Description

[0002] Wireless earbuds or open-back sports earbuds, when the left and right earbuds have the same design, can be placed in the charging case or worn in either ear. However, when worn in either ear, to play stereo audio files, the left ear needs to play the left channel audio, and the right ear needs to play the right channel audio. Therefore, it is necessary to adapt to the fit of the left and right earbuds.

[0003] Currently, wireless headphones or open-back sports headphones lack a good way to identify up and down directions, and the headphones cannot adapt to the wearing of the left and right ears, thus affecting the user experience. Utility Model Content

[0006] The first conductive portion is connected to the A surface of the sensor chip arranged along the first direction, and the second conductive portion is connected to the B surface of the sensor chip arranged opposite to the A surface of the sensor chip.

[0011] The first conductive portion and the second terminal of the level output unit are both electrically connected to the power supply terminal, the second conductive portion and the third terminal of the level output unit are both electrically connected to the ground terminal, and the output terminal is electrically connected to the fourth terminal of the level output unit.

[0012] or,

[0013] The first conductive portion and the second terminal of the level output unit are both electrically connected to the ground terminal, the second conductive portion and the third terminal of the level output unit are both electrically connected to the power supply terminal, and the output terminal is electrically connected to the fourth terminal of the level output unit.

[0014] Optionally, along the first direction, the extension length of the first fixed conductive block is greater than or equal to the extension length of the first cavity.

[0015] Optionally, the sensor further includes a third conductive portion and a fourth conductive portion;

[0016] The third conductive portion is connected to the A surface of the sensor chip arranged along the second direction, and the fourth conductive portion is connected to the B surface of the sensor chip arranged opposite to the A surface of the sensor chip; the second direction intersects the first direction;

[0017] The gravity module further includes a second gravity unit, which includes a second conductive slider, a second cavity extending along the second direction, and a second fixed conductive block; the second conductive slider is located in the second cavity and is slidably connected to the second fixed conductive block; the second conductive slider is used to slide within the second cavity along the second direction.

[0024] The technical solution provided by this utility model embodiment involves setting a first conductive slider in a first gravity unit. During sensor movement, the first conductive slider slides within a first cavity due to its own gravity. For example, the two surfaces arranged opposite each other along a first direction can be surface A and surface B of a sensor chip. When surface B faces down, the first conductive slider slides from surface A to surface B due to gravity, meaning surface B of the sensor chip, the first conductive slider, and the first fixed conductive block are connected, thus outputting a voltage level signal. When surface A faces down, the first conductive slider slides from surface B to surface A due to gravity, meaning surface A of the sensor chip, the first conductive slider, and the first fixed conductive block are connected, thus outputting a different voltage level signal. Because the voltage levels connected to the first conductive portion and the second conductive portion are different, the voltage level signals output when the first conductive slider slides to the first conductive portion and the second conductive portion are different, thus allowing the orientation of the two oppositely arranged surfaces to be determined based on the voltage level signals.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0033] Figure 1 An electrical schematic diagram of the first type of sensor provided for an embodiment of this utility model is shown below. Figure 1 As shown, the sensor 200 includes: at least one sensor chip, a first conductive portion 10, a second conductive portion 20, and a gravity module 30; the first conductive portion 10 is coupled to the sensor along a first direction (e.g., along a first direction). Figure 1 The sensor chip A side (shown in the Y direction) is connected to the sensor chip B side, which is opposite to the sensor chip A side; the gravity module 30 includes a first gravity unit 301, which includes a first conductive slider 3011, a first cavity 3013 extending along the first direction Y, and a first fixed conductive block 3012; the first conductive slider 3011 is located in the first cavity 3013 and is slidably connected to the first fixed conductive block 3012; the first conductive slider 3011 is used to slide along the first direction Y in the first cavity 3013.

[0034] Specifically, the two surfaces positioned opposite each other along the first direction Y can be understood as the two surfaces of the earpiece in a wireless or open-back sports headphone, i.e., surface A and surface B of the sensor chip. The first conductive portion 10 is connected to surface A of the sensor chip, and the second conductive portion 20 is connected to surface B of the sensor chip, so as to detect the orientation of surface A and surface B.

[0035] Specifically, the first gravity module includes a first cavity 3013 extending along the first direction Y, and a first conductive slider 3011 located within the first cavity 3013. Since the first conductive slider 3011 has a certain weight, it will slide within the first cavity 3013 under the influence of its own gravity during sensor movement. For example, the first conductive portion 10 is connected to surface A, and the second conductive portion 20 is connected to surface B. Since the first conductive portion 10, the second conductive portion 20, the first conductive slider 3011, and the first fixed conductive block 3012 are all conductive, when surface A is facing upwards and surface B is facing downwards, the first conductive slider 3011, the second conductive portion 20, and the first fixed conductive block 3012 are electrically connected, thus allowing the sensor's output terminal to output a voltage level signal. When surface A is facing down and surface B is facing up, the first conductive slider 3011, the first conductive section 10, and the first fixed conductive block 3012 are electrically connected. In this way, the output terminal of the sensor can output another level signal. Since the two level signals are different, the orientation of surface A and surface B can be determined according to the output level signal, so as to realize the sensor's detection of the orientation of two relatively set surfaces.

[0036] Understandably, when the left and right earphones are identical, if side A is facing down, the earphone is worn in the left ear; if side B is facing down, the earphone is worn in the right ear. This way, the orientation of side A and side B can determine whether the earphone is worn in the left or right ear, and the audio output can be matched so that the earphone worn in the left ear outputs the left channel and the earphone worn in the right ear outputs the right channel, achieving self-adaptation between the left and right earphones and thus improving the user experience.

[0037] For example, the first conductive slider 3011 may be a conductive metal slider.

[0038] The sensor provided in this embodiment of the invention uses a first conductive slider in a first gravity unit. During sensor movement, the first conductive slider slides within a first cavity due to its own gravity. For example, the two surfaces arranged opposite each other along a first direction can be surface A and surface B of the sensor chip. When surface B faces down, the first conductive slider slides from surface A to surface B due to gravity, meaning surface B of the sensor chip, the first conductive slider, and the first fixed conductive block are connected, thus outputting a voltage level signal. When surface A faces down, the first conductive slider slides from surface B to surface A due to gravity, meaning surface A of the sensor chip, the first conductive slider, and the first fixed conductive block are connected, thus outputting a different voltage level signal. Because the voltage levels connected to the first conductive portion and the second conductive portion are different, the voltage level signals output when the first conductive slider slides to the first conductive portion and the second conductive portion are different, thus allowing the orientation of the two oppositely arranged surfaces to be determined based on the voltage level signals.

[0039] Optional, continue to refer to Figure 1 The sensor 200 also includes a level output unit 50; the level output unit 50 is electrically connected to the first fixed conductive block 3012 and is used to output a level signal according to the position of the first conductive slider 3011.

[0040] Specifically, taking as an example two surfaces, A and B, arranged opposite each other along the first direction Y, with the first conductive portion 10 connected to surface A and the second conductive portion connected to surface B, this will be explained. As a feasible implementation, when surface A is facing upwards and surface B is facing downwards, the first conductive slider 3011, the second conductive portion 20, and the first fixed conductive block 3012 are electrically connected, allowing the level output unit 50 to output a high-level signal. When surface A is facing downwards and surface B is facing upwards, the first conductive slider 3011, the first conductive portion 10, and the first fixed conductive block 3012 are electrically connected, allowing the level output unit 50 to output a low-level signal.

[0041] As another feasible implementation, when surface A is facing up and surface B is facing down, the first conductive slider 3011, the second conductive portion 20, and the first fixed conductive block 3012 are electrically connected, so that the level output unit 50 can output a low-level signal. When surface A is facing down and surface B is facing up, the first conductive slider 3011, the first conductive portion 20, and the first fixed conductive block 3012 are electrically connected, so that the level output unit 50 can output a high-level signal. The orientation of the two relatively arranged surfaces can be determined based on the level signal output by the level output unit 50.

[0042] Optional, Figure 2 The electrical schematic diagram of the second type of sensor provided in this embodiment of the present utility model is shown below. Figure 1 and Figure 2 The sensor 200 also includes a power supply terminal 60, a ground terminal 70, and an output terminal 80; the first conductive portion 10 and the second terminal of the level output unit 50 are both electrically connected to the power supply terminal 60, the second conductive portion 20 and the third terminal of the level output unit 50 are both electrically connected to the ground terminal 70, and the output terminal 80 is electrically connected to the fourth terminal of the level output unit 50; or, the first conductive portion 10 and the second terminal of the level output unit 50 are both electrically connected to the ground terminal 70, the second conductive portion 20 and the third terminal of the level output unit 50 are both electrically connected to the power supply terminal 60, and the output terminal 80 is electrically connected to the fourth terminal of the level output unit 50.

[0043] Specifically, the second terminal of the level output unit 50 can be understood as a control terminal. When the first conductive slider 3011, the first conductive portion 10, and the first fixed conductive block 3012 are electrically connected, a low level can be output to the level output unit 50, and the low level signal is transmitted to the output terminal 80 through the level output unit 50. When the first conductive slider 3011, the second conductive portion 20, and the first fixed conductive block 3012 are electrically connected, a high level can be output to the level output unit 50, and the high level signal is transmitted to the output terminal 80 through the level output unit 50. Alternatively, when the first conductive slider 3011, the first conductive portion 10, and the first fixed conductive block 3012 are electrically connected, a high level can be output to the level output unit 50, and the high level signal is transmitted to the output terminal 80 through the level output unit 50. When the first conductive slider 3011, the second conductive portion 20, and the first fixed conductive block 3012 are electrically connected, a low level can be output to the level output unit 50, and the low level signal is transmitted to the output terminal 80 through the level output unit 50.

[0044] Optional, continue to refer to Figure 1 Along the first direction Y, the extension length of the first fixed conductive block 3012 is greater than or equal to the extension length of the first cavity 3013.

[0045] Specifically, along the first direction Y, the extension length of the first fixed conductive block 3012 is greater than or equal to the extension length of the first cavity 3013. This ensures that when the first conductive slider 3011 slides in the first cavity 3013, it can fully contact the first fixed conductive block 3012, thereby ensuring the conductivity between the first conductive slider 3011 and the first fixed conductive block 3012, which is beneficial to improving the detection accuracy of the sensor.

[0046] Optional, Figure 3 An electrical schematic diagram of the third type of sensor provided in this embodiment of the present invention is shown below. Figure 3 As shown, the sensor 200 also includes a third conductive portion 90 and a fourth conductive portion 100; the third conductive portion 90 is connected to the sensor along the second direction (e.g., along the second direction). Figure 3 The sensor chip A surface (shown in the X direction) is connected to the sensor chip B surface (shown in the X direction), and the fourth conductive portion 100 is connected to the sensor chip B surface (shown opposite to the sensor chip A surface); the second direction X intersects the first direction Y; the gravity module 30 also includes a second gravity unit 302, which includes a second conductive slider 3021, a second cavity 3023 extending along the second direction X, and a second fixed conductive slider 3022; the second conductive slider 3021 is located in the second cavity 3023 and is slidably connected to the second fixed conductive block 3022; the second conductive slider 3021 is used to slide along the second direction X in the second cavity 3023.

[0047] Specifically, the first direction Y and the second direction X can be perpendicular. The first conductive portion 10 and the second conductive portion 20 of the sensor are respectively connected to two surfaces arranged opposite each other along the first direction Y, and the third conductive portion 90 and the fourth conductive portion 100 are respectively connected to two surfaces arranged opposite each other along the second direction X. This enables the detection of the orientation of the two surfaces arranged opposite each other along the first direction, and also enables the detection of the orientation of the two surfaces arranged opposite each other along the second direction. A second cavity 3023 is provided between the third conductive portion 90 and the fourth conductive portion 100, so that when the sensor is flipped, the second conductive slider 3021 can slide within the second cavity 3023.

[0048] Furthermore, since the second conductive slider 3021 has a certain weight, it will slide within the second cavity 3023 under the influence of its own gravity during sensor movement. For example, the two surfaces arranged opposite each other along the second direction can be surface A and surface B of the sensor chip. The third conductive portion 90 is connected to surface A, and the fourth conductive portion 100 is connected to surface B. Since the third conductive portion 90, the fourth conductive portion 100, the second conductive slider 3021, and the second fixed conductive block 3022 are all conductive, when surface B is facing upwards and surface A is facing downwards, the third conductive portion 90, the second conductive slider 3021, and the second fixed conductive block 3022 are electrically connected, allowing the sensor output to output a certain level signal. When surface B is facing downwards and surface A is facing upwards, the fourth conductive portion 100, the second conductive slider 3021, and the second fixed conductive block 3022 are electrically connected, allowing the sensor output to output another level signal. Based on the two different level signals output, the orientation of surface A and surface B can be determined. By setting the first gravity unit 301 and the second gravity unit 302, the orientation of two surfaces arranged opposite each other along the first direction can be detected, and the orientation of two surfaces arranged opposite each other along the second direction can also be detected, thereby improving the detection range of the sensor.

[0049] For example, the first gravity unit can detect the orientation of two surfaces in the earphone that are positioned opposite each other along a first direction, and the second gravity unit can detect the orientation of two surfaces in the earphone that are positioned opposite each other along a second direction. Thus, when a person is wearing the earphone normally, such as while walking or sitting, detecting the orientation of the two surfaces positioned opposite each other along the first direction allows for detection of whether the earphone is worn in the left or right ear, thereby achieving self-adaptation between the left and right earphones. Furthermore, when a person is lying down or prone, detecting the orientation of the two surfaces positioned opposite each other along the second direction allows for detection of whether the earphone is worn in the left or right ear, thereby achieving self-adaptation between the left and right earphones.

[0050] It is understood that the sensor may also include a level output unit electrically connected to the second fixed conductive block 3022, and an output terminal 80 electrically connected to the level output unit 50.

[0051] Optional, Figure 4 An electrical schematic diagram of the fourth type of sensor provided in this embodiment of the present invention is shown below. Figure 1 and Figure 4 As shown, the first conductive slider 3011 includes a first conductive sphere or a first conductive rectangular block.

[0052] Specifically, as one possible implementation method, please refer to [reference]. Figure 1 The first conductive slider 3011 includes a first conductive rectangular block. By setting the shape of the first conductive slider 3011 to a cube, the contact area between the first conductive slider 3011 and the first conductive portion 10, the second conductive portion 20 and the first fixed conductive block 3012 can be increased, which helps to ensure the conductivity effect and thus improve the stability of the sensor.

[0053] As one possible implementation method, please refer to [reference]. Figure 4 The first conductive slider 3011 includes a first conductive sphere. By setting the shape of the first conductive slider 3011 to be a sphere, it is beneficial for the first conductive slider 3011 to slide within the first cavity 3013, thereby improving the detection accuracy of the sensor.

[0054] Optional, continue to refer to Figure 1 The level output unit 50 includes a metal-oxide-semiconductor field-effect transistor. When the first conductive slider 3011 slides in the first cavity 3013, it outputs a level signal to the control terminal of the metal-oxide-semiconductor field-effect transistor, thereby controlling the conduction and turn-off of the metal-oxide-semiconductor field-effect transistor. Thus, the orientation of two surfaces arranged opposite to each other along the first direction can be detected based on the conduction and turn-off of the metal-oxide-semiconductor field-effect transistor.

[0055] For example, the level output unit 50 can also consist 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.

[0056] Optional, continue to refer to Figure 1 Along the second direction X, the first conductive portion 10 and the second conductive portion 20 are both located on one side of the first cavity 3013, and the first fixed conductive block 3012 is located on the other side of the first cavity 3013. The second direction X intersects the first direction Y. The first conductive portion 10 and the second conductive portion 20 both extend along the first direction Y and are both parallel to the extension direction of the first fixed conductive block 3012.

[0057] Specifically, the two conductive portions and the first fixed conductive block 3012 are located on both sides of the first cavity 3013, so that when the first conductive slider 3011 slides in the first cavity 3013, the first conductive slider 3011 can be electrically connected to the first conductive portion 10 and the first fixed conductive block 3012, or the first conductive slider 3011 can be electrically connected to the second conductive portion 20 and the first fixed conductive block 3012.

[0058] Optional, continue to refer to Figure 4 Along the first direction Y, the first conductive portion 10 is located on one side of the first cavity 3013, and the second conductive portion 20 is located on the other side of the first cavity 3013; both the first conductive portion 10 and the second conductive portion 20 extend along the second direction X, and are both perpendicular to the extension direction of the first fixed conductive block 3012; the second direction X intersects with the first direction Y.

[0059] Specifically, along the first direction Y, the first conductive portion 10 and the second conductive portion 20 are located on both sides of the first cavity 3013, which enables the first conductive slider 3011 to be electrically connected to the first conductive portion 10 and the first fixed conductive block 3012, or the first conductive slider 3011 to be electrically connected to the second conductive portion 20 and the first fixed conductive block 3012. On the other hand, it enables diversified design of the sensor.

[0060] In summary, the sensor provided by this embodiment of the present invention, by setting a first conductive slider in a first gravity unit, allows the first conductive slider to slide within a first cavity due to its own gravity during sensor movement. For example, the two surfaces arranged opposite each other along a first direction can be surface A and surface B of the sensor chip. When surface B faces downwards, the first conductive slider slides from surface A to surface B due to gravity, meaning surface B of the sensor chip, the first conductive slider, and the first fixed conductive block are connected, thereby outputting a voltage level signal. When surface A faces downwards, the first conductive slider slides from surface B to surface A due to gravity, meaning surface A of the sensor chip, the first conductive slider, and the first fixed conductive block are connected, thereby outputting a different voltage level signal. Because the voltage levels connected to the first conductive portion and the second conductive portion are different, the voltage level signals output when the first conductive slider slides to the first conductive portion and the second conductive portion are different, thus allowing the orientation of the two oppositely arranged surfaces to be determined based on the voltage level signals.
