Description

Technical Field

[0001] This application belongs to the field of headphone device technology, specifically relating to a headphone device and its control method. Background Technology

[0002] With the rapid development of the electronics industry, various types of headphones have emerged. Compared with traditional headphones, Bluetooth headphones are increasingly favored by users due to their fewer wires and the fact that they do not need to be physically connected to electronic devices. In related technologies, Bluetooth headphones can be broadly divided into two categories: wired Bluetooth headphones and wireless Bluetooth headphones. Among them, wireless Bluetooth headphones offer better portability and battery life, making them one of the key research areas in the headphone field.

[0003] Wireless Bluetooth earbuds typically consist of earbuds and a charging case. The earbuds are stored in the case and can be charged through it. To achieve good charging performance, the charging electrodes on the case are usually designed to protrude towards the charging contacts on the earbuds, ensuring close contact between them. However, in some technologies, this protrusion on the charging electrodes creates significant resistance to the charging contacts during insertion, accelerating wear between them and leading to poor contact between the case and earbuds. This ultimately reduces the lifespan of both the earbuds and the case. Summary of the Invention

[0004] This application aims to provide an earphone device and its control method, which can improve the problem of poor contact between the earphone housing and the earphone, and extend the service life of the earphone housing.

[0005] In a first aspect, embodiments of this application provide an earphone device, including earphones, a housing, a movable contact, a driving component, and a sensing component. The earphones include charging contacts. The housing has a cavity for accommodating the earphones. The movable contact is disposed within the housing and has a first state and a second state. In the first state, the movable contact avoids the charging contacts; in the second state, the movable contact abuts against the charging contacts. The driving component is disposed within the housing and connected to the movable contact, driving the movable contact to switch between the first and second states. The sensing component senses the earphone's retracted state. During the process of placing the earphones into the cavity, the movable contact is in the first state; after the earphones are retracted into the cavity, the movable contact is in the second state.

[0006] Secondly, embodiments of this application propose a control method for the aforementioned headphone device, comprising:

[0007] Obtain the stored state of the headphones;

[0008] The active contact is controlled to switch between the first state and the second state according to the stored state of the earphone.

[0009] In the embodiments of this application, by setting a movable contact, a first state and a second state can be obtained. In the first state, the movable contact can avoid the charging contact. For example, when the earphone is placed in the cavity, the movable contact does not come into contact with the charging contact, which effectively reduces the resistance of the movable contact to the charging contact during the process of placing the earphone in the cavity, reduces the wear of the movable contact and the charging contact, and thus improves the service life of the earphone and the cavity. On the other hand, in the second state, the movable contact can abut against the charging contact, so that the movable contact and the charging contact are in close contact, improving the charging effect.

[0010] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0024] To improve the connection strength between the earbuds and the charging case in wireless Bluetooth earbuds, current technologies typically employ magnetic attraction to secure them. This can be achieved by placing magnetic elements on both the earbuds and the case, ensuring a tight fit and enhancing both connection strength and charging efficiency. However, the magnetic attraction creates an acceleration in the earbuds when inserted into the case, which increases as the distance between them decreases. In this case, the protruding charging electrodes on the case cause a significant impact on the charging contacts and electrodes upon contact, leading to deformation, peeling of the conductive coating, and other issues that severely impact the lifespan of the wireless Bluetooth earbuds.

[0025] Based on this, in order to solve the problem of short lifespan of headphone devices, the inventors of this application, after research, provide a headphone device and its control method.

[0028] Figure 3 yes Figure 1 Enlarged view of point A in the middle;

[0029] Figure 4 yes Figure 2 Enlarged view of point B in the middle;

[0030] like Figures 1 to 4 As shown, in some optional embodiments of this application, an earphone device is provided, including an earphone 10, a housing 20, a movable contact 30, a driving component 40, and a sensing component 50. The earphone 10 includes a charging contact 11. The housing 20 is provided with a cavity 21 for accommodating the earphone 10. The movable contact 30 is disposed within the housing 20 and is movable relative to the cavity 21. The movable contact 30 has a first state and a second state. In the first state, the movable contact 30 avoids the charging contact 11; in the second state, the movable contact 30 abuts against the charging contact 11. The driving component 40 is disposed within the housing 20 and connected to the movable contact 30, used to drive the movable contact 30 to switch between the first and second states. The sensing component 50 is used to sense the storage state of the earphone 10. During the process of inserting the earphone 10 into the cavity 21, the movable contact 30 is in the first state; after the earphone 10 is stored in the cavity 21, the movable contact 30 is in the second state.

[0031] The charging case 20 refers to the charging case in the wireless Bluetooth earphone 10, which provides a place to house the earphone 10 and can charge the earphone 10.

[0032] The active contact 30 refers to the conductive structure in the housing 20 used for electrical connection with the charging contact 11 on the earphone 10, such as a charging electrode. For example, the active contact 30 may be a charging spring or a charging probe.

[0033] The drive component 40 refers to the structure in the housing 20 used to drive the displacement of the movable contact 30, such as a motor or electromagnet.

[0034] The sensing component 50 refers to the structure in the housing 20 used to sense the relative distance between the housing 20 and the earphone 10, such as an optical distance sensor, an infrared distance sensor, or an ultrasonic distance sensor. Taking an optical distance sensor as an example, the sensing component 50 can be set inside the cavity 21 and face the opening of the cavity 21. The light emitted by the sensing component 50 can exit the cavity 21 through the opening. When the earphone 10 is put into the cavity 21, the earphone 10 blocks the light emitted by the sensing component 50. At this time, the earphone 10 can be considered to be in the state of being put into the cavity 21. When the earphone 10 is put into the cavity 21, the relative position of the earphone 10 and the cavity 21 is fixed, that is, the distance between the sensing component 50 and the earphone 10 is constant. Therefore, when the sensing component 50 measures that the relative distance between itself and the earphone reaches the distance threshold, the earphone 10 is considered to be in the state of being put into the cavity 21.

[0035] The storage state refers to the relative state relationship between the earphone 10 and the cavity 21, such as the earphone 10 being placed into the cavity 21 or the earphone 10 being stored in the cavity 21.

[0036] By providing a movable contact 30 with a first state and a second state, the charging electrode inside the housing 20 can be used in two states. In the first state, the movable contact 30 can avoid the charging contact 11. For example, when the earphone 10 is placed in the cavity 21, the movable contact 30 does not come into contact with the charging contact 11, effectively reducing the resistance of the movable contact 30 to the charging contact 11 during the process of placing the earphone 10 into the cavity 21, reducing the wear of the movable contact 30 and the charging contact 11, and thus improving the service life of the earphone 10 and the housing 20. On the other hand, in the second state, the movable contact 30 can come into contact with the charging contact 11, making the movable contact 30 and the charging contact 11 in close contact, thus improving the charging effect.

[0037] Optionally, the housing 20 may also have an opening that communicates with the chamber 21, through which the earphone 10 can be inserted into the chamber 21. Exemplarily, at least a portion of the earphone 10 extends outside the chamber 21 through the opening, so that the earphone 10 can be removed from the chamber 21.

[0038] Optionally, the housing 20 may include a housing cap, which is rotatably connected to the housing 20. An opening is provided on the end face of the housing 20 facing the housing cap. At least a portion of the earphone 10 extends outside the housing 20 through the opening. The housing cap can cover the end face and accommodate the portion of the earphone 10 extending outside the housing 20. Optionally, the movable contact 30 may be a plate-shaped electrode, and the driving assembly 40 may be a driving motor. One axial end of the plate-shaped electrode is connected to the rotating shaft of the driving motor, so that the plate-shaped electrode can rotate about the rotating shaft of the driving motor. When the earphone 10 is placed in the cavity 21, the second state is when the plate-shaped electrode rotates to a position abutting against the charging contact 11, and the first state is when the plate-shaped electrode rotates to a position not abutting against the charging contact 11.

[0039] Optionally, a first fixed magnet may be provided inside the housing 20, and a second fixed magnet may be provided on the earphone 10. The relative position of the earphone 10 and the housing 20 can be fixed by the attraction between the first fixed magnet and the second fixed magnet.

[0040] During use, when the earphone 10 is placed outside the cavity 21, the movable contact 30 is adjusted to the first state. When the earphone 10 needs charging or storage, it is placed inside the cavity 21. After the earphone 10 is placed in a preset position within the cavity 21, the movable contact 30 is controlled to enter the second state, thus establishing an electrical connection between the housing 20 and the earphone 10. For example, the preset position refers to the position of the earphone 10 within the cavity 21 in the second state, a position that ensures the movable contact 30 abuts against the charging contact 11.

[0041] In other applications, when the earphone 10 is outside the cavity 21, the movable contact 30 is adjusted to a second state. When the earphone 10 needs charging or storage, and is placed inside the cavity 21, the sensing component 50 acquires a distance signal between the earphone 10 and the housing 20, and controls the movable contact 30 to enter a first state. When the earphone 10 is placed in a preset position inside the cavity 21, if the distance signal acquired by the sensing component 50 is less than or equal to a distance threshold, the movable contact 30 is controlled to enter a second state, thus establishing an electrical connection between the housing 20 and the earphone 10. For example, the distance threshold is the distance between the earphone 10 and the sensing component 50 when the earphone 10 is in the preset position.

[0042] like Figures 1 to 4 As shown, in some optional embodiments of this application, the headphone device further includes a power supply component disposed within the housing 20. The movable contact 30 includes a connecting portion 32, a movable portion 31, and an elastic portion 33. The connecting portion 32 is electrically connected to the power supply component, the movable portion 31 is movable relative to the connecting portion 32, the elastic portion 33 is connected to the connecting portion 32 and the movable portion 31, and the driving component 40 drives the movable portion 31 to move.

[0043] The elastic part 33 refers to the part that can store elastic potential energy. For example, the elastic part 33 may have an energy storage state and an energy release state. In the first state, the movable part 31 avoids the charging contact 11 and the elastic part 33 enters the energy storage state. In the second state, the elastic part 33 enters the energy release state and the movable part 31 comes into contact with the charging contact 11.

[0044] The power supply components refer to the structures in the compartment 20 that provide electrical energy, such as batteries and charging circuits.

[0045] First, by providing the movable part 31, the portion of the movable contact 30 that abuts against the charging contact 11 can be made relatively independent. This allows the movable contact 30 to switch between the first and second states simply by adjusting the position of the movable part 31, reducing the difficulty of switching between the first and second states. Second, by providing the connecting part 32, the movable contact 30 can have a portion that is fixedly connected to the housing 20, facilitating the connection between the movable contact 30 and the power supply component and reducing the difficulty of connecting the movable contact 30 and the power supply component. Third, by providing the elastic part 33, not only can the movable part 31 and the connecting part 32 be connected to ensure the integrity of the movable contact 30, but it can also store a portion of energy during the switching between the first and second states, so that the switching from the first state to the second state does not depend on the driving component 40.

[0046] Optionally, the elastic part 33 can be bent, such as the elastic part 33 being U-shaped, and the two ends of the elastic part 33 are respectively used to connect the movable part 31 and the connecting part 32.

[0047] Optionally, the relationship between the energy storage state and the energy release state of the elastic part 33 and the first state and the second state can also be that in the first state, the elastic part 33 enters the energy release state, and in the second state, the elastic part 33 enters the energy storage state.

[0048] Optionally, the connecting part 32, the movable part 31, and the elastic part 33 can be an integrally formed structure, such as a charging spring.

[0049] Optionally, the connecting part 32, the movable part 31, and the elastic part 33 may be made of conductive materials, such as gold, silver, copper, aluminum, etc. For example, the current output by the power supply component can be conducted through the connecting part 32 to the elastic part 33, and then from the elastic part 33 to the movable part 31.

[0050] like Figures 1 to 4 As shown, in some optional embodiments of this application, the driving component 40 includes a first driving part 41 and a second driving part 42, the movable part 31 is connected to the first driving part 41, the connecting part 32 is connected to the second driving part 42, and the first driving part 41 and the second driving part 42 can attract or repel each other through magnetism.

[0051] By providing a first drive unit 41 and a second drive unit 42, the movable part 31 can be moved relative to the connecting part 32 by magnetic drive, which simplifies the structure of the drive assembly 40 and makes it easier to install the drive assembly 40 inside the compartment 20.

[0052] Optionally, the movable part 31 may follow the first drive part 41.

[0053] Optionally, the first driving part 41 may be an electromagnetic structure, such as an electromagnet, and the second driving part 42 may be a material that can be attracted by magnetism, such as iron, cobalt, nickel, etc., so as to realize the attraction or repulsion of the first driving part 41 to the second driving part 42.

[0054] Optionally, the second driving part 42 may adopt an electromagnetic structure, such as an electromagnet, and the first driving part 41 may be a material that can be attracted by magnetism, such as iron, cobalt, nickel, etc., so as to realize the attraction or repulsion of the second driving part 42 to the first driving part 41.

[0055] Optionally, both the first drive unit 41 and the second drive unit 42 may employ an electromagnetic structure.

[0056] like Figures 1 to 4 As shown, in some optional embodiments of this application, in the first state, the active part 31 and the connecting part 32 are stacked, and the active part 31 is located on the side of the connecting part 32 near the charging contact 11. The first driving part 41 is disposed on the side of the active part 31 facing the connecting part 32, and the second driving part 42 is disposed on the side of the connecting part 32 facing the active part 31.

[0057] By placing the first drive unit 41 on the side of the movable part 31 facing the connecting part 32 and the second drive unit 42 on the side of the connecting part 32 facing the movable part 31, the distance between the first drive unit 41 and the second drive unit 42 can be effectively shortened, resulting in a larger interaction force between the first drive unit 41 and the second drive unit 42, which facilitates the mutual attraction between the first drive unit 41 and the second drive unit 42. On the other hand, by placing the first drive unit 41 and the second drive unit 42 directly on the surfaces of the movable part 31 and the connecting part 32, the impact of setting the drive assembly 40 on the structure of the compartment 20 can also be reduced.

[0058] Optionally, the first driving part 41 may be glued to the surface of the movable part 31, and the second driving part 42 may be glued to the surface of the connecting part 32.

[0059] like Figures 1 to 4As shown, in some optional embodiments of this application, the first driving part 41 includes at least one first magnetic element, and the second driving part 42 includes at least one second magnetic element. The first and second magnetic elements are able to attract or repel each other magnetically. Exemplarily, one first and one second magnetic element are each provided, and each of the first and second magnetic elements can be an electromagnet. By using electromagnets for the first driving part 41 and the second driving part 42, the interaction force between the first driving part 41 and the second driving part 42 can be significantly increased, facilitating mutual attraction or repulsion between the first driving part 41 and the second driving part 42.

[0060] Optionally, the side of the first driving part 41 facing the second driving part 42 and the side of the second driving part 42 facing the first driving part 41 are opposite magnetic poles. For example, the side of the first driving part 41 facing the second driving part 42 is the S pole and the side of the second driving part 42 facing the first driving part 41 is the N pole, or the side of the first driving part 41 facing the second driving part 42 is the N pole and the side of the second driving part 42 facing the first driving part 41 is the S pole.

[0061] Optionally, the side of the first driving part 41 facing the second driving part 42 and the side of the second driving part 42 facing the first driving part 41 are magnetic poles of the same polarity. For example, the side of the first driving part 41 facing the second driving part 42 is the S pole, and the side of the second driving part 42 facing the first driving part 41 is also the S pole; or the side of the first driving part 41 facing the second driving part 42 is the N pole, and the side of the second driving part 42 facing the first driving part 41 is also the N pole. By controlling the magnetic strength of the first driving part 41 or the second driving part 42, the earphone can switch between the first state and the second state. For example, when the movable contact 30 is not subjected to external force, the earphone is in the first state. At this time, the circuit in the circuit increases, and thus the magnetism increases, causing the first driving part 41 and the second driving part 42 to repel and separate, reaching the second state.

[0062] like Figures 1 to 4 As shown, in some optional embodiments of this application, when the earphone 10 is housed in the cavity 21, a receiving groove 22 is provided on the side of the cavity 21 facing the charging contact 11. In a first state, the movable contact 30 is disposed in the receiving groove 22. In a second state, the movable part 31 extends from inside the receiving groove 22 to outside the receiving groove 22 and abuts against the charging contact 11.

[0063] By setting the receiving groove 22, the position of the movable contact 30 can be connected to the cavity 21, which facilitates the setting of the movable contact 30 and reduces interference with the switching between the first and second states.

[0064] Optionally, the position of the movable contact 30 relative to the cavity 21 is determined by the position of the charging contact 11 in a preset position. For example, if the charging contact 11 is located in the cavity 21 on the side away from the opening in the preset position, then the movable contact 30 is located in the housing 20 at the end away from the opening. Exemplarily, the position of the receiving groove 22 relative to the cavity 21 is determined by the position of the movable contact 30. For example, if the movable contact 30 is located in the housing 20 at the end away from the opening, then the receiving groove 22 can be formed by recessing the bottom wall of the cavity 21 towards the side away from the earphone 10.

[0065] In some alternative embodiments of this application, the headphone device further includes a control component electrically connected to the drive component 40 and the sensing component 50, for controlling the driving force on the first drive unit 41 and the second drive unit 42.

[0066] The driving force refers to the force that drives the first driving part 41 and the second driving part 42 to move away from or towards each other, such as magnetic force, elastic force, etc.

[0067] The control component refers to the structure within the housing 20 that can control the drive component 40 and the sensing component 50, such as a CPU chip or a microcontroller.

[0068] By setting up a control component, the drive component 40 can be controlled according to the distance information provided by the sensing component 50, thereby controlling the active contact 30 to be in the first state or the second state.

[0069] Optionally, the control component can control the magnetism on the first driving unit 41 and the second driving unit 42, such as the generation or elimination of magnetism, the repulsion or attraction of magnetism, or the increase or decrease of magnetism. For example, the control component can control the on / off state of the electromagnet circuit to control the generation or elimination of magnetism, control the magnitude of the current input to the electromagnet to control the increase or decrease of magnetism, and control the direction of the current input to the electromagnet to control the repulsion or attraction of magnetism.

[0070] Optionally, the control component can control the increase or decrease of the magnetism on the first drive unit 41 and the second drive unit 42. For example, the control component can control the magnitude of the current in the electromagnet circuit to control the increase or decrease of the magnetism, so that the switching speed between the first state and the second state can be controlled.

[0071] like Figures 1 to 4 As shown, in some optional embodiments of this application, a buffer hook 34 that bends toward the connecting part 32 is provided at one end of the movable part 31 away from the elastic part 33.

[0072] By providing a buffer hook 34, a buffer structure can be provided between the movable part 31 and the connecting part 32, reducing the impact between the movable part 31 and the connecting part 32. On the other hand, in the first state, a certain amount of redundant space can be provided between the movable part 31 and the connecting part 32, reducing the risk that the movable part 31 and the connecting part 32 will be squeezed due to excessive contact in the first state.

[0073] Figure 5 This is a flowchart of the control method in some embodiments of this application.

[0074] like Figure 5 As shown, in some optional embodiments of this application, a control method for the above-mentioned headphone device is provided, including:

[0075] S100: Obtain the storage status of the earphone 10;

[0076] S200: Based on the storage state of the earphone 10, control the active contact 30 to switch between the first state and the second state.

[0077] The storage status can be detected and determined by the sensing component 50.

[0078] In S200, the control of the active contact 30 can be implemented by the drive assembly 40.

[0079] By setting steps S100 to S200, the action of inserting the earphone 10 into the cavity 21 and the action of controlling the movable contact 30 can be integrated, reducing the difficulty of operating the earphone device and realizing automatic control of the state switching on the movable contact 30.

[0080] Figure 6 This is a flowchart of the control method in some other embodiments of this application.

[0081] like Figure 6 As shown, in some optional embodiments of this application, the control method further includes:

[0082] S310. When the obtained storage status is that the earphone 10 is being placed into the cavity 21, the control contact 30 is put into the first state.

[0083] S320. When the obtained storage state is that the earphone 10 is stored in the cavity 21, the control contact 30 enters the second state.

[0084] In S310, taking the sensing component 50 as an example of using an optical distance sensor, the light emitted by the sensing component 50 towards the outside of the cavity 21 is blocked by the earphone 10 when it is being stored in the cavity 21. At this time, the storage state of the earphone 10 can be considered as the earphone 10 being placed into the cavity 21. When the earphone 10 is stored in the cavity 21, the relative position of the earphone 10 and the cavity 21 is fixed, that is, the distance between the sensing component 50 and the earphone 10 is constant. Therefore, when the value measured by the sensing component 50 reaches the distance threshold, the storage state of the earphone 10 is considered as the earphone 10 being stored in the cavity 21.

[0085] The distance between the earphone 10 and the housing 20 reaches the distance threshold, which means that the distance between the earphone 10 and the housing 20 is less than or equal to the distance threshold.

[0086] By setting steps S100 to S400, when the earphone 10 is not in the chamber 21, the active contact 30 is in the second state (at this time, the active contact 30 is not subject to external force), reducing the duration of the active contact 30 in the first state, so that the elastic part 33 is in the energy-releasing state, reducing the risk of damage to the elastic part 33, and also shortening the duration of the housing 20 in the first state of additional energy consumption, improving the battery life of the housing 20, and making it easier for the control component to control the housing 20.
