Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of wireless headphones, and particularly to headphones with waterproof buttons. Background Art

[0002] With the increase in people's sports and outdoor activities, the use scenarios of wireless headphones are becoming increasingly diverse, and the requirements for their waterproof performance are becoming higher and higher. Currently, a common waterproofing method is to put a soft rubber ring on the buttons of wireless headphones, so that the buttons are tightly connected to the headphone casing through the soft rubber ring, thereby achieving the waterproof purpose.

[0003] However, when using the above method to waterproof wireless headphones, the following technical problems often occur:

[0004] The presence of the soft rubber ring will hinder the pressing and rebound of the button, affecting the user experience. In addition, the soft rubber ring will rub against the shell as the button moves, causing wear over time, thus affecting the durability of the waterproof button.

[0018] Some embodiments of the present disclosure provide a headset with a waterproof button, which can improve the user experience and increase the durability of the waterproof button. Specifically, the reason why the user experience and durability of most headsets with waterproof buttons are poor is that the commonly used waterproof method is to put a soft rubber ring on the button of the wireless headset, so that the button and the headset shell are tightly connected through the soft rubber ring, thereby achieving the purpose of waterproofing. However, the presence of the soft rubber ring will hinder the pressing and rebound of the button, affecting the user experience. In addition, the soft rubber ring will rub against the shell as the button moves, which will cause wear over time, thereby affecting the durability of the waterproof button. Based on this, some embodiments of the present disclosure provide an earphone with a waterproof button. The earphone with a waterproof button includes a button, a sealing gasket, a snap-on piece, a mounting slot, and an earphone body. The earphone body includes a housing; the mounting slot is provided on the housing; the button and the sealing gasket are coaxially assembled; the button and the sealing gasket are both mounted within the mounting slot; a through hole is provided at the bottom of the mounting slot; the through hole is configured to allow the lower end of the button to pass through; the snap-on piece is located within the housing and is configured to snap-on with the lower end; the button is configured to move along the mounting slot; and the sealing gasket is configured to deform as the button moves. Because the sealing gasket is fixedly mounted within the mounting slot, when the button is squeezed, the sealing gasket deforms under force but does not slide relative to the housing, reducing the possibility of wear. Furthermore, the sealing gasket, due to its own elastic force, provides a force to return the button to its original position after deformation, and this force can be fed back to the user through the button. This increases the durability of the waterproof button and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Figure 1 It is a partial cross-sectional view of an earphone with a waterproof button according to some embodiments of the present disclosure. Figure 1 It includes a card plate 1, a sealing gasket 2, a button 3, a limiting groove 4, a mounting groove 5, a shell 6, and a limiting protrusion 7.

[0032] Figure 2 This is a partial cross-sectional view of an earphone with a waterproof button according to some embodiments of the present disclosure from another perspective. Figure 2 It includes a sealing gasket 2, a button 3, a shell 6, a circuit board 8, and an electronic button 9.

[0033] Figure 3Schematic cross-sectional view of the sealing gasket in some embodiments of the present disclosure in an installed state in some embodiments. Figure 3 It includes a sealing gasket 2, a button 3, a mounting groove 5, a housing 6, a button sealing groove 10, an upper sealing protrusion 11, a fixed sealing groove 12, and a lower sealing protrusion 13. Figure 3 For ease of illustration, the upper sealing protrusion 11 and the lower sealing protrusion 13 on the sealing gasket 2 do not completely fit within the key sealing groove 10 and the fixed sealing groove 12. In actual installation, the surface of the upper sealing protrusion 11 fits within the key sealing groove 10, and the lower sealing protrusion 13 fits within the fixed sealing groove 12.

[0034] In some embodiments, the headset with a waterproof button includes a button 3, a sealing gasket 2, a snap-on plate 1, a mounting slot 5, and an earphone body, wherein the earphone body includes a housing 6. The sealing gasket 2 is a hollow, truncated cone or prism-like structure with openings on both the upper and lower surfaces. The sealing gasket 2 can be made of a flexible, waterproof soft plastic material (such as rubber or silicone), without specific limitation. One function of the sealing gasket 2 is to provide waterproofing for the headset. The snap-on plate 1 can be a sheet-like structure with a bend. The snap-on plate 1 is located inside the housing 6 and is configured to snap onto the lower end. The snap-on plate 1 can restrict the button 3 to a certain axial movement range. To achieve this effect, the snap-on plate 1 can be made of one or more of the following materials: metal, plastic, or carbon fiber. The mounting slot 5 is a recessed groove formed in the housing 6. Its primary function is to accommodate the button 3 and the sealing gasket 2 and restrict the button 3 to vertical movement along the axis of the mounting slot 5. The button 3 and the sealing gasket 2 are coaxially assembled in the mounting groove 5. A through hole may be provided at the bottom of the mounting groove 5. The through hole can allow the lower end of the button 3 to pass through. The purpose of this arrangement is to enable the button 3 to pass through the shell 6 so as to transmit the user's operation to the functional structure inside the earphone. The sealing gasket 2 can also support the button 3. When the user presses the button 3, the sealing gasket 2 gives the user a pressing feedback due to its own elasticity, and supports the button 3 to return to its original position before pressing after the user completes the pressing operation. During the user's pressing process, the sealing gasket 2 will deform, and its hollow structural design provides itself with deformation space.

[0035] Alternatively, as Figure 1As shown, the top surface of the sealing gasket 2 can be attached to the button 3, and the bottom surface can be attached to the bottom surface of the mounting groove 5. The contact between the top and bottom surfaces of the sealing gasket 2 tightly connects the button 3 to the mounting groove 5, preventing the sealing gasket 2 from sliding with the movement of the button 3 to a certain extent, ensuring the user's pressing feel.

[0036] Alternatively, as Figure 2 As shown, the earphone body may further include a circuit board 8. The circuit board 8 may be a PCB board. The circuit board 8 is mainly used to integrate the functional components of the earphone body (such as capacitors, inductors, Bluetooth modules, etc.). The circuit board 8 may be located inside the housing 6 to ensure, to a certain extent, that the components on the circuit board 8 are not damaged by external forces. The circuit board 8 may be engaged with the housing 6. This may reduce the possibility of the circuit board 8 shaking inside the housing 6. The circuit board 8 may be engaged with the housing 6 in such a way that two protruding structures with a spacing equal to the thickness of the circuit board 8 are provided inside the housing 6, and the circuit board 8 is engaged between the two protruding structures.

[0037] Optionally, the headset body may include a power supply. The power supply may be a lithium-ion battery, which is not specifically limited herein. The power supply may be electrically connected to the circuit board 8 to supply power to the circuit board 8. The electrical connection may be via a wire. It should be noted that the power supply is not shown in the accompanying drawings.

[0038] Alternatively, as Figure 2 As shown, the earphone body may further include an electronic button 9. The electronic button 9 serves as a communication medium between the button 3 and the circuit board 8. The electronic button 9 may be a pot-type button or a surface-mount button, without specific limitation. The electronic button 9 may be electrically connected to the circuit board 8. The electrical connection may be by welding, without specific limitation. The electronic button 9 may be coaxially mounted with the button 3 to ensure that it is triggered when the button 3 is pressed. During use, when the user presses the button 3, the button 3 in turn presses the electronic button 9, thereby changing the on / off state of the electronic button 9. Because the electronic button 9 is connected to the circuit board 8, it can communicate with the circuit board 8 through changes in on / off state. Pressing the electronic button 9 can transmit and execute commands such as play, pause, change songs, and adjust volume. Furthermore, the electronic button 9 has a certain degree of resilience, which in turn provides a certain degree of resilience to the button 3.

[0039] Alternatively, as Figure 2As shown, the housing 6 is provided with a limiting protrusion 7. The limiting protrusion 7 is located inside the housing 6. The limiting protrusion 7 is a structure that protrudes from the inner wall of the housing 6 into the interior of the housing 6 and is used to limit the position of the clamping piece 1. The clamping piece 1 and the limiting protrusion 7 can be in close contact.

[0040] Alternatively, as Figure 1 As shown, a limit groove 4 may be provided on the button 3. The limit groove 4 may be located on the side of the button 3. The limit groove 4 may be a groove provided on the side of the button 3 and recessed toward the axis of the button 3. There may be at least one limit groove 4, and two are better. The number of the limit grooves 4 is not specifically limited here. The function of the limit groove 4 is to cooperate with the clamping piece 1 to limit the axial movement range of the button 3. In order to play a limiting role, part of the structure of the clamping piece 1 may be extended and inserted into the limit groove 4. Please refer to Figure 1 The thickness of the above-mentioned card plate 1 can be smaller than the height of the above-mentioned limiting groove 4. It should be noted here that the above-mentioned height refers to the length of the above-mentioned limiting groove 4 in the axial direction of the above-mentioned key 3. This is to ensure that when the partial structure of the above-mentioned card plate 1 is inserted into the above-mentioned limiting groove 4, the above-mentioned key 3 can move in the axial direction.

[0041] Alternatively, as Figure 1 As shown, the cross-sectional area of ​​the upper end of the button 3 can be larger than the cross-sectional area of ​​the lower end of the button 3. The purpose of this arrangement is that the larger upper end area can provide a wider pressing area for the fingers, making the operation more comfortable and precise, and reducing the probability of false touches. The user can more easily find the position of the button 3 and apply pressure, especially when operating blindly, and can quickly locate it by touch, thereby improving the convenience of operation. Furthermore, in order to quickly locate the position of the button 3 during blind operation, the top surface of the button 3 can be made higher than the outer surface of the housing 6. In addition, the smaller cross-sectional area of ​​the lower end of the button 3 can reserve installation space for waterproof components (such as sealing gaskets).

[0042] Optionally, the earphones with waterproof buttons may also include a charging compartment. The charging compartment may be a rectangular parallelepiped with a lid. The charging compartment is primarily used to charge the earphones, and thus may include a built-in battery. A structure may also be provided to establish an electrical connection with the earphones.

[0043] Alternatively, as Figure 3As shown, the lower edge of the sealing gasket 2 may be provided with a lower sealing protrusion 13. The lower sealing protrusion 13 may be a protrusion extending outward from the sealing gasket 2. The side of the mounting groove 5 may be provided with a fixed sealing groove 12. The fixed sealing groove 12 may be a groove provided in the side of the mounting groove 5. The lower sealing protrusion 13 and the fixed sealing groove 12 may be of equal height. The depth of the fixed sealing groove 12 may be equal to the extension length of the lower sealing protrusion 13. This arrangement allows the lower sealing protrusion 13 to fit more snugly within the fixed sealing groove 12, thereby securing the lower end surface of the sealing gasket 2 to the bottom surface of the mounting groove 5. The upper edge of the sealing gasket 2 may be provided with an upper sealing protrusion 11. The upper sealing protrusion 11 may be a protrusion extending toward the axis of the sealing gasket 2. The key 3 may be provided with a key sealing groove 10. The key sealing groove 10 may be a groove provided in the side of the key 3. The height of the upper sealing protrusion 11 can be equal to that of the key sealing groove 10. The depth of the key sealing groove 10 can be equal to the extension length of the upper sealing protrusion 11. The purpose of this arrangement is that the upper sealing protrusion 11 can be installed in the key sealing groove 10 more adaptably, so as to achieve the purpose of making the upper end surface of the sealing gasket 2 fit tightly against the key 3. The lower sealing protrusion 13 and the upper sealing protrusion 11 can both be an integral structure with the sealing gasket 2. The reason for designing the lower sealing protrusion 13 and the upper sealing protrusion 11 is that the sealing gasket 2 is made of soft rubber material, which may age over time and its rebound ability will become weaker. Therefore, in order to avoid the problem of the sealing gasket 2 not rebounding after deformation to a certain extent, the lower sealing protrusion 13 and the upper sealing protrusion 11 are provided. The principle is to fix the lower end of the above-mentioned sealing gasket 2 on the bottom surface of the above-mentioned mounting groove 5, and fix the upper end of the above-mentioned sealing gasket 2 on the above-mentioned button 3, so that the rebound force of the above-mentioned electronic button 9 can be transmitted to the above-mentioned sealing gasket 2 through the above-mentioned button 3, providing a certain degree of assistance to the rebound of the above-mentioned sealing gasket 2.

[0044] The above-mentioned optional embodiment, as an inventive feature of the embodiments of the present disclosure, addresses the technical problem that "soft rubber gaskets are prone to not rebounding after prolonged use." This non-rebounding gasket may affect the waterproofing of the headphone buttons, so prevention is necessary. Factors that contribute to the non-rebounding of soft rubber gaskets after prolonged use are as follows: The soft rubber material gradually ages with use, making it prone to non-rebounding. Currently, there is no structure specifically designed to prevent this non-rebounding gasket. Addressing these factors can reduce the likelihood of the gasket not rebounding. To achieve this, the present disclosure also provides a structure that assists in the gasket's rebound. On one hand, the upper and lower ends of the gasket are fixed. On the other hand, after the user presses down and withdraws their finger, the button rebounds due to the rebound force of the electronic key. Furthermore, because the upper and lower ends of the gasket are respectively mounted in a fixed sealing groove and a key sealing groove that moves with the key, this creates a stretching effect on the gasket, thereby reducing the likelihood of the gasket not rebounding.

[0045] Further references Figure 4 , which shows some processes 100 that can be implemented by the processor of some embodiments of the present disclosure.

[0046] Optionally, the earphone body may further include a humidity sensor and a processor. The humidity sensor may be communicatively connected to the processor. The processor may be a single-chip microcomputer, which is not specifically limited here. The communication connection may be via wires or soldering, which is not specifically limited here. The humidity sensor and the processor may both be mounted on the circuit board, and the humidity sensor may be located at one end of the circuit board near the button, so as to better detect whether water has entered the vicinity of the button. The processor is configured to execute the following cyclic steps:

[0047] Step 101: Control the humidity sensor to collect humidity data in the earphone at a preset frequency to obtain initial humidity data.

[0048] The preset frequency may be data collection once per second. The initial humidity data refers to the raw data collected by the humidity sensor without any processing. This data is presented in a sensor-specific format, which may be a two's complement, raw voltage value, or other form. Due to influences such as electrical noise and environmental interference, the raw data may fluctuate and contain errors, making it unsuitable for direct use in determining humidity conditions. Subsequent processing, such as format conversion, is required to obtain a value that accurately reflects the actual humidity.

[0049] In practice, the processor can control the sampling frequency of the humidity sensor through a communication line (such as I2C, SPI, etc.) and a timer interrupt mechanism. For example, data can be collected every 1 second.

[0050] Step 102 pre-processes the initial humidity data to obtain a humidity value. This pre-processing is necessary because the initial humidity data refers to raw, unprocessed data collected by the humidity sensor. It requires format conversion and other processing to accurately reflect the actual humidity. The humidity value represents the humidity of the environment in which the humidity sensor is located.

[0051] In practice, for example, if the humidity sensor outputs an analog voltage signal proportional to humidity, the processor can convert it into a digital value via an analog-to-digital converter (ADC). Assuming the humidity sensor outputs a voltage range of 0-3V, corresponding to a humidity of 0%-100% RH, and the ADC has 12-bit accuracy, the digital output range is 0-4095. If the ADC output value is 2048, the corresponding voltage is 3V × (2048 ÷ 4095) ≈ 1.5V, and the actual humidity is (1.5V ÷ 3V) × 100% = 50% RH.

[0052] Step 103: Compare the humidity value with a preset humidity threshold.

[0053] In practice, the headphone manufacturer can pre-define a humidity threshold in the processor program based on the headphone's waterproof performance, for example, setting the threshold to 65% RH. The comparison step can be implemented using a conditional statement.

[0054] Step 104 : In response to the humidity value being less than the humidity threshold, executing a loop step.

[0055] The above-mentioned loop steps refer to steps 101 to 103. The purpose is to continuously detect the earphones when no water ingress is detected.

[0056] In practice, the processor may determine the magnitude of the humidity value and the humidity threshold through a conditional statement, and in response to the humidity value being less than the humidity threshold, continue to execute steps 101 to 103 through logic control.

[0057] Step 105 : In response to the humidity value being greater than or equal to the humidity threshold, executing emergency processing.

[0058] Among them, the above-mentioned emergency treatment refers to turning off the earphones to reduce the possibility of damage to the internal electronic components of the earphones when they are powered on after water enters the earphones.

[0059] In practice, the processor may determine the size of the humidity value and the humidity threshold through a conditional statement, and in response to the humidity value being greater than or equal to the humidity threshold, control the power management chip to cut off the power supply of the earphone.

[0060] The above steps 101 to 105, as an inventive point of an embodiment of the present disclosure, solve the technical problem of "high scrap rate of earphones after water ingress". The factors that lead to the high scrap rate of earphones after water ingress are as follows: Currently, earphones lack detection and protection measures for water ingress. When water enters the earphones, the earphones are still powered on and running, which may cause a short circuit in the circuit board and damage the electronic components inside the earphones. In addition, most ordinary users do not have the ability to repair electronic components, which leads to the problem of high scrap rate of earphones after water ingress. If the above factors are solved, the effect of reducing the scrap rate of earphones after water ingress can be achieved. In order to achieve this effect, the present disclosure further provides a method for detecting and protecting earphones from water ingress. On the one hand, the humidity inside the earphones is continuously detected by a humidity sensor. On the other hand, when it is detected that the humidity inside the earphones exceeds a threshold, the earphones are powered off to reduce the possibility of damage to the internal components of the earphones to a certain extent. In this way, the effect of reducing the scrap rate of earphones after water ingress can be achieved.

[0061] Further references Figure 5 , which shows some other processes 200 that can be implemented by the processor of some embodiments of the present disclosure.

[0062] Optionally, the earphone body may further include an acceleration sensor. The acceleration sensor may be communicatively connected to the processor. The processor may be further configured to perform the following detection steps:

[0063] Step 201: Collect data from the acceleration sensor at a preset frequency to obtain all-directional acceleration data. The all-directional acceleration data may refer to the acceleration values ​​of the earphone on three axes (X, Y, and Z).

[0064] In practice, the processor may collect data from the acceleration sensor at a preset frequency (eg, 100 Hz) to obtain acceleration data in all directions.

[0065] Step 202: Filter the acceleration data in each direction to obtain filtered data. The filtering is to reduce noise interference. The filtered data refers to the acceleration value on each axis after filtering.

[0066] In practice, the above-mentioned processor can use a sliding average filtering algorithm to smooth the above-mentioned acceleration data in all directions (i.e., the acceleration value on each axis) according to a preset window size (for example, the window size is 10), and obtain the acceleration values ​​on the three axes after filtering. Among them, the above-mentioned window size refers to the length of a continuous data segment selected when performing data processing. Taking the sliding average filtering algorithm as an example, when the window size is 10, it means that the number of continuous data points used each time the average value is calculated is 10. When calculating the filtered value at the current moment, the total of 10 data points at the current moment and before will be averaged. As time goes by, this window will continue to slide forward, and the average of the latest 10 data points will be calculated each time, so as to achieve the purpose of smoothing data and reducing noise interference.

[0067] Step 203, integrate the filtered data in all directions to obtain the resultant acceleration data. The above integration refers to converting the acceleration values ​​on the three axes after the above filtering into three vectors, and then merging the vectors by vector calculation. It should be noted here that the above vectors are converted in the following way. Since the three axes are directional, three vectors can be obtained by combining the above acceleration values. Taking the X-axis as an example, assuming that the acceleration value of the earphone on the X-axis is 5, a vector with a direction of the positive direction of the X-axis and a magnitude of 5 can be obtained. The above-mentioned resultant acceleration data refers to the modulus of the vector corresponding to the above-mentioned resultant acceleration, which is a numerical value.

[0068] In practice, the processor may integrate the various filtered data using the Pythagorean theorem to obtain the combined acceleration data.

[0069] Step 204 calculates the rate of change of the combined acceleration data within a preset time to obtain an acceleration change value. Calculating the rate of change of the combined acceleration data requires at least two combined acceleration data points (i.e., two values), so it takes a certain amount of time to collect the combined acceleration data points multiple times. Therefore, the preset time should ensure that at least two combined acceleration data points can be collected.

[0070] In practice, the processor can calculate the rate of change of the combined acceleration data by calculating the difference between the maximum and minimum values ​​of the combined acceleration data within a preset time period (e.g., 1 second) to obtain the acceleration change value. The built-in max() and min() functions in a programming language (e.g., Python) can be used to obtain the maximum and minimum values ​​of the combined acceleration data.

[0071] Step 205 : Calculate the standard deviation of the combined acceleration data within a preset time to obtain the acceleration standard deviation value. The preset time and the preset time in step 204 refer to the same time period.

[0072] In practice, the processor may calculate the standard deviation of all the combined acceleration data within a preset time (eg, 1 second) to obtain the acceleration standard deviation value.

[0073] In step 206, the acceleration change value and the acceleration standard deviation are compared with the acceleration change threshold and the standard deviation threshold, respectively. The acceleration change threshold and the standard deviation threshold are both pre-set values. When the user (i.e., the headphone wearer) exercises such that the acceleration change value of the headphones exceeds the acceleration change threshold and the acceleration standard deviation exceeds the standard deviation threshold within a certain period of time, this indicates that the user is exercising vigorously and may be producing a large amount of sweat. This undoubtedly increases the likelihood of sweat entering the headphones. Therefore, when it is determined that the user is exercising vigorously, increasing the data collection frequency of the humidity sensor can, to a certain extent, prevent damage to the internal components of the headphones caused by sweat.

[0074] In practice, the processor may compare the acceleration change value and the acceleration standard deviation value with an acceleration change threshold and a standard deviation threshold, respectively.

[0075] Step 207: In response to the acceleration change value being greater than the acceleration change threshold and the acceleration standard deviation being greater than the standard deviation threshold, control the humidity sensor to increase the sampling frequency. Figure 4 The humidity sensor described here corresponds to the humidity sensor.

[0076] In practice, the processor may determine whether to control the humidity sensor to increase its sampling frequency through a conditional statement. The logic for controlling the humidity sensor to increase its sampling frequency is to control the humidity sensor to increase its sampling frequency when the acceleration change value is greater than the acceleration change threshold and the acceleration standard deviation value is greater than the standard deviation threshold.

[0077] Step 208: In response to the acceleration change value not being greater than the acceleration change threshold or the acceleration standard deviation value not being greater than the standard deviation threshold, a detection step is performed.

[0078] In practice, the processor may determine whether to execute the detection step using a conditional statement. The judgment logic is that the detection step is executed when the acceleration change value is not greater than the acceleration change threshold or the acceleration standard deviation is not greater than the standard deviation threshold. It should be noted that the detection step is executed when both the acceleration change value is not greater than the acceleration change threshold and the acceleration standard deviation is not greater than the standard deviation threshold.

[0079] Steps 201-208, as an inventive feature of an embodiment of the present disclosure, address the technical issue of the inability to adjust the sensitivity of the headphone water ingress detection function based on actual operating scenarios. Many users enjoy wearing headphones while running or engaging in other strenuous exercise. During strenuous exercise, users may continuously exude sweat. Increased moisture in the operating environment of the headphones increases the risk of water ingress. To address this risk, the sensitivity of the headphone water ingress detection can be improved so that the processor can detect water ingress as quickly as possible, thereby reducing the possibility of damage to the headphones. Therefore, it is necessary to identify the operating environment of the headphones and adjust the sensitivity of the humidity sensor based on the characteristics of the operating environment. The factors that contribute to the inability to adjust the sensitivity of the headphone water ingress detection function based on actual operating scenarios are as follows: Currently, headphones lack the ability to identify the operating scenario. If these factors are addressed, the sensitivity of the headphone water ingress detection function can be adjusted based on actual operating scenarios. To achieve this, the present disclosure further provides a method for adjusting the sampling frequency of the humidity sensor in conjunction with an accelerometer. In one aspect, the accelerometer detects the user's movements. The accelerometer and humidity sensor communicate with the processor. If the processor determines the user is exercising vigorously and potentially sweating, it increases the humidity sensor's sampling frequency to minimize damage to the earphones' internal components. This allows the sensitivity of the earphones' water ingress detection function to be adjusted based on actual operating scenarios.

[0080] Some embodiments of the present disclosure provide a headset with a waterproof button, which can improve the user experience and increase the durability of the waterproof button. Specifically, the reason why the user experience and durability of most headsets with waterproof buttons are poor is that the commonly used waterproof method is to put a soft rubber ring on the button of the wireless headset, so that the button and the headset shell are tightly connected through the soft rubber ring, thereby achieving the purpose of waterproofing. However, the presence of the soft rubber ring will hinder the pressing and rebound of the button, affecting the user experience. In addition, the soft rubber ring will rub against the shell as the button moves, which will cause wear over time, thereby affecting the durability of the waterproof button. Based on this, some embodiments of the present disclosure provide an earphone with a waterproof button. The earphone with a waterproof button includes a button, a sealing gasket, a snap-on piece, a mounting slot, and an earphone body. The earphone body includes a housing; the mounting slot is provided on the housing; the button and the sealing gasket are coaxially assembled; the button and the sealing gasket are both mounted within the mounting slot; a through hole is provided at the bottom of the mounting slot; the through hole is configured to allow the lower end of the button to pass through; the snap-on piece is located within the housing and is configured to snap-on with the lower end; the button is configured to move along the mounting slot; and the sealing gasket is configured to deform as the button moves. Because the sealing gasket is fixedly mounted within the mounting slot, when the button is squeezed, the sealing gasket deforms under force but does not slide relative to the housing, reducing the possibility of wear. Furthermore, the sealing gasket, due to its own elastic force, provides a force to return the button to its original position after deformation, and this force can be fed back to the user through the button. This increases the durability of the waterproof button and improves the user experience.
