavity 312 extending along the second direction X and a second fixed conductive block 313; the second conductive slider 311 is located in the second cavity 312 and is slidably connected to the second fixed conductive block 313; the second conductive slider 311 is used to slide in the second cavity 312 along the second direction X.
[0062] Specifically, the second conductive slider 311, the fourth conductive subdivision 3021 and the second fixed conductive block 313 are electrically connected, and the user wears the earphone on the right ear; the second conductive slider 311, the third conductive subdivision 3021 and the second fixed conductive block 313 are electrically connected, and the user wears the earphone on the left ear. As the second conductive slider 311 has a certain weight, when the user wears the earphone and lies sideways or tilts his head, the second conductive slider 311 will slide in the second cavity 312. As the third conductive subdivision 3011, the fourth conductive subdivision 3021, the second conductive slider 311 and the second fixed conductive block 313 are all conductive, when the third conductive subdivision 3011 faces upward and the fourth conductive subdivision 3021 faces downward, that is, when the third surface 13 faces upward and the fourth surface 14 faces downward, the second conductive slider 311, the fourth conductive subdivision 3021 and the second fixed conductive block 313 are electrically connected, so that the output end of the second detection sensor 30 can output a level signal to the controller, and the controller controls the speaker to output the right channel. When the third conductive segment 3011 faces downward and the fourth conductive segment 3021 faces upward, that is, the third surface 13 faces downward and the fourth surface 14 faces upward, the second conductive slider 311, the third conductive segment 3011 and the second fixed conductive block 313 are electrically connected, so that the output end of the second detection sensor 30 can output another level signal to the controller, and the controller controls the speaker to output the left channel. Since the two level signals are different, the orientations of the third surface and the fourth surface can be determined according to the output level signals, so that the first detection sensor can detect the orientations of the two surfaces arranged opposite to each other, and the left and right ears of the earphone can be self-adapted.
[0063] Exemplarily, the second conductive slider 311 may be a conductive metal slider or a conductive metal ball.
[0064] It can be understood that the second detection sensor may further include a level output unit, a power supply terminal, a ground terminal and an output terminal.
[0065] It should be noted that the first detection sensor and the second detection sensor can be set independently or integrated together, that is, the first gravity unit and the second gravity unit are integrated into one sensor. In this way, on the one hand, it is possible to detect the orientation of surfaces relatively set in two directions in the earphone body, and on the other hand, the setting method is simple.
[0066] Exemplarily, the embodiment of the present invention is described by taking the left and right ear adaptive headphones including two detection sensors as an example. It can be understood that a third detection sensor may also be included. Figure 4 A schematic diagram of a human body tilt angle provided by an embodiment of the present invention, continue to refer to Figure 1 and Figure 4, the third detection sensor can be used to detect the orientation of two relatively arranged surfaces in the front-to-back wearing direction parallel to the human body. The front-to-back wearing direction of the human body can be understood as the direction from the front of the human ear to the back of the ear. Taking the normal upright state of the human body as 0° as an example, the third detection sensor will undergo a logical change when the human body leans forward or lies back more than 90°. Similarly, when the human body tilts from the upright direction to the left or right, the third detection sensor will undergo a logical change only when it exceeds 90°. This can further ensure the detection accuracy and achieve self-adaptation in more application scenarios such as lying down or nodding.
[0067] Optional, continue to refer to Figure 3 The second detection sensor 30 also includes a second level output unit 303; a first end of the second level output unit 303 is electrically connected to the second fixed conductive block 313, and is used to output a level signal according to the position of the second conductive block slider 311.
[0068] Specifically, as a feasible implementation, when the third conductive segment 3011 faces upward and the fourth conductive segment 3021 faces downward, the second conductive slider 311, the fourth conductive segment 3021 and the second fixed conductive block 313 are electrically connected, so that the second level output unit 303 can output a high level signal. When the third conductive segment 3011 faces downward and the fourth conductive segment 3021 faces upward, the second conductive slider 311, the third conductive segment 3011 and the second fixed conductive block 313 are electrically connected, so that the second level output unit 303 can output a low level signal.
[0069] As another feasible implementation, when the third conductive segment 3011 faces upward and the fourth conductive segment 3021 faces downward, the second conductive slider 311, the fourth conductive segment 3021 and the second fixed conductive block 313 are electrically connected, so that the second level output unit 303 can output a low level signal. When the third conductive segment 3011 faces downward and the fourth conductive segment 3021 faces upward, the second conductive slider 311, the third conductive segment 3011 and the second fixed conductive block 313 are electrically connected, so that the second level output unit 303 can output a high level signal.
[0070] Optional, continue to refer to Figure 3The second detection sensor 30 also includes: a second power supply terminal 304, a second ground terminal 305 and a second output terminal 306; the controller is electrically connected to the second output terminal 306, for receiving the level signal output by the second output terminal 306, and controlling the channel output of the left and right ear adaptive headphones according to the level signal; the third conductive division 3011 and the second end of the second level output unit 303 are both electrically connected to the second power supply terminal 304, the fourth conductive division 3021 and the third end of the second level output unit 303 are both electrically connected to the second ground terminal 305, and the second output terminal 306 is also electrically connected to the fourth end of the second level output unit 303; or, the third conductive division 3011 and the second end of the second level output unit 303 are both electrically connected to the second ground terminal 305, the fourth conductive division 3021 and the third end of the second level output unit 303 are both electrically connected to the second power supply terminal 204, and the second output terminal 206 is electrically connected to the fourth end of the second level output unit 303.
[0071] Specifically, when the second conductive slider 311, the third conductive sub-section 3011 and the second fixed conductive block 313 are electrically connected, the user wears the earphone on the right ear; when the second conductive slider 311, the fourth conductive sub-section 3021 and the second fixed conductive block 313 are electrically connected, the user wears the earphone on the left ear. As a feasible implementation, when the second conductive slider 311, the third conductive sub-section 3011 and the second fixed conductive block 313 are electrically connected, a low level can be output to the second level output unit 303, and the second level output unit 303 transmits the low level signal to the controller through the second output terminal 306, so that the controller controls the speaker to output the right channel; when the second conductive slider 311, the fourth conductive sub-section 3021 and the second fixed conductive block 313 are electrically connected, a high level can be output to the second level output unit 303, and the second level output unit 303 transmits the high level signal to the controller through the second output terminal 306, so that the controller controls the speaker to output the left channel.
[0072] As another feasible implementation, when the second conductive slider 311, the third conductive division 3011 and the second fixed conductive block 313 are electrically connected, a high level can be output to the second level output unit 303, and the second level output unit 303 transmits the high level signal to the controller through the second output terminal 306, so that the controller controls the speaker to output the right channel; when the second conductive slider 311, the fourth conductive division 3021 and the second fixed conductive block 313 are electrically connected, a low level can be output to the second level output unit 303, and the second level output unit 303 transmits the low level signal to the controller through the second output terminal 306, so that the controller controls the speaker to output the left channel.
[0073] It can be understood that the first power terminal and the second power terminal can be the same power terminal, and the first ground terminal and the second ground terminal can be the same ground terminal.
[0074] Optional, continue to refer to Figure 2 , along the first direction Y, the extension length of the first fixed conductive block 213 is greater than or equal to the distance between the first detection surface 201 and the second detection surface 202 .
[0075] Specifically, along the first direction Y, the extension length of the first fixed conductive block 213 is greater than or equal to the distance between the first detection surface 201 and the second detection surface 202, so that when the first conductive slider 211 slides in the first cavity 212, the electrical connection effect with the first conductive division 2011, the first conductive slider 211 and the first fixed conductive block 213, or the electrical connection effect between the second conductive division 2021, the first conductive slider 211 and the first fixed conductive block 213 can be ensured, thereby ensuring the stability and reliability of the first detection sensor.
[0076] Optionally, the left and right ear adaptive headphones further include: an acceleration sensor; and a controller electrically connected to the acceleration sensor, for controlling the channel output of the left and right ear adaptive headphones according to a sensing signal of the acceleration sensor.
[0077] Specifically, an acceleration sensor may be provided inside the earphone body to sense the movement of the user's head. When the acceleration value detected by the acceleration sensor is 0, it indicates that the current user is in a static state. At this time, the user's posture is interpreted to prevent the earphone from shaking during exercise, thereby preventing the misjudgment of the displacement of the first conductive slider or the second conductive slider. The detection of three-dimensional coordinates by the acceleration sensor can complete the adaptation of the left and right channels of the user in any free posture, which can further ensure the adaptation of the earphone.
[0078] Optional, continue to refer to Figure 2 The first conductive slider 211 includes a first conductive sphere or a first conductive rectangular block, that is, the shape of the first conductive slider 211 can be circular or rectangular, so that the first detection sensor can be diversified.
[0079] Specifically, as a feasible implementation, the first conductive slider 211 includes a first conductive rectangular block. By setting the shape of the first conductive slider 211 to be a cube, the contact area between the first conductive slider 211 and the first conductive section 2011, the second conductive section 2021 and the first fixed conductive block 213 can be increased, which is beneficial to ensure the conductive effect and thus improve the stability of the sensor.
[0080] As a feasible implementation, the first conductive slider 211 includes a first conductive sphere. By setting the shape of the first conductive slider 211 to be a sphere, it is beneficial for the first conductive slider 211 to slide in the first cavity 212, thereby improving the detection accuracy of the sensor.
[0081] Optional, continue to refer to Figure 2 The level output unit 203 includes a metal oxide semiconductor field effect transistor. When the first conductive slider 211 slides in the first cavity 212, a level signal is output to the control end of the metal oxide semiconductor field effect transistor, thereby controlling the on and off of the metal oxide semiconductor field effect transistor. In this way, the orientations of the two surfaces arranged relatively along the first direction can be detected according to the on and off of the metal oxide semiconductor field effect transistor.
[0082] Exemplarily, the level output unit 203 may also be composed of a resistor and two transistors. Specifically, one end of the resistor is electrically connected to the first fixed conductive block, and the other end is electrically connected to the two transistors respectively.
[0083] It should be noted that when the user wears headphones, movement or shaking may cause the sensor to output erroneous signals to a certain extent. The algorithm can be optimized to eliminate events with low probability. For example, the output signal of the sensor can be counted at a certain time and recorded. For example, 100 times per second, and continuous statistics for 10 seconds. Due to the effect of gravity, the situation where the probability of the signal occurring is greater than 70% can be defined as the conductive slider pointing downward. The probability is 30%-70%, and no judgment is made. The situation where the probability is less than 30% is defined as the conductive slider pointing upward. (The specific ratio can be counted based on the actual situation).
[0084] In summary, the technical solution provided by the embodiment of the present invention, by setting a first detection sensor in the earphone body, the first detection sensor can detect the orientations of two surfaces of the earphone body that are relatively set, that is, the orientation of the first surface and the orientation of the second surface, so that the wearing position of the earphone can be determined by detecting the orientations of the two surfaces that are relatively set, and then through the controller electrically connected to the first sensor, the controller can control the channel output of the left and right ear adaptive earphones according to the orientation of the first surface and the orientation of the second surface, that is, the controller adjusts the channel of the speaker according to the wearing position of the earphone, and then the user does not need to distinguish between the left and right channels before wearing the earphone, which improves the convenience of using the earphone and enhances the user experience.
