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. 1-4, comprising a headset body 2, an ear plug portion 4 and a control assembly 5; the earphone body 2 comprises a first cavity; the earplug part 4 comprises a second cavity, the earplug part 4 is made of an elastic material, and the second cavity is communicated with the first cavity to form an adjusting cavity; the control assembly 5 is used for controlling the air pressure in the adjusting cavity.

The first cavity and the second cavity are communicated to form an adjusting cavity which is an independent space. For example, by connecting the earplug portion 4 to the headphone body 1, the position of connection forms a seal.

When the earphone is worn, the earplug part 4 is placed in the ear canal, so that the ear insertion part 1 is matched with the ear of the user.

The independent space formed in the regulating cavity can control the air pressure in the regulating cavity through the control assembly 5. For example, the air pressure is adjusted to increase or decrease. The control unit 5 controls the air pressure in the chamber to expand the earplug section 4 in case the air pressure in the chamber increases. The control unit 5 controls the pressure in the chamber to be reduced, which causes the earplug section 4 to be contracted.

The air pressure in the chamber is controlled by the control assembly 5 to expand or contract the earplug section 4. Thereby adapt to different users' duct size, make portion 1 of going into the ear worn smoothly, can adapt to different users, improved user experience. And may also be adjusted during use by the control assembly 5 to adjust the size of the earplug section 4 to the appropriate condition.

The control unit 5 may control the air pressure in the adjustment chamber by filling or withdrawing air into or from the adjustment chamber.

The volume of the adjusting cavity formed by the communication of the first cavity and the second cavity is larger than that of the second cavity formed by only the earplug part. Under the condition that the same amount of gas is filled into the adjusting cavity, the expansion amount generated by the cavity with larger relative volume is smaller. This enables the degree of expansion of the earplug portion 4 to be adjusted more accurately.

In one embodiment, as shown in fig. 2, the control assembly 5 includes a housing 51 and a piston portion 52, the housing 51 forming a third chamber in communication with the regulating chamber, the piston portion 52 being disposed within the third chamber, the piston portion 52 moving along the third chamber to control the air pressure within the regulating chamber.

In this embodiment, the third chamber formed by the housing 51 communicates with the regulation chamber, and the piston portion 52 moves along the third chamber. By moving the piston portion 52, the total volume of the space in which the third chamber communicates with the adjustment chamber is reduced, and the air pressure is increased, so that the air pressure in the adjustment chamber is increased. By moving the piston portion 52, the total volume of the space in which the third chamber communicates with the adjustment chamber is increased, and the air pressure is decreased, so that the air pressure in the adjustment chamber is decreased.

The piston portion 52 moves within the third chamber to increase or decrease the air pressure within the adjustment chamber, thereby expanding or contracting the adjustment ear plug portion 4.

In one embodiment, the control assembly 5 further comprises a support portion 53 and a paddle 54, the support portion 53 being connected with the piston portion 52, the paddle 54 being connected with the support portion 53; the second pipeline section is provided with an avoiding hole, the avoiding hole is a strip-shaped hole, the strip-shaped hole extends along the direction in which the piston part 52 moves, and at least part of the structure of the shifting piece 54 extends out of the avoiding hole.

In this embodiment, the shifting piece 54 is connected to the piston portion 52 through the supporting portion 53, and the piston portion 52 can be driven to move along the first pipe section by moving the shifting piece 54, so as to control the air pressure in the adjusting chamber. Part of the structure of the poking sheet 54 extends out of the avoidance hole, so that the part of the structure is positioned outside the shell 51, and under the condition that the air pressure in the adjusting cavity needs to be controlled, the poking sheet 54 is poked from the outside of the shell 51 to control the piston part 52 to move.

As shown in fig. 3 and 4, fig. 3 shows a state in which the piston portion 52 is moved to the first position, and fig. 4 shows a state in which the piston portion 52 is moved to the second position. In the case where it is necessary to control the increase of the gas pressure in the adjustment chamber, the piston portion 52 is moved in the direction from the second position to the first position to compress the gas in the portion of the third chamber communicating with the adjustment chamber into the adjustment chamber, thereby increasing the gas pressure in the adjustment chamber. In the case where it is necessary to control the reduction of the gas pressure in the regulation chamber, the piston portion 52 is moved in the direction from the first position to the second position to transfer the gas in the regulation chamber to the portion of the third chamber communicating with the regulation chamber, thereby reducing the gas pressure in the regulation chamber.

In the process of moving the piston portion 52, the toggle shifting piece 54 moves from the side where the first position is located to the side where the second position is located, so that the air pressure in the adjusting cavity can be reduced, and the toggle shifting piece 54 moves from the side where the second position is located to the side where the first position is located, so that the air pressure in the adjusting cavity can be increased.

The movement of the shifting piece 54 can be limited within the range of the second pipe section, and the movement of the piston part 52 is limited within the range of the first pipe section, so that air leakage caused by the piston part 52 moving to the position of the avoidance hole is avoided. The condition that the air pressure in the adjusting cavity cannot be adjusted is avoided.

Optionally, a first limiting member is disposed in the first pipe segment or the second pipe segment, and the first limiting member limits the piston portion 52 from moving from the first pipe segment to the second pipe segment, so as to improve the sealing property in the space where the first pipe segment is communicated with the adjustment cavity and avoid air leakage.

Optionally, a plurality of second limiting members are disposed in the avoiding hole, the second limiting members can form a set resistance to the movement of the supporting portion 53 and the shifting piece 54, and when a set external force is applied to the shifting piece 54, the shifting piece 54 and the supporting portion 53 can offset the resistance corresponding to the second limiting members to move. When the piston portion 52 moves to the predetermined position, the second stopper can position the piston portion 52 by the stopper support portion 53 or the paddle 54, so that the piston portion 54 is held at the predetermined position, thereby keeping the air pressure in the adjustment chamber constant.

In one embodiment, the second tube section is provided with a pressure relief vent 55.
