[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] Please see Figure 1 and Figure 2This application provides an embodiment of an earphone 100, which includes a sound-emitting component 10, a wearing component 20, a photoelectric sensor 30, and a capacitive sensor 40. The sound-emitting component 10 is connected to the wearing component 20. The photoelectric sensor 30 can be disposed on the sound-emitting component 10 and is used to detect whether the sound-emitting component 10 is in a wearing state. The capacitive sensor 40 is disposed on the wearing component 20 and is used to detect whether the wearing component 20 is in a contact state. When both the photoelectric sensor 30 and the capacitive sensor 40 are triggered, the sound-emitting component 10 can be controlled to work.

[0036] Optionally, both the photoelectric sensor 30 and the capacitive sensor 40 are electrically connected to the sound-generating component 10. When the earphone 100 is worn in the ear, the sound-generating component 10 is located in the ear canal, and the photoelectric sensor 30 is also located in the ear canal. When the photoelectric sensor 30 is blocked by the ear, it can detect that the sound-generating component 10 is in a wearing state. When the earphone 100 is not worn in the ear, for example, when the earphone 100 is placed on a table, the photoelectric sensor 30 is not blocked, and the photoelectric sensor 30 detects that the sound-generating component 10 is not in a wearing state.

[0037] When the earphone 100 is worn on the ear, the wearing part 20 can hang on the ear, and the capacitive sensor 40 can come into contact with the human skin. After the capacitive sensor 40 comes into contact with the human skin, it can detect that the wearing part 20 is in the wearing state. When the earphone 100 is not worn on the ear, the wearing part 20 is not in contact with any external object, or in other words, the wearing part 20 is not squeezed. At this time, the capacitive sensor 40 is also not squeezed, and the capacitive sensor 40 detects that the wearing part 20 is not in the contact state. When the photoelectric sensor 30 detects that the sound-emitting part 10 is in the wearing state, and the capacitive sensor 40 detects that the wearing part 20 is in the contact state, the sound-emitting part 10 can be controlled to work.

[0038] Therefore, the sound-generating component 10 only starts working when both the photoelectric sensor 30 and the capacitive sensor 40 are triggered. If only one of the photoelectric sensor 30 and the capacitive sensor 40 is triggered, neither can control the sound-generating component 10 to work. This can prevent the headphones 100 from being accidentally activated, prevent the battery power of the headphones 100 from being consumed, and increase the standby time of the headphones 100.

[0039] Please see Figure 2In some embodiments, a main control board 11 is provided inside the sound-generating component 10. The photoelectric sensor 30 and the capacitive sensor 40 are both electrically connected to the main control board 11. The main control board 11 is used to control the sound-generating component 10 to work when the photoelectric sensor 30 detects that the sound-generating component 10 is in a wearing state and the capacitive sensor 40 detects that the wearing component 20 is in a contact state. The main control board 11 is also used to control the sound-generating component 10 to turn off when the photoelectric sensor 30 detects that the sound-generating component 10 is not in a wearing state and / or when the capacitive sensor 40 detects that the wearing component 20 is not in a contact state.

[0040] Optionally, the sound-generating component 10 has a main control board 11 inside. The photoelectric sensor 30 can be electrically connected to the main control board 11, and the capacitive sensor 40 can be electrically connected to the main control board 11 through a connecting wire harness. When the earphone 100 is worn on the ear, the photoelectric sensor 30 can generate a wearing signal after being blocked. The wearing signal can be transmitted to the main control board 11. The capacitive sensor 40 can generate a contact signal after contacting human skin. The contact signal can also be transmitted to the main control board 11. The main control board 11 can only control the sound-generating component 10 to start working when it receives both the wearing signal and the contact signal at the same time.

[0041] When the photoelectric sensor 30 is blocked and sends a wearing signal to the main control board 11, but the capacitive sensor 40 is not in contact with other objects and does not send a contact signal to the main control board 11, the main control board 11 can control the sound-generating component 10 to stop working. When the photoelectric sensor 30 is not blocked and does not send a wearing signal to the main control board 11, but the capacitive sensor 40 is in contact with other objects and sends a contact signal to the main control board 11, the main control board 11 still controls the sound-generating component 10 to stop working. When neither the photoelectric sensor 30 nor the capacitive sensor 40 sends a contact signal to the main control board 11, the main control board 11 still controls the sound-generating component 10 to stop working. Therefore, as long as the headphones 100 are not worn on the ears, the control board can control the headphones 100 to stop working. More specifically, when the headphones 100 are not worn on the user's ears, it can prevent the consumption of the headphone 100's battery power and further increase the standby time of the headphones 100.

[0042] It is understandable that the sound-generating component 10 may also have two main control boards 11 inside. The photoelectric sensor 30 is electrically connected to one of the two main control boards 11, and the capacitive sensor 40 is electrically connected to the other of the two main control boards 11. The two main control boards 11 jointly control the opening and closing of the sound-generating component 10. The two main control boards 11 can be set separately, which can facilitate the arrangement of the wiring harness inside the headphone 100.

[0043] Please see Figure 1 and Figure 2In some embodiments, the sound-generating component 10 may include a housing 12, the housing 12 having a through hole 121, and a photoelectric sensor 30 may be disposed inside the housing 12, with the light-receiving surface of the photoelectric sensor 30 facing the through hole 121.

[0044] Optionally, the housing 12 is a protective structure for the sound-generating component 10. The housing 12 is used to protect the internal components of the sound-generating component 10 and prevent the components from being damaged by the external environment. When the earphone 100 is bumped, the photoelectric sensor 30 is disposed inside the housing 12 and can prevent the photoelectric sensor 30 from being damaged.

[0045] The through hole 121 allows external light to enter the interior of the housing 12. The light-receiving surface of the photoelectric sensor 30 faces the through hole 121, enabling the photoelectric sensor 30 to accurately receive the light or light signal entering through the through hole 121, which facilitates the photoelectric sensor 30 in detecting the wearing status of the sound-emitting component 10.

[0046] Preferably, the area of ​​the through hole 121 is larger than the light-receiving surface of the photoelectric sensor 30, so that the photoelectric sensor 30 can receive enough light, thereby improving the sensitivity and response speed of the photoelectric sensor 30.

[0047] Please see Figure 1 and Figure 2 In some embodiments, the sound-generating component 10 may include a light-transmitting sheet 13 disposed at the through hole 121 to seal the through hole 121.

[0048] Optionally, the outer contour shape of the light-transmitting sheet 13 can be the same as the contour shape of the through hole 121, and the outer contour size of the light-transmitting sheet 13 can be adapted to the size of the through hole 121, so that the light-transmitting sheet 13 can be disposed in the through hole 121, the light-transmitting sheet 13 can allow external light to enter the interior of the housing 12, and the light-transmitting sheet 13 can seal the through hole 121 to prevent dust, dirt or other debris from entering the interior of the housing 12.

[0049] Preferably, a sealing ring can be fitted on the outer periphery of the light-transmitting sheet 13. The sealing ring is located between the light-transmitting sheet 13 and the through hole 121. The sealing ring can seal the gap between the light-transmitting sheet 13 and the through hole 121, increase the sealing effect of the through hole 121, and also make the light-transmitting sheet 13 more stable to be installed.

[0050] In some embodiments, the light-transmitting sheet 13 can be a filter. The light-transmitting sheet 13 can not only allow light to pass through, but also filter or selectively absorb certain wavelengths of light. Thus, the light-transmitting sheet 13 can only allow the light received by the photoelectric sensor 30 to pass through, while absorbing or reflecting other colors of light, which can further improve the sensitivity and response speed of the photoelectric sensor 30.

[0051] Specifically, when the photoelectric sensor 30 can receive yellow light, the filter is designed to be yellow. After being filtered by the filter, only yellow light (or light in a wavelength range close to yellow) can penetrate the filter and enter the housing 12, which facilitates the photoelectric sensor 30 in receiving light signals and improves the sensitivity and response speed of the photoelectric sensor 30.

[0052] Please see Figure 1 and Figure 2 In some embodiments, the housing 12 is provided with a sound outlet 122, which is located on the same side of the housing 12 as the through hole 121.

[0053] Optionally, the housing 12 may have a sound-emitting surface, on which a sound-emitting hole 122 and a through hole 121 are provided. When the earphone 100 is worn on the ear, the sound-emitting surface may face the ear, and the sound-emitting hole 122 may face the ear canal opening, while the through hole 121 may also face the ear. Thus, the light-receiving surface of the photoelectric sensor 30 may face the ear, which facilitates the photoelectric sensor 30 in detecting the wearing status of the sound-emitting component 10.

[0054] It should be understood that as long as the earphone 100 is worn correctly in the ear, the sound outlet 122 will definitely face the ear canal opening. Setting the through hole 121 and the sound outlet 122 on the same side of the housing 12 can improve the detection accuracy of the photoelectric sensor 30.

[0055] Please see Figures 1 to 3 In some embodiments, the wearable component 20 includes a soft housing 221, a capacitive sensor 40 disposed within the soft housing 221, and the capacitive sensor 40 contacts the inner sidewall of the soft housing 221.

[0056] Optionally, the soft shell 221 serves as the external structure of the wearing component 20, protecting it. The capacitive sensor 40 is housed inside the soft shell 221, preventing damage. Furthermore, the soft shell 221 is elastic, and the capacitive sensor 40 contacts the inner wall of the soft shell 221. When the wearing component 20 is suspended in the ear, the pressure on the soft shell 221 is transmitted to the capacitive sensor 40, enabling it to detect the contact state of the wearing component 20. Therefore, placing the capacitive sensor 40 inside the soft shell 221 protects it without affecting its ability to detect the contact state of the wearing component 20.

[0057] Please see Figures 1 to 3 In some embodiments, the inner wall of the soft housing 221 is provided with a mounting groove 2211, and the capacitive sensor 40 is disposed in the mounting groove 2211.

[0058] Optionally, the mounting slot 2211 can form a space for accommodating the capacitive sensor 40, which can increase the space utilization within the soft housing 221. The mounting slot 2211 can also restrict the movement of the capacitive sensor 40, accurately positioning the capacitive sensor 40 and the soft housing 221. When the earphone 100 is moved, it can prevent relative movement between the capacitive sensor 40 and the soft housing 221, ensuring that the detection area of ​​the capacitive sensor 40 does not change, thereby improving the detection accuracy of the capacitive sensor 40. In addition, the mounting slot 2211 facilitates the installation of the capacitive sensor 40 and also facilitates the transfer of the compressive force on the soft housing 221 to the capacitive sensor 40, thereby increasing the sensitivity of the capacitive sensor 40.

[0059] Please see Figures 1 to 3 In some embodiments, the capacitive sensor 40 can be extended circumferentially along the soft housing 221, and the sensing area of ​​the capacitive sensor 40 is smaller than the circumferential surface area of ​​the soft housing 221.

[0060] Optionally, the mounting groove 2211 can be extended circumferentially along the soft housing 221. The capacitive sensor 40 is disposed in the mounting groove 2211, which can increase the contact area between the capacitive sensor 40 and the soft housing 221, thereby increasing the sensing area of ​​the capacitive sensor 40 and further increasing the sensitivity of the capacitive sensor 40.

[0061] However, the sensing area of ​​the capacitive sensor 40 is smaller than the peripheral surface area of ​​the soft housing 221. This is because when the wearing component 20 is suspended on the ear, only the side of the soft housing 221 facing the ear is in contact with the human skin, while the side of the soft housing 221 facing away from the ear is not in contact with the human skin. Therefore, the capacitive sensor 40 only needs to be located on the side of the soft housing 221 facing the ear, which can reduce the size of the capacitive sensor 40, save costs, and also reduce the risk of false triggering.

[0062] Please see Figure 1 In some embodiments, the wearable component 20 may include a connecting bridge 21 and a battery compartment 22, one end of the connecting bridge 21 being connected to the sound-generating component 10 and the other end of the connecting bridge 21 being connected to the battery compartment 22, wherein at least one of the connecting bridge 21 and the battery compartment 22 is provided with a capacitive sensor 40.

[0063] Optionally, the battery compartment 22 contains a battery, the connecting bridge 21 can connect the battery compartment 22 and the sound-generating component 10, and the connecting bridge 21 contains a connecting harness, one end of the connecting harness is electrically connected to the battery, and the other end of the connecting harness is electrically connected to the sound-generating component 10, so that the battery can supply power to the sound-generating component 10.

[0064] Optionally, the battery compartment 22 may be equipped with a capacitive sensor 40. When the earphone 100 is worn on the ear, the battery compartment 22 is sandwiched between the earlobe and the cheek, so that the capacitive sensor 40 can be squeezed, thereby detecting that the battery compartment 22 is in contact.

[0065] Similarly, a capacitive sensor 40 can be provided on the connecting bridge 21. When the earphone 100 is worn on the ear, the connecting bridge 21 is suspended at the outer ear and sandwiched between the outer ear and the cheek, which can also make the capacitive sensor 40 squeezed, thereby detecting that the battery compartment 22 is in contact.

[0066] In some other embodiments, the capacitive sensor 40 may include a first capacitive sensing element and a second capacitive sensing element. The first capacitive sensing element is disposed in the battery compartment 22, and the second capacitive sensing element is disposed in the connecting bridge 21. When the earphone 100 is worn on the ear, both the first and second capacitive sensing elements are compressed, which can further increase the detection accuracy of the capacitive sensor 40.

[0067] Secondly, embodiments of this application provide an earphone assembly, which may include earphones 100 and a charging case. The charging case is used to house the earphones 100 so as to charge the earphones 100.

[0068] Optionally, the number of earphones 100 may be two, for example, and the charging case may form two connected or disconnected charging spaces, each for accommodating one earphone 100. The beneficial effects of the earphone assembly in this application are the same as those of the earphones 100 in this application, and will not be repeated here.
