Description

Technical Field

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

[0002] As people engage in more sports and outdoor activities, wireless headphones are used in a variety of scenarios, and the requirements for their waterproof performance are becoming higher and higher. 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.

[0003] However, when the above method is used to waterproof wireless headphones, the following technical problems often occur: The presence of the soft rubber ring will hinder the pressing and rebounding 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, thus affecting the durability of the waterproof button.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure concept and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

[0017] 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 headset 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 housing 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 rebounding of the button, affecting the user experience.

Based on this, some embodiments of the present disclosure provide an earphone with a waterproof button, wherein the earphone with a waterproof button comprises a button, a sealing pad, a card connector, a mounting groove and an earphone body, wherein the earphone body comprises a housing; the mounting groove is arranged on the housing; the button and the sealing pad are coaxially assembled; the button and the sealing pad are both installed in the mounting groove; a through hole is arranged at the bottom of the mounting groove; the through hole is configured to allow the lower end of the button to pass through; the card connector is located inside the housing, and the card connector is configured to be able to be engaged with the lower end; the button is configured to be able to move along the mounting groove; the sealing pad is configured to be able to deform with the movement of the button. Also, because the sealing pad is fixedly installed in the mounting groove, when the button is squeezed, the sealing pad will be deformed by force, but will not slide relative to the housing, reducing the possibility of wear. And the sealing pad will provide the button with a force to return to its original position after deformation due to its own elastic force, and the force can be fed back to the user by the button. Thus, the durability of the waterproof button is increased and the user experience is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] Figure 1 It is a partial cross-sectional view of an earphone with waterproof buttons according to some embodiments of the present disclosure. Figure 1 It includes a card connecting piece 1, a sealing pad 2, a button 3, a limiting groove 4, a mounting groove 5, a shell 6, and a limiting protrusion 7.

[0027] Figure 2 It is a partial cross-sectional view of the earphone with waterproof buttons according to some embodiments of the present disclosure from another perspective. Figure 2 It includes a sealing pad 2, a button 3, a shell 6, a circuit board 8, and an electronic button 9.

[0028] Figure 3 It is a cross-sectional schematic diagram of the sealing gasket of some embodiments of the present disclosure in the installed state in some embodiments. Figure 3It includes a sealing pad 2, a key 3, a mounting groove 5, a housing 6, a key sealing groove 10, an upper sealing protrusion 11, a fixed sealing groove 12, and a lower sealing protrusion 13. Figure 3 In the figure, for the convenience of illustration, the upper sealing protrusion 11 and the lower sealing protrusion 13 on the sealing gasket 2 are not completely attached to the key sealing groove 10 and the fixed sealing groove 12. In the actual installation state, the surface of the upper sealing protrusion 11 is attached to the key sealing groove 10, and the lower sealing protrusion 13 is attached to the fixed sealing groove 12.

[0029] In some embodiments, the earphone with waterproof button comprises a button 3, a sealing pad 2, a card connector 1, a mounting groove 5 and an earphone body, and the earphone body comprises a housing 6. The sealing pad 2 is a structure similar to a truncated cone or a prism, and is hollow inside, and has openings on the upper and lower surfaces. The sealing pad 2 can be made of a soft rubber material (such as rubber or silicone, etc.) that is elastic and waterproof, and is not specifically limited here. One function of the sealing pad 2 is to achieve the waterproof function of the earphone. The card connector 1 can be a sheet structure with a bend. The card connector 1 is located inside the housing 6, and the card connector 1 is configured to be able to be clamped with the lower end. The card connector 1 can limit the button 3 to move only within a certain range in the axial direction. In order to achieve the above effect, the material of the card connector 1 can include but is not limited to one or more of the following: metal, plastic, carbon fiber. The mounting groove 5 is a groove provided on the housing 6. The main function of the mounting groove 5 is to accommodate the button 3 and the sealing pad 2, and limit the button 3 to move up and down only along the axial direction of the mounting groove 5. The button 3 and the sealing pad 2 are coaxially assembled in the installation groove 5. A through hole may be provided at the bottom of the installation 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 to transmit the user's operation to the functional structure inside the earphone. The sealing pad 2 can also support the button 3. When the user presses the button 3, the sealing pad 2 gives the user a pressing feedback due to its own elasticity, and supports the button 3 to return to its initial position before pressing after the user completes the pressing operation. During the user's pressing process, the sealing pad 2 will be deformed, and its hollow structural design provides itself with a deformation space.

[0030] Alternatively, if Figure 1 As shown, the top surface of the sealing pad 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 upper and lower surfaces of the sealing pad 2 tightly connects the button 3 with the mounting groove 5, and to a certain extent prevents the sealing pad 2 from sliding with the movement of the button 3, ensuring the user's pressing feel.

[0031] Alternatively, if Figure 2As 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 manner 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.

[0032] Optionally, the earphone body may include a power source. The power source may be a lithium-ion battery, which is not specifically limited here. The power source may be electrically connected to the circuit board 8 to supply power to the circuit board 8. The electrical connection may be through a wire. It should be noted that the power source is not shown in the accompanying drawings.

[0033] Alternatively, if Figure 2 As shown, the earphone body may further include an electronic button 9. The function of the electronic button 9 includes serving 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 patch-type button, which is not specifically limited here. The electronic button 9 may be electrically connected to the circuit board 8. The electrical connection method may be welding, which is not specifically limited here. The electronic button 9 may be coaxially assembled with the button 3 to ensure that the electronic button 9 can be triggered when the button 3 is pressed down. During use, the user presses the button 3, and the button 3 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, the electronic button 9 can communicate with the circuit board 8 through the change of the on-off state. By pressing the electronic button 9, the transmission and execution of operation instructions such as play, pause, switch songs, and adjust the volume can be realized. In addition, the electronic button 9 also has a certain resilience, which can also provide a certain resilience to the button 3.

[0034] Alternatively, if Figure 2 As 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 protruding from the inner wall of the housing 6 to the inside 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.

[0035] Alternatively, if Figure 1As 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. Reference may be made here Figure 1 The thickness of the above-mentioned card plate 1 can be less than the height of the above-mentioned limit groove 4. It should be noted here that the above-mentioned height refers to the length of the above-mentioned limit 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 limit groove 4, the above-mentioned key 3 can move in the axial direction.

[0036] Alternatively, if 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 accurate, 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).

[0037] Optionally, the earphone with waterproof button may further include a charging compartment. The charging compartment may be a rectangular parallelepiped with a cover. The charging compartment is mainly used to charge the earphone, so a battery may be built in. A structure capable of establishing electrical connection with the earphone is also provided.

[0038] Alternatively, if 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 structure extending toward the outside of 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 arranged on the side of the mounting groove 5. The height of the lower sealing protrusion 13 and the fixed sealing groove 12 may be equal. The depth of the fixed sealing groove 12 may be equal to the extension length of the lower sealing protrusion 13. The purpose of such arrangement is that the lower sealing protrusion 13 may be more adaptably installed in the fixed sealing groove 12, so as to achieve the purpose of fixing the lower end surface of the sealing gasket 2 on 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 structure 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 arranged on the side of the key 3. The height of the upper sealing protrusion 11 may be equal to that of the key sealing groove 10. The depth of the key sealing groove 10 may be equal to the extension length of the upper sealing protrusion 11. The purpose of such arrangement is that the upper sealing protrusion 11 may 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 may 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 resilience may become weak. 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 sealing gasket 2 on the bottom surface of the mounting groove 5, and fix the upper end of the sealing gasket 2 on the button 3, so that the rebound force of the electronic button 9 can be transmitted to the sealing gasket 2 through the button 3, providing a certain degree of assistance to the rebound of the sealing gasket 2.

[0039] The above optional embodiment, as an inventive point of the embodiment of the present disclosure, solves the technical problem that "the sealing gasket made of soft rubber material is prone to non-rebound after long-term use". The non-rebound of the sealing gasket may affect the waterproof effect of the headphone button, so it is necessary to prevent this. The factors that cause the sealing gasket made of soft rubber material to be prone to non-rebound after long-term use are as follows: the soft rubber material will gradually age with the extension of the use time, which will cause it to be prone to non-rebound, and there is currently no structure designed specifically to prevent the sealing gasket from not rebounding. If the above factors are solved, the effect of reducing the possibility of the sealing gasket not rebounding can be achieved. In order to achieve this effect, the present disclosure further provides a structure that can assist the sealing gasket to rebound. On the one hand, the upper and lower ends of the sealing gasket are fixed respectively. On the other hand, after the user completes the downward pressing action and retracts the finger, the key will rebound due to the rebound force of the electronic key. Because the upper and lower ends of the sealing gasket are respectively installed in a fixed fixed sealing groove and a key sealing groove that moves with the key. This will form a stretching effect on the sealing gasket. As a result, the possibility of the sealing gasket not rebounding is reduced.

[0040] Further references Figure 4 , which shows some processes 100 that can be implemented by the processor of some embodiments of the present disclosure.

[0041] 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 through a wire 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 cycle steps: Step 101, controlling the humidity sensor to collect humidity data in the earphone at a preset frequency to obtain initial humidity data.

[0042] Among them, the preset frequency can be to collect data once per second. The initial humidity data refers to the raw data collected by the humidity sensor without any processing. These data are presented in a sensor-specific format, which may be a binary complement, a raw voltage value or other forms. Due to the influence of electrical noise, environmental interference, etc., the raw data may fluctuate and have errors and cannot be used directly to judge the humidity condition, so subsequent format conversion and other processing are required to obtain a value that accurately reflects the actual humidity.

[0043] 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.

[0044] Step 102, preprocessing the initial humidity data to obtain a humidity value. The initial humidity data refers to the raw data collected by the humidity sensor without any processing, and needs to be format converted to obtain a value that accurately reflects the actual humidity. Therefore, the initial humidity data needs to be preprocessed. The humidity value refers to a value that represents the humidity of the environment where the humidity sensor is located.

[0045] In practice, taking the above humidity sensor outputting an analog voltage signal proportional to humidity as an example, the above processor can convert it into a digital quantity through an analog-to-digital converter (ADC). Assuming that the above humidity sensor outputs a voltage range of 0-3V corresponding to a humidity of 0%-100%RH, the ADC accuracy is 12 bits, and its output digital quantity 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.

[0046] Step 103: compare the humidity value with a preset humidity threshold.

[0047] In practice, the headset manufacturer can pre-define a humidity threshold in the program of the above processor according to the waterproof performance of the headset, for example, setting the threshold to 65%RH. The comparison step can be implemented through a conditional statement.

[0048] Step 104 , in response to the humidity value being less than the humidity threshold, executing a loop step.

[0049] The above-mentioned cycle steps refer to step 101 to step 103. The purpose is to continuously detect the earphone when water ingress is not detected.

[0050] 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.

[0051] Step 105: In response to the humidity value being greater than or equal to the humidity threshold, perform emergency processing.

[0052] Among them, the above-mentioned emergency treatment refers to shutting down the earphones to reduce the possibility of damage to the internal electronic components when the earphones are powered on after water enters them.

[0053] In practice, the processor can 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 of the earphone.

[0054] 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: At present, earphones lack detection and protection measures for water ingress. When water enters the earphones, the earphones are still powered on, 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.

[0055] Further references Figure 5 , which shows some other processes 200 that can be implemented by the processor of some embodiments of the present disclosure.

[0056] Optionally, the earphone body may further include an acceleration sensor. The acceleration sensor may be communicatively connected to the processor. The processor is further configured to perform the following detection steps: Step 201: collect data from the acceleration sensor at a preset frequency to obtain acceleration data in all directions, wherein the acceleration data in all directions may refer to acceleration values ​​of the earphone on three axes (X, Y, Z).

[0057] 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.

[0058] Step 202: filter the acceleration data in each direction to obtain filtered data in each direction. The filtering process is to reduce noise interference. The filtered data in each direction refers to the acceleration value on each axis after filtering.

[0059] In practice, the processor may use a sliding average filtering algorithm to smooth the acceleration data in each direction (i.e., the acceleration value on each axis) according to a preset window size (e.g., a window size of 10), and obtain the acceleration values ​​on the three axes after filtering. The window size refers to the length of a continuous data segment selected during 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, a total of 10 data points at and before the current moment are averaged. As time goes by, the window will continue to slide forward, and the average value of the latest 10 data points will be calculated each time, thereby achieving the purpose of smoothing data and reducing noise interference.

[0060] Step 203, integrate the filtered data in all directions to obtain combined 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 obtained by conversion in the following way. Since the three axes are directional, three vectors can be obtained in combination with the above acceleration values. Taking the X-axis as an example, assuming that the acceleration value of the headset 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 combined acceleration data refers to the modulus of the vector corresponding to the above combined acceleration, which is a numerical value.

[0061] In practice, the processor may integrate the various filtering data using the Pythagorean theorem to obtain the combined acceleration data.

[0062] Step 204, within a preset time, calculate the change rate of the combined acceleration data to obtain the acceleration change value. Calculating the change rate of the combined acceleration data requires at least two combined acceleration data (i.e., two values), so it takes a certain amount of time to collect the combined acceleration data multiple times. Therefore, the preset time should ensure that at least two combined acceleration data can be collected.

[0063] In practice, the processor can calculate the change rate of the combined acceleration data by calculating the difference between the maximum value and the minimum value of the combined acceleration data within a preset time (such as 1 second) to obtain the acceleration change value. The built-in max() and min() functions in a programming language (such as Python) can be used to obtain the maximum and minimum values ​​in the combined acceleration data.

[0064] Step 205, calculating 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.

[0065] 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.

[0066] Step 206, compare the acceleration change value and the acceleration standard deviation value with the acceleration change threshold value and the standard deviation threshold value respectively. The acceleration change threshold value and the standard deviation threshold value are both preset values. When the user (i.e., the headphone wearer) moves so that the acceleration change value of the headphone exceeds the acceleration change threshold value within a certain period of time and the acceleration standard deviation value exceeds the standard deviation threshold value, it means that the user's exercise level is relatively intense and may excrete a large amount of sweat, which will undoubtedly increase the possibility of sweat entering the headphone. Therefore, when it is determined that the user is in a state of intense exercise, increasing the data collection frequency of the humidity sensor can avoid damage to the internal components of the headphone by sweat to a certain extent.

[0067] 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.

[0068] 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 one used.

[0069] In practice, the processor can determine whether it is necessary to control the humidity sensor to increase the sampling frequency through a conditional statement. The logic of controlling the humidity sensor to increase the sampling frequency is that 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, the humidity sensor is controlled to increase the sampling frequency.

[0070] 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. The detection step refers to steps 201 to 206.

[0071] In practice, the processor can determine whether to execute the detection step through a conditional statement. The judgment logic is that when the acceleration change value is not greater than the acceleration change threshold or the acceleration standard deviation value is not greater than the standard deviation threshold, the detection step is executed. It should be noted that when the acceleration change value is not greater than the acceleration change threshold and the acceleration standard deviation value is not greater than the standard deviation threshold, the detection step is executed.

[0072] As an inventive point of an embodiment of the present disclosure, the above steps 201 to 208 solve the technical problem that "the sensitivity of the earphone water ingress detection function cannot be adjusted according to the actual operation scene". Many users like to wear earphones to run or do other strenuous exercises. During strenuous exercise, users may continuously excrete sweat. The increase in moisture in the operating environment of the earphone increases the risk of water ingress into the earphone. In order to cope with this risk, the above processor can detect whether the earphone has water ingress as quickly as possible by improving the sensitivity of the earphone water ingress detection, so as to reduce the possibility of earphone damage to a certain extent. Therefore, it is necessary to identify the operating environment of the earphone and adjust the sensitivity of the humidity sensor according to the characteristics of the operating environment. The factors that cause the sensitivity of the earphone water ingress detection function to be unable to be adjusted according to the actual operation scene are as follows: At present, the earphone lacks the function of identifying the earphone operation scene. If the above factors are solved, the effect that the sensitivity of the earphone water ingress detection function can be adjusted according to the actual operation scene can be achieved. In order to achieve this effect, the present disclosure further provides a method for adjusting the sampling frequency of the humidity sensor in combination with an acceleration sensor. On the one hand, the user's action is detected by the acceleration sensor. On the other hand, the acceleration sensor and humidity sensor are connected to the processor for communication. When the processor determines that the user is in a state of intense exercise and may sweat a lot, it increases the sampling frequency of the humidity sensor to avoid sweat from damaging the internal components of the earphones as much as possible. In this way, the sensitivity of the earphone water ingress detection function can be adjusted according to the actual operating scenario.

[0073] 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 headset 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 housing 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 rebounding of the button, affecting the user experience. In addition, the soft rubber ring will rub against the housing 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, wherein the earphone with a waterproof button comprises a button, a sealing pad, a card connector, a mounting groove and an earphone body, wherein the earphone body comprises a housing; the mounting groove is arranged on the housing; the button and the sealing pad are coaxially assembled; the button and the sealing pad are both installed in the mounting groove; a through hole is arranged at the bottom of the mounting groove; the through hole is configured to allow the lower end of the button to pass through; the card connector is located inside the housing, and the card connector is configured to be able to be engaged with the lower end; the button is configured to be able to move along the mounting groove; the sealing pad is configured to be able to deform with the movement of the button. Also, because the sealing pad is fixedly installed in the mounting groove, when the button is squeezed, the sealing pad will be deformed by force, but will not slide relative to the housing, reducing the possibility of wear. And the sealing pad will provide the button with a force to return to its original position after deformation due to its own elastic force, and the force can be fed back to the user by the button. Thus, the durability of the waterproof button is increased and the user experience is improved.
