This application claims priority to the Chinese patent application filed with the China Patent Office on June 30, 2023, with application number 202321699459.6 and application name “A kind of earphones”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of consumer electronic products, and in particular to a headset. Background Art

[0003] With the development of society, the application scope of headphones is becoming wider and wider, and they are widely used in office environments and anywhere for listening to music or entertainment.

[0004] Currently, the production process for headphones typically involves first injection-molding an inner bracket with a glue dispensing groove, then injecting a silicone layer onto the outer surface of the inner bracket. Finally, glue is applied into the glue dispensing groove to bond the headphone cover to the inner bracket. However, the top surface of the current glue dispensing groove is typically flush with the top surface of the silicone layer. This results in silicone oil easily flowing into the glue dispensing groove during the silicone layer injection process, affecting the adhesion between the glue in the glue dispensing groove and the headphone cover.

[0005] Current earphones all have charging contacts set on them, and the earphones are placed in an earphone box and charged through the earphone box. In order to ensure the appearance of the earphones, the prior art usually sets the charging contacts on the side of the ear hook of the earphone that touches the skin, and increases the shortest distance between the two charging electrodes to prevent short circuits between the charging electrodes caused by sweat, water droplets, dust, etc. For example, paragraph 137 of the utility model patent for a kind of earphones with publication number CN217159949 U states: The two charging electrodes can be set to be invisible when worn, for example, both facing the user's skin, so as to take into account the appearance quality of the earphones. However, since both charging electrodes are facing the user's skin, when the user sweats, it is easy for the earphones to short-circuit due to the effect of sweat.

[0006] Current headphones typically place function buttons such as the power button and volume button on the front of the sound-producing part, opposite the user's ears. This makes it easy to accidentally touch these buttons. For example, when a user is lying down to rest, they may press the buttons and cause accidental touches, affecting the user experience. To overcome this problem, a Bluetooth headset with publication number CN216795245U, titled "Anti-accidental Touch," uses a protective cover to cover the buttons to prevent accidental touches during use. However, this solution is complex in structure and significantly affects the overall appearance of the headset.

[0007] In summary, existing earphones have problems of poor assembly stability and poor performance.

[0008] Summary of the Invention

[0072] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0073] The following first explains the wearing state involved in the article, the front, back, upper and lower sides of the ear, the human body's sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, horizontal axis, and the definitions of the X, Y, and Z directions.

[0074] The definition of wearing state is as follows: Based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, a simulator containing a head and its (left and right) ears can be made (please refer to Figure 1), such as GRASKB0065. Therefore, descriptions such as "the user wears headphones" or "the headphones are in a wearing state" in this application may refer to the headphones being worn on the ears of the aforementioned simulator. Based on this, the "wearing state" described in this application may refer to the normal wearing state after the headphones are worn on the ears of the aforementioned simulator; for the sake of convenience of description, the aforementioned normal wearing state can be further illustrated from the front side, back side, and other perspectives of the ear. Of course, due to individual differences among users, the actual wearing state of the headphones may be different from the aforementioned normal wearing state.

[0075] The front, back, upper and lower sides of the ear are defined as follows: the "front side of the ear" mentioned in this application is a concept relative to the "back side of the ear", the former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head. The upper side of the ear in this application refers to the side close to the upper edge of the ear, and the upper edge refers to the part of the helix of the ear close to the triangular fossa of the ear; the lower side of the ear refers to the side close to the lower edge of the ear, and the lower edge refers to the part of the helix of the ear close to the earlobe. They are all for the user's ear.

[0076] The sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, and horizontal axis of the human body are defined as follows: As is well known in fields such as medicine and anatomy, the three basic planes of the human body are the sagittal plane, coronal plane, and horizontal plane, as well as the three basic axes of the human body are the sagittal axis, coronal axis, and vertical axis. The sagittal plane is a plane perpendicular to the ground, taken along the anterior-posterior direction of the body, dividing the human body into left and right parts; the coronal plane is a plane perpendicular to the ground, taken along the lateral direction of the body, dividing the human body into anterior-posterior parts; and the horizontal plane is a plane parallel to the ground, taken along the lateral direction of the body, dividing the human body into upper and lower parts. Accordingly, the sagittal axis is the axis perpendicular to the coronal plane, passing through the anterior-posterior direction; the coronal axis is the axis perpendicular to the sagittal plane, passing through the lateral direction of the body; and the vertical axis is the axis perpendicular to the horizontal plane, passing through the lateral direction of the body.

[0077] The definitions of the X, Y, and Z directions are as follows: As shown in Figure 2, for the convenience of description, the X, Y, and Z directions are defined separately, the X direction is defined as being parallel to the sagittal axis and pointing to the front of the human body, the Y direction is defined as being parallel to the coronal axis and pointing to the right side of the human body (outward along the paper surface of Figure 2), and the Z direction is defined as being parallel to the vertical axis and pointing upward to the human body.

[0078] The above direction definitions are only for ease of description. In accordance with the principles of this technical solution, the X, Y, and Z directions can be defined arbitrarily, including but not limited to axial symmetry, angular symmetry, and other definitions of the above directions.

[0079] As shown in FIG3 , the first embodiment of the earphone of the present application includes an ear hook and a main body 2 , and the main body 2 is arranged at one end of the ear hook.

[0080] When worn, the main body 2 is arranged in cooperation with the front side of the ear. The main body 2 has a side surface extending from the front side close to the ear to the front side away from the ear, and the control device 30 is arranged on the side surface.

[0081] This embodiment takes into account that current headphones usually set the control device 30 on the side of the main body 2 opposite to the user's ear, which is easy to be accidentally touched. Therefore, this embodiment mainly changes the setting position of the control device 30 and sets the control device 30 on the side surface of the main body 2 extending from the front side close to the ear to the front side away from the ear. Not only is it not easy to come into contact with other parts of the body, but it also does not affect the user's activities or rest, and will not be accidentally touched when the user is active or resting, thereby improving the user experience.

[0082] As an implementation scheme, in this embodiment, the control device 30 is provided on the first side circumferential surface 5 of the side circumferential surface facing the upper edge of the ear portion.

[0083] Please refer to Figures 2-4 again. In this embodiment, the main body 2 can be set to an approximately tetrahedral structure. The first side circumferential surface 5 refers to the side of the upper edge of the main body 2 facing the ear, the second side circumferential surface 6 of the main body 2 refers to the side of the main body close to the user's ear, that is, the side where the sound hole is provided, and the third side circumferential surface 7 refers to the side opposite to the second side circumferential surface 6 and adjacent to the first side circumferential surface 5.

[0084] Conventional headphones typically place the control device 30 on the side of the main body 2 opposite the user's ear, that is, on the third side surface 7. In this embodiment, the control device 30 is placed on a first side surface adjacent to the second and third side surfaces 6 and 7, extending from the front side closest to the ear toward the front side away from the ear, further preventing accidental touches.

[0085] Furthermore, in this embodiment, when worn, the angle α between the first side surface 5 and the horizontal plane of the human body is 30°-45°. Setting the angle between the first side surface 5 and the horizontal plane to 30°-45° is more ergonomic. Positioning the control device 30 on the first side surface 5 at an angle of 30°-45° with the horizontal plane of the human body makes it easier to operate the control device, improving the user experience.

[0086] In other embodiments, the angle between the first side surface 5 and the horizontal plane of the human body can also be set according to the shape of the ear, for example, preferably 32°-43°, and further preferably 30°-40°. This application does not limit this angle.

[0087] In order to further enhance the user experience and facilitate the user to operate the control device 30 , in this embodiment, the panel of the control device 30 is raised from the first side surface 5 .

[0088] Referring to FIG. 4 , in this embodiment, a power button 4 is provided on the surface of the ear hook facing the back of the head or ear. The power button 4 is a physical button, which can further prevent accidental touches.

[0089] Please refer to Figures 5 and 6 , based on the first embodiment shown in Figures 3 and 4 , and the following implementation can also serve as a second embodiment of the earphone of the present application.

[0090] In this embodiment, the control device 30 includes a main control chip and a sensor module. The sensor module includes a pressure sensor for receiving press gestures and a capacitive touch sensor for receiving touch gestures, including conventional touch gestures such as tap-and-hold and swipe. The main control chip is electrically connected to the pressure sensor and the capacitive touch sensor, respectively.

[0091] This embodiment sets up two different types of sensors to receive the two types of gestures, pressing and touching, through different sensors, namely a pressure sensor and a capacitive touch sensor. This can separate the pressure signal generated by the pressing operation and the touch signal generated by the touch, thereby preventing misoperation and further preventing accidental touches.

[0092] Furthermore, the capacitive touch sensor is designed to receive swipe gestures. Because the capacitive touch sensor is designed to receive only swipe gestures, it blocks point-to-point touch gestures similar to press gestures. Press gestures require applying a certain amount of pressure to the pressure sensor, further separating the two gestures and preventing accidental touches.

[0093] The working principles of the pressure sensor and the capacitive touch sensor in this embodiment are described below.

[0094] In this embodiment, in order to prevent false triggering of the pressing operation when picking up the earphones, a trigger threshold is set for the pressure sensor based on actual experience values. The relevant operation of the earphones is triggered only when the pressing pressure is greater than or equal to the trigger threshold. As a preferred implementation, this embodiment sets the trigger threshold to 120g.

[0095] When the pressing pressure is less than 120g, sliding is triggered; when the pressing pressure is greater than or equal to 120g, sliding is blocked and only pressing is triggered. The pressure sensor detects deformation, generating a voltage change, and the main control chip then determines whether a press is made based on the voltage change. In other embodiments, the trigger threshold can also be set based on actual experience.

[0096] The capacitive touch sensor in this embodiment has a self-calibration function. Due to environmental changes, the capacitance remains at a certain value for 10 seconds, and then self-calibration is considered necessary. The maintained sampled value is used as the new reference value (i.e., the actual surface value), replacing the original reference value.

[0097] Due to environmental changes, when the baseline value is greater than the sampling value, calibration is performed immediately, and the existing sampling value is used as the baseline value.

[0098] As shown in FIG6 , in this embodiment, the control device 30 includes a panel for contacting a user's limbs, a capacitive touch sensor, and a pressure sensor stacked in sequence from the outside to the inside.

[0099] In order to better realize the judgment of sliding gestures, at least three capacitive touch sensors are sequentially arranged along the extension direction of the panel. In this embodiment, three are preferably provided.

[0100] As shown in FIG5 and FIG6 , the pins Touch1 , Touch2 , and Touch3 of the main control chip are electrically connected to the three capacitive touch sensors, respectively, and the pin Touch_SH of the main control chip is electrically connected to the pressure sensor.

[0101] This embodiment is provided with three positioning points, namely three soldering pads, for soldering the three capacitive touch sensors. The three capacitive touch sensors are respectively three touch pieces and are continuously arranged together.

[0102] When determining whether it is a sliding gesture, the duration of sliding across two adjacent touch panels can be used to determine. If the duration is within a threshold range, it is considered a sliding gesture. The threshold can be set based on actual experience. For example, in this embodiment, it is preferably greater than 50ms and less than 1s.

[0103] Specifically, when the touch sheet of the first capacitive touch sensor is slid, the change in capacitance is transmitted to the main control chip, and timestamp t1 is obtained. When the touch sheet of the second capacitive touch sensor is pressed, the change in capacitance is transmitted to the main control chip, and timestamp t2 is obtained. If the difference between t2 and t1 is greater than 50ms and less than 1s, it can be considered as a sliding gesture.

[0104] In this embodiment, a reinforcing metal sheet is stacked between the pressure sensor and the capacitive touch sensor. The reinforcing metal sheet may preferably be a steel sheet.

[0105] The reinforcing metal sheet can enhance the strength of the entire control device and improve its service life.

[0106] In this embodiment, the side of the reinforcing metal sheet facing the pressure sensor has a groove. This groove aligns with the extension direction of the panel, thereby reducing the contact area with the pressure sensor and concentrating the pressure in the middle portion, thereby better transmitting the pressure to the pressure sensor. Preferably, two grooves are provided in parallel at intervals in this embodiment.

[0107] The present application proposes an earphone. Please refer to Figures 7 to 9. The first embodiment of the earphone of the present application includes a main body 2, a connecting part 1 and a battery part 3. The connecting part 1 connects the main body 2 and the battery part 3. The battery part 3 includes a battery shell, a battery (not shown in the figure) and a charging structure 40. The battery is arranged in the battery shell, and the charging structure 40 is arranged on the battery shell.

[0108] When the earphones are worn, the first surface of the battery housing contacts the back of the ear, while the second surface contacts the scalp near the back of the ear. The charging structure 40 is located on a surface of the battery housing that does not contact the skin. This avoids sweat from wetting the charging structure 40 and causing a short circuit. It also prevents dirt from the user's skin from contaminating the charging structure 40, potentially preventing charging failure or poor contact during charging. This improves the lifespan of the earphones.

[0109] Referring to Figures 10 to 12 , the charging structure 40 includes a first charging connector 50 and a second charging connector 60 spaced apart from each other. One of the first and second charging connectors 50 and 60 is a positive charging connector, and the other is a negative charging connector. The specific order in which the first and second charging connectors 50 and 60 are installed is not limited in this embodiment.

[0110] As an embodiment, referring to Figures 10 to 12 , to facilitate disassembly and maintenance of the charging structure 40, this embodiment detachably mounts the charging structure 40 on the battery housing. Specifically, a snap-fit ​​slot is provided on the battery housing, and a corresponding snap-fit ​​structure 70 is provided on the charging structure 40. The charging structure 40 snaps into the snap-fit ​​slot via the snap-fit ​​structure 70.

[0111] As another embodiment, in order to improve the assembly stability of the charging structure 40 , the charging structure 40 and the battery housing may be integrally formed.

[0112] Based on the first embodiment shown in FIG. 7 to FIG. 9 , a second embodiment of the earphone of the present application is proposed.

[0113] In this embodiment, the battery housing includes a third surface, a fourth surface, and a fifth surface. The third surface is the surface of the battery housing opposite the first surface, the fourth surface is opposite the second surface, and the fifth surface is the lower surface of the battery housing. The charging structure 40 is disposed on at least one of the third, fourth, and fifth surfaces. None of the third, fourth, and fifth surfaces come into contact with the user's skin. Placing the charging structure 40 on at least one of the third, fourth, and fifth surfaces that does not come into contact with the user's skin not only prevents the charging structure 40 from being wetted by the user's sweat and causing a short circuit, but also prevents dirt on the user's skin from contaminating the charging structure 40, which could result in charging failure or poor contact during charging. This, in turn, increases the lifespan of the earphones and prevents the charging structure 40 from causing a sense of pressure on the user, thereby improving the user experience.

[0114] Please refer to FIG11 , which provides a third embodiment of the earphone of the present application based on the first embodiment shown in FIG7 to FIG9 .

[0115] In this embodiment, a magnetic attraction structure is provided in the battery housing, and the magnetic attraction structure is close to the charging structure 40 .

[0116] The magnetic attraction structure includes at least one magnetic block 80 . The magnetic block 80 is disposed between the first charging connector 50 and the second charging connector 60 . The distance between the first charging connector 50 and the second charging connector 60 is greater than the length of the magnetic block 80 .

[0117] During charging, the magnetic structure and the magnet inside the earphone charging box are attracted to each other, so that the charging contacts 90 of the first charging connector 50 and the second charging connector 60 firmly correspond to the charging head inside the charging box, making charging convenient.

[0118] In this embodiment, a metal coating is provided on the charging contacts 90 of the first charging connector 50 and the second charging connector 60 .

[0119] The metal coating has a conductive function. During charging, the metal coating on the first charging connector 50 and the second charging connector 60 contacts the charging head in the charging box to charge the earphones.

[0120] In this embodiment, the battery unit 3 can be configured as a tetrahedron, a cylindrical structure, an elliptical cross-section, or any other shape. The charging structure 40 is disposed at the rear end of the tetrahedron, cylindrical, or elliptical cross-section battery unit 3, and is positioned away from the user's ear skin. When the user wears the earphones, the charging structure 40 is not visible from the front or side of the user, thereby preventing sweat from contacting the charging structure 40 and causing a short circuit while also improving the aesthetics.

[0121] Please refer to FIG13 , which provides a fourth embodiment of the earphone of the present application based on the first embodiment shown in FIG7 to FIG9 .

[0122] In this embodiment, the connecting portion 1 is an ear hook, which includes an ear hook body, and a metal support 100 is provided in the ear hook body.

[0123] The earhook is an arc-shaped device that fits snugly against the user's ear. The connection between one end of the earhook and the main body 2 forms the headphone support point. The earhook is subject to increasing gravity from this support point toward the battery unit 3. This support point is the primary point of force applied when the user wears the headphones. Gravity gradually increases from this point toward the battery unit 3, allowing the entire headphone to rest on the user's ear using gravity. This ensures a perfect fit, preventing it from falling, and enhances wearing comfort and user experience.

[0124] This embodiment uses a metal support 100, which not only enhances the strength of the ear hook and prevents it from bending under the action of gravity, but also makes it easier for users to adjust the position of the earphone support point according to actual needs to improve its wearing comfort.

[0125] The metal support 100 may be made of nickel-titanium alloy or titanium wire, which is not limited in this embodiment.

[0126] A flexible circuit board is also provided in the ear hook, and the flexible circuit board is close to 10.

[0127] The flexible circuit board can be configured to cover a portion of 10 or to wrap the entire 10 . This embodiment does not limit the specific matching structure between the flexible circuit board and 10 .

[0128] The present application arranges the charging structure on the surface of the battery shell that does not contact the skin. When worn, since the charging structure does not contact the user's skin, it can prevent the user's sweat from wetting the charging structure and causing a short circuit. It can also prevent dirt on the user's skin from contaminating the charging structure and causing charging failure, or poor contact during charging, thereby improving the service life of the earphones.

[0129] The present application proposes an earphone, please refer to Figures 14 to 17. The first embodiment of the earphone of the present application includes a connecting part 1, a main body 2 and a battery part 3.

In this embodiment, the battery part 3 includes a second lower shell 301, a second upper cover 302 bonded to the second lower shell 301, and a second speaker front shell 308 is provided at the bottom of the second lower shell 301. The second lower shell 301 includes a second inner bracket 303 and a second silicone outer layer 304 wrapped around the outer periphery of the second inner bracket 303. A second glue dispensing groove 305 is provided on the top of the second inner bracket 303, and a second glue sealing bone position 306 is provided on the outer wall of the second glue dispensing groove 305. The second glue sealing bone position 306 is molded by silicone sealing, and the top surface of the second glue sealing bone position 306 is higher than the top surface of the second silicone outer layer 304.

[0137] The top surface of the second sealing frame 306 is higher than the top surface of the second silicone outer layer 304. When injecting the second silicone outer layer 304, the second sealing frame 306 can prevent silicone oil from flowing into the second glue dispensing groove 305 of the second inner bracket 303, thereby preventing the silicone oil from affecting the bonding effect between the glue in the glue dispensing groove and the earphone cover, thereby improving the assembly stability of the earphone cover and the second inner bracket 303.

[0138] The outer wall of the second sealing frame 306 is provided with a step structure, and the top of the second silicone outer layer 304 is provided with a second ridge 307 extending toward the step structure. The second ridge 307 is located on the step structure, and the top surface of the second ridge 307 is lower than the top surface of the second sealing frame 306.

[0139] In this embodiment, the step structure is provided on the outer wall of the second sealing frame 306, and the second ridge 307 is located on the step structure, which can make the assembly of the second silicone outer layer 304 and the second inner bracket 303 more stable and reliable, and the top surface of the second ridge 307 is lower than the top surface of the second sealing frame 306, which can further prevent silicone oil from flowing into the glue dispensing groove and affecting the bonding effect between the glue and the upper cover of the earphone.

[0140] The end of the second upper cover 302 is provided with a slot corresponding to the second glue-sealing rib 306. The outer wall of the slot abuts the second ridge 307, while the inner wall of the slot extends into the second glue-dispensing groove 305 and abuts the bottom of the second glue-dispensing groove 305. This not only strengthens the bond between the second upper cover 302, the second silicone outer layer 304, and the second inner bracket 303, and prevents silicone oil from flowing into the glue-dispensing groove and affecting the adhesion between the glue and the upper cover of the earphone, but also provides a waterproof effect, preventing water outside the battery unit 3 from entering the second inner bracket 303, thereby extending the service life of the earphones.

[0141] As an implementation plan, in this embodiment, the width of the second sealing frame 306 is less than or equal to 1.8 mm, thereby increasing the internal space volume of the battery part 3 to facilitate the assembly of the battery. Of course, in other embodiments, the width of the second sealing frame 306 can also be set according to actual needs, and this embodiment does not limit this.

[0142] The beneficial effect of the earphones of the present application is: through the above technical solution, the top surface of the first sealing bone is higher than the top surface of the first silicone outer layer.
