For example, it may be a fixed connection, a detachable connection or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 2, the in-ear type earphone of the present embodiment includes an in-ear part 10 for insertion into an ear canal of a human body during wearing of the earphone, and a grip part 20 exposed to the human ear during the wearing. The ear insertion part 10 and the hand-held part 20 can be assembled together in a mode of independent processing and reconnection; or can be integrally formed into a whole; of course, the structure can also be designed in other suitable manners, and this embodiment is not limited to this.

In order to adapt the in-ear part 10 to the inner ear structure of different wearers after the earphone is worn, the present embodiment is preferably designed to be slightly smaller than the conventional size of the human ear canal when the outer size of the ear part 10 is designed, and then a balloon 30 is wrapped on the outside of the in-ear part 10. The air bag 30 may completely cover the entire ear insertion portion 10 of the earphone, or may partially cover the ear insertion portion 10.

Considering that the sound outlet hole 13 may be formed at the end 11 of the ear inlet 10, if the airbag 30 is designed to completely cover the ear inlet 10, the air outlet hole 13 is covered by the airbag 30, which may affect the sound outlet effect of the earphone. In view of this, in the present embodiment, when the airbag 30 is attached to the ear insertion portion 10 of the earphone, it is preferable that the end portion 11 of the ear insertion portion 10 is not covered by the case peripheral surface 12 of the ear insertion portion 10. The housing peripheral surface 12 is a housing in the ear insertion portion 10 between the end portion 11 and the handle portion 20, as shown in fig. 2.

In the present embodiment, the airbag 30 may cover only a part of the casing peripheral surface 12 of the ear insertion portion 10, or may cover the entire casing peripheral surface 12 of the ear insertion portion 10. In view of simplifying the manufacturing process, the present embodiment preferably designs the air bag 30 to completely cover the peripheral surface 12 of the housing of the earphone inserted into the ear 10 in the circumferential direction, i.e. to form a complete circle of cover, so that the ear canal of the wearer of the earphone can be more fully contacted with the inflated air bag 30, thereby reducing the risk of losing the earphone due to accidental dropping.

In a preferred embodiment, the air bag 30 is preferably made of a soft rubber material or sheepskin, so as to further improve the wearing comfort of the earphone.

In order to control the inflation and deflation of the air bag 30, a small air pump 40 is also provided on the earphone in this embodiment, as shown in fig. 2. The air pump 40 may be built in the earphone housing; an external earphone shell (i.e., installed outside the earphone shell) is also possible, and a separately designed accommodation chamber is provided for the external earphone shell. The accommodating chamber can be fixedly arranged or detachably arranged on the earphone shell.

In consideration of the overall aesthetic property of the earphone, the air pump 40 is preferably disposed in the earphone housing, for example, in the handheld portion 20 of the earphone and away from the position of the earphone insertion portion 10, so that the transmission of noise generated by the air pump 40 during operation to the ear of a person can be reduced, and the use experience of the earphone user can be improved.

In this embodiment, the air pump 40 includes two air ports, namely a first air port 41 and a second air port 42, which can be used as both an air inlet and an air outlet. The earphone housing is provided with a vent hole 21, preferably in the housing of the hand-held portion 20. The first air port 41 of the air pump 40 is connected to the air vent 21 through an air pipe 43, so that the air pump 40 can communicate with the outside atmosphere through the air vent 21. The second port 42 of the air pump 40 is connected to the air bag 30 via an air pipe 44 so that the air pump 40 can inflate the air bag 30 or pump the air in the air bag 30.

In order to accurately control the inflation and deflation processes of the air pump 40, the embodiment further provides a pressure sensor 51 on the earphone for detecting the air pressure in the air bag 30.

In this embodiment, the pressure sensor 51 may be disposed outside the casing peripheral surface 12 of the earphone ear inlet 10, i.e., in a sealed chamber enclosed by the air bag 30 and the casing peripheral surface 12 of the ear inlet 10. Of course, the pressure sensor 51 may also be disposed inside the casing peripheral surface 12 of the earphone ear insertion portion 10, and an opening is formed on the casing peripheral surface 12 of the earphone ear insertion portion 10, and the opening is preferably located opposite to the installation position of the pressure sensor 51, so that the gas in the airbag 30 can directly act on the pressure sensor 51 through the opening, thereby ensuring the accuracy of detecting the gas pressure in the airbag 30. At this time, the airbag 30 encloses a sealed chamber together with the case peripheral surface 12 of the ear insertion portion 10 and the pressure sensor 51.

Of course, the air bag 30 may be used alone to form a sealed air chamber, the pressure sensor 51 is disposed in the air bag 30, and the lead of the pressure sensor 51 is led out from the air bag 30 and connected to the earphone housing, so that the detection signal output by the pressure sensor 51 can be transmitted to the circuit board 50 disposed in the earphone housing, thereby achieving effective monitoring of the air pressure in the air bag 30.

In the present embodiment, a controller 55 is disposed on the circuit board 50 embedded in the earphone housing, as shown in fig. 3. After the earphone is inserted into the ear canal of the human body, the controller 55 first controls the air pump 40 to inflate the air bladder 30. At this time, the first port 41 of the air pump 40 serves as an air inlet to draw the atmospheric air from the outside, and the atmospheric air is discharged into the air bag 30 through the second port 42 of the air pump 40, which serves as an air outlet at this time, to inflate the air bag 30.

During inflation, the balloon 30 becomes progressively larger and conforms closely to the ear canal of the human body. At this time, the gas pressure in the balloon 30 is increased due to the restriction of the deformation of the balloon 30 by the human ear canal. The gas pressure in the airbag 30 is detected in real time by the pressure sensor 51 and fed back to the controller 55. When the controller 55 detects that the air pressure in the air bag 30 rises to a set threshold, the air pump 40 is controlled to be closed, and at the moment, the earphone is properly attached to the auditory canal of the human body, so that the wearing is comfortable.

The air pump 40 may be controlled by the controller 55 to draw air from the bladder 30 when the user removes the headset. At this time, the second port 42 of the air pump 40 is evacuated from the air bag 30 as an air inlet, and then discharged to the outside atmosphere through the first port 41 of the air pump 40, which is an air outlet at this time, to complete the air-bleeding process. The deflation process may be ended by using a preset deflation time, or the end time of the deflation process may be determined by using the internal pressure of the air bag detected by the pressure sensor 51, which is not limited in this embodiment.

In order to determine the specific starting moment of the air pump 40 for the air charging and discharging operation, the present embodiment proposes two preferable design solutions.

One is to configure the wearing detection module on the headset, automatically detect the wearing state of the headset by wearing the detection module, and send the detection result to the controller 55. When the controller 55 detects that the earphone is worn, the air pump 40 is activated to inflate the air bag 30. When the controller 55 detects that the earphone is removed, the air pump 40 is controlled to pump air to discharge the air in the air bag 30.

As a preferable design of the wearing detection module, as shown in fig. 2 and 3, in this embodiment, a three-axis acceleration sensor 52 and a proximity sensitive switch 53 are provided in the wearing detection module. The three-axis acceleration sensor 52 may be disposed in a housing of the earphone, for example, disposed on the circuit board 50 inside the earphone, for detecting a movement trace of the earphone and generating a detection signal to the controller 55. The controller 55 can recognize whether the wearing operation or the taking-off operation is currently performed by the user of the headset by analyzing the movement trace of the headset. The proximity sensing switch 53 may be an infrared sensing switch, and may be disposed on the earphone housing, for example, on the end 11 of the ear insertion portion 10 of the earphone, or may be disposed on the housing peripheral surface 12 of the ear insertion portion 10 at a position away from the air bag 30, so as to detect the proximity of the earphone to the ear canal of the human body.

When the controller 55 detects that the user of the earphone performs the wearing operation through the three-axis acceleration sensor 52 and detects that the earphone is very close to the ear canal of the human body through the proximity sensing switch 53, the air pump 40 is started to enter the inflation process. On the contrary, when the controller 55 detects that the earphone user performs the earphone removing operation through the three-axis acceleration sensor 52 and detects that the earphone is far away from the ear canal of the human body through the proximity sensing switch 53, the air pump 40 is started to enter the air bleeding process.

The wearing detection module is configured in the earphone, so that the automatic control of the air charging and discharging process of the air bag 30 can be realized. Of course, the wearing detection module may also adopt other existing circuit or structure designs, and the embodiment is not limited to the above examples.

Secondly, an air inflation/deflation button 54 is additionally provided on the casing of the earphone, and as shown in fig. 4 and 5, the button is preferably provided on the hand-held portion 20 of the earphone and connected to the controller 55.

The inflation/deflation button 54 may be a slide button, and when the controller 55 detects that the slide button 54 slides to an inflation gear, the air pump 40 is controlled to perform an inflation process; when the controller 55 detects that the slide button 54 slides to the deflation position, the air pump 40 is controlled to perform the deflation process.

Of course, the inflation/deflation button 54 may also be a conventional push button, which is pressed once to perform the inflation process, and then pressed again to perform the deflation process, and the process is cycled in sequence.

The in-ear earphone of this embodiment can make the earphone adapt to different users' inner ear structure through the gasbag that can fill the gassing of design on its income ear, satisfies all users and wears the demand of earphone comfortably.

It should be noted that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the present invention.
