[0036] Now, various exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application.

[0038] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0039] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0041] When the head-mounted device according to the embodiment of the present application needs to be stored, it can be switched from the worn state to the stored state and folded arbitrarily as needed, solving the problem that the storage of the head-mounted device occupies a large space, thereby improving the user experience. The head-mounted device according to the embodiment of the present application can be, for example, a head-mounted earphone.

[0042] Figures 1 to 3 Shows a schematic structural diagram of a head-mounted device related to an embodiment of the present application. As Figures 1 to 3 shown, the head-mounted device 100 may include a left main body portion 110, a right main body portion 120, a plurality of headband support blocks 130, and a cable 140. Among them, the cable 140 is sequentially connected to the left main body portion 110, the plurality of headband support blocks 130, and the right main body portion 120.

[0043] The left main body portion 110 and the right main body portion 120 in this embodiment are two main parts of the head-mounted device 100. In one example, components such as ear shells and sound-emitting units may be included in the left main body portion 110 and the right main body portion 120.

[0044] The "left" and "right" in this embodiment can be determined according to the left and right directions when the user wears the head-mounted device. Of course, they can also be determined according to other rules, which are not specifically limited here.

[0045] When in close contact, the headband support block 130 in this embodiment serves as a support component for the headband in the head-mounted device 100 to support the headband.

[0046] The cable 140 in this embodiment can be retracted into the interior of at least one of the left main body portion 110 and the right main body portion 120, or can be released from the interior of at least one of the left main body portion 110 and the right main body portion 120.

[0047] The head-mounted device 100 in this embodiment has a wearing state and a storage state. The wearing state in this embodiment is the state for wearing. The storage state in this embodiment is the state for storage.

[0048] When the state of the head-mounted device 100 is switched from the wearing state to the storage state, the cable 140 is released from at least one of the left main body portion 110 and the right main body portion 120, causing the plurality of headband support blocks 130 to spread apart. When the state of the head-mounted device 100 is switched from the storage state to the wearing state, the cable 140 retracts into the interior of at least one of the left main body portion 110 and the right main body portion 120, causing the plurality of headband support blocks 130 to come into close contact with each other to form the headband of the head-mounted device.

[0049] It can be understood that when the cable 140 is released from at least one of the left main body portion 110 and the right main body portion 120, the cable 140 becomes slack, causing the mutual force between the headband support blocks 130 connected to the cable 140 to become smaller until they are dispersed. When the cable 140 retracts into the interior of at least one of the left main body portion 110 and the right main body portion 120, the cable 140 becomes taut, causing the headband support blocks 130 connected to the cable 140 to gradually approach until the headband support blocks 130 come into contact with each other. When the cable 140 continues to retract into the interior of at least one of the left main body portion 110 and the right main body portion 120, the mutual force between the headband support blocks gradually increases, causing the plurality of headband support blocks 130 to come into close contact with each other.

[0050] In the embodiments of the present application, when the user needs to store the head-mounted device, the state of the head-mounted device can be switched from the worn state to the stored state, so that the user can fold it arbitrarily according to needs, solving the problem that the storage of the head-mounted device occupies a large space, thereby improving the user experience. When the user needs to use the head-mounted device, the state can be switched from the stored state to the worn state.

[0051] In one example, the headband support blocks 130 are in a state of close contact or dispersion with each other, which can be determined by whether the mutual force between each headband support block 130 is greater than or equal to a preset value. When the mutual force between each headband support block 130 is greater than or equal to the preset value, it is determined that the headband support blocks 130 are in close contact with each other; when the mutual force between each headband support block 130 is less than the preset value, it is determined that the headband support blocks 130 are in a dispersed state.

[0052] In some embodiments, through holes can be provided in the headband support blocks 130. The cable 140 passes through the through holes of each headband support block 130. When the head-mounted device is switched from the stored state to the worn state, the cable 140 contracts along the through holes into the interior of at least one of the left main body portion and the right main body portion. When the head-mounted device is switched from the worn state to the stored state, the cable 140 is released from at least one of the left main body portion and the right main body portion to the outside of the through holes.

[0053] In this embodiment, the specific shape of the through hole is not limited, as long as it can enable the cable to move freely.

[0054] In some other embodiments, a receiving structure for receiving the cable 140 can also be provided on the upper surface or the lower surface of the headband support block 130. The cable 140 contracts along the receiving structure into the interior of at least one of the left main body portion and the right main body portion, or the cable 140 is released from at least one of the left main body portion and the right main body portion to the outside of the receiving structure.

[0055] In some embodiments, the number of the headband support blocks 130 can be two. When the two headband support blocks 130 are in close contact, a headband in an arc structure is formed. Specifically, each headband support block 130 can be, for example, a half-arc structure.

[0056] In some other embodiments, the number of the headband support blocks 130 can be greater than two. Chamfer designs can be provided on both sides of the headband support blocks 130. In one example, such as Figure 3As shown, the longitudinal section of the headband support block 130 can be an inverted trapezoid. After multiple headband support blocks 130 are in close contact, every two headband support blocks 130 are connected together at a set angle θ after being tractioned by a cable, forming a headband with an arc-shaped structure. In this example, the set angle θ can be the angle between the geometric center of each headband support block 130 and the connection line of the midpoints of the left main body 110 and the right main body 120, and this angle can be 10 degrees, for example.

[0057] The longitudinal section of the headband support block is the longitudinal section of the headband support block parallel to the extension direction of the cable. Taking the plane where the head-mounted device is located as the front view direction, this longitudinal section is the section corresponding to the front view of the support block.

[0058] In some embodiments, the surface of the headband support block 130 facing the head can be a flat surface or a curved surface.

[0059] In some embodiments, the head-mounted device 100 may further include a detection unit. The detection unit can be used to detect the mutual force between the headband support blocks 130. When the mutual force between the headband support blocks 130 reaches a preset value, multiple headband support blocks 130 are in close contact.

[0060] In one example, the detection unit can be composed of a strain sensor. Through this strain sensor, it can be detected whether the assembly between multiple headband support blocks 130 is in place. When the strain sensor detects that the strain force between the headband support blocks 130 reaches the preset value, it can be determined that multiple headband support blocks 130 are in close contact and the assembly is in place.

[0061] In one example, this strain sensor can be provided between every two headband support blocks 130. In another example, strain gauges can be installed near the contact surfaces of every two headband support blocks 130, and the contact strain force can be deduced by indirectly measuring the strain force.

[0062] In some embodiments, at least one of the left main body 110 and the right main body 120 may include a driving mechanism. The driving mechanism is connected to the cable 140 and is used to release or contract the cable 140. That is to say, driving mechanisms can be provided in both the left main body 110 and the right main body 120. When contracting or releasing the cable, the two driving mechanisms are controlled to work simultaneously; or a driving mechanism can be provided in one of the left main body 110 and the right main body 120, and when contracting or releasing the cable, the one driving mechanism is controlled to work.

[0063] In this embodiment, the driving mechanism is connected to the end of the cable 140. In one example, the driving mechanism may be a motor. When the state of the head-mounted device 100 is switched from the worn state to the stored state, the motor rotates in a first set direction (such as the clockwise direction), so that the cable 140 is released outward from at least one of the left main body 110 and the right main body 120. When the state of the head-mounted device 100 is switched from the stored state to the worn state, the motor rotates in a second set direction (such as the counterclockwise direction), so that the cable 140 contracts into at least one of the left main body 110 and the right main body 120. At this time, the motor can wind up the excess cable and contract it into at least one of the left main body 110 and the right main body 120. In this example, the driving mechanism may be disposed inside the left main body 110 or the right main body 120. In another example, the driving mechanism may also be an adjusting device for manually adjusting the cable, for example, a device for manually winding the cable. In this example, the driving mechanism may be disposed outside the left main body 110 or the right main body 120 so that the user can manually operate it.

[0064] In some embodiments, at least one of the left main body 110 and the right main body 120 may further include an internal control module. In one example, the internal control module may be a microprocessor, such as a single-chip microcomputer.

[0065] In one example, the internal control module may be used to receive an input switching signal and obtain the current state of the head-mounted device. When the current state of the head-mounted device is the worn state, control the head-mounted device to switch from the worn state to the stored state. When the current state of the head-mounted device is the stored state, control the head-mounted device to switch from the stored state to the worn state.

[0066] In another example, the internal control module may also be used to receive an input switching signal and determine the target switching state of the head-mounted device according to the switching signal. For example, when the switching signal indicates that the state of the head-mounted device is switched from the worn state to the stored state, control the state of the head-mounted device to be switched from the worn state to the stored state. When the switching signal indicates that the state of the head-mounted device is switched from the stored state to the worn state, control the state of the head-mounted device to be switched from the stored state to the worn state.

[0067] In some embodiments, at least one of the left main body 110 and the right main body 120 may further include an external control module. The external control module may be used to receive an operation of the user to switch the state of the head-mounted device and generate a level conversion signal.

[0068] In one example, such as Figure 3As shown, the left main body 110 includes a control button 111. The control button 111 can be long-pressed. After the user long-presses the control button 111, a level conversion signal is generated and a head-mounted device status switching signal is input to the internal control module.

[0069] In this example, the function of generating a level conversion signal by long-pressing the control button can be implemented through a switch circuit. For example, a pull-up resistor is connected between one end of the control button 111 and the power supply VCC, and the other end of the control button is grounded. When the control button 111 is not pressed, the GPIO (General Purpose Input Output) is connected to the power supply VCC through the pull-up resistor and reads a high level. When the control button is pressed, the GPIO is directly grounded and reads a low level. Another example is that a pull-down resistor is connected between one end of the control button 111 and the ground, and the other end of the control button 111 is connected to the power supply VCC. When the control button 111 is not pressed, the GPIO is grounded through the pull-down resistor and reads a low level. When the control button 111 is pressed, the GPIO is directly connected to the power supply VCC and reads a high level.

[0070] In another example, the control button 111 can be switched to different positions. When the user switches the control button 111 to different positions, different level conversion signals are generated correspondingly, so that the internal control module determines the target switching state of the head-mounted device according to different level conversion signals.

[0071] In this example, when the control button 111 is switched to the position corresponding to the wearing state, a first level conversion signal (such as a high-level signal) can be generated. When the internal control module receives this first level conversion signal, it determines that the target switching state of the head-mounted device is the wearing state. When the control button 111 is switched to the position corresponding to the storage state, a second level conversion signal (such as a low-level signal) can be generated. When the internal control module receives this second level conversion signal, it determines that the target switching state of the head-mounted device is the storage state.

[0072] The embodiment of the present application also provides a method for controlling a head-mounted device. This method is applied to the head-mounted device 100 in the above embodiment. As Figure 4 shown, this method may include step S110 to step S130.

[0073] Step S110, when receiving a switching signal for switching the state of the head-mounted device, obtain the current state of the head-mounted device.

[0074] In this embodiment, the switching signal can be received through GPIO. The switching signal can be a level change signal. In one example, the switching signal is a level change signal generated after the user long-presses the control button. When the user needs to switch the state of the head-mounted device, whether it is switched from the worn state to the storage state or from the storage state to the worn state, the user only needs to long-press the control button.

[0075] After receiving the switching signal, obtain the current state of the head-mounted device, and determine whether to switch to the worn state or the storage state according to the stored current state of the head-mounted device. If the current state of the head-mounted device is the worn state, then determine that it needs to be switched to the storage state. If the current state of the head-mounted device is the storage state, then determine that it needs to be switched to the worn state.

[0076] Step S120, when the current state of the head-mounted device is the worn state, control the cable to be released outward from at least one of the left main body and the right main body, so that the multiple headband support blocks spread out and switch to the storage state.

[0077] Step S130, when the current state of the head-mounted device is the storage state, control the cable to contract inward into at least one of the left main body and the right main body, so that the multiple headband support blocks are in close contact with each other to form the headband of the head-mounted device and switch to the worn state.

[0078] In the embodiment of the present application, after receiving the switching signal input by the user, according to the current state of the head-mounted device, control the cable to contract or release, so that the multiple headband support blocks are in close contact with each other or spread out, thereby realizing the switching of the user's wearing or storage requirements, and improving the user experience.

[0079] In some embodiments, step S120 may include: when the current state of the head-mounted device is the worn state, obtain the remaining length of the cable in at least one of the left main body and the right main body; when the remaining length is greater than the length threshold, control the cable to be released outward from at least one of the left main body and the right main body.

[0080] In one example, when the current state of the head-mounted device is the worn state, obtain the remaining length of the cable wound on the motor in at least one of the left main body and the right main body. When the remaining length is greater than the length threshold, control the motor to rotate in the first set direction to control the cable to be released outward from at least one of the left main body and the right main body.

[0081] In this embodiment, when the remaining length is less than or equal to the length threshold, stop controlling the cable to be released outward from the left main body and the right main body.

[0082] In some other embodiments, step S120 may include: when the current state of the head-mounted device is the worn state, obtaining the duration of the switching signal, and within this duration, controlling the cable to be released outward from at least one of the left main body and the right main body.

[0083] That is to say, when the current state of the head-mounted device is the worn state, when continuously receiving the switching signal, continuously control the cable to be released outward from at least one of the left main body and the right main body until the switching signal is interrupted, and stop controlling the cable to be released outward from at least one of the left main body and the right main body.

[0084] In one example, when the current state of the head-mounted device is the worn state, obtaining the duration of the switching signal, and within this duration, controlling the motor to rotate in a first set direction.

[0085] In some embodiments, step S130 may include: when the current state of the head-mounted device is the storage state, obtaining the interaction force between the headband support blocks; when this interaction force is less than a preset value, controlling the cable to contract inward into at least one of the left main body and the right main body.

[0086] In one example, when the current state of the head-mounted device is the storage state, obtaining the interaction force between the headband support blocks; when this interaction force is less than a preset value, controlling the motor to rotate in a second set direction to control the cable to contract inward into at least one of the left main body and the right main body.

[0087] In this embodiment, when the interaction force between the headband support blocks is greater than the preset value, stop controlling the cable to contract inward into at least one of the left main body and the right main body, so as to prevent over-rotation from damaging the head-mounted device.

[0088] In one example, when the interaction force between the headband support blocks is greater than the preset value, output an enable signal to the GPIO, and use this enable signal to control the motor to stop working.

[0089] In an embodiment where the external control module of the head-mounted device can input different switching signals for the worn state and the storage state, the head-mounted device control method of the embodiment of the present application may include step S210 to step S230.

[0090] Step S210, obtaining the switching signal of the state of the head-mounted device.

[0091] Step S220, when this switching signal indicates that the state of the head-mounted device switches from the worn state to the storage state, controlling the cable to be released outward from at least one of the left main body and the right main body, so that the plurality of headband support blocks spread apart.

[0092] Step S230: When the switching signal indicates that the state of the head-mounted device changes from the storage state to the wearing state, control the cable to contract inwardly into at least one of the left main body and the right main body, so that the plurality of headband support blocks are in close contact with each other to form the headband of the head-mounted device.

[0093] In this embodiment, the method for obtaining the switching signal of the state of the head-mounted device can refer to the description in the foregoing embodiments of this application, and will not be elaborated here.

[0105] These computer - readable program instructions can be provided to a processor of a general - purpose computer, a special - purpose computer, or other programmable data - processing apparatus to produce a machine such that, when the instructions are executed by the processor of the computer or other programmable data - processing apparatus, a device is produced that implements the functions / actions specified in one or more blocks of the flowchart and / or block diagram. These computer - readable program instructions can also be stored in a computer - readable storage medium, and these instructions cause a computer, a programmable data - processing apparatus, and / or other devices to operate in a specific manner. Thus, the computer - readable medium storing the instructions includes a manufactured article that includes instructions for implementing various aspects of the functions / actions specified in one or more blocks of the flowchart and / or block diagram.

[0106] Computer-readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device, causing a series of operational steps to be performed on the computer, other programmable data processing apparatus, or other device to produce a computer-implemented process such that the instructions executed on the computer, other programmable data processing apparatus, or other device implement the functions / acts specified in one or more blocks of the flowchart and / or block diagram.

[0107] The flowcharts and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present application. In this regard, each block in the flowchart or block diagram may represent a module, a segment of a program, or a portion of an instruction, which contains one or more executable instructions for implementing the specified logical function. In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the figures. For example, two consecutive blocks may in fact be executed substantially in parallel, or they may sometimes be executed in the reverse order, depending on the functions involved. It should also be noted that each block of the block diagrams and / or flowcharts, and combinations of blocks in the block diagrams and / or flowcharts, can be implemented by a dedicated hardware-based system that performs the specified functions or acts, or by a combination of dedicated hardware and computer instructions. It is well known to those skilled in the art that implementation by hardware, implementation by software, and implementation by a combination of software and hardware are equivalent.
