The second battery 201, the charging interface 202, the charging terminal 121 and the first battery 120 form a charging loop, so that the electric 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.

As shown in fig. 3, fig. 3 is a schematic structural diagram of the earphone 10 in the earphone assembly 1 shown in fig. 2. The headset 10 includes a headset head 101, a stem 102, an optical sensor 103, and an optical assembly 104.

Specifically, the earphone head 101 and the ear handle 102 may be integrally formed, or may be detachably or non-detachably connected to each other. Optionally, the earphone head 101 and the ear handle 102 are connected by an internal thread. The ear handle 102 is in a hollow cylindrical shape, and the ear handle 102 is used for accommodating the first battery 120, the antenna, the flexible circuit board, and the like. The charging terminal 121 is disposed at an end of the ear stem 102 away from the earphone head 101. Optionally, the charging terminal 121 is a convex metal shell, and the charging terminal 121 is hermetically connected to an end of the ear stem 102 away from the earphone head 101.

Referring to fig. 3 and 4, the earphone head 101 includes a first shell 110 and a second shell 112 that are matched with each other, and the first shell 110 and the second shell 112 are designed to fit the ear canal of a human body. Optionally, the first casing 110 and the second casing 112 are bonded together. The first housing 110 and the second housing 112 enclose a receiving cavity and a sound outlet hole 111, which are communicated with each other, and the optical sensor 103 and the optical element 104 are located in the receiving cavity. The sound outlet hole 111 is for facing into the ear canal of a human body.

For convenience of description, the following embodiments define a direction perpendicular to the plane of the sound emitting hole 111 as a first direction, which is referred to as an X-axis direction. The extending direction of the ear handle 102 is defined as a second direction, which is denoted as the Y-axis direction, and the second direction is perpendicular to the first direction. The direction perpendicular to the XY plane is defined as the third direction, denoted as the Z-axis direction. In fig. 4, the directions indicated by arrows are the X-axis forward direction, the Y-axis forward direction, and the Z-axis forward direction, respectively.

Referring to fig. 5 to 7, the earphone head 101 has a first light through hole 113 and a second light through hole 114 disposed opposite to each other. Optionally, the first light passing hole 113 is disposed on the first casing 110, and the second light passing hole 114 is disposed on the second casing 112. The first light through hole 113 and the second light through hole 114 are respectively located at two sides of the sound outlet hole 111. In other words, the first light passing hole 113 and the second light passing hole 114 are disposed opposite to each other in the Z-axis direction, or the first light passing hole 113 and the second light passing hole 114 are disposed opposite to each other in the Y-axis direction.

In one embodiment, as shown in fig. 7, the first light passing hole 113 and the second light passing hole 114 are disposed opposite to each other along the Z-axis direction, and when the user wears the earphone 10, the first housing 110 contacts the concha and the second housing 112 contacts the tragus. The light emitted from the optical sensor 103 is partially emitted through the optical component 104 and the first light-passing hole 113, and the light emitted outside the earphone 10 is blocked by the concha and reflected to the optical sensor 103 through the first light-passing hole 113 and the optical component 104. Another part of the light emitted by the optical sensor 103 is emitted through the optical component 104 and the second light through hole 114, and the light emitted outside the earphone 10 is blocked by the tragus and is reflected to the optical sensor 103 through the second light through hole 114 and the optical component 104.

Referring to fig. 5 and 6, the first light passing hole 113 may be a through hole of the first housing 110. The second light passing hole 114 may be a through hole of the second housing 112. A first light-transmitting mirror 140 may be disposed in the first light-transmitting hole 113, a second light-transmitting mirror 141 may be disposed in the second light-transmitting hole 114, and the first light-transmitting mirror 140 and the second light-transmitting mirror 141 are used to block external dust from entering the earphone head 101. The outer surfaces of the first and second light-transmitting

mirrors

mirrors

140 and 141 are flush with the inner surface of the headphone head 101. Of course, the first light passing hole 113 may also be a transparent area on the first casing 110, and the second light passing hole 114 may also be a transparent area on the second casing 112.

Referring to fig. 7 and 8, an optical sensor 103 is disposed in the earphone head 101 for emitting light. Optionally, the optical sensor 103 is an ambient light sensor, an infrared light sensor, or the like. The optical sensor 103 may be fixed to the inner surface of the earpiece head 101. In one embodiment, the optical sensor 103 is fixed on the inner surface of the earphone head 101 and is disposed near the sound outlet hole 111, and the optical sensor 103 may be located on the side of the sound outlet hole 111 facing the forward direction of the Y-axis, or the optical sensor 103 may be located on the side of the sound outlet hole 111 facing the reverse direction of the Y-axis. The optical sensor 103 is used for emitting light towards the side departing from the sound emitting hole 111, so that the light emitted by the optical sensor 103 is reduced to be emitted through the sound emitting hole 111, and the light utilization rate is improved. The optical sensor 103 includes a light source 130 and a receiver 131. The light source 130 is used to emit light. Alternatively, the Light source 130 may be a Light Emitting Diode (LED). The light source 130 may be configured to emit visible light, infrared light, monochromatic (e.g., green, red, blue) light, and the like. The receiver 131 is used for receiving the light reflected back through the first light passing hole 113 and the second light passing hole 114, respectively.

Referring to fig. 7 and 9, the optical assembly 104 is disposed in the earpiece 101. In one embodiment, the optical assembly 104 is fixed to the inner surface of the earpiece 101, and the optical assembly 104 is partially located between the first light aperture 113 and the optical sensor 103, and another portion of the optical assembly 104 is located between the second light aperture 114 and the optical sensor 103. In another embodiment, the optical element 104 is fixed on the outer surface of the optical sensor 103, a portion of the optical element 104 is located between the light-emitting side of the optical sensor 103 and the first light-passing hole 113, and another portion of the optical element 104 is located between the light-emitting side of the optical sensor 103 and the second light-passing hole 114.

The optical assembly 104 is configured to emit light rays emitted by the optical sensor 103 toward the first light-passing hole 113 and the second light-passing hole 114, respectively, and to make the light rays reflected back through the first light-passing hole 113 and the second light-passing hole 114 irradiate the optical sensor 103. Optionally, the light emitted by the optical sensor 103 is refracted by the optical component 104 and then emitted toward the first light through hole 113 and the second light through hole 114 respectively; or, the light emitted by the optical sensor 103 is converged by the optical component 104 and then emitted toward the first light through hole 113 and the second light through hole 114 respectively; or, the light emitted by the optical sensor 103 is emitted toward the first light through hole 113 and the second light through hole 114 after being diverged by the optical component 104; or, the light emitted from the optical sensor 103 is reflected by the optical component 104 and then emitted toward the first light-passing hole 113 and the second light-passing hole 114, respectively.

Through set up optical sensor 103 and optical assembly 104 in earphone head 101, the light that optical sensor 103 launched jets out towards first light through hole 113 and the second light through hole 114 of earphone head 101 respectively after optical assembly 104 to can detect the light that reflects back through first light through hole 113 and second light through hole 114 respectively, judge whether first light through hole 113 and second light through hole 114 are sheltered from, in order to realize the multiple spot and detect, improve and wear the rate of accuracy that detects. The optical assembly 104 directs the light emitted from the optical sensor 103, so that the number of the optical sensors 103 can be reduced, the power consumption can be reduced, the cost can be saved, and the position requirement for the optical sensor 103 can be reduced.

In one embodiment, referring to fig. 7 and 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 passing hole 113 and the optical sensor 103. The second convex lens 144 is disposed between the second light passing hole 114 and the optical sensor 103. The first convex lens 143 is configured 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 passing hole 113. The second convex lens 144 is used for receiving the light emitted by the optical sensor 103 and making the light emitted by the optical sensor 103 form a second emergent light 144a to be emitted through the second light passing hole 114.

The outer surface of the first convex lens 143 may include at least one surface of an outer convex shape. Optionally, the incident surface of the first convex lens 143 is convex; alternatively, 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; alternatively, 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.

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, a part of the light emitted from the light source 130 passes through the first convex lens 143 to form a first exit light 143a, and another part passes through the second convex lens 144 to form a second exit light 144a, and at this time, the first exit light 143a passing through the first convex lens 143 can be directed to the first light passing hole 113 to be emitted, and the second exit light 144a passing through the second convex lens 144 can be directed to the first light passing hole 113 to be emitted. In other words, the light emitted from the optical sensor 103 can be emitted through the first light passing hole 113 and the second light passing 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 outward, the light reflected back through the first light passing hole 113 is converged when passing through the first convex lens 143, and the light reflected back through the second light passing hole 114 is converged when passing through the second convex lens 144. In this case, the optical sensor 103 can receive a large amount of light, thereby improving the accuracy of wearing detection.

Optionally, the position of the optical sensor 103 for emitting the point light source 130 is located at the focus of the first convex lens 143, and/or the position of the optical sensor 103 for emitting the point light source 130 is located at the focus of the second convex lens 144. The optical sensor 103 emits the position of the point light source 130, that is, the position of the light source 130 (see fig. 8). In one embodiment, the position where the optical sensor 103 emits the point light source 130 is located at the focal point of the first convex lens 143. According to the convex lens and the reversible principle of light rays, it can be understood that when the light source 130 is located at the focal point of the first convex lens 143, the light rays emitted by the light source 130 partially pass through the first convex lens 143 to form parallel first emergent light rays 143 a. At this time, if the first emergent light beam 143a is parallel, the first light passing hole 113 and the emergent surface of the first convex lens 143 are parallel, so that more or all of the first emergent light beam 143a can be emitted through the first light passing hole 113. In another embodiment, the position where the optical sensor 103 emits the point light source 130 is located at the focal point of the second convex lens 144. When the light source 130 is located at the focal point of the second convex lens 144, a portion of the light emitted from the light source 130 passes through the second convex lens 144 to form a parallel second emergent light 144 a. At this time, the second emergent ray 144a is a parallel ray, and the second emergent ray 144a can be emitted through the second light passing hole 114 more or all by making the second light passing hole 114 parallel to the emergent surface of the second convex lens 144.

In other words, the light utilization rate can be improved by positioning the position of the light source 130 at the emitting point of the optical sensor 103 at the focal point of the first convex lens 143 or positioning the light source 130 at the emitting point of the optical sensor 103 at the focal point of the second convex lens 144, and the first outgoing light 143a and the second outgoing light 144a are prevented from being incident on the inner surface of the earphone head 101, and are received by the receiver 131 after being reflected, which affects 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 passing hole 113, and the position of the second convex lens 144 can be determined by the position of the second light passing hole 114, thereby facilitating the installation of the first convex lens 143 and the second convex lens 144.

In addition, if the position of the light source 130 at the emitting point of the optical sensor 103 is located at the focal point of the first convex lens 143, according to the reversible principle of light rays, it can be understood that the light rays reflected back through the first light passing 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 the light rays can be improved. If the position of the light source 130 at the emitting point of the optical sensor 103 is located at the focus of the second convex lens 144, according to the reversible principle of light, it can be understood that the light reflected back through the second light passing hole 114 can be converged 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 for receiving light can be improved.

In yet another embodiment, the focal point of the first convex lens 143 coincides with the focal point of the second convex lens 144. The position where the optical sensor 103 emits the point light source 130 is located at the focal point of the first convex lens 143 and the focal point of the second convex lens 144. The first emergent ray 143a is a parallel ray. The second outgoing light ray 144a is a parallel light ray. In the present embodiment, the first convex lens 143 is positioned with respect to the first light passing hole 113 so that a large amount or all of the first outgoing light beams 143a can be emitted through the first light passing hole 113, and the second convex lens 144 is positioned with respect to the second light passing hole 114 so that a large amount or all of the second outgoing light beams 144a can be emitted through the second light passing 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.

Optionally, referring to fig. 7 and 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, and the like. The first prism 146 is disposed between the first light passing 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 outgoing light 143a, and the exit surface of the first prism 146 faces the first light passing hole 113 to enable the first outgoing light 143a to exit linearly through the first light passing hole 113. The second prism 147 is disposed between the second light passing 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 outgoing light 144a, and the outgoing surface of the second prism 147 faces the second light passing hole 114 to enable the second outgoing light 144a to be emitted linearly through the second light passing hole 114. In one embodiment, first prism 146 is fixedly attached to the inner surface of the earpiece head 101 or to the first light-transmissive mirror 140 (see fig. 5). The exit surface of the first prism 146 is attached to the inner surface of the first transparent mirror 140, so that all the light rays emitted through the exit surface of the first prism 146 can be emitted through the first transparent mirror 140. The second prism 147 is fixedly coupled to the inner surface of the earphone head 101 or fixedly coupled to the second light-transmitting mirror 141 (see fig. 6). The exit surface of the second prism 147 is attached to the inner surface of the second transparent mirror 141, so that all the light emitted through the exit surface of the second prism 147 can be emitted through the second transparent mirror 141.

In this embodiment, by disposing the first prism 146 at the position of the first light passing hole 113, disposing the second prism 147 at the position of the second light passing hole 114, the incident surface of the first prism 146 faces the emergent surface of the first convex lens 143, the emergent surface of the first prism 146 faces the first light passing hole 113, the incident surface of the second prism 147 faces the second convex lens 144, and the emergent surface of the second prism 147 faces the second light passing hole 114, it is possible to realize that more or all of the first emergent light beams 143a are emitted through the first light passing hole 113 when the emergent surface of the first convex lens 143 is not parallel to the first light passing hole 113, and that more or all of the second emergent light beams 144a are emitted through the second light passing hole 114 when the emergent surface of the second convex lens 144 is not parallel to the second light passing hole 114.

In other words, providing the first prism 146 may reduce the restriction on the position of the first convex lens 143, and providing the second prism 147 may reduce the restriction on the position of the second convex lens 144. When the included angle between the first outgoing light beam 143a emitted by the first convex lens 143 and the first light passing hole 113 is an acute angle, the first outgoing light beam 143a can still be emitted more or all through the first light passing hole 113 after being refracted and reflected in the first prism 146. When the included angle between the second outgoing light 144a emitted by the second convex lens 144 and the second light passing hole 114 is an acute angle, the second outgoing light 144a can still be emitted more or all through the second light passing 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 the present embodiment reduces the requirement for the arrangement position of the optical sensor 103, the first convex lens 143, and the second convex lens 144 in the earphone head 101, and can reduce the difficulty of stacking the structure and improve the assembly efficiency in the case that the inner space of the earphone head 101 is narrow and a plurality of parts need to be stacked.

Further, referring to fig. 7 and 12, the first prism 146 and the second prism 147 are all 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. One of the edges in the cross-section of the first prism 146 is an entrance surface of the first prism 146, and the other edge in the cross-section of the first prism 146 is an exit surface of the first prism 146. The plane of the hypotenuse in the cross-section of the first prism 146 is a first bevel. The first outgoing light beam 143a is perpendicularly incident on the incident surface of the first prism 146, and then is incident on the first inclined surface along the original direction, and since the incident angle (45 °) is greater than the critical angle (42 °) of the light beam entering the air from the glass, the first outgoing light beam 143a is totally reflected on the first inclined surface and is emitted in the direction perpendicular to the outgoing surface of the first prism 146. One of the right-angled sides of the cross-section of the second prism 147 is the entrance surface of the second prism 147, and the other of the right-angled sides of the cross-section of the second prism 147 is the exit surface of the second prism 147. The plane of the hypotenuse in the cross section of the second prism 147 is the second inclined plane. The second outgoing light 144a is perpendicularly incident on the incident surface of the second prism 147, and then is incident on the second inclined surface along the original direction, because the incident angle (45 °) is greater than the critical angle (42 °) of the light entering the air from the glass, the second outgoing light 144a is totally reflected on the second inclined surface and is emitted in the direction perpendicular to the outgoing surface of the second prism 147. Based on the above principle, the first outgoing light beam 143a is perpendicularly incident on the incident surface of the first prism 146, and the second outgoing light beam 144a is perpendicularly incident on the incident surface of the second prism 147, so that the first outgoing light beam 143a is totally reflected and then is totally emitted through the first light passing hole 113, and the second outgoing light beam 144a is totally reflected and then is totally emitted through the second light passing hole 114. In this embodiment, the first outgoing light beam 143a and the second outgoing light beam 144a can be prevented from being refracted at the inner surface of the headphone head 101 and being diffusely reflected to the receiver 131 of the optical sensor 103 by the inner surface of the headphone 10, thereby causing erroneous determination of wearing detection.

In the embodiment of the application, the first light through hole 113 and the second light through hole 114 are arranged on the earphone head 101, and light emitted by the optical sensor 103 is emitted out of the first light through hole 113 and the second light through hole 114 after passing through the optical component 104. Whether the first light passing hole 113 and the second light passing hole 114 are blocked is determined by detecting the light reflected back through the first light passing hole 113 and the second light passing hole 114, respectively. When the first light through hole 113 and the second light through hole 114 are both blocked, it is determined that the earphone 10 is in a wearing state. When the first light-passing hole 113 and the second light-passing hole 114 are not blocked, or at least one of the first light-passing hole 113 and the second light-passing hole 114 is not blocked, it is determined that the earphone 10 is not worn. Thus, detection of multiple points is performed, and the misrecognition rate is reduced. In addition, the embodiment of the application can realize the detection of two points only by arranging a single optical sensor 103, and can reduce power consumption and cost and reduce the difficulty of structure stacking compared with a detection scheme for realizing multiple points by arranging a plurality of optical sensors 103.

Further, as shown in fig. 13, the headset 10 may further include a controller 105. The controller 105 is disposed within the earpiece 101 or the ear stem 102 and is electrically connected to the optical sensor 103. The embodiment of the present application is described with the controller 105 disposed in the ear 102. The controller 105 is used for controlling the working state of the earphone 10 according to the shielding condition of the first light through hole 113 and the second light through hole 114. In an embodiment, when the first light-passing hole 113 and the second light-passing hole 114 are both blocked, it is determined that the earphone 10 is in the wearing state, and the controller 105 controls the earphone 10 to establish a wireless communication connection with the electronic device 2 (see fig. 1) and start playing music. When the first light-passing hole 113 and the second light-passing hole 114 are not blocked, or at least one of the first light-passing hole 113 and the second light-passing hole 114 is not blocked, it is determined that the earphone 10 is not worn, and 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 the earphone 10 is determined to be worn, the controller 105 controls sound to be output through the sound output hole 111 of the earphone 10. When it is determined that the headphone 10 is in the unworn state, the controller 105 controls sound to be emitted through the electronic apparatus 2. Of course, in other embodiments, the controller 105 may also control the headset 10 to automatically enter a pass-through mode when removed, to respond to user interaction only when worn, and the like.

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