Description

Technical Field

[0001] The present invention relates to an in-ear electronic device, and particularly to an in-ear electronic device capable of automatically adjusting its size. Background Art

[0002] With the development of technology, more and more wireless earphones have emerged on the market. Such earphones are small in size and light in weight, usually equipped with a charging case, and are convenient to carry. Such earphones are often worn in-ear. To increase wearing comfort and prevent dropping, the in-ear structure of the earphones usually comes with earphone silicone tips of various sizes for users to choose the appropriate size of silicone tips.

[0003] However, this requires providing silicone tips of various sizes, and users can only use one of them, resulting in waste of resources. At the same time, users may also choose an inappropriate size, which may cause it to be too tight when inserted, resulting in excessive pressure, causing fatigue in the ear canal and auricle after long-term wearing and causing discomfort. If it is too loose when inserted, the earphones may also fall off and be lost. Summary of the Invention

[0004] The present invention is directed to an in-ear electronic device that can automatically adjust its size.

[0005] An in-ear electronic device according to the present invention includes an in-ear module. The in-ear module includes an in-ear main body, an elastic cover, a telescopic structure, and a first pressure sensor. The elastic cover covers the in-ear main body. The telescopic structure is disposed between the in-ear main body and the elastic cover for adjusting the radial size of the elastic cover. The first pressure sensor is disposed inside the elastic cover and is electrically connected to the telescopic structure. The first pressure sensor is used to sense the radial pressure of the in-ear module. When the value of the radial pressure of the in-ear module sensed by the first pressure sensor is not within the preset range, the telescopic structure acts to adjust the radial size of the elastic cover.

[0006] In an embodiment according to the present invention, the preset range is greater than or equal to a first predetermined value and less than or equal to a second predetermined value, and the second predetermined value is greater than the first predetermined value.

[0007] In an embodiment according to the present invention, when the value of the radial pressure of the in-ear module sensed by the first pressure sensor is greater than the second predetermined value, the telescopic structure shortens to reduce the radial size of the elastic cover.

[0008] In an embodiment according to the present invention, when the value of the radial pressure of the in-ear module sensed by the first pressure sensor is less than the first predetermined value, the telescopic structure elongates to increase the radial size of the elastic cover.

[0009] In an embodiment according to the present invention, the telescopic structure includes an ultrasonic motor, which includes a stator and a rotor that moves relative to the stator. The stator includes a piezoelectric element and an oscillator. The rotor moves relative to the stator to adjust the radial dimension of the elastic cover.

[0010] In an embodiment according to the present invention, the in-ear electronic device further includes an ear-outer module rotatably disposed on the in-ear module, and the ear-outer module includes a housing, two second pressure sensors, and a rotating structure. The two second pressure sensors are disposed on opposite sides of the housing. The rotating structure is connected to the housing and the in-ear module and electrically connected to the two second pressure sensors. The rotating structure is used to allow the housing to rotate relative to the in-ear module. When the larger of the two pressure values sensed by the two second pressure sensors is less than a third predetermined value, the rotating structure drives the housing to rotate relative to the in-ear module, so that the ear-outer module rotates backward toward the back of the auricle. When the larger of the two pressure values sensed by the two second pressure sensors is greater than the third predetermined value, the rotating structure drives the housing to rotate relative to the in-ear module, so that the ear-outer module rotates forward toward the front of the auricle.

[0011] In an embodiment according to the present invention, the rotating structure includes a stepper motor, which includes a stator and a rotor. One of the stator and the rotor is connected to the ear-outer module, and the other is connected to the in-ear module.

[0012] In an embodiment according to the present invention, the rotating structure includes an annular ultrasonic motor, which includes an annular stator and an annular rotor. The annular stator includes a piezoelectric element and an elastic metal element.

[0013] In an embodiment according to the present invention, the ear-outer module includes a microprocessor and a battery electrically connected to the microprocessor. The battery is disposed in the housing, and the two second pressure sensors, the rotating structure, and the in-ear module are electrically connected to the microprocessor.

[0014] In an embodiment according to the present invention, the ear-outer module includes a microphone disposed in the housing and electrically connected to the microprocessor.

[0015] In an embodiment according to the present invention, the ear-outer module includes a wireless communication component disposed in the housing and electrically connected to the microprocessor.

[0016] In an embodiment according to the present invention, the in-ear electronic device further includes a microprocessor electrically connected to the first pressure sensor and the telescopic structure. The in-ear module includes a sound generating unit electrically connected to the microprocessor.

[0017] In an embodiment according to the present invention, the in-ear electronic device further includes a microprocessor and a third sensor. The microprocessor is electrically connected to the first pressure sensor, the telescopic structure, and the third sensor. The third sensor is used to sense whether the in-ear electronic device is worn in the ear.

[0018] In summary, the in-ear electronic device of the present invention can adjust the radial dimension of the elastic cover by disposing a telescopic structure between the in-ear main body and the elastic cover. When the value of the radial pressure sensed by the first pressure sensor for the in-ear module is not within the preset range, the telescopic structure operates to adjust the radial dimension of the elastic cover. That is to say, the in-ear electronic device can automatically adjust its dimension so that a moderate pressure can be maintained between the in-ear module and the ear canal, effectively improving the wearing comfort of the user.

[0059] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same component symbols are used in the drawings and the description to represent the same or similar parts.

[0060] Figure 1 It is a side view schematic diagram of an in-ear electronic device according to an embodiment of the present invention. Figure 2 is Figure 1 a front view schematic diagram of the in-ear module of the in-ear electronic device. Please refer to Figure 1 and Figure 2 In this embodiment, the in-ear electronic device 100 takes an in-ear headphone as an example. However, in other embodiments, the in-ear electronic device 100 can also be a hearing aid. The type of the in-ear electronic device 100 is not limited thereto.

[0061] In this embodiment, the in-ear electronic device 100 includes an in-ear module 110, and the in-ear module 110 is the part of the in-ear electronic device 100 that can be put into the ear. Although in Figure 2 the outer shape of the in-ear module 110 is circular, the in-ear module 110 can also be designed as a non-regular circle and designed according to the structure and angle of the outer ear of the human ear to reduce the pressure on the auricle. The outer shape of the in-ear module 110 is not limited thereto.

[0062] The in-ear module 110 includes an in-ear main body 111, an elastic cover 112, a telescopic structure 120 and a first pressure sensor 113. The in-ear main body 111 includes a sound generating unit 114. In this embodiment, the number of the telescopic structure 120 and the first pressure sensor 113 is four respectively, and they are arranged around the in-ear main body 111 (upper, lower, left and right sides). Of course, in other embodiments, the number and the arrangement position of the telescopic structure 120 and the first pressure sensor 113 are not limited thereto, and the designer can adjust according to the requirements. The elastic cover 112 covers the in-ear main body 111. The material of the elastic cover 112 is, for example, rubber or silica gel and has an expandable function. However, the material of the elastic cover 112 is not limited thereto.

[0063] The telescopic structure 120 is arranged between the in-ear main body 111 and the elastic cover 112. The telescopic structure 120 can expand outwards or contract inwards to adjust the radial dimension of the elastic cover 112. Figure 3 is Figure 1 a schematic diagram of the telescopic structure of the in-ear electronic device. Please refer to Figure 3 In this embodiment, the telescopic structure 120 takes an ultrasonic motor 121 as an example. However, in other embodiments, the type of the telescopic structure 120 is not limited thereto. The ultrasonic motor 121 utilizes the inverse piezoelectric effect of piezoelectric ceramics to convert electrical energy into mechanical vibration, and then converts the mechanical vibration into the rotation or linear motion of the motor through friction. The ultrasonic motor 121 generally operates at a frequency above 20KHz.

[0064] The ultrasonic motor 121 includes a stator 122 and a rotor 125 that moves relative to the stator 122. The stator 122 and the rotor 125 are in close contact. The stator 122 includes a piezoelectric member 123 and oscillators 124, 126. The piezoelectric member 123 can be a piezoelectric ceramic component, and the oscillators 124, 126 can be elastic metal structures. The rotor 125 is a metal component and can be a metal rod. In this embodiment, the rotor 125 can move linearly relative to the stator 122 to adjust the radial dimension of the elastic cover 112. When actuated, a certain high-frequency alternating voltage is applied to the piezoelectric member 123 of the stator 122, and the two oscillators 124, 126 will be excited to generate elastic deformation, so as to drive the rotor 125 to become a telescopic shaft and move linearly relative to the stator 122. Therefore, when the ultrasonic motor 121 is actuated, the rotor 125 moves to expand or contract the elastic cover 112, realizing the process of adjusting the wearing tightness.

[0065] The first pressure sensor 113 is disposed within the elastic cover 112 and is electrically connected to the telescopic structure 120. In this embodiment, the first pressure sensor 113 is disposed between the telescopic structure 120 and the elastic cover 112, and the first pressure sensor 113 moves along with the telescopic structure 120. The first pressure sensor 113 is used to sense the radial pressure of the earbud module 110.

[0066] When the value of the radial pressure of the earbud module 110 sensed by the first pressure sensor 113 is not within the preset range, the telescopic structure 120 acts to adjust the radial dimension of the elastic cover 112. The preset range is greater than or equal to a first predetermined value and less than or equal to a second predetermined value, and the second predetermined value is greater than the first predetermined value.

[0067] In this embodiment, after the earbud module 110 is inserted into the ear, when the value of the radial pressure of the earbud module 110 sensed by the first pressure sensor 113 is less than the first predetermined value, it means that the size of the earbud module 110 is too small, and the telescopic structure 120 will correspondingly elongate to increase the radial dimension of the elastic cover 112, thereby increasing the radial dimension of the earbud module 110.

[0068] Similarly, when the value of the radial pressure of the earbud module 110 sensed by the first pressure sensor 113 is greater than the second predetermined value, it means that the size of the earbud module 110 is too large, and the telescopic structure 120 will correspondingly shorten to reduce the radial dimension of the elastic cover 112, thereby reducing the radial dimension of the earbud module 110. The in-ear electronic device 100 adjusts the wearing tightness by adjusting the size of the earbud module 110, thereby adjusting the pressure of the earbud module 110 on the ear canal and avoiding user fatigue.

[0069] Figure 4 is Figure 1 The appearance diagram of the in-ear electronic device worn on the ear. Please refer to Figure 4, in this embodiment, the in-ear electronic device 100 further includes an outer-ear module 150, and the outer-ear module 150 can be electrically connected to the in-ear module 110 through a flexible circuit board. In one embodiment, the outer-ear module 150 can also be signal-connected to the in-ear module 110 in a wireless transmission manner. In this embodiment, the outer-ear module 150 is rotatably arranged on the in-ear module 110, and the outer-ear module 150 can be slightly rotated forward or backward of the auricle to adjust the pressure between the outer-ear module 150 and the auricle, thereby improving the wearing comfort.

[0070] Figure 5 is Figure 1 the electrical connection diagram of the electronic components of the in-ear electronic device. Please also refer to Figure 4 and Figure 5 , the outer-ear module 150 includes a housing 151 ( Figure 4 ), a microprocessor 170, a battery 154, two second pressure sensors 152, 153 and a rotating structure 160. The two second pressure sensors 152, 153, the rotating structure 160 and the first pressure sensor 113, the telescopic structure 120, and the sound generating unit 114 of the in-ear module 110 are electrically connected to the microprocessor 170. The battery 154 is arranged in the housing 151 to provide power for the in-ear electronic device 100 and can have a counterweight effect.

[0071] As Figure 4 shown, the two second pressure sensors 152, 153 are arranged on opposite sides of the housing 151, and which of the two second pressure sensors 152, 153 senses the pressure or has a larger pressure value can be used to identify whether the in-ear electronic device 100 is worn on the left ear or the right ear. The rotating structure 160 is connected to the housing 151 and the in-ear module 110 and is electrically connected to the two second pressure sensors 152, 153. The rotating structure 160 is used to allow the housing 151 to rotate relative to the in-ear module 110.

[0072] In this embodiment, when the larger of the two pressure values sensed by the two second pressure sensors 152, 153 is less than a third predetermined value, it means that the pressure between the outer-ear module 150 and the auricle is too small (too loose). Since the back of the auricle is more convex than the front, rotating the outer-ear module 150 backward will make the outer-ear module 150 fit more closely to the auricle, thereby increasing the pressure between the outer-ear module 150 and the auricle. Therefore, the rotating structure 160 drives the housing 151 to rotate relative to the in-ear module 110, so that the outer-ear module 150 rotates backward toward the auricle.

[0073] When the larger of the two pressure values sensed by the two second pressure sensors 152 and 153 is greater than a third predetermined value, it represents that the pressure between the outer ear module 150 and the auricle is too large (too tight). The rotating structure 160 drives the housing 151 to rotate relative to the in-ear module 110, so that the outer ear module 150 rotates forward towards the auricle, thereby reducing the pressure between the outer ear module 150 and the auricle.

[0074] In addition, when the user holds the outer ear module 150, pressure is exerted on the two second pressure sensors 152 and 153. Therefore, when both of the two second pressure sensors 152 and 153 detect pressure, it represents that the user picks up the outer ear module 150. If the in-ear module 110 was previously in a worn state, it represents that the user wants to take out the in-ear electronic device 100, so that the outer ear module 150 rotates forward relative to the in-ear module 110 towards the auricle to reduce the pressure of the outer ear module 150 on the auricle, facilitating the user to take it out.

[0075] In addition, as Figure 5 shown, in this embodiment, the outer ear module 150 may optionally include a microphone 155 and a wireless communication component 156, which are respectively disposed in the housing 151 and electrically connected to the microprocessor 170. The microphone 155 can be used for sound collection. The wireless communication component 156 is, for example, a Bluetooth component, but is not limited thereto. The in-ear electronic device 100 can be signal-connected to a host (such as a mobile phone or a computer) through the wireless communication component 156. For example, the third predetermined value can be modified and set through a host (such as a mobile phone or a computer) to adapt to the usage habits of different users.

[0076] In addition, when the pressure value detected by the first pressure sensor 113 becomes smaller without measuring the pressure sensed by the two second pressure sensors 152 and 153 at the same time, the microprocessor 170 will first instruct the telescopic structure to extend to expand the in-ear module 110, making the user feel tightened. Subsequently, if the pressure value detected by the first pressure sensor 113 still decreases to near 0, the microprocessor 170 will determine that the earphone has fallen (abnormally taken out), so it notifies the host through the wireless communication component 156, and the host starts a warning message, for example, in the form of sound vibration or light emission, to remind the user to prevent the in-ear electronic device 100 from being lost.

[0077] In addition, as Figure 5 can be seen, the in-ear module 110 includes a third sensor 115, and the third sensor 115 is electrically connected to the microprocessor 170. The third sensor 115 can be an optical sensor, a temperature sensor or a barometric pressure sensor, and is used to sense whether the in-ear electronic device 100 has been worn in the ear.

[0078] Figure 6A And Figure 6B is Figure 1Actuation schematic diagram of the rotation structure of the in-ear electronic device. Please refer to Figure 6A and Figure 6B , in this embodiment, the rotation structure 160 includes a stepper motor 161, which includes a stator 162 and a rotor 163. One of the stator 162 and the rotor 163 is connected to the earbud module 150 ( Figure 1 ), and the other is connected to the in-ear module 110 ( Figure 1 ). Based on the principle of electromagnetic induction, the stepper motor 161 changes the polarity of the magnetic field of the stator 162 by changing the direction of the current in the coil on the stator 162, thereby driving the rotor 163 to rotate in a specific direction in the magnetic field as shown in Figure 6A and Figure 6B .

[0079] In this embodiment, the stator 162 can be fixed in the earbud module 150, and the rotor 163 is fixed to the in-ear module 110. By changing the direction of the current in the coil on the stator 162, relative rotation between the two can be achieved. Since the in-ear module 110 is inserted into the ear canal, relatively speaking, the earbud module 150 is less restricted, so that the earbud module 150 rotates relative to the in-ear module 110 to achieve the effect of rotating towards the front or back side of the auricle.

[0080] Figure 7 is a schematic diagram of the rotation structure of the in-ear electronic device according to an embodiment of the present invention. Please refer to Figure 7 , in this embodiment, the rotation structure 160a includes a ring ultrasonic motor 164. The ring ultrasonic motor 164 includes a ring stator 165 and a ring rotor 168. The ring stator 165 includes a polarized piezoelectric element 166 (piezoelectric ceramic material) and an elastic metal member 167. The ring rotor 168 is a metal ring with a flange groove. The two surfaces of the ring stator 165 and the ring rotor 168 facing each other are smooth and coated with a wear-resistant coating. By applying a high-frequency electrical signal to the piezoelectric element 166, the surface of the elastic metal member 167 is caused to vibrate, thereby macroscopically driving the ring rotor 168 to rotate. The rotation direction is opposite to the propagation direction of the vibration wave. In addition, changing the voltage direction can achieve a change in the rotation direction. The ring ultrasonic motor 164 of this embodiment has the advantages of fast response speed, high angle control accuracy, not being affected by magnetic fields, power-off self-locking, and not requiring continuous power consumption. Of course, the types of the rotation structures 160 and 160a of the in-ear electronic device 100 are not limited to the above.

[0081] Figure 8 is a flowchart of the operation method of the in-ear electronic device according to an embodiment of the present invention. Please refer to Figure 8, The operation method 200 of the in-ear electronic device includes the following steps. First, in step 210, it is determined whether the in-ear electronic device 100 is worn in the ear through the third sensor 115. The third sensor 115 can be an optical sensor, a temperature sensor, or a barometric pressure sensor, and can transmit optical, temperature, or barometric pressure data to the microprocessor 170 for the microprocessor 170 to determine whether the in-ear electronic device 100 is worn in the ear.

[0082] If the result of step 210 is yes, then step 212 is performed to continuously detect the pressure value of the first pressure sensor 120 of the in-ear module 110, and step 220 is performed to compare the pressure value x measured by the first sensor with the preset range y. The preset range y is greater than or equal to the first predetermined value and less than or equal to the second predetermined value, and the second predetermined value is greater than the first predetermined value. If, as in step 222, x = y, that is, the pressure value x is within the preset range y, it means that the tightness of the in-ear module 110 in the ear canal is appropriate. If x < y, that is, the pressure value x is less than the first predetermined value, it means that the in-ear module 110 is too loose in the ear canal, and step 224 is performed to extend the telescopic structure 120 of the in-ear module 110 so that the elastic cover 112 expands and increases the radial dimension. If x > y, that is, the pressure value x is greater than the second predetermined value, it means that the in-ear module 110 is too tight in the ear canal, and step 226 is performed to shorten the telescopic structure 120 of the in-ear module 110 so that the elastic cover 112 shrinks and reduces the radial dimension.

[0083] Next, step 230 is performed to detect the pressure difference between the two second pressure sensors 152 and 153 of the out-of-ear module 150 to determine whether the in-ear electronic device 100 is worn on the left ear or the right ear. The larger of the pressure values measured by the two second pressure sensors 152 and 153 represents that this second pressure sensor is in contact with the auricle, and the microprocessor 170 can determine whether the in-ear electronic device 100 is worn on the left ear or the right ear based on this.

[0084] Then, step 240 is performed to compare the larger of the two pressure values p measured by the two second pressure sensors 152 and 153 with the third predetermined value q. If, as in step 242, p = q, it means that the pressure between the out-of-ear module 150 and the auricle is appropriate. If p < q, it means that the pressure between the out-of-ear module 150 and the auricle is too small, and then step 244 is performed to rotate the out-of-ear module 150 backward toward the auricle. If p > q, it means that the pressure between the out-of-ear module 150 and the auricle is too large, and then step 246 is performed to rotate the out-of-ear module 150 forward toward the auricle.

[0085] Next, step 248 is performed to continuously detect the pressure value of the first pressure sensor 120. Then, step 250 is performed to detect whether the two second pressure sensors 152 and 153 sense pressure simultaneously. If not, step 252 is performed to detect whether the first pressure sensor 120 senses a decrease in pressure. If so, as in step 254, an abnormal drop occurs and the user is notified. If not, return to step 212.

[0086] Next, if step 250 is yes, then step 256 is performed to detect that the two second pressure sensors 152 and 153 sense pressure simultaneously for several seconds, for example, 2 - 4 seconds. Then step 258 is performed to determine that the user wishes to remove the in-ear electronic device 100, and the telescopic structure 120 of the in-ear module 110 is shortened to the shortest. Then return to step 210.

[0087] Please see Figure 8 On the left side, if step 210 determines that the in-ear electronic device 100 is not worn in the ear, then step 260 is performed, the telescopic structure 120 of the in-ear module 110 is shortened to the shortest, and the rotating structure 160 of the out-of-ear module 150 also returns to the initial position. Then, step 262 is performed to detect the two second pressure sensors 152 and 153, and step 264 to determine whether the two second pressure sensors 152 and 153 sense pressure simultaneously. If so, step 266 is performed to determine that the in-ear electronic device 100 has been picked up by the user, and then return to step 210. If not, return to step 262.

[0088] In summary, the in-ear electronic device of the present invention can adjust the radial dimension of the elastic cover by arranging the telescopic structure between the in-ear main body and the elastic cover. When the value of the radial pressure sensed by the first pressure sensor of the in-ear module is not within the preset range, the telescopic structure acts to adjust the radial dimension of the elastic cover. Specifically, when the value of the radial pressure sensed by the first pressure sensor of the in-ear module is less than the first predetermined value, the telescopic structure elongates to increase the radial dimension of the elastic cover; when the value of the radial pressure sensed by the first pressure sensor of the in-ear module is greater than the second predetermined value, the telescopic structure shortens to reduce the radial dimension of the elastic cover. That is to say, the in-ear electronic device can automatically adjust the size so that a moderate pressure can be maintained between the in-ear module and the ear canal, effectively improving the wearing comfort of the user.
