Description

wireless earbuds

The present invention relates to a wireless earbud, and more particularly, to a wireless earbud capable of preventing malfunction caused by a user's unintentional touch.

Wireless earbuds refer to earbuds without wires. Since wireless earbuds do not have wires, they are not cumbersome, so the convenience and feeling of use are very good. There is no need to arrange wires and there is no risk of disconnection. This is a huge advantage, as the most common reason for changing wireless earbuds is disconnection. Therefore, wireless earbud users generally show high purchase satisfaction, and demand is increasing.

Unlike conventional earphones that receive power from an external device, wireless earbuds operate with a built-in rechargeable battery. Unlike general earphones, most wireless earbuds are used in conjunction with external devices (eg, smart phones, tablet PCs, smart watches, etc.) through Bluetooth pairing, and basic operations are performed on the wireless ibuds. It also has a microphone so you can talk without taking out your phone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detailed description of the present invention which follows refers to the accompanying drawings which illustrate, by way of illustration, specific embodiments in which the present invention may be practiced. These embodiments are described in sufficient detail to enable one skilled in the art to practice the present invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, specific shapes, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the present invention in connection with one embodiment. Additionally, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. Accordingly, the detailed description set forth below is not to be taken in a limiting sense, and the scope of the present invention, if properly described, is limited only by the appended claims, along with all equivalents as claimed by those claims. Like reference numbers in the drawings indicate the same or similar function throughout the various aspects.

Referring to FIG. 3 , the wireless earbud 100 according to an embodiment of the present invention may include a body 110 and an ear tip 150.

The body 110 has a spherical shape as a whole. Here, the sphere includes not only a geometrically perfect sphere, but also a closed surface having a spherical part and a sphere having a circular or elliptical cross section.

A speaker is mounted in the body 110, and a microphone and a voice pickup unit (VPU) may be additionally disposed.

The body 110 may include an extension 115 extending in one direction from one portion of the body 110 . An ear tip 150 made of an elastic material, for example, a silicone material, may be mounted at the end of the extension part 115 . The extension part 115 may be a passage for guiding sound waves generated from a speaker disposed inside the body 110 .

The body 110 includes at least one pressure sensing unit 170 capable of sensing external pressure (or force) in another part of the body 110 .

The pressure sensing unit 170 may have a shape different from that of the surface of the body 110 . For example, the surface of the body 110 may be configured as a curved surface, and at least a portion of the surface of the pressure sensing unit 170 may be configured as a flat surface. Since the pressure sensing unit 170 has a shape different from that of the surface of the body 110, the user can grasp the position of the pressure sensing unit 170 by touch without seeing it with the naked eye.

The pressure sensing unit 170 may be disposed at the edge of the spherical body 110 instead of at the center. When the pressure sensing unit 170 is placed in the center of the spherical body 110, the extension 115 and the ear tip 115 can further enter the user's ear due to an external force, causing foreign body sensation and discomfort to the user. can give Therefore, the pressure sensing unit 170 is preferably disposed on the edge of the spherical body 110 .

Meanwhile, the wireless earbud 100 according to an embodiment of the present invention may further include a controller (not shown) disposed inside the body 110. The control unit (not shown) may output a pressure value based on a signal sensed by the pressure sensing unit 170 and may perform a predetermined function based on the output pressure value.

In addition, the wireless earbuds 100 according to an embodiment of the present invention may further include a communication unit (not shown) disposed inside the body 110. It may be wirelessly connected to an external device through a communication unit (not shown). For example, the communication unit (not shown) may include a Bluetooth communication module.

4 is a view showing that the wireless earbuds 100 according to an embodiment of the present invention shown in FIG. 3 are mounted on the ears of the user U, and FIG. 5 is the wireless earbuds 100 shown in FIG. ) It is a cross-sectional view according to an example of the body 110.

Referring to FIGS. 3 to 5 , the pressure sensing unit 170 includes at least one pressure sensor 500 (F.S).

The pressure sensor 500 may be disposed on the body 110 to sense a first pressure (Force 1) applied from the outside. The pressure sensor 500 may be disposed adjacent to the inner surface of the body 110 or the inner surface of the body 100 .

The pressure sensor 500 may be made of a material whose electrical characteristics can be changed according to the first pressure (Force 1) from the outside.

For example, the pressure sensor 500 may be a capacitive pressure sensor. The capacitive pressure sensor may include at least two or more conductive electrodes spaced apart from each other to sense a change in capacitance according to a change in distance between the two conductive electrodes according to a first external pressure (Force 1). An air gap may be formed between the two conductive electrodes spaced apart from each other, or a predetermined elastic material may be disposed. A sensing method of the capacitive pressure sensor may be a self-capacitance method or a mutual capacitance method.

Alternatively, the pressure sensor 500 may be a resistive pressure sensor. For example, the pressure sensor 500 may be a strain gage. The strain gauge can sense the state and amount of deformation of the body 110 by the first pressure (Force 1) from the outside as a change in resistance.

Examples of the pressure sensor 500 are capacitive pressure sensors and resistive pressure sensors, but are not limited thereto. The pressure sensor 500 can use any method as long as the electrical characteristic value output by the first pressure (Force 1) from the outside can be changed.

The controller (not shown) may output a pressure value based on the signal sensed by the pressure sensor 500, determine whether the output pressure value is greater than or equal to a preset threshold value, and determine whether the output pressure value is greater than or equal to the threshold value if the output pressure value is greater than or equal to the threshold value. A predetermined function may be performed by recognizing the applied touch as a touch intended by the user. That is, the wireless earbuds can recognize a touch from the outside as a touch intended by the user only when the pressure value of the first pressure (Force 1) of the touch from the outside is equal to or greater than the threshold value. Through this, malfunction due to an unintentional touch can be prevented.

more pressure sensors

500a and 500b.

Referring to FIG. 6 , there may be two or more pressure sensors 500 of the wireless earbuds according to another embodiment of the present invention. For example, the pressure sensor 500 may include a first pressure sensor 500a and a second pressure sensor 500b.

The wireless earbuds according to another embodiment of the present invention shown in FIG. 6 can be operated by at least two pressures (Force 1 and Force 2). If at least two or more pressures (Force 1 and Force 2) are not sensed, the wireless earbuds according to another embodiment of the present invention may not be manipulated. Through this, it is possible to prevent malfunction of the wireless earbuds due to a user's unintentional touch.

The first and

second pressure sensors

500a and 500b may respectively sense first and second pressures Force 1 and Force 2 from the outside.

The first pressure sensor 500a and the second pressure sensor 500b may be the same pressure sensor, but are not limited thereto.

The first pressure sensor 500a and the second pressure sensor 500b may be different pressure sensors. The first pressure sensor 500a and the second pressure sensor 500b may have different structures or different methods. For example, the first and second pressure sensors 500a are capacitive pressure sensors, but the shapes or sizes of two or more conductive electrodes may be different from each other. Alternatively, the first pressure sensor 500a may be a capacitive pressure sensor, and the second pressure sensor 500b may be a resistive pressure sensor.

Also, the first and second pressure sensors 500a may have different pressure sensing sensitivities. For example, the pressure sensing sensitivity of any one of the first and

second pressure sensors

500a and 500b may be higher than that of the other one.

Positions of the first pressure sensor 500a and the second pressure sensor 500b may be respectively specified. The first pressure sensor 500a and the second pressure sensor 500b are disposed on the body 110, and the first pressure sensor 500a and the second pressure sensor 500b are arranged based on the center O of the body 110. It can be arranged so that the angle between them is 90 degrees or more and 180 degrees or less. This minimizes the entry of the extension 115 and the ear tip 150 of the body 110 shown in FIG. 3 into the user's ear by the first and second pressures (Force 1 and Force 2) applied from the outside, can reduce discomfort.

FIG. 7 is another exemplary view for explaining the positions of the first and

second pressure sensors

500a and 500b shown in FIG. 6 .

Alternatively, as shown in FIG. 7, the position of the first pressure sensor 500a and the second pressure sensor 500b is the first pressure (Force 1) from the first pressure sensor 500a toward the center O. So that the direction of the sum of the vector of and the vector of the second pressure (Force 2) from the second pressure sensor 500b toward the center O is deviated from the extension direction D 115 of the extension part ₁₁₅ shown in FIG. can be placed. This also minimizes the extension 115 of the body 110 shown in FIG. 3 and the ear tip 150 entering the user's ear by the first and second pressures (Force 1 and Force 2) applied from the outside. User discomfort can be reduced.

more pressure sensors

500a and 500b shown in FIG. 6 or 7 .

Referring to FIG. 8 , each of the first and

second pressure sensors

500a and 500b may include two conductive electrodes 550 spaced apart from each other and facing each other. Also, the two conductive electrodes 550 may have a shape corresponding to the inner or outer surface of the body 110 . For example, when the inner or outer surfaces of the body 110 are curved, the two conductive electrodes 550 may have a curved plate shape.

Meanwhile, as shown in FIG. 3 , when the pressure sensing unit 170 is flat, the conductive electrode 550 of each of the first and

second pressure sensors

500a and 500b may have a flat plate shape.

Alternatively, when the pressure sensing unit 170 corresponding to the first pressure sensor 500a has a flat surface and the pressure sensing unit corresponding to the second pressure sensor 500b has a curved surface, the first pressure sensor 500a The conductive electrode may have a flat plate shape, and the conductive electrode of the second pressure sensor 500b may have a curved plate shape. Of course, the opposite is also possible.

Referring to FIG. 9 , the first pressure sensor is located in the body of the wireless earbud 100 where the first pressure (Force 1) is applied, and the second pressure sensor is located in the body of the wireless earbud 100. When located at a part where pressure (Force 1) is applied, the user directly presses the place where the first pressure sensor 500a is located with one finger with the first pressure (Force 1), and the other finger presses the second pressure Two or more pressures may be applied to the wireless earbuds 100 by indirectly pressing the location where the sensor is located with the second pressure (Force 2) through the lobe of the ear (E).

The controller of the wireless earbud 100 senses two or more pressures, respectively, and recognizes two or more touches of the user as intended touches for performing a predetermined operation when the sensed pressure value is equal to or greater than a preset threshold value. .

On the other hand, the wireless earbud 100 receives two or more user's touches even when one of the two or more pressures is equal to or greater than a preset threshold and the other is a normal touch (tap touch) equal to or less than the threshold. It can be recognized as an operation for the functional operation of That is, the two or more pressures do not necessarily have to be equal to or greater than a predetermined threshold value.

Another example of FIG. 10 is that a user applies two or more pressures to the wireless earbuds 100 according to various embodiments of the present invention while wearing a general glove on their hands.

Since the wireless earbuds 100 according to various embodiments of the present invention use at least one pressure sensor, the user's pressure can be recognized even when the user wears a general glove. On the other hand, since the conventional wireless earbud 10 shown in FIG. 1 uses one touch pad, only a conductive object such as a finger can be recognized as a touch.

Referring to FIG. 11 , a wireless earbud 700 according to another embodiment of the present invention may include a body 710 and an ear tip 750.

The body 710 has a spherical shape as a whole. Here, the sphere includes not only a geometrically perfect sphere, but also a closed surface having a spherical part and a sphere having a circular or elliptical cross section.

A speaker is mounted in the body 710, and a microphone and a voice pickup unit (VPU) may be additionally disposed.

The body 710 may include an extension 715 extending in one direction from one portion of the body 710 . An ear tip 750 made of an elastic material, for example, a silicone material, may be mounted at the end of the extension part 715 . The extension 715 may be a passage for guiding sound waves generated from a speaker disposed inside the body 710 .

The body 710 includes at least two

touch pads

760a and 760b. The at least two

touch pads

760a and 760b may include a first touch pad 760a and a second touch pad 760b.

The wireless earbuds 700 according to another embodiment of the present invention may further include a controller (not shown) disposed inside the body 710. The controller (not shown) may recognize touch manipulation based on signals sensed by at least two or

more touch pads

760a and 760b, and may perform a predetermined function based on the recognized touch manipulation.

When a user's hand rubs the surface of the wireless earbuds 500, the rubbing motion is an unintended motion by the user. In order to prevent an erroneous touch operation of the wireless earbuds 500 due to the swiping operation, the controller receives signals sensed from at least two or

more touch pads

760a and 760b, and touches the rubbing operation based on the received signals. It can be made not to be recognized as manipulation.

For example, the controller may output touch values from signals from at least two

touch pads

760a and 760b, and determine whether each

touch pad

760a and 760b is touched based on the output touch values. . At this time, the controller may determine whether the signals determined as touches are received simultaneously or with a predetermined time difference. As a result of the determination, if touch values of signals from at least two or

more touch pads

760a and 760b correspond to touches, and the signals are simultaneously received or received within the predetermined time difference, the user's touch manipulation is regarded as the user's intended touch. , and when the predetermined time difference is exceeded, the user's touch operation may be recognized as a touch not intended by the user. Since the swiping operation is an operation in which a time difference between signals sensed by at least two or

more touch pads

760a and 760b exceeds the predetermined time difference, the control unit of the wireless earbud 700 does not intend the swiping operation by the user. The user's touch operation may be rejected (or ignored) by recognizing it as an undesirable touch.

Meanwhile, the wireless earbud 700 according to another embodiment of the present invention may further include a communication unit (not shown) disposed inside the body 710. It may be wirelessly connected to an external device through a communication unit (not shown). For example, the communication unit (not shown) may include a Bluetooth communication module.

Referring to FIG. 12 , the modified embodiment of the wireless earbud 700 shown in FIG. 11 may include four

touch pads

760a, 760b, 760c, and 760d. Using the four

touch pads

760a, 760b, 760c, and 760d, various touches not intended by the user can be distinguished.

The controller of the wireless earbuds may receive signals received from the four

touch pads

760a, 760b, 760c, and 760d, and determine whether the user's touch is an intended touch or not based on the received signals. For example, the controller outputs touch values from signals received from the four

touch pads

760a, 760b, 760c, and 760d, and outputs touch values to each of the

touch pads

760a, 760b, 760c, and 760d based on the outputted touch values. It is possible to determine whether or not a touch has been made individually. Based on the number of

touchpads

760a, 760b, 760c, and 760d determined as touches or/and the time difference between

touchpads

760a, 760b, 760c, and 760d determined as touches, the controller determines whether the user's touch is intended. It is possible to determine whether or not the touch has occurred. As a more specific example, when the touch values of the signals received from the four

touchpads

760a, 760b, 760c, and 760d are all determined as touches, and all signals are received simultaneously or within a predetermined time difference, the user's touch operation may be determined as a touch intended by the user, and in the other cases, the user's touch operation may be determined as a touch not intended by the user, and the user's touch operation may be rejected (or ignored).

Meanwhile, in the wireless earbuds shown in FIGS. 11 and 12 , the touch sensitivity desired by the user may be adjusted using a plurality of touch pads. For example, when a plurality of touch pads are implemented in a self-capacitance method, since the self-capacitance method has relatively better touch sensitivity than the mutual capacitance method, a number of The touch sensitivity of the touch pads may be adjusted. For example, the user can adjust the sensitivity of a plurality of touch pads through a wireless earbud management application installed in the external device.

Referring to FIG. 13 , a wireless earbud 900 according to another embodiment of the present invention may include a body 910 and an ear tip 950.

The body 910 has a spherical shape as a whole. Here, the sphere includes not only a geometrically perfect sphere, but also a closed surface having a spherical part and a sphere having a circular or elliptical cross section.

A speaker is mounted in the body 910, and a microphone and a voice pickup unit (VPU) may be additionally disposed.

The body 910 may include an extension 915 extending in one direction from one portion of the body 910 . An ear tip 950 made of an elastic material, for example, a silicone material, may be mounted at the end of the extension part 915 . The extension 915 may be a passage for guiding sound waves generated from a speaker disposed inside the body 910 .

The body 910 includes at least one touch pad 960 capable of sensing a touch from the outside in another part of the body 910 .

The wireless earbud 900 according to another embodiment of the present invention may further include a communication unit (not shown) disposed inside the body 910 . It may be wirelessly connected to an external device through a communication unit (not shown). For example, the communication unit (not shown) may include a Bluetooth communication module.

In addition, the wireless earbud 900 according to another embodiment of the present invention may further include a controller (not shown) disposed inside the body 910.

The controller (not shown) may determine whether the user's touch manipulation is an intended touch based on two or more touches to the touchpad 960 .

For example, the controller may determine whether the user's touch manipulation is an intended touch based on the first touch and the second touch input to the touch pad 960 . The first touch is a touch input to the touch pad 960 temporally earlier than the second touch, and the second touch is a touch input immediately after the end of the first touch.

A first touch is a touch input to the touch pad 960 during a first time period, and a second touch is a touch input to the touch pad 960 during a second period of time. The first time is longer than the second time. The first time is a time longer than the reference time for distinguishing a tap touch and a long touch, and the second time is a time shorter than the reference time.

The control unit receives a signal sensed from the touchpad 960 by the user's initial touch, outputs an initial touch value from the received signal, and sets the touch threshold value from a time when the output initial touch value is equal to or greater than a preset touch threshold value. A time less than the first touch is measured, and if the measured time is greater than or equal to the reference time, the first touch of the user is determined as the first touch.

When the first touch is determined, the controller determines whether the user's next touch input after the user's first touch is the first touch or the second touch. The control unit receives a signal sensed from the touchpad 960 by the user's next touch, outputs a next touch value from the received signal, and sets the touch threshold value from a time when the output next touch value is equal to or greater than a preset touch threshold value. A time less than the reference time is measured, and if the measured time is greater than or equal to the reference time, the user's next touch is determined as the first touch, and if the measured time is less than the reference time, the user's next touch is determined as the second touch. determined by When the user's next touch is determined to be the second touch, the controller may perform a preset first function, and when the user's next touch is determined to be the first touch, the controller performs a function different from the first function. can do. Furthermore, the controller may perform functions different from the first function according to the number and/or type of the user's next touch.

For example, as shown in <Table 1> below, if a second touch is detected after the first touch, the first function, a music play or pause function, can be performed, and after the first touch, a second touch can be performed. When the second touch of the number is determined, the second function of playing the next song, answering a call, and ending a call may be performed. In addition, if three second touches are determined after the first touch, a third function, a previous song playback function, may be performed. And, if the first touch is determined again after the first touch, the fourth function, a preset function execution or call rejection, may be performed.

Meanwhile, as a result of determining the user's first touch, the control unit determines if the user's first touch does not satisfy the first touch, whether the user's next touch is the first touch or the second touch, the first touch and the next touch can be rejected (or ignored). Through this, the wireless earbuds can distinguish a user's unintentional touch, for example, the above-described rubbing motion, and the like, thereby preventing an erroneous operation.

In addition, if the first touch is determined as the first touch and the next touch is not the first and second touches, the controller determines that the user's first touch and the next touch are not the user's intended touches, and controls these touches. can be rejected (or ignored). Accordingly, the wireless earbuds can distinguish a touch that is not intended by the user, for example, the above-described rubbing motion, and the like, thereby preventing an erroneous operation.

The features, structures, effects, etc. described in the embodiments above are included in one embodiment of the present invention, and are not necessarily limited to only one embodiment.
