The pressure sensor in the embodiment of the present application may be a capacitive pressure sensor or a resistive pressure sensor, but the embodiment of the present application is not limited thereto.

The capacitive pressure sensor may also be referred to as a pressure sensitive sensor. The principle is as shown in FIG. 1. When pressure is applied to the electrode plate 12, the pressure changes the spacing of the capacitors 21 between the two

plates

11 and 12 to change. The size of the capacitor value. Different sizes of pressures produce different capacitance value changes, and the amount of change in the capacitance value is converted into an electrical signal, and the magnitude of the corresponding pressure can be detected by detecting the change of the signal by the detecting chip.

The resistive pressure sensor can also be called a piezoresistive sensor. The principle is as shown in FIG. 2. The resistive pressure sensor 22 is arranged on a force surface to be tested, and the force bearing body 13 is deformed by force, thereby squeezing. The resistive pressure sensor 22 is pressed or stretched so that its resistance value changes accordingly. Different pressure levels produce different resistance changes, and the corresponding force magnitude can be detected by detecting the resistance change of the detection chip.

As shown in FIG. 3, four independent resistive pressure sensors are combined into a bridge topology to form a bridge-type resistive pressure sensor, which enables hardware-level temperature drift suppression.

FIG. 4 shows a schematic block diagram of an earphone 400 of an embodiment of the present application.

As shown in FIG. 4, the earphone 400 includes at least one pressure sensor 410 and a processing unit 420.

At least one pressure sensor 410 is used to acquire a pressure signal.

The at least one pressure sensor 410 can include:

a first set of pressure sensors, the first set of pressure sensors including one or more pressure sensors, the pressure sensors in the first set of pressure sensors being disposed in an ear region of the earphone.

The pressure sensor 410 can be a capacitive pressure sensor or a resistive pressure sensor, which is not limited in this embodiment of the present application.

The processing unit 420 is configured to determine a wearing state of the earphone according to the pressure signal.

Optionally, the wearing state of the earphone may include that the earphone is not worn, the earphone is worn in the ear, the earphone is picked up, the earphone is worn (eg, wearing level), etc., but the embodiment of the present application does not limited.

Optionally, the processing unit 420 may specifically be a processor, a processing chip, or a detection chip.

A pressure sensor in the ear area can be used to detect pressure signals during earing or earing.

The deformation caused by the pressure will be maintained after the earphone is worn into the ear, and the pressure sensor also maintains the corresponding signal amount to complete the in-ear wearing detection; When the earphone is out of the ear, the deformation will be restored, and the pressure sensor in the ear area will release the signal amount accordingly, and the ear detection will be completed.

Further, various operations can be implemented according to the signals of the at least one pressure sensor to further enhance the user experience.

Optionally, in one embodiment of the present application, the pressure sensor 410 may be disposed at a plurality of locations in the ear region of the earphone. For example, the pressure sensor 410 can be disposed at an earbud, earphone column, or earphone barrel in the ear region of the earphone.

As shown in Figures 5a, 6a and 7a, for an in-ear earphone, the pressure sensor 410 can be disposed at the earbud 510, earphone post 520 or earphone barrel 530 of the ear region of the earphone.

Alternatively, the pressure sensor 410 can be disposed on the deformation enhancing structure of the earphone region of the earphone. For example, as shown in FIGS. 6b and 6c, a structure such as a rib 521 or a groove 522 may be disposed on the groove portion of the earphone column 520, and the pressure sensor may be attached to the adhesive 610 having a large deformation such as foam rubber. 410, the structure can be enlarged and deformed to make the pressure sensor obtain a larger signal amount and optimize the performance.

a second set of pressure sensors, the second set of pressure sensors including one or more pressure sensors, wherein the pressure sensors in the second set of pressure sensors are disposed in a handheld area of the earphone area.

Another set area of the pressure sensor 410 can be a hand held area of the earphone. For example, the pressure sensor 410 can be disposed at the earphone sleeve of the handheld area of the earphone.

As shown in Figures 5b, 6d and 7b, for an in-ear earphone, the pressure sensor 410 can be disposed at the earphone sleeve 540 of the hand-held area of the earphone.

As shown in Figure 8b, for an earbud earphone, the pressure sensor 410 can be disposed at the earphone sleeve 840 of the handheld area of the earphone.

Alternatively, in one embodiment of the present application, the pressure sensor 410 may be disposed on the inner side of the outer casing structure of the earphone, on the outer side of the outer casing structure of the earphone, or in the material of the outer casing structure of the earphone.

For example, for the hand-held area, as shown in FIG. 9, the pressure sensor 410 may be attached to the inner side surface of the outer casing structure of the earphone sleeve by a bonding glue 910 (for example, foam rubber), or the pressure may be applied by injection molding or the like. The sensor 410 is disposed in the material of the outer casing structure of the earphone sleeve, or the pressure sensor 410 is printed directly or attached to the outer side of the outer casing structure of the earphone sleeve by a glue.

Similarly, for the in-ear area, as shown in FIG. 10, the pressure sensor 410 may be attached to the inner side of the outer structure of the earplug, the earphone column or the earphone barrel by the bonding glue 910, or the pressure sensor may be injected by injection molding or the like. The 410 is disposed in the material of the outer casing structure of the earplug, the earphone column or the earphone cylinder, or the pressure sensor 410 is directly printed or attached to the outer side surface of the outer casing structure of the earplug, the earphone column or the earphone cylinder by a bonding glue.

For the pressure sensor in the hand-held area, when a hand-held external force is applied, the pressure is transmitted to the pressure sensor, and a corresponding pressure signal can be obtained.

For the pressure sensor in the ear area, when the earplug is in the ear, pressure is generated and the pressure is transmitted to the pressure sensor, and the corresponding pressure signal can be obtained.

It should be understood that the pressure sensor 410 may be disposed in other areas of the earphone in addition to the above-mentioned ear area and the hand-held area, which is not limited by the embodiment of the present application.

Alternatively, in one embodiment of the present application, a plurality of pressure sensors 410 may be provided for one zone. For example, as shown in Figures 11 and 12, a plurality of pressure sensors 410 can be provided in the hand-held area (Figure 11) and the in-ear area (Figure 12).

Optionally, in one embodiment of the present application, three pressure sensors 410 in the same area may be respectively disposed on the inner side surface of the outer casing structure of the earphone, the outer side surface of the outer casing structure of the earphone, and the earphone. The material of the outer casing structure is shown in Figure 13 (handheld area) and Figure 14 (in-ear area). The three sensors form a multi-layered sensing structure that forms a triple pressure sensor for higher dimensional pressure signals. In addition to improving the accuracy of determining the wearing state of the earphone, operations such as light touch, light press, heavy press, shaking (shaking), and the like can be realized.

Optionally, in one embodiment of the present application, the triple pressure sensor at a plurality of different locations may form a pressure sensing network system. For example, FIG. 15 is an eight-element sensing network system composed of a plurality of triple-pressure sensors, which are configured to respectively arrange eight triple-pressure sensors at eight positions in the ear region to obtain multi-dimensional pressure information at different positions to form a pressure sensing network. The system can process the signal of the pressure sensing network system through the software algorithm of the processing unit to expand the richer application.

resistors

resistors

41 and 43 are located outside, and the

resistors

42 and 44 are located inside. The right side of Fig. 16 is a schematic view of the pressure sensor that is wound around the earphone column once. When the earphone silicone sleeve is pressed into the ear and the piezoresistive sensor of the entire earphone column is wrapped, the externally-received resistor 41 and the resistor 43 are opposite to the resistance 42 and the resistor 43 located on the inner side, so the direction of change of the resistance is also The opposite of. It can be seen from the circuit diagram in Fig. 16 that when the resistances of the two different faces are oppositely changed, the voltages IN+ and IN- can obtain the maximum input differential signal to achieve the optimal performance.

In another example, as shown in FIG. 17, the pressure sensor 410 disposed on the earphone barrel of the earphone has a circular arc shape. The

resistors

41 and 43 are located on the outside, and the

resistors

42 and 44 are located on the inside. Similarly, when the earphone silicone is placed in the ear, the externally-measured resistor 41 and the resistor 43 are opposite to the resistance 42 and the resistor 43 located on the inner side, and thus the direction of change of the resistance is also reversed. It can be seen from the circuit diagram in Fig. 17 that when the resistances of the two different faces are oppositely changed, the voltages IN+ and IN- can obtain the maximum input differential signal to achieve the optimal performance.
