Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The technical solution of the embodiment of the present application may be applied to earphones of various forms, for example, in-ear earphones or ear plugs, but the embodiment of the present application is not limited thereto.
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, which may also be referred to as a pressure-capacitance sensor, has the principle as shown in fig. 1, that when pressure is applied to the plate 12, the pressure causes the distance between the capacitors 21 between the two plates 11 and 12 to change, thereby changing the value of the capacitance. The pressure of different sizes produces different capacitance value changes, converts the change volume of this capacitance value into the electrical signal, measures the change of this signal through detecting the chip and can detect the size of corresponding pressure.
The resistance-type pressure sensor can also be called a piezoresistive sensor, and the principle of the resistance-type pressure sensor is as shown in fig. 2, the resistance-type pressure sensor 22 is arranged on a certain to-be-detected stressed surface, and the stressed carrier 13 is stressed to deform, so as to press or stretch the resistance-type pressure sensor 22, and accordingly the resistance value of the resistance-type pressure sensor changes accordingly. Different pressure size produces different resistance changes, detects this resistance change through detecting the chip and can detect corresponding dynamics size.
As shown in fig. 3, four independent resistive pressure sensors are combined into a bridge topology, i.e., a bridge resistive pressure sensor is formed, which can realize temperature drift suppression at a hardware level.
Fig. 4 shows a schematic block diagram of a headset 400 of an embodiment of the application.
As shown in fig. 4, the headset 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 may include:
a first set of pressure sensors comprising one or more pressure sensors, a pressure sensor of the first set of pressure sensors being disposed in an in-ear region of the earpiece.
The pressure sensor 410 may be a capacitive pressure sensor or a resistive pressure sensor, which is not limited in this application.

Optionally, the wearing state of the headset may include that the headset is not worn, the headset is worn into the ear, the headset is taken out of the ear, whether the headset is worn well (for example, wearing level) when the headset is worn, and the like, but the embodiment of the present application is not limited thereto.
Alternatively, the processing unit 420 may be specifically a processor, a processing chip or a detection chip.
The pressure sensor arranged in the ear-entering area can be used for detecting the pressure signal in the process of the earphone entering or exiting the ear. Deformation generated when the earphone is worn into the ear is conducted to the pressure sensor in the ear entering area step by step through the earphone structure, the deformation generated by pressure can be maintained all the time after the earphone is worn into the ear, and the pressure sensor also keeps corresponding signal quantity to finish in-ear wearing detection; when the earphone is out of the ear, the deformation can be restored, the pressure sensor in the ear area can correspondingly release the signal quantity, and the detection of the out-of-the-ear is finished.
In the embodiment of the application, the wearing state of the earphone is determined according to the pressure signal of the pressure sensor in the ear entering area of the earphone, so that corresponding operation can be executed corresponding to the wearing state of the earphone, manual control of a user is not needed, and user experience can be improved.

By arranging at least one pressure sensor in different areas, multi-dimensional pressure signals can be obtained, so that the accuracy of determining the wearing state of the headset can be improved. Furthermore, various operations can be realized according to signals of at least one pressure sensor, and user experience is further improved.
Alternatively, in one embodiment of the present application, the pressure sensor 410 may be disposed at multiple locations in the in-ear region of the earphone. For example, the pressure sensor 410 may be provided at an ear plug, a headphone post, or a headphone barrel of the in-ear region of the headphone.
As shown in fig. 5a, 6a and 7a, for an in-ear headphone, the pressure sensor 410 may be provided at an ear plug 510, a headphone post 520 or a headphone barrel 530 at the in-ear region of the headphone.
Alternatively, the pressure sensor 410 may be arranged on a deformation enhancing structure of the in-ear region of the earphone. For example, as shown in fig. 6b and 6c, a convex strip 521 or a concave groove 522 may be disposed on the concave portion of the earphone post 520, and then the pressure sensor 410 is attached with an adhesive 610 having a large deformation, such as foam cotton, so that the deformation may be structurally amplified to enable the pressure sensor to obtain a larger signal amount, thereby optimizing performance.
As shown in fig. 8a, for an earbud headphone (which may also be referred to as an earbud), the pressure sensor 410 may be located at an earbud 810 of the in-ear region of the headphone.
Optionally, in an embodiment of the present application, the at least one pressure sensor 410 further includes:
a second set of pressure sensors comprising one or more pressure sensors, a pressure sensor of the second set of pressure sensors being disposed in a hand-held area of the headset.
Another area where the pressure sensor 410 is located may be a hand-held area of the headset. For example, the pressure sensor 410 may be disposed at a headset sleeve of a handheld region of a headset.
As shown in fig. 5b, 6d and 7b, for an in-ear headphone, the pressure sensor 410 may be provided at the headphone sleeve 540 of the handheld area of the headphone.
As shown in fig. 8b, for an ear bud headphone, the pressure sensor 410 may be located at the headphone sleeve 840 in the hand-held area of the headphone.
Alternatively, in one embodiment of the present application, the pressure sensor 410 may be disposed on an inner side of the housing structure of the headset, on an outer side of the housing structure of the headset, or in the material of the housing structure of the headset.
For example, for the hand-held area, as shown in fig. 9, the pressure sensor 410 may be attached to the inner side of the housing structure of the earphone sleeve by an adhesive 910 (e.g., foam), or the pressure sensor 410 may be disposed in the material of the housing structure of the earphone sleeve by injection molding or the like, or the pressure sensor 410 may be directly printed or attached to the outer side of the housing structure of the earphone sleeve by an adhesive.
Similarly, for the ear entry area, as shown in fig. 10, the pressure sensor 410 may be attached to the inner side of the shell structure of the earplug, the earpiece post or the earpiece barrel by means of an adhesive 910, or the pressure sensor 410 may be disposed in the material of the shell structure of the earplug, the earpiece post or the earpiece barrel by means of injection molding or the like, or the pressure sensor 410 may be printed directly or attached to the outer side of the shell structure of the earplug, the earpiece post or the earpiece barrel by means of an adhesive.
For the pressure sensor in the handheld area, when external handheld force is applied, pressure is transmitted to the pressure sensor, and a corresponding pressure signal can be obtained.
For the pressure sensor in the ear-entering area, when the earplug is inserted into the ear, pressure is generated and transmitted to the pressure sensor, and a corresponding pressure signal can be obtained.
It should be understood that the pressure sensor 410 may be disposed in other areas of the earphone besides the ear insertion area and the hand holding area, which is not limited in the embodiments of the present application.
Alternatively, in one embodiment of the present application, a plurality of pressure sensors 410 may be provided for one area. For example, as shown in fig. 11 and 12, a plurality of pressure sensors 410 may be provided in the hand-held region (fig. 11) and the ear-entry region (fig. 12).
Alternatively, in one embodiment of the present application, three pressure sensors 410 of the same area may be provided on the inner side of the housing structure of the headset, on the outer side of the housing structure of the headset and in the material of the housing structure of the headset, respectively, as shown in fig. 13 (hand-held area) and fig. 14 (in-ear area). The three sensors form a multi-lamination sensing structure to form a triple pressure sensor, and a pressure signal with higher dimensionality can be acquired. In addition to the improvement of the accuracy of determining the wearing state of the headphone, operations such as tapping, pressing, shaking (shaking) and the like can be realized.
Alternatively, in one embodiment of the present application, a plurality of triplex pressure sensors in different locations may form a pressure sensing network system. For example, fig. 15 shows an eight-unit sensor network system composed of a plurality of triple pressure sensors, which is configured to arrange eight triple pressure sensors at eight positions in an ear area, obtain multi-dimensional pressure information at different positions to form the pressure sensor network system, and expand richer applications after signals of the pressure sensor network system are processed by a software algorithm of a processing unit.
Optionally, in an embodiment of the present application, the first set of pressure sensors includes a resistive pressure sensor of a bridge structure, where resistances of two adjacent bridge arms in a bridge in the resistive pressure sensor of the bridge structure are disposed on different sides of a housing structure of the earphone.
For example, as shown in FIG. 16, pressure sensor 410 is a resistive pressure sensor in a bridge configuration, and is composed of resistors 41,42,43, and 44 of four bridge arms, wherein resistor 41 is connected in series with resistor 44, and resistor 42 is connected in series with resistor 43. When placed on the earpiece post of the headset, resistors 41 and 43 are on the outside and resistors 42 and 44 are on the inside. Fig. 16 is a schematic diagram of the pressure sensor after being unfolded around the earphone post. When the earphone silica gel is sleeved in the ear to squeeze the piezoresistive sensor wrapping the whole earphone post, the resistance 41 and the resistance 43 positioned on the outer side and the resistance 42 and the resistance 43 positioned on the inner side are deformed in opposite directions under stress, so that the change directions of the resistances are opposite. It can be seen from the circuit diagram IN fig. 16 that when the resistances of two different planes are changed oppositely, the voltages IN + and IN-can obtain the largest input differential signal, and the optimal performance is achieved.
In another example, as shown in fig. 17, the pressure sensor 410 disposed on the earphone barrel of the earphone has a circular arc-shaped profile. Resistors 41 and 43 are located on the outside and resistors 42 and 44 are located on the inside. Similarly, when the earphone silicone is inserted into the ear, the resistance 41 and the resistance 43 located outside are deformed in the opposite direction to the resistance 42 and the resistance 43 located inside, and thus the resistance changes in the opposite direction. It can be seen from the circuit diagram IN fig. 17 that when the resistances of two different planes are changed oppositely, the voltages IN + and IN-can obtain the largest input differential signal, and the optimal performance is achieved.
Optionally, in an embodiment of the present application, if one or more pressure sensors in the first set of pressure sensors do not acquire a pressure signal, it is determined that the headset is not worn.

Alternatively, as shown in fig. 19, if the pressure sensors 410 are disposed in other regions, the pressure signals of the pressure sensors 410 in each region are jointly transmitted to the processing unit 420, so as to further improve the accuracy of the processing unit 420 in determining whether the earphone is worn or not.
Alternatively, as shown in fig. 20, if a plurality of pressure sensors 410 are provided for each area, and the pressure signals of the pressure sensors 410 of the respective areas are jointly transmitted to the processing unit 420, the processing unit 420 can determine whether the headset is worn or not through a software algorithm. In addition, the processing unit 420 may also implement other functions, such as heart rate monitoring, step counting, etc., according to signals of multiple pressure sensors 410 in the same area, thereby further improving user experience. Optionally, the processing unit 420 may also implement other functions, such as heart rate monitoring, etc., in combination with signals of other sensors in the system, such as an acceleration sensor, so as to further enhance the user experience.
The pressure sensors 410 in the ear-entering area and the hand-held area respectively acquire a hand-held pressure signal and an ear-entering pressure signal when the earphone is worn, that is, acquire two-dimensional pressure signals, so that the wearing state of the earphone can be accurately determined.

For a capacitive sensor, as shown in fig. 25, when the headset is at some close distance near ear skin 2520, parasitic capacitance 2530 is caused to increase significantly; at this time, the capacitive sensor 2510 will obtain a sensing signal to the processing unit, and the processing unit performs recognition through a software algorithm to complete the functions of wearing detection and the like.
Multiple sensing technologies may be used in combination, for example, one may be the primary sensing technology and the other may be the secondary sensing technology. That is to say, the piezoresistive sensing technology in the embodiment of the present invention can be applied not only to an earphone for pressure detection as a main sensing technology, but also to an earphone for infrared sensing or an earphone for capacitance sensing as an auxiliary sensing technology.
Alternatively, in one embodiment of the present application, as shown in FIG. 25, multiple pressure sensors 2550 may be disposed on the back side of the headset (finger 2540 touch position in FIG. 25). In one aspect, when finger 2540 touches this area, capacitive sensor 2510 is brought closer to skin 2520, creating a new key operation. On the other hand, with the multi-dimensional pressure effect of the multi-pressure sensor 2550, operations such as tapping, double-tapping, re-pressing, sliding and the like can be received, multi-dimensional sensing signals are acquired through the multi-pressure sensor 2550, so that a post-stage processing unit identifies the multi-dimensional sensing signals through a software algorithm, and finally different key functions can be realized.
Optionally, in an embodiment of the present application, as shown in fig. 26, a silicone sleeve 2610 in the earphone is a conductive silicone, and the silicone can be arranged into a capacitive sensor, so that a capacitance value contacting with skin can be increased to correspondingly increase the sensitivity of the capacitive sensor.
