[0026] The following will describe Figure 1 - Figure 6 the earphone and the earphone device according to the embodiments of the present invention.
[0027] As shown in the figure, the earphone includes: an earphone main body 1 having a sound output part 11; an ear cap 2 sleeved on the sound output part 11, the ear cap 2 having a deformation part 21 for contacting the user's ear canal; a heating element 4 connected to the sound output part 11 and / or the ear cap 2, and when the heating element 4 is powered on, the deformation part 21 is heated to a first state; when the heating element 4 is powered off, the deformation part 21 returns to a second state, and the hardness of the deformation part 21 in the second state is greater than that in the first state.
[0028] In the embodiments of the present application, the ear cap 2 of the earphone has a deformation part 21 for contacting the user's ear canal, and the hardness of the deformation part 21 in the first state is greater than that in the second state. In this way, when the user is stationary, the heating element 4 can be controlled to be powered on to heat the deformation part 21 of the ear cap 2 to the first state, so that the deformation part 21 becomes softer, and the extrusion degree on the user's ear can be reduced, thereby solving the problem that the user's ear has a swelling pain after wearing the earphone for a long time.
[0029] In addition, when the user is walking, running or jumping, the heating element 4 can also be controlled to be powered off, so that the deformation part 21 returns to the second state and becomes harder, which can improve the tightness of the cooperation between the deformation part 21 and the user's ear canal, and can also solve the problems of the ear cap 2 making a shaking abnormal sound or even the earphone falling out of the user's ear canal.
[0030] In the embodiments of the present application, the fitting tightness between the ear cap 2 and the user's ear canal can be adjusted according to the user's usage scenario, so that the earphones in the embodiments of the present application can better meet the user's usage requirements.
[0031] The earphones described in the embodiments of the present application are in-ear earphones, applicable to wired earphones, which can directly transmit through a wire, achieve good sound quality, plug and play, and do not require charging. The earphones are also applicable to wireless earphones, which can be connected via Bluetooth, without cables, can avoid the problem of cable entanglement, and can implement additional functions such as noise reduction and touch operation. The wireless earphones can be mono Bluetooth earphones, stereo Bluetooth earphones, true wireless stereo earphones (True Wireless Stereo, TWS earphones), etc.
[0032] Specifically, taking wireless earphones as an example, the earphones include an earphone body 1, and the earphone body 1 may include components such as a driving unit, a battery, a charging interface, a microphone, a control button, a Bluetooth module, a sensor, a housing 12, etc. The housing 12 can be the main part of the earphone body 1, used for installing, arranging, and protecting components such as the driving unit, the battery, the charging interface, the microphone, the control button, and the Bluetooth module.
[0033] Specifically, the earphone body 1 has a sound outlet portion 11, and sound can be emitted from the sound outlet portion 11 and transmitted to the human ear. Among them, the sound outlet portion 11 can protrude from the housing 12, the ear cap 2 can be sleeved on the sound outlet portion 11, the ear cap 2 can contact the user's ear canal, and the ear cap 2 is inserted into the user's ear canal, so that the sound transmitted through the sound outlet portion 11 can reach the user's ear.
[0034] Specifically, the ear cap 2 may include a deformation portion 21. The deformation portion 21 may be made of thermoplastic elastomer (TPE), thermoplastic elastomer composite material, silicone, or silicone composite material, etc. The properties of these materials can change with temperature. They will become soft at higher temperatures and hard at lower temperatures. By using these materials to prepare the deformation portion 21, the hardness of the deformation portion 21 can change with temperature. Among them, the deformation portion 21 can be converted to the first state when heated and to the second state when not heated. The hardness of the deformation portion 21 in the first state is less than that in the second state, that is, the deformation portion 21 can become softer in the first state and harder in the second state. It should be noted that the deformation portion 21 can expand or contract relative to the sound outlet portion 11 in the first state, the deformation portion 21 can undergo appropriate deformation in the second state, or the deformation portion 21 can also keep its shape unchanged in the second state. The embodiments of the present application do not make specific limitations on this.
[0035] Optionally, the shape of the deformation part 21 is umbrella-shaped. This setting is conducive to the full contact and fitting of the deformation part 21 with the surface of the user's ear canal.
[0036] It can be understood that a slope is provided on the top of the deformation part 21, and this slope design meets ergonomics, making the user wear more comfortably.
[0037] Specifically, there is an accommodation space 3 between the deformation part 21 and the sound output part 11. A heating element 4 is arranged in the accommodation space 3. When the heating element 4 is powered on, the heating element 4 can heat the deformation part 21 to the first state, making the deformation part 21 become relatively soft, which can reduce the extrusion force of the deformation part 21 on the user's ear. In this way, the problem of ear pain caused by long-term wearing of the user can be solved. When the heating element 4 is powered off, the heating element 4 no longer heats the deformation part 21, and the deformation part 21 can return to the second state, making the deformation part 21 become harder, increasing the support strength of the deformation part 21, and making the fitting between the deformation part 21 and the user's ear closer. In this way, the problem of the ear cap 2 shaking and making abnormal noises or the earphone falling off the ear can be solved. At the same time, to avoid the earphone falling off the user's ear, it can also avoid the earphone dropping and getting lost, reducing the loss of the user.
[0038] Specifically, the ear canals of different users are different, and different users may be suitable for ear caps 2 of different sizes. In the embodiment of the present application, since there is an accommodation space 3 between the deformation part 21 and the sound output part 11, this accommodation space 3 can accommodate at least partial deformation of the deformation part 21, so that the size of the ear cap 2 can have a certain adjustment range, so as to adapt to the ear canals of different users, meet the fitting degree of the ear canals of different users, and make the earphone in the present application meet the wearing needs of different users.
[0039] Furthermore, when the user is still, the earphone is not easy to fall or shake. In this case, the heating element 4 can be controlled to be powered on through an adjustment program instruction to heat the deformation part 21 to the first state, which can reduce the extrusion of the user's ear canal and relieve the pain in the user's ear; when the user is walking, running or jumping, the earphone is easy to fall or shake. In this case, the heating element 4 can be controlled to be powered off through an adjustment program instruction to increase the supporting force of the deformation part 21 on the user's ear canal, and then ensure the tightness of the cooperation between the deformation part 21 and the user's ear canal, and avoid abnormal noises caused by the ear cap 2 shaking in the user's ear canal or the earphone falling off from the user's ear canal. That is, in the embodiment of the present application, when the user is not moving, the hardness of the deformation part 21 will become soft, which can relieve the pain in the user's ear and solve the problem of long-term wearing comfort; when the user is moving, the hardness of the deformation part 21 will become hard, which can solve the problems of abnormal noises of the ear cap 2 or the earphone falling off when the user is moving.
[0040] Specifically, the material of the heating element 4 can be copper, aluminum, or alloy materials, etc. Since copper has better heat dissipation ability, when choosing copper to prepare the heating element 4, after the heating element 4 is powered off, because the deformation part 21 is near the heating element 4, the deformation part 21 can also dissipate heat quickly, facilitating the rapid cooling of the deformation part 21 and its restoration to the second state. In some specific embodiments, the heating element 4 can be copper foil, aluminum foil, etc., which can not only meet the heating requirement of the heating element 4 for the deformation part 21 but also meet the requirement of fast heat dissipation of the heating element 4.
[0041] In some embodiments, the heating element 4 can be connected to the side of the deformation part 21 facing the accommodation space 3, so that the heating element 4 can directly heat the deformation part 21. In some other embodiments, the heating element 4 can also be connected to the side of the sound output part 11 facing the accommodation space 3, so that the heating element 4 can directly heat the sound output part 11, enabling the sound output part 11 to transfer heat to the deformation part 21. Moreover, after the deformation part 21 is squeezed, it can also approach or contact the heating element 4, so that the heating element 4 can also heat the deformation part 21 simultaneously.
[0042] In some alternative embodiments, the ear cap 2 further includes a first connecting part 22 connected to the deformation part 21. The first connecting part 22 is sleeved on the sound output part 11, and the deformation part 21 and the first connecting part 22 are coaxially arranged. One end of the first connecting part 22 away from the earphone main body 1 is connected to one end of the deformation part 21 away from the earphone main body 1, and the first connecting part 22 and the deformation part 21 enclose to form the accommodation space 3; the heating element 4 is arranged in the accommodation space 3.
[0043] In the embodiment of the present application, the first connecting part 22 covers the sound output part 11, so that the ear cap 2 can be connected to the sound output part 11 through the first connecting part 22, which can increase the contact area between the ear cap 2 and the sound output part 11 and facilitate ensuring the connection reliability between the ear cap 2 and the sound output part 11.
[0044] Further, the heating element 4 is connected to the side of the first connecting part 22 facing the deformation part 21.
[0045] In the embodiment of the present application, connecting the heating element 4 to the side of the first connecting part 22 facing the deformation part 21 enables the heating element 4 to be arranged close to the deformation part 21, facilitating the heating of the deformation part 21 by the heating element 4. Moreover, there is a gap between the heating element 4 and the deformation part 21, which also facilitates the rapid cooling of the deformation part 21 and its restoration to the second state when the heating element 4 is powered off.
[0046] Specifically, the inner circumference of the first connecting part 22 can be sleeved outside the sound output part 11 and connected to the sound output part 11, and the outer circumference of the first connecting part 22 and the deformation part 21 enclose to form the accommodation space 3.
[0047] In some embodiments, the first connecting portion 22 can be in interference fit with the sound output portion 11 to ensure the reliability of the connection between the first connecting portion 22 and the sound output portion 11. In other embodiments, the first connecting portion 22 can also be installed and fixed to the sound output portion 11 by adhesion, and the embodiments of the present application do not make specific limitations in this regard.
[0048] Furthermore, a first limiting member can be provided on the side of the first connecting portion 22 facing the sound output portion 11, and a second limiting member can be correspondingly provided on the side of the sound output portion 11 facing the first connecting portion 22. The second limiting member can be snap-fitted with the first limiting member. Among them, one of the first limiting member and the second limiting member can be a protrusion, and the other can be a groove, and the snap-fitting is realized through the cooperation of the protrusion and the groove.
[0049] Specifically, one end of the first connecting portion 22 away from the earphone main body 1 is connected to one end of the deformation portion 21 away from the earphone main body 1, and the first connecting portion 22 and the deformation portion 21 enclose a receiving space 3. In this way, along the direction close to the earphone main body 1, the gap between the deformation portion 21 and the first connecting portion 22 shows an increasing trend, and the diameter of the deformation portion 21 can show an increasing trend, so that the deformation portion 21 is convenient to be inserted into the user's ear.
[0050] In some embodiments, the first connecting portion 22 and the deformation portion 21 can be integrally formed to improve the structural stability of the ear cap 2. In other embodiments, the first connecting portion 22 and the deformation portion 21 can also be connected by a splicing and fixing method. Among them, the materials of the first connecting portion 22 and the deformation portion 21 can be the same or different, etc., and the embodiments of the present application do not make specific limitations in this regard.
[0051] For example, the first connecting portion 22 and the deformation portion 21 can be injection-molded at one time, or the first connecting portion 22 and the deformation portion 21 can also be prepared by a two-color injection molding process, or the first connecting portion 22 and the deformation portion 21 are fixedly bonded by glue.
[0052] Specifically, the first connecting portion 22 can play a role in installing and fixing the ear cap 2 to the sound output portion 11, and can also be designed to have a relatively high hardness to improve the connection strength of the first connecting portion 22.
[0053] Specifically, the heating element 4 is connected to the side of the first connecting portion 22 facing the deformation portion 21. Since the first connecting portion 22 is installed and fixed to the sound output portion 11, the first connecting portion 22 is not easily deformed, and thus the deformation of the heating element 4 can be avoided, which is beneficial to ensuring the structural stability and service life of the heating element 4.
[0054] Specifically, as shown in the figure, a heating element 4 is attached to the surface of the first connecting portion 22 facing the accommodating space 3. When the user remains stationary, the heating element 4 is powered on. Since the first connecting portion 22 is connected to the heating element 4, the first connecting portion 22 is heated. Since the first connecting portion 22 is connected to the deformation portion 21, the first connecting portion 22 can transfer heat to the deformation portion 21. After the deformation portion 21 is squeezed, it can approach the heating element 4, so that the heating element 4 can directly heat the deformation portion 21. Among them, the entire ear cap 2 is heated and softened.
[0055] When the user is walking, the heating element 4 is powered off and no longer heats the first connecting portion 22 and the deformation portion 21. The heating element 4 dissipates heat quickly, which can also drive the deformation portion 21 to dissipate heat quickly, so that the deformation portion 21 remains in a relatively hard state.
[0056] Optionally, the earphone main body 1 further includes a housing 12. The sound output portion 11 protrudes from the housing 12. A sound cavity is provided in the housing 12, and a vent hole communicating with the sound cavity is provided on the housing 12; at least two protrusions 221 are provided at the end of the first connecting portion 22 close to the housing 12. The protrusions 221 are in contact with the housing 12. The at least two protrusions 221 are arranged at intervals along the circumferential direction of the first connecting portion 22. A first sound output channel 222 is formed between two adjacent protrusions 221, and the first sound output channel 222 faces the vent hole.
[0057] In the embodiment of the present application, the first connecting portion 22 can be in contact with the housing 12 through the protrusions 221, which can decorate the connection between the ear cap 2 and the housing 12, thereby improving the aesthetics of the earphone. In addition, at least two protrusions 221 are provided at the end of the first connecting portion 22 close to the housing 12, so that a first sound output channel 222 is formed between two adjacent protrusions 221. The first sound output channel 222 can communicate with the sound cavity in the housing 12 through the vent hole on the housing 12, which can improve the sound output effect and sound quality of the earphone.
[0058] Specifically, the protrusion 221 can be in the shape of an arc-shaped long strip, a straight-shaped long strip, a block or a disc, etc. In the embodiment of the present application, the shape of the protrusion 221 is not specifically limited.
[0059] Specifically, the number of the protrusions 221 can be two, three or four, etc. In the embodiment of the present application, the number of the protrusions 221 is not specifically limited.
[0060] Specifically, a relief hole can be provided at the position of the housing 12 opposite to the protrusion 221. The conductive member 14 can pass through the relief hole and be electrically connected to the heating element 4 and the circuit board 13 in the earphone main body 1 respectively, so as to connect the heating element 4 to the circuit board 13 and realize power-on heating.
[0061] In some other alternative embodiments of the present application, the ear tip 2 further includes a second connecting portion, and the second connecting portion is respectively connected to the same end of the deformation portion 21 and the sound outlet portion 11. The deformation portion 21, the second connecting portion, and the sound outlet portion 11 together enclose a receiving space 3; the heating element 4 is connected to the side of the sound outlet portion 11 facing the deformation portion 21.
[0062] In the embodiment of the present application, the deformation portion 21, the second connecting portion, and the sound outlet portion 11 together enclose a receiving space 3, and the heating element 4 is connected to the side of the sound outlet portion 11 facing the deformation portion 21, which is convenient for arranging the heating element 4 near the deformation portion 21, that is, the heating element 4 can heat the deformation portion 21, and it can also prevent the heating element 4 from being deformed and broken as the deformation portion 21 deforms. Moreover, there is a gap between the heating element 4 and the deformation portion 21, which is also convenient for the deformation portion 21 to quickly cool down and return to the second state when the heating element 4 is powered off.
[0063] Specifically, the second connecting portion can be integrally formed with the deformation portion 21 to ensure the structural strength of the ear tip 2. The second connecting portion and the sound outlet portion 11 can be fixed by means of snap connection, snap fit connection or bonding, etc., and the embodiments of the present application do not make specific limitations in this regard.
[0064] Specifically, the heating element 4 is attached to the surface of the sound outlet portion 11 facing the receiving space 3. When the user remains stationary, the heating element 4 is powered on. Since the second heating portion is connected to the heating element 4, the heating element 4 can directly heat the second connecting portion. Since the second heating portion is connected to the deformation portion 21, the second heating portion can transfer heat to the deformation portion 21. After the deformation portion 21 is squeezed, it can approach the heating element 4, so that the heating element 4 can directly heat the deformation portion 21.
[0065] In some alternative embodiments, the heating element 4 can be arranged around the sound outlet portion 11, which can increase the heat radiation area of the heating element 4, so that the heating element 4 can perform heat radiation on the entire surface of the deformation portion 21, which is convenient for improving the reliability and convenience of heating the deformation portion 21, and moreover, it can improve the uniformity of heating the deformation portion 21 by the heating element 4.
[0066] In some embodiments, the heating element 4 can be wrapped around the side of the first connecting portion 22 facing the deformation portion 21, which can increase the contact area between the heating element 4 and the first connecting portion 22 and improve the reliability of fixing the heating element 4. In some other embodiments, the heating element 4 can be wrapped around the side of the sound outlet portion 11 facing the deformation portion 21, which can increase the contact area between the heating element 4 and the sound outlet portion 11 and improve the reliability of fixing the heating element 4.
[0067] Optionally, the heating element 4 at least includes a tapered section 41 and a circular ring section 42 connected in sequence, and a plurality of spaced notches 411 are formed in the circumferential direction of the tapered section 41.
[0068] In an embodiment of the present application, a plurality of spaced notches 411 are formed in the circumferential direction of the tapered section 41, which can improve the flatness of the tapered section 41, avoid wrinkles in the heating element 4, and further avoid the transfer of ear squeezing force through the deformation part 21 due to the wrinkles, thus preventing the user from feeling a foreign body sensation. Moreover, the heating element 4 can be connected to the circuit board 13 through the circular ring section 42, which can also improve the convenience of electrically connecting the heating element 4.
[0069] Specifically, in the embodiment of the present application, the number of the tapered sections 41, the number of the circular ring sections 42, the number of the notches 411 on the tapered section 41, the width of the notches 411, etc. are not specifically limited.
[0070] In some other alternative embodiments, the heating element 4 includes a plurality of heating sheets, and the plurality of heating sheets are arranged at intervals in the circumferential direction of the sound outlet part 11.
[0071] In the implementation of the present application, the heating element 4 can be composed of a plurality of independent heating sheets, and each heating sheet is arranged separately, so that the area of each heating sheet is small, which is convenient for ensuring the flatness of the heating sheet and avoiding wrinkles in the heating sheet, thus preventing the user's ear from feeling a foreign body sensation. Moreover, the plurality of heating sheets are arranged at intervals in the circumferential direction of the sound outlet part 11, which can improve the heating balance of the heating element 4 on the deformation part 21.
[0072] Specifically, the number of the heating sheets is not specifically limited in the embodiment of the present application
[0073] In some alternative embodiments of the present application, the earphone main body 1 further includes a housing 12, a circuit board 13 and a conductive member 14. The sound outlet part 11 protrudes from the housing 12, and a second sound outlet channel 111 is arranged on the sound outlet part 11; the circuit board 13 is arranged in the housing 12, and a sound outlet hole 131 is formed at a position of the circuit board 13 opposite to the second sound outlet channel 111; the heating element 4 is connected to the circuit board 13 through the conductive member 14.
[0074] In the embodiment of the present application, the heating element 4 is connected to the circuit board 13 through the conductive member 14, which is convenient for energizing the heating element 4. A sound outlet hole 131 is formed at a position of the circuit board 13 opposite to the second sound outlet channel 111, which can ensure the transmission of sound and thus ensure the sound output effect of the earphone.
[0075] Specifically, the circuit board 13 can be electrically connected to a battery in the earphone main body 1 through a wire harness to transmit an electrical signal to the heating element 4. Among them, the circuit board 13 can be a printed circuit board 13 (Printed Circuit Board, PCB), or it can also be a flexible printed circuit (Flexible Printed Circuit Board, FPC). In the embodiment of the present application, this is not specifically limited.
[0076] Specifically, a avoidance hole may be opened on the housing 12 , and the conductive member 14 may be passed through the avoidance hole, so that the conductive member 14 can connect the heating element 4 to the circuit board 13 .
[0077] Specifically, the conductive member 14 may be a conductive column such as a copper column, an iron column, or a cable, etc. The specific form of the conductive member 14 is not limited in the embodiment of the present application.
[0078] Specifically, the sound outlet portion 11 protrudes from the housing 12, so that the ear cap 2 can be installed through the sound outlet portion 11 and the ear cap 2 can be inserted into the user's ear. The inner wall of the sound outlet portion 11 can enclose a second sound outlet channel 111, and the outer wall of the sound outlet portion 11 can be assembled with the ear cap 2.
[0079] In some other embodiments of the present application, the earphone body 1 also includes a sensor, a control element and a power supply element. The control element is electrically connected to the sensor and the power supply element, respectively, and the power supply element is electrically connected to the heating element 4. When the sensor detects that the earphone remains stationary, the control element controls the power supply element to supply power to the heating element 4. When the sensor detects that the earphone remains dynamic, the control element controls the power supply element to stop supplying power to the heating element 4.
[0080] In the embodiment of the present application, the state of the earphone is detected by a sensor, so as to timely discover the state of the user, and then timely switch the heating element 4 on or off according to the state of the user, thereby improving the compatibility of the earphone with the user and enhancing the user's usage experience.
[0081] Specifically, when the sensor detects that the earphone remains stationary, it determines that the user is not moving. After transmitting the signal to the control element, the control element controls the power supply element to supply power to the heating element 4, so that the heating element 4 heats the deformation part 21 to the first state, reducing the squeezing force of the ear cap 2 on the user's ear canal, thereby reducing the risk of the user's ear swelling and pain. When the sensor detects that the earphone remains dynamic, it determines that the user is walking, running, jumping or exercising. After transmitting the signal to the control element, the control element controls the power supply element to cut off the power, and the deformation part 21 can cool down and return to the second state and keep the shape unchanged, thereby enhancing the matching density between the ear cap 2 and the user's ear canal, thereby reducing the problem of the earphone falling off or shaking to produce abnormal noise.
[0082] Specifically, the sensor may be an infrared (IR) photosensitive sensor, an optical sensor, a Hall sensor, an acceleration sensor, a capacitive sensor, or a microphone sensor, etc., which is not specifically limited in the embodiments of the present application. The control element may be a control circuit or a control chip on a main circuit board 13 in the earphone body 1. The power supply element may be a power supply in the earphone body 1.
[0083] The earphones described in the embodiments of the present application have at least the following advantages:
[0084] In an embodiment of the present application, the ear tip of the earphone has a deformable portion that is used to contact the user's ear canal, and the hardness of the deformable portion in the first state is greater than its hardness in the second state. In this way, when the user is stationary, the heating element can be controlled to be energized to heat the deformable portion of the ear tip to the first state, so that the deformable portion becomes softer, which can reduce the degree of squeezing on the user's ears, thereby solving the problem that the user's ears feel swollen and painful after wearing the earphone for a long time.
[0085] An earphone device is also disclosed in an embodiment of the present application. The earphone device includes an earphone case and the earphone described in any one of the above embodiments; the earphone is detachably arranged in the earphone case.
[0086] In an embodiment of the present application, when the earphone is placed in the earphone case, the earphone can be stored and charged; when the earphone is taken out of the earphone case, it is convenient for the user to insert the earphone into the ear canal for wearing.
[0087] The earphone device described in the embodiment of the present application can achieve the same beneficial effects as the above earphone, which will not be elaborated here.
