[0031] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0033] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0034] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of a wireless headset provided in this embodiment.
[0035] The wireless headset mainly includes: an earphone body 100 and an ear hook, the ear hook includes a connecting part 200 and a fixing part 300, the earphone body 100 is connected to the fixing part 300 through the connecting part 200, an earphone mainboard 101 is arranged inside the earphone body 100, a variable capacitor 201 is arranged inside the connecting part 200, and the variable capacitor 201 is electrically connected to the earphone mainboard 101.
[0036] like Figure 1 The wireless headset shown may be an OWS headset, which stands for Open Wearable Stereo. It is an open wearable stereo headset. The headset is fixed to the user's ear mainly through the connection part 200. Therefore, the connection part 200 is generally a C-shaped structure for better wearing. The headset body 100 is placed outside the auricle and will not block the ear canal when worn. The fixing part 300 is used to balance the weight of the headset body 100 and provide a certain clamping arc to better fix the headset. The headset motherboard 101 may be a microcontroller chip for performing corresponding control on the headset.
[0037] The variable capacitor 201 is used to receive a pressure-sensing operation from a user, and the pressure-sensing operation is used to adjust the capacitance of the variable capacitor 201 to generate a capacitance change signal.
[0038] The earphone mainboard 101 is used to detect the capacitance change signal and activate the touch function corresponding to the pressure sensing operation when the capacitance change signal reaches a preset condition.
[0039] With traditional touch-type earphones, users will touch the earphones when wearing and using them, and the probability of accidental touch is high. The wireless earphones provided in this embodiment have a variable capacitor 201 embedded in the connecting part 200. The capacitance of the variable capacitor 201 will change only when the user applies pressure-sensitive operation to the variable capacitor 201, and a slight touch action will not cause its capacitance to change. Moreover, the touch function corresponding to the pressure-sensitive operation will be activated only when the capacitance change signal meets the preset conditions.
[0040] Among them, the preset condition can be that the capacitance change reaches the preset capacitance. For example, the initial capacitance of the variable capacitor 201 is 10. When subjected to a pressure-sensitive operation, if the capacitance becomes 15, the pressure-sensitive operation is determined to be a valid operation. If the capacitance becomes 14, the pressure-sensitive operation is determined to be an invalid operation.
[0041] In this embodiment, a variable capacitor 201 is embedded in the connecting portion 200. The user changes the capacitance of the variable capacitor 201 by applying pressure-sensitive operation to the variable capacitor 201. When the capacitance change of the variable capacitor 201 reaches a preset condition, the touch function corresponding to the pressure-sensitive operation is triggered, thereby greatly reducing the probability of accidental touch during use.
[0042] In one implementation, the variable capacitor 201 includes a first capacitance component and a second capacitance component;
[0043] When no pressure sensing operation from the user is received, the interval between the first capacitor component and the second capacitor component is a first preset distance;
[0044] When a pressure-sensing operation of the user is received, the interval between the first capacitor component and the second capacitor component becomes a second preset distance, and the second preset distance is smaller than the first preset distance.
[0045] like Figure 1 As shown, the connection part 200 is provided with a first capacitor component and a second capacitor component, and the first capacitor component and the second capacitor component are directly opposite to each other. According to the capacitance calculation formula C=∈S / 4πkd, C is capacitance, ∈ is dielectric constant, S is the directly opposite area of the two capacitor components, and d is the distance between the two capacitor components. Figure 1 In the structure shown, the facing area of the first capacitor component and the second capacitor component is fixed, so the capacitance of the variable capacitor 201 has the greatest correlation with the distance d between the two capacitor components.
[0046] Under normal circumstances, the distance between the first capacitor component and the second capacitor component is fixed, that is, d is a first preset distance. When the connecting part 200 is subjected to a pressure-sensitive operation by the user, the pressure-sensitive operation will act on the variable capacitor 201, causing the distance between the first capacitor component and the second capacitor component to decrease, thereby increasing the capacitance of the variable capacitor 201. When the distance between the first capacitor component and the second capacitor component reaches a second preset distance, it can be determined that the pressure-sensitive operation is an operation by the user to activate a touch function of the headset. At this time, the touch function corresponding to the user's pressure-sensitive operation can be stimulated.
[0047] In this embodiment, two capacitor components form a variable capacitor 201, which is embedded in the connecting part 200. When a user applies pressure to the connecting part 200, the distance between the two capacitor components can be changed, thereby changing the capacitance of the variable capacitor 201. When the distance between the two capacitor components reaches a second preset distance, the corresponding touch function is activated, thereby reducing the possibility of accidental touch.
[0048] In one embodiment, the connecting portion 200 is a C-shaped clamp structure, the first capacitor component includes a first memory metal, the second capacitor component includes a second memory metal, the first memory metal and the second memory metal are both arranged in the C-shaped clamp structure, and a flexible circuit board is also arranged in the earphone body 100, and the first memory metal and the second memory metal are both electrically connected to the earphone motherboard 101 through the flexible circuit board.
[0049] In order to facilitate wearing, the overall structure of the wireless headset is usually set to a C-shaped structure. The first capacitor component and the second capacitor component are embedded in the connecting part 200, which will be deformed due to pressure-sensitive operation. In order to maintain the performance of the first capacitor component and the second capacitor component, memory metal can be selected as the capacitor component, so that it deforms when subjected to force and continues to maintain its original shape when not subjected to force, and it fits the C-shaped structure exactly.
[0050] In this embodiment, memory metal is used as a component of the variable capacitor 201, which can not only fit the structure of the earphone, but also ensure the use effect of the variable capacitor 201 and ensure the sensitivity of the wireless earphone.
[0051] In one embodiment, the pressure-sensing operation includes a single press operation, and when the capacitance change signal reaches a preset condition and no other capacitance change signal is detected within a first preset time, the pressure-sensing operation is determined to be the single press operation.
[0052] For example, if a user press operation is detected within 5 seconds and the press operation meets the preset conditions for activating the touch function, the touch function corresponding to the single press operation will be activated, such as the function of adjusting the volume. The user can then adjust the volume of the headphones through other press operations or touch operations.
[0053] In one embodiment, the pressure-sensing operation includes multiple pressing operations. When the capacitance change signal reaches a preset condition and multiple capacitance change signals are detected within the first preset time, the pressure-sensing operation is determined to be the multiple pressing operations.
[0054] For example, if two user press operations are detected within 5 seconds and both press operations meet the preset conditions for activating the touch function, the touch function corresponding to the two press operations will be activated, such as turning on the earphone function. The user can then control the earphone accordingly through other press operations or touch operations.
[0055] If only one pressing operation meets the conditions among multiple pressing operations, it can be determined as a false touch. At this time, the corresponding function will not be activated, and the next pressing operation within 5 seconds will continue to be collected and then judged.
[0056] In one implementation, the pressure-sensing operation includes a continuous pressing operation, and when the capacitance change signal reaches a preset condition and the capacitance change signal lasts for the first preset time, the pressure-sensing operation is determined to be the continuous pressing operation.
[0057] For example, if the user presses the connection portion 200 for 2 seconds, and the capacitance change signal within 2 seconds meets the preset conditions, the function corresponding to the continuous pressing operation can be activated, such as turning off the headset, or other preset functions.
[0058] Reference Figure 2 , Figure 2 A schematic diagram of a flow chart of a wireless headset control method provided in this embodiment.
[0059] The method includes:
[0060] S101 . Receive a user's pressure-sensing operation through the variable capacitor 201 , and adjust the capacitance of the variable capacitor 201 through the pressure-sensing operation to generate a capacitance change signal.
[0061] S102: activating a touch function corresponding to the pressure sensing operation when the capacitance change signal reaches a preset condition.
[0062] Specifically, the variable capacitor 201 of the wireless headset can receive the user's pressure-sensing operation and generate a capacitance change signal under the action of the pressure-sensing operation. When the capacitance change signal meets the preset conditions, the touch function corresponding to the pressure-sensing operation is activated. If the pressure-sensing operation does not meet the preset conditions, the pressure-sensing operation can be determined as an invalid operation, and the corresponding touch function will not be activated, thereby reducing the possibility of accidental touch.
[0063] In one implementation, activating a touch function corresponding to the pressure sensing operation when the capacitance change signal reaches a preset condition includes:
[0064] If the capacitance change signal satisfies a first preset condition, a first touch function is activated, wherein the first preset condition includes that the capacitance change signal is greater than a first threshold value;
[0065] If the capacitance change signal satisfies a second preset condition, a second touch function is activated, wherein the second preset condition includes that the capacitance change signal is greater than a second threshold value and lasts for a preset time.
[0066] For example, the user presses the connection part 200 once, and each press makes the capacitance of the variable capacitor 201 reach the preset capacitance, which can stimulate the corresponding first touch function. At this time, the corresponding touch function can be activated according to the number of presses by the user.
[0067] If the user continues to press the connection part 200 for a preset time, and during the preset time, the capacitance of the variable capacitor 201 is greater than the preset capacitance, then the touch function corresponding to the continuous pressing operation can be executed.
[0068] It can be understood that the method of this embodiment corresponds to the wireless headset control of the above embodiment, and the optional items in the above embodiment are also applicable to this embodiment, so they will not be described repeatedly here.
