It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. The objects distinguished by "first", "second", and the like are usually a class, and the number of the objects is not limited, and for example, the first object may be one or a plurality of objects. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The following describes the earphone provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

In one embodiment of the present application, there is provided a headset, as shown in fig. 1, including: the earphone comprises a shell 1, wherein the shell 1 is used for bearing components in the earphone; an airbag section 2 is provided outside the housing 1, and the airbag section 2 forms a cavity. One air bag portion 2 may be disposed outside the housing 1, or a plurality of air bag portions 2 may be disposed outside the housing 1, and the plurality of air bag portions 2 may be arranged and distributed according to actual requirements.

The earphone is further provided with an adjusting device, the adjusting device is arranged on the shell 1, and the adjusting device is borne by the shell 1. The adjusting means is used to adjust the air pressure within the cavity to inflate or deflate the air bag portion 2. The adjustment means increases the air pressure within the chamber to inflate the air-bag portion 2 and decreases the air pressure within the chamber to deflate the air-bag portion 2. The way in which the adjustment device adjusts the air pressure within the cavity may be that the adjustment device changes the air pressure within the cavity by inflating or extracting air from the cavity. The adjusting device can be arranged inside the housing 1, or outside the housing 1, and the specific position can be adjusted by those skilled in the art according to actual needs.

The air bag part 2 can be made of elastic material, and when the air pressure in the cavity changes, the air bag part 2 made of the elastic material expands or contracts according to the difference between the air pressure in the cavity and the air pressure outside the cavity. When the adjusting device adjusts the air pressure in the cavity to increase, the elastic material of the air bag part 2 stretches, thereby achieving the effect of expansion. When the adjusting device adjusts the air pressure in the cavity to be reduced, the elastic material of the air bag part 2 contracts, so that the effect of contracting the air bag part 2 is achieved.

In this embodiment, after the user wears the earphone to the ear position, the air bag portion 2 is opposed to the corresponding ear contour position for fixing the earphone. Specifically, it may be that the balloon portion 2 is positioned opposite to the ear canal orifice of the user. Under the condition that the earphone is not matched with the outline size of the ear, the size of the air sac part 2 is adjusted through the adjusting device, so that the size of the earphone is satisfied for a user needing the earphone.

Under the condition that the position is less compared to user's ear wearing at the earphone size, increase the atmospheric pressure in the cavity through adjusting device, make gasbag portion 2 inflation to with the volume increase of earphone, thereby make the size of earphone satisfy user's demand. Under the great condition in earphone size compare in the position of wearing for the ear, reduce the atmospheric pressure in the cavity through adjusting device, make gasbag portion 2 shrink to reduce the volume of earphone, thereby make the size of earphone satisfy user's demand.

The expansion or contraction of the above-described air bag portion 2 can change the size of the wearing position of the earphone. The wearing position is a position where the user needs to contact with the ear of the user to clamp the earphone in the ear when wearing the earphone. Generally, an in-ear earphone will clamp a part of the structure of the earphone with the position of the ear canal opening of the user to achieve the effect of fixed wearing. The changed earphone size of the air bag portion 2 means the position. The earphone can adapt to different ears of different users, and the requirements of different users on the size of the wearing position of the earphone are met.

In one embodiment, as shown in fig. 3, the adjusting device comprises an adjusting tube 3 and a piston portion 4 disposed inside the adjusting tube 3, and the adjusting tube 3 is connected to the housing 1 such that the adjusting tube 3 is fixed to the housing 1. The piston part 4 divides the adjusting pipe 3 into a gas storage cavity and a communication cavity, the gas storage cavity is communicated with a cavity formed by the gas bag part and forms a sealed space, and the total gas volume in the gas storage cavity and the cavity is unchanged. The communicating cavity is communicated with the outside of the adjusting pipe 3, so that the communicating cavity is communicated with the atmosphere, and the air pressure in the communicating cavity is unchanged relative to the external air pressure. In the adjusting pipe 3, the piston part 4 can form a barrier to gas on both sides of the piston part 4, i.e. the spaces on both sides of the piston part 4 are not communicated.

The adjustment device further comprises a drive device, which is connected with the piston part 4. The drive means can drive the piston part 4 along said adjusting tube 3. The piston part 4 can change the volume occupied by the air storage cavity and the communication cavity in the adjusting pipe 3 by moving in the adjusting pipe 3. When the driving means drives the piston portion 4 to move to the side where the air reservoir is located, the volume of the air reservoir is reduced. Because the air storage cavity is communicated with the cavity and the total volume of the internal air is unchanged, the internal air pressure is increased, so that the air bag part 2 is expanded, and the volume of the earphone is increased. Under the condition that the driving device drives the piston part 4 to move to one side where the communicating cavity is located, the volume of the air storage cavity is increased, and the air pressure in the air storage cavity and the air pressure in the cavity are reduced, so that the air bag part 2 is contracted, and the volume of the earphone is reduced.

In this embodiment, the driving device drives the piston portion 4 to move, so as to expand or contract the air bag portion 2, thereby achieving the purpose of changing the size of the earphone. The earphone can meet the requirements of different users on the size of the earphone.

In one embodiment, as shown in fig. 4, the driving means comprises a first driving means 61 and a second driving means 62. The first driving device 61 is used for driving the piston portion 4 to move towards the first direction, and the first driving device 61 may be arranged at a side where the air storage cavity is located, i.e. a side corresponding to the first direction. When the piston portion 4 moves in the first direction, the volume of the air reservoir chamber decreases, and the airbag portion 2 inflates. The second driving means 62 is adapted to drive the piston portion 4 in the second direction. The second driving device 62 may be disposed on a side where the communication chamber is located, and on a side corresponding to the second direction. When the piston portion 4 moves in the second direction, the volume of the air reservoir chamber increases, and the bag portion 2 contracts.

The piston portion 4 is driven by the first driving means 61 and the second driving means 62 to move in the first direction or the second direction, and the first driving means 61 and the second driving means 62 each provide a driving force in only one direction. The function of the device is simplified, and the functional requirement of the driving device is reduced.

In one embodiment, as shown in fig. 3, the adjusting tube 3 further includes a first through hole 31 and a second through hole 32, and the air storage cavity is communicated with the cavity formed by the air bag portion through the first through hole 31. During the movement of the piston part 4, gas circulates between the gas storage chamber and the cavity through the first through hole 31. For example, when the piston portion 4 moves in the first direction to contract the air reservoir, a part of the compressed air in the air reservoir enters the air reservoir, thereby inflating the airbag portion 2.

The communicating chamber communicates with the outside of the adjusting tube 3 through the second through hole 32, and the space in the communicating chamber does not affect the change of the bag portion 2. In the process of moving the piston part 4, the air in the communicating cavity and the air outside the adjusting pipe 3 reach air pressure balance. Since the gas outside the regulating tube 3 is communicated with the atmosphere, the pressure inside the communicating chamber is kept the same as the atmospheric pressure.

In one embodiment, a third through hole is provided on the housing 1, the second through hole 32 being opposite to the third through hole. This allows the communication chamber to communicate with the internal space of the housing 1, and the internal space of the housing 1 is also communicated with the atmosphere, so that the pressure in the communication chamber is maintained at the atmospheric pressure.

In this embodiment, the second driving device 62 can be disposed inside the housing 1, which improves the safety of the second driving device 62 and does not influence the normal operation of the second driving device 62. The second pulling rope 621 passes through the communicating chamber and the third through hole to be connected with the second driving device 62. A second drive device 62 may also be provided within the communication chamber.

In one embodiment, as shown in fig. 4, the drive device further comprises a first traction rope 611 and a second traction rope 621. The driving means drives the piston part 4 to move by the first traction rope 611 and the second traction rope 621.

Specifically, the first driving device 61 is disposed in the cavity, one end of the first pulling rope 611 is connected to the first driving device 61, the other end of the first pulling rope 611 passes through the first through hole 31 to be connected to the piston portion 4, and the first driving device 61 drives the piston portion 4 to move in the first direction through the first pulling rope 611. When the first driving device 61 outputs power, the first traction rope 611 can be retracted, and the traction piston portion 4 moves toward the first driving device 61 along the adjustment pipe 3. The piston portion 4 reduces the volume in the air storage chamber during movement, so that the internal air pressure is increased, thereby inflating the air bag portion 2.

The second driving device 62 is disposed on the housing 1, one end of the second pulling rope 621 is connected to the second driving device 62, the other end of the second pulling rope 621 passes through the second through hole 32 to be connected to the piston portion 4, and the second driving device 62 drives the piston portion 4 to move in the second direction through the second pulling rope 621. When the second driving device 62 outputs power, the second traction rope 621 can be retracted, so that the traction piston part 4 moves along the adjusting pipe 3 to the second driving device 62. The piston portion 4 increases the volume of the air reservoir chamber during its movement, and the internal air pressure decreases, thereby contracting the bag portion 2.

In one embodiment, the first driving device 61 and the second driving device 62 are both motors. The cost of the motor is low, and the cost of the earphone can be reduced. Can choose for use micro motor, set up that micro headset can not occupy too much space, can not influence the setting of other parts in the earphone. The motor may wind the traction rope around the output shaft in the process of driving the first traction rope 611 or the second traction rope 621, thereby achieving the purpose of retracting the traction rope.

For example, during the contraction of the first traction rope 611, the first traction rope 611 is wound onto the output shaft of the motor, so that the first traction rope 611 drives the piston portion 4 to move. When the piston portion 4 needs to be moved toward the second traction rope 621 side, another motor is started to wind the second traction rope 621 around the output shaft of the other motor. The first pulling rope 611 wound on the motor at one end of the first pulling rope 611 is pulled by the piston part 4 to move, so that the first pulling rope 611 drives the output shaft of the motor to rotate in the direction opposite to the winding direction.

The output end of the first driving device 61 is provided with a first receiving groove, and a part of the first traction rope 611 is wound in the first receiving groove. The first driving unit 61 drives the output end to wind the first traction rope 611 into the first receiving groove, thereby driving the piston part 4 to move in the first direction

The output end of the second driving device 62 is provided with a second receiving groove, and a part of the second pulling rope 621 is wound around the second receiving groove. The second driving means 62 drives the output end to wind the second drawing string 621 into the second receiving groove, thereby driving the piston part 4 to move in the second direction.

The provision of the first storage groove enables the first traction rope 611 to be stably retracted, and improves the reliability of the first driving device 61 in driving the piston portion 4 to move in the first direction. Similarly, the provision of the second receiving groove improves the reliability with which the second driving device 62 drives the piston portion 4 to move in the second direction.

In one embodiment, as shown in fig. 3, the adjustment tube is a ring-shaped tube, inside which a partition 5 is arranged. At the position of the partition 5, the interior of the annular tube is not communicated. The space between the first side of the partition 5 and the piston part 4 forms an air reservoir and the space between the second side of the partition 5 and the piston part 4 forms a communication chamber.

The annular pipe can be sleeved outside the shell 1 and is conveniently fixed with the shell 1. And can make the outside of casing 1 form even height, wear with user's ear after can with appear too much gap, improved the leakproofness of earphone with the duct, reduced the influence of noise to the earphone.

In one embodiment, as shown in fig. 3, the adjusting device is provided with a first limiting member 71 and a second limiting member 72.

The first limiting member 71 is disposed in the air storage cavity, and the first through hole 31 is located between the first limiting member 71 and the separating member 5. In the process that the piston part 4 moves in the first direction, the first limiting member 71 can limit the position of the piston part 4, so that the piston part 4 is prevented from moving through the first through hole 31, the communicating cavity cannot be communicated with the cavity, and the total gas volume in the gas storage cavity and the cavity is ensured to be unchanged.

The second limiting member 72 is disposed in the communicating cavity, and the second through hole 32 is located between the second limiting member 72 and the partition 5. In the process that the piston part 4 moves in the second direction, the second limiting part 72 can limit the position where the piston part 4 moves, so that the piston part 4 is prevented from moving through the second through hole 32, the gas storage cavity cannot be communicated with the second through hole 32, and the total gas volume in the gas storage cavity and the cavity is ensured to be unchanged.

In this embodiment, the first limiting member 71 and the second limiting member 72 limit the movable position of the piston portion 4 in the adjusting tube 3, ensure the communication between the air storage chamber and the cavity and the constant total air volume in the air storage chamber and the cavity, so as to change the internal air pressure when the piston moves, and achieve the purpose of expanding or contracting the air bag portion 2.

In one embodiment, the first limiting member 71 and the second limiting member 72 are both ring-shaped structures. The annular structure can be attached and fixed in the adjusting pipe 3, and is convenient to set. The pull rope can pass through the middle part of the annular structure, and the limiting part cannot influence the pull piston part 4 of the pull rope.

The first and

second stoppers

71 and 72 may be other stopper structures capable of restricting the moving position of the piston portion 4. Can be a rod, a bulge and the like fixed in the adjusting pipe 3.

In one embodiment, a cavity is formed between the airbag portion 2 and the housing 1. The bag portion 2 may be a structure that wraps a part of the housing 1, and the edge of the bag portion 2 and the housing 1 are hermetically connected, thereby forming a cavity between the bag portion 2 and the housing 1. The air bag part 2 in the structure is integrated with the shell 1 and forms a cavity between the two, and the material of the air bag part 2 used for molding the cavity is reduced.

The cavity may be formed by the airbag portion 2 itself, and the airbag portion 2 is connected to the housing 1. Air bag portion 2 can be changed according to actual demand in this structure, more convenient dismantlement and equipment under the condition of air bag portion 2 is changed or is maintained in needs.

In one embodiment, as shown in fig. 2, the outer surface of the housing 1 forms an annular recess structure, and the air bag portion 2 is disposed in the annular recess structure. The housing 1 forms an annular recessed structure as a space for accommodating the bag portion 2, and the bag portion 2 does not protrude from the annular recessed structure when the bag portion 2 is contracted to a smaller volume. Under the condition that the user does not need the expansion of the air bag part 2 to change the size of the earphone, the air bag part 2 is contracted to the annular concave structure by contracting the air bag part 2, and the normal wearing and use of the earphone can not be influenced by the air bag part 2. Under the condition that the air bag part 2 is expanded and protrudes out of the annular concave structure, the annular concave structure can limit the air bag part 2, and the reliability of connection between the air bag part 2 and the earphone is improved.

In one embodiment, the headset further comprises communication means and control means. The control device is connected with a communication device, and the communication device is communicated with external equipment connected with the earphone. For example, the earphone is connected with a mobile phone, a tablet and other devices. The control device is connected with the adjusting device, the communication device sends an adjusting instruction to the control device after receiving the adjusting instruction sent by the external equipment, and the control device controls the adjusting device to change the air pressure in the cavity according to the instruction, so that the size of the earphone is adjusted.

For example, when the user sends an instruction to the earphone to increase the earphone through the external device, the control device controls the adjusting device to increase the air pressure in the cavity, so that the air bag part 2 is expanded to achieve the purpose of increasing.

When a user sends an instruction for reducing the earphone to the earphone through the external equipment, the control device controls the adjusting device to reduce the air pressure in the cavity, so that the air bag is contracted, and the aim of reducing is fulfilled.

The range of the earphone increasing or decreasing can be set on the external equipment, and when the earphone is increased to the maximum set value, the increasing instruction is not executed. When the earphone is reduced to the minimum set value, the reduction instruction is not executed.

For example, when the headset receives the command to increase the headset, the external device determines whether the headset has reached a maximum. If the earphone has reached the maximum, the instruction is not executed, and if the earphone has not reached the maximum, the first driving device 61 is started to control the piston part 4 to move towards the first direction so as to increase the air pressure in the cavity and expand the air bag part 2 to enlarge the earphone.

When the command received by the earphone is to reduce the earphone, the external equipment judges whether the earphone reaches the minimum. If the earphone has reached the minimum, the instruction is not executed, and if the earphone has not reached the minimum, the second driving device 62 is started to control the piston part to move towards the second direction, so as to reduce the air pressure in the cavity and achieve the purpose of contracting the air bag part to contract the earphone.
