[0032] Setting an optical sensor inside the headset to achieve wearing detection mainly includes single-point detection by a single optical sensor and multi-point detection by multiple optical sensors. Single-point detection has low accuracy and is prone to mistakenly detect that something is not worn as being worn. Multi-point detection requires the setting of multiple optical sensors, which increases power consumption, cost, and difficulty in structural stacking. To this end, the present application achieves multi-point detection and improves the accuracy of wearing detection by designing the structure of the headset as little as possible while minimizing the increase in power consumption, cost, and difficulty in structural stacking.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] like Figure 1 As shown, Figure 1 The electronic system 100 is a schematic diagram of a structure of an electronic system 100 provided in an embodiment of the present application. The electronic system 100 includes an earphone assembly 1 and an electronic device 2.

[0035] The electronic device 2 may be a mobile phone, a tablet computer, a notebook computer, a multi-function player, etc. The present application embodiment is described by taking a mobile phone as an example.

[0036] like Figure 2 As shown, Figure 2 for Figure 1 The structure diagram of the earphone assembly 1 in the electronic system 100 is shown. The earphone assembly 1 includes an earphone 10 and a storage box 20.

[0037] Please refer to Figure 1 and Figure 2 The earphone 10 can be an earbud earphone, an in-ear earphone, a semi-in-ear earphone, an ear-hook earphone, a neck earphone, etc. A wireless communication connection is established between the earphone 10 and the electronic device 2. Optionally, the earphone 10 and the electronic device 2 are connected by a true wireless stereo (True Wireless Stereo, TWS) connection or a Bluetooth connection. The embodiment of the present application is described by taking a TWS earphone as an example. A first battery 120 is provided in the earphone 10, and a charging terminal 121 is provided on the outer surface of the earphone 10.

[0038] The storage box 20 is used to store the earphone 10. Optionally, a second battery 201 and a charging interface 202 are provided in the storage box 20, and the second battery 201 and the charging interface 202 are used to charge the first battery 120 when the earphone 10 is placed in the storage box 20. In one embodiment, when the earphone 10 is stored in the storage box 20, the charging terminal 121 on the outer surface of the earphone 10 contacts the charging interface 202 in the storage box 20. The second battery 201, the charging interface 202, the charging terminal 121 and the first battery 120 form a charging circuit, so that the electrical energy on the second battery 201 can be transmitted to the first battery 120, converted into chemical energy, and stored in the first battery 120.

[0039] like Figure 3 As shown, Figure 3 for Figure 2 The structure diagram of the earphone 10 in the earphone assembly 1 is shown. The earphone 10 includes an earphone head 101, an ear handle 102, an optical sensor 103 and an optical component 104.

[0040] Specifically, the earphone head 101 and the ear handle 102 can be integrally formed, or can be connected as a whole in a detachable or non-detachable manner. Optionally, the earphone head 101 and the ear handle 102 are connected by an internal thread. The ear handle 102 is a hollow column, and the ear handle 102 is used to accommodate the first battery 120, an antenna, a flexible circuit board, etc. The charging terminal 121 is provided at one end of the ear handle 102 away from the earphone head 101. Optionally, the charging terminal 121 is a convex metal shell, and the charging terminal 121 is sealed and connected to one end of the ear handle 102 away from the earphone head 101.

[0041] Please refer to Figure 3 and Figure 4 The earphone head 101 includes a first shell 110 and a second shell 112 that cooperate with each other. The first shell 110 and the second shell 112 are designed to fit the structure of the human ear canal. Optionally, the first shell 110 and the second shell 112 are bonded together. The first shell 110 and the second shell 112 are surrounded to form a receiving cavity and a sound outlet 111 that are interconnected. The optical sensor 103 and the optical component 104 are both located in the receiving cavity. The sound outlet 111 is used to face the human ear canal.

[0042] For ease of description in the following embodiments, a direction perpendicular to the surface where the sound outlet 111 is located is defined as a first direction, which is recorded as the X-axis direction. A direction in which the ear handle 102 extends is defined as a second direction, which is recorded as the Y-axis direction, and the second direction is perpendicular to the first direction. A direction perpendicular to the XY plane is defined as a third direction, which is recorded as the Z-axis direction. Figure 4 In the figure, the arrows indicate the positive directions of the X-axis, the Y-axis, and the Z-axis.

[0043] Please refer to Figures 5 to 7 The earphone head 101 has a first light hole 113 and a second light hole 114 that are arranged opposite to each other. Optionally, the first light hole 113 is arranged on the first shell 110, and the second light hole 114 is arranged on the second shell 112. The first light hole 113 and the second light hole 114 are respectively located on both sides of the sound outlet 111. In other words, the first light hole 113 and the second light hole 114 are arranged opposite to each other along the Z-axis direction, or the first light hole 113 and the second light hole 114 are arranged opposite to each other along the Y-axis direction.

[0044] In one embodiment, if Figure 7As shown, the first light hole 113 and the second light hole 114 are arranged opposite to each other along the Z-axis direction. When the user wears the earphone 10, the first shell 110 contacts the concha, and the second shell 112 contacts the tragus. Part of the light emitted by the optical sensor 103 is emitted through the optical component 104 and the first light hole 113. The light emitted from the outside of the earphone 10 is blocked by the concha, reflected through the first light hole 113 and the optical component 104 to the optical sensor 103. Another part of the light emitted by the optical sensor 103 is emitted through the optical component 104 and the second light hole 114. The light emitted from the outside of the earphone 10 is blocked by the tragus, reflected through the second light hole 114 and the optical component 104 to the optical sensor 103.

[0045] Please refer to Figure 5 and Figure 6 , the first light-through hole 113 may be a through hole of the first shell 110. The second light-through hole 114 may be a through hole of the second shell 112. A first light-transmitting mirror 140 may be disposed in the first light-through hole 113, and a second light-transmitting mirror 141 may be disposed in the second light-through hole 114. The first light-transmitting mirror 140 and the second light-transmitting mirror 141 are used to prevent external dust from entering the earphone head 101. The outer surface of the first light-transmitting mirror 140 and the outer surface of the second light-transmitting mirror 141 are flush with the outer surface of the earphone head 101. The inner surface of the first light-transmitting mirror 140 and the inner surface of the second light-transmitting mirror 141 are flush with the inner surface of the earphone head 101. Of course, the first light-through hole 113 may also be a transparent area on the first shell 110, and the second light-transmitting hole 114 may also be a transparent area on the second shell 112.

[0046] Please refer to Figure 7 and Figure 8 , the optical sensor 103 is arranged in the earphone head 101 and is used to emit light. Optionally, the optical sensor 103 is an ambient light sensor, an infrared light sensor, etc. The optical sensor 103 can be fixed to the inner surface of the earphone head 101. In one embodiment, the optical sensor 103 is fixed to the inner surface of the earphone head 101 and is arranged close to the sound outlet 111. The optical sensor 103 can be located on the side of the sound outlet 111 facing the positive direction of the Y axis, or the optical sensor 103 can be located on the side of the sound outlet 111 facing the opposite direction of the Y axis. The optical sensor 103 is used to emit light toward the side away from the sound outlet 111 to reduce the light emitted by the optical sensor 103 from being emitted through the sound outlet 111 and improve the utilization rate of light. The optical sensor 103 includes a light source 130 and a receiver 131. The light source 130 is used to emit light. Optionally, the light source 130 can be a light emitting diode (LED). The light source 130 may be used to emit visible light, infrared light, monochromatic (eg, green, red, blue) light, etc. The receiver 131 is used to receive the light reflected from the first light hole 113 and the second light hole 114 .

[0047] Please refer to Figure 7 and Fig. 9 , the optical component 104 is disposed in the earphone head 101. In one embodiment, the optical component 104 is fixed to the inner surface of the earphone head 101, a portion of the optical component 104 is located between the first light through hole 113 and the optical sensor 103, and another portion of the optical component 104 is located between the second light through hole 114 and the optical sensor 103. In another embodiment, the optical component 104 is fixed to the outer surface of the optical sensor 103, a portion of the optical component 104 is located between the light exit side of the optical sensor 103 and the first light through hole 113, and another portion of the optical component 104 is located between the light exit side of the optical sensor 103 and the second light through hole 114.

[0048] The optical component 104 is used to direct the light emitted by the optical sensor 103 toward the first light hole 113 and the second light hole 114, respectively, and to direct the light reflected by the first light hole 113 and the second light hole 114 toward the optical sensor 103. Optionally, the light emitted by the optical sensor 103 is refracted by the optical component 104 and then directed toward the first light hole 113 and the second light hole 114, respectively; or, the light emitted by the optical sensor 103 is converged by the optical component 104 and then directed toward the first light hole 113 and the second light hole 114, respectively; or, the light emitted by the optical sensor 103 is diverged by the optical component 104 and then directed toward the first light hole 113 and the second light hole 114, respectively; or, the light emitted by the optical sensor 103 is reflected by the optical component 104 and then directed toward the first light hole 113 and the second light hole 114, respectively.

[0049] By setting an optical sensor 103 and an optical component 104 in the earphone head 101, the light emitted by the optical sensor 103 passes through the optical component 104 and then is emitted toward the first light hole 113 and the second light hole 114 of the earphone head 101, respectively, so that the light reflected back from the first light hole 113 and the second light hole 114 can be detected respectively, and it is determined whether the first light hole 113 and the second light hole 114 are blocked, so as to achieve multi-point detection and improve the accuracy of wearing detection. The optical component 104 directs the light emitted by the optical sensor 103, which can reduce the number of optical sensors 103 to be set accordingly, reduce power loss, save costs, and in addition, the position requirements for the optical sensor 103 are also reduced.

[0050] In one embodiment, please refer to Figure 7 and Fig.10, the optical assembly 104 includes a first convex lens 143 and a second convex lens 144. The first convex lens 143 is disposed between the first light through hole 113 and the optical sensor 103. The second convex lens 144 is disposed between the second light through hole 114 and the optical sensor 103. The first convex lens 143 is used to receive the light emitted by the optical sensor 103 and make the light emitted by the optical sensor 103 form a first outgoing light 143a to be emitted through the first light through hole 113. The second convex lens 144 is used to receive the light emitted by the optical sensor 103 and make the light emitted by the optical sensor 103 form a second outgoing light 144a to be emitted through the second light through hole 114.

[0051] The outer surface of the first convex lens 143 may include at least one convex surface. Optionally, the incident surface of the first convex lens 143 is convex; or, the exit surface of the first convex lens 143 is convex; or, the incident surface of the first convex lens 143 and the exit surface of the first convex lens 143 are both convex. The outer surface of the second convex lens 144 may include at least one convex surface. Optionally, the incident surface of the second convex lens 144 is convex; or, the exit surface of the second convex lens 144 is convex; or, the incident surface of the second convex lens 144 and the exit surface of the second convex lens 144 are both convex.

[0052] It can be understood that when the exit surface of the first convex lens 143 and the exit surface of the second convex lens 144 are convex, part of the light emitted by the light source 130 forms a first exit light 143a when passing through the first convex lens 143, and the other part forms a second exit light 144a when passing through the second convex lens 144. At this time, the first exit light 143a passing through the first convex lens 143 can be aligned with the first light hole 113 and emitted, and the second exit light 144a passing through the second convex lens 144 can be aligned with the first light hole 113 and emitted. In other words, the light emitted by the optical sensor 103 can be emitted through the first light hole 113 and the second light hole 114 as much as possible, thereby reducing light loss. In addition, when the incident surface of the first convex lens 143 and the incident surface of the second convex lens 144 are convex, the light reflected back through the first light hole 113 converges when passing through the first convex lens 143, and the light reflected back through the second light hole 114 converges when passing through the second convex lens 144. At this time, the optical sensor 103 can receive more light, thereby improving the accuracy of wearing detection.

[0053] Optionally, the position where the optical sensor 103 emits the point light source 130 is located at the focus of the first convex lens 143, and / or the position where the optical sensor 103 emits the point light source 130 is located at the focus of the second convex lens 144. Figure 8) position. In one embodiment, the position where the optical sensor 103 emits the point light source 130 is located at the focus of the first convex lens 143. According to the reversible principle of convex lenses and light, it can be understood that when the light source 130 is located at the focus of the first convex lens 143, the light emitted by the light source 130 partially passes through the first convex lens 143 to form a parallel first outgoing light 143a. At this time, the first outgoing light 143a is a parallel light, and the first light hole 113 can be made parallel to the exit surface of the first convex lens 143, so that more or all of the first outgoing light 143a can be emitted through the first light hole 113. In another embodiment, the position where the optical sensor 103 emits the point light source 130 is located at the focus of the second convex lens 144. When the light source 130 is located at the focus of the second convex lens 144, the light emitted by the light source 130 partially passes through the second convex lens 144 to form a parallel second outgoing light 144a. At this time, the second outgoing light 144 a is a parallel light, and the second light hole 114 can be parallel to the exit surface of the second convex lens 144 , so that most or all of the second outgoing light 144 a can be emitted through the second light hole 114 .

[0054] In other words, by locating the position of the optical sensor 103 emitting the point light source 130 at the focus of the first convex lens 143 or the position of the optical sensor 103 emitting the point light source 130 at the focus of the second convex lens 144, the light utilization rate can be improved, and the first outgoing light 143a and the second outgoing light 144a can be prevented from being projected onto the inner surface of the earphone head 101, and then being received by the receiver 131 after being reflected, thereby affecting the accuracy of wearing detection. In addition, the position of the first convex lens 143 can be determined by the position of the first light hole 113, and the position of the second convex lens 144 can be determined by the position of the second light hole 114, thereby facilitating the installation of the first convex lens 143 and the second convex lens 144.

[0055] In addition, if the position of the optical sensor 103 emitting the point light source 130 is located at the focus of the first convex lens 143, then according to the reversible principle of light, it can be understood that the light reflected back through the first light hole 113 can converge at the position of the optical sensor 103 after passing through the first convex lens 143, that is, the efficiency of the optical sensor 103 receiving light can be improved. If the position of the optical sensor 103 emitting the point light source 130 is located at the focus of the second convex lens 144, then according to the reversible principle of light, it can be understood that the light reflected back through the second light hole 114 can converge at the position of the optical sensor 103 after passing through the second convex lens 144, that is, the efficiency of the optical sensor 103 receiving light can be improved.

[0056] In another embodiment, the focus of the first convex lens 143 coincides with the focus of the second convex lens 144. The position of the optical sensor 103 emitting the point light source 130 is located at the focus of the first convex lens 143 and the focus of the second convex lens 144. The first outgoing light 143a is a parallel light. The second outgoing light 144a is a parallel light. In this embodiment, by setting the position of the first convex lens 143 relative to the first light hole 113, more or all of the first outgoing light 143a can be emitted through the first light hole 113, and by setting the position of the second convex lens 144 relative to the second light hole 114, more or all of the second outgoing light 144a can be emitted through the second light hole 114. When the position of the first convex lens 143 and the position of the second convex lens 144 are determined, the fixed position of the optical sensor 103 can be determined by the position of the first convex lens 143 and the position of the second convex lens 144.

[0057] Optional, see Figure 7 and Fig.11 The optical assembly 104 further includes a first prism 146 and a second prism 147. The first prism 146 and the second prism 147 are equilateral triangular prisms, right-angle prisms, etc. The first prism 146 is disposed between the first light-through hole 113 and the first convex lens 143. The incident surface of the first prism 146 faces the exit surface of the first convex lens 143 to receive the first exit light 143a, and the exit surface of the first prism 146 faces the first light-through hole 113 so that the first exit light 143a is emitted straightly through the first light-through hole 113. The second prism 147 is disposed between the second light-through hole 114 and the second convex lens 144. The incident surface of the second prism 147 faces the second convex lens 144 to receive the second exit light 144a, and the exit surface of the second prism 147 faces the second light-through hole 114 so that the second exit light 144a is emitted straightly through the second light-through hole 114. In one embodiment, the first prism 146 is fixedly connected to the inner surface of the earphone head 101, or is fixedly connected to the first light-transmitting mirror 140 (see Figure 5 The exit surface of the first prism 146 is in contact with the inner surface of the first light-transmitting mirror 140, so that all the light emitted from the exit surface of the first prism 146 can be emitted from the first light-transmitting mirror 140. The second prism 147 is fixedly connected to the inner surface of the earphone head 101, or fixedly connected to the second light-transmitting mirror 141 (see Figure 6 The exit surface of the second prism 147 is in contact with the inner surface of the second light-transmitting mirror 141 , so that all the light emitted from the exit surface of the second prism 147 can be emitted from the second light-transmitting mirror 141 .

[0058] In the present embodiment, by disposing the first prism 146 at the position of the first light hole 113 and the second prism 147 at the position of the second light hole 114, the incident surface of the first prism 146 is toward the exit surface of the first convex lens 143, the exit surface of the first prism 146 is toward the first light hole 113, the incident surface of the second prism 147 is toward the second convex lens 144, and the exit surface of the second prism 147 is toward the second light hole 114. When the exit surface of the first convex lens 143 is not parallel to the first light hole 113, it is possible to achieve that most or all of the first exit light 143a is emitted through the first light hole 113, and when the exit surface of the second convex lens 144 is not parallel to the second light hole 114, it is possible to achieve that most or all of the second exit light 144a is emitted through the second light hole 114.

[0059] In other words, the first prism 146 can reduce the restriction on the position of the first convex lens 143, and the second prism 147 can reduce the restriction on the position of the second convex lens 144. When the angle between the first outgoing light 143a emitted from the first convex lens 143 and the first light-through hole 113 is an acute angle, the first outgoing light 143a can still be emitted more or all through the first light-through hole 113 after being refracted and reflected in the first prism 146. When the angle between the second outgoing light 144a emitted from the second convex lens 144 and the second light-through hole 114 is an acute angle, the second outgoing light 144a can still be emitted more or all through the second light-through hole 114 after being refracted and reflected in the second prism 147. It can be understood that the arrangement of the first prism 146 and the second prism 147 in this embodiment reduces the requirements for the arrangement positions of the optical sensor 103, the first convex lens 143 and the second convex lens 144 in the earphone head 101. For situations where the internal space of the earphone head 101 is narrow and multiple components need to be stacked, the difficulty of structural stacking can be reduced and the assembly efficiency can be improved.

[0060] For further information, please refer to Figure 7 and Fig.12, the first prism 146 and the second prism 147 are both total reflection prisms. In other words, the cross section of the first prism 146 and the cross section of the second prism 147 are both isosceles right triangles. The surface where one right-angled side in the cross section of the first prism 146 is located is the incident surface of the first prism 146, and the surface where the other right-angled side in the cross section of the first prism 146 is located is the exit surface of the first prism 146. The surface where the hypotenuse in the cross section of the first prism 146 is located is the first inclined surface. After the first outgoing light 143a is perpendicular to the incident surface of the first prism 146, it is incident on the first inclined surface along the original direction. Since the incident angle (45°) is greater than the critical angle (42°) of the light from the glass into the air, the first outgoing light 143a will be totally reflected on the first inclined surface and emitted in a direction perpendicular to the exit surface of the first prism 146. The surface where one right-angled side in the cross section of the second prism 147 is located is the incident surface of the second prism 147, and the surface where the other right-angled side in the cross section of the second prism 147 is located is the exit surface of the second prism 147. The surface where the hypotenuse in the cross section of the second prism 147 is located is the second inclined surface. After the second outgoing light 144a is perpendicularly incident on the incident surface of the second prism 147, it is incident on the second inclined surface along the original direction. Since the incident angle (45°) is greater than the critical angle (42°) of the light from the glass into the air, the second outgoing light 144a will be totally reflected on the second inclined surface and emitted in a direction perpendicular to the exit surface of the second prism 147. Based on the above principle, by making the first outgoing light 143a perpendicular to the incident surface of the first prism 146 and the second outgoing light 144a perpendicular to the incident surface of the second prism 147, it is possible to achieve that the first outgoing light 143a is totally reflected and then emitted through the first light hole 113, and the second outgoing light 144a is totally reflected and then emitted through the second light hole 114. In this embodiment, it is possible to avoid the first outgoing light 143a and the second outgoing light 144a being refracted on the inner surface of the earphone head 101 and diffusely reflected on the inner surface of the earphone 10 to the receiver 131 of the optical sensor 103, thereby preventing misjudgment of wearing detection.

[0061] In the embodiment of the present application, a first light hole 113 and a second light hole 114 are set on the earphone head 101, and the light emitted by the optical sensor 103 is emitted from the first light hole 113 and the second light hole 114 after passing through the optical component 104. By detecting the light reflected back from the first light hole 113 and the second light hole 114 respectively, it is determined whether the first light hole 113 and the second light hole 114 are blocked. When both the first light hole 113 and the second light hole 114 are blocked, it is determined that the earphone 10 is in a wearing state. When both the first light hole 113 and the second light hole 114 are not blocked, or at least one of the first light hole 113 and the second light hole 114 is not blocked, it is determined that the earphone 10 is not in a wearing state. Thus, multi-point detection is performed to reduce the false recognition rate. In addition, the embodiment of the present application only needs to set up a single optical sensor 103 to achieve two-point detection. Compared with setting up multiple optical sensors 103 to achieve multi-point detection, it can reduce power consumption, cost, and reduce the difficulty of structural stacking.

[0062] Further, such as Fig.13 As shown, the earphone 10 may further include a controller 105. The controller 105 is disposed in the earphone head 101 or the ear handle 102 and is electrically connected to the optical sensor 103. The present application embodiment is described as the controller 105 being disposed in the ear handle 102. The controller 105 is used to control the working state of the earphone 10 according to the blocking conditions of the first light hole 113 and the second light hole 114. In one embodiment, when both the first light hole 113 and the second light hole 114 are blocked, it is determined that the earphone 10 is in a wearing state. At this time, the controller 105 controls the earphone 10 and the electronic device 2 (see Figure 1 ) establishes a wireless communication connection and starts playing music. When both the first light hole 113 and the second light hole 114 are not blocked, or at least one of the first light hole 113 and the second light hole 114 is not blocked, it is determined that the earphone 10 is in an unworn state. At this time, the controller 105 controls the wireless communication connection between the earphone 10 and the electronic device 2 to be disconnected, and stops playing music. In another embodiment, when it is determined that the earphone 10 is in a worn state, the controller 105 controls the sound to be transmitted through the sound outlet 111 on the earphone 10. When it is determined that the earphone 10 is not worn, the controller 105 controls the sound to be transmitted through the electronic device 2. Of course, in other embodiments, the controller 105 can also control the earphone 10 to automatically enter the transparent mode when it is taken off, and respond to user interaction only when it is worn.

[0063] Further, such as Fig.14As shown, the earphone 10 may further include an acceleration sensor 106. The acceleration sensor 106 is used to detect the acceleration direction of the current earphone 10. When the optical sensor 103 detects that both the first light hole 113 and the second light hole 114 are blocked, the controller 105 receives a signal that both the first light hole 113 and the second light hole 114 are blocked, and obtains the acceleration direction of the current earphone 10 detected by the acceleration sensor 106. When the acceleration direction is in the Y-axis direction or close to the Y-axis direction, it is determined that the earphone 10 is in the wearing state.

[0064] like Fig.15 As shown, the following is another earphone 10 structure provided in an embodiment of the present application. The earphone 10 structure is substantially the same as the earphone 10 structure in the above embodiment, except that a third light hole 115 is further provided on the earphone head 101.

In one embodiment, when the earphone 10 is worn in the human ear canal, the connection between the first shell 110 and the second shell 112 is at least partially oriented toward the helix, and the light emitted by the optical sensor 103 is blocked by the helix after being emitted through the third light hole 115, and is reflected back to the position of the optical sensor 103 through the third light hole 115. In this embodiment, a third convex lens may be further provided between the third light hole 115 and the optical sensor 103, a third prism may be provided between the third light hole 115 and the third convex lens, and a third light-transmitting mirror may be further provided in the third light hole 115.
