However, the wireless headset is usually small and exquisite, the internal space is very limited, and meanwhile, the indispensable devices of the wireless headset such as a battery, a speaker, a main board and an antenna are also required to be accommodated, and the introduction of the touch sensor will reduce the space of other devices, thereby causing interference between the structure and the function, and particularly having a great influence on the antenna. In some designs, to make room for the touch sensor by shortening the antenna size, interference between the two is avoided. However, this has an effect on the antenna performance, resulting in a decrease in the transmission performance of the wireless headset.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2 together, fig. 1 is a plan view illustrating an internal structure of a wireless headset 100 according to an embodiment of the present disclosure, and fig. 2 is a side view illustrating the internal structure of the wireless headset 100 according to an embodiment of the present disclosure. As shown in fig. 1 and 2, the wireless headset 100 includes a touch sensing unit 1 and an antenna body 2, wherein the antenna body 2 surrounds the touch sensing unit 1 and is spaced apart from the touch sensing unit 1, and the antenna body 2 forms a ring structure having an opening. That is, the loop structure formed by the antenna body 2 is an unclosed loop structure.
Thus, in the present application, the antenna body 2 is disposed around the touch sensing unit 1 and forms a ring structure having an opening, so that the size/length required for the antenna body 2 can be ensured to ensure the antenna performance, and the overall size of the wireless headset 100 can be reduced, and the interference between the antenna body 2 and the touch sensing unit 1 can be avoided by disposing the antenna body 2 at an interval from the touch sensing unit 1. Therefore, the touch sensing function can be integrated and the performance of the antenna body 100 can be ensured not to be affected while the volume of the wireless headset 100 is not increased.
As shown in fig. 1, the touch sensing unit 1 includes at least two touch sensing sheets 11, and the at least two touch sensing sheets 11 are arranged at intervals along a preset direction, that is, the at least two touch sensing sheets 11 are arranged along the same direction and are spaced from each other. The antenna body 2 comprises a first antenna segment 21, a second antenna segment 22 and a third antenna segment 23, wherein the first antenna segment 21 is located on one side of the two touch sensing pieces 11, the third antenna segment 23 is located on the other side of the at least two touch sensing pieces 11, and the second antenna segment 22 connects the first antenna segment 21 and the third antenna segment 23. Specifically, the antenna body 2 extends along a first direction at one side of the two touch sensing pieces 11 to form the first antenna segment 21, and extends a preset length along a second direction to form the third antenna segment 23 after extending all the touch sensing pieces 11 and then bending to extend to the other side of the at least two touch sensing pieces 11 to form the second antenna segment 22, the second direction is parallel to the first direction and the arrangement direction of the at least two touch sensing pieces 11, that is, the preset direction, and the second direction is opposite to the first direction.
In this application, the term "space" means a space between two elements, for example, the antenna body 2 surrounds the touch sensing unit 1 and is spaced from the touch sensing unit 1, which means that: the antenna body 2 surrounds the touch sensing unit 1 and has a distance with the touch sensing unit 1, and the two do not contact or have an overlapping interval.
That is, the touch sensing unit 1 includes at least two touch sensing pieces 11 arranged at intervals, the antenna body 2 includes a first antenna segment 21, a second antenna segment 22 and a third antenna segment 23, and the first antenna segment 21 extends along the arrangement direction of the at least two touch sensing pieces 11 and extends through all the touch sensing pieces 11. Then, a second antenna segment 22 is formed by further bending and extending from the end of the first antenna segment 21 passing through all the touch sensing sheets 11. After the second antenna segment 22 extends to the other side of the at least two touch sensing sheets 11, a third antenna segment 23 is formed by extending a preset length from the end of the second antenna segment 22 extending to the other side toward the second direction.
Thus, the antenna body 2 forms a ring structure having an opening around the touch sensing unit 1.
Wherein the length of the third antenna segment 23 is smaller than the length of the first antenna segment 21. Specifically, as shown in fig. 1, the three-antenna segment 23 extends only through one touch sensing unit 1. Therefore, the third antenna segment 23 is not disposed at least partially on the other side of the at least two touch-sensitive sheets 11, and an opening of the antenna body 2 is formed.
Wherein, the wireless earphone 100 of this application can support bluetooth wireless communication, through second antenna segment 22 and third antenna segment 23 extends preset length, can guarantee that whole antenna body 2 can normally work at bluetooth 2.4GHz frequency channel, just preset length that three antenna segment 23 extends is showing and is being less than first antenna segment 21's length to, can not lead to controlling the back current radiation field on the both sides conductor and offset each other, reduce the antenna performance. Therefore, the preset length of the third antenna segment 23 can be designed in advance according to the requirement of satisfying the wireless communication requirement without causing the antenna performance to be reduced.
In some embodiments, as shown in fig. 1, the first and third antenna segments 21, 23 are straight segments and the second antenna segment 22 is an arc segment.
Obviously, in other embodiments, the first antenna segment 21 and the third antenna segment 23 may also be curved segments with some radians, or may be wave-shaped to increase the length of the antenna body 2, and the second antenna segment 22 may also be a broken segment, and so on.
As shown in fig. 1, the wireless headset 100 further includes a headset handle 3 and an earphone 4 disposed at one end of the headset handle 3, the at least two touch sensor pads 11 and the antenna body 2 are disposed in the headset handle 3, an arrangement direction (i.e., the preset direction) of the at least two touch sensor pads 11, the first direction and the second direction are parallel to a length direction of the headset handle 3, the first direction is a direction from being far away from the earphone 4 to being close to the earphone 4, and the second direction is a direction from being close to the earphone 4 to being far away from the earphone 4.
That is, as shown in fig. 1, the at least two touch-sensitive sheets 11 are sequentially arranged at intervals along the length direction of the earphone handle 3, the first antenna segment 21 may extend from a position of the touch-sensitive sheet 11 farthest from the earphone 4 toward the earphone 4, then, after passing through the touch-sensitive sheet 11 closest to the earphone 4, the second antenna segment 22 may be formed by bending and extending toward the other side of the at least two touch-sensitive sheets 11, and then, the third antenna segment 23 may be formed by extending in a direction away from the earphone 4.
The whole fixed end of the earphone handle 3 and the earphone 4 is also designed to be arc-shaped, and the bending radian of the second antenna segment 22 can be the same as that of the fixed end of the earphone handle 3 and the earphone 4.
As shown in fig. 1 and 2, an antenna feed point F1 is disposed in an area of the third antenna segment 23 corresponding to the touch-sensitive strip 11 closest to the earpiece 4. The touch-sensitive sheet 11 closest to the earpiece 4 is also the touch-sensitive sheet 11 located at the end closest to the third antenna segment 23. That is, the antenna feed point F1 is provided in the area of the touch-sensitive strip 11 at the corresponding end of the third antenna segment 23.
Further, in the present application, the antenna feeding point F1 of the antenna body 2 for connecting to a feed source is located at a certain position in the third antenna segment 23, and specifically located at a certain position in the third antenna segment 23 corresponding to the area closest to the touch-sensitive strip 11 of the earpiece 4.
As shown in fig. 1 and 2, the wireless headset 100 further includes a carrier plate 5, the headset 3 includes a headset housing 31, the at least two touch sensor pads 11 and the antenna body 2 are disposed on the carrier plate 5, the at least two touch sensor pads 11, the antenna body 2 and the carrier plate 5 are all accommodated in an accommodating space formed by the headset housing 31, and the carrier plate 5 is close to an inner surface of the headset housing 31.
That is, in the present application, the at least two touch-sensing pieces 11 and the antenna body 2 are both disposed on the supporting board 5, and the supporting board 5 is close to the inner surface of the earphone handle housing 31, so that the user can conveniently touch the at least two touch-sensing pieces 11 from the outer surface of the earphone handle housing 31. That is, the loading plate 5 is close to the inner surface of the housing on one side of the earphone handle housing 31, so that when a user touches the outer surface of the corresponding side of the earphone handle housing 31 with a finger, the distance between the finger and the loading plate 5 is relatively small, and the touch sensitivity can be improved.
In some embodiments, the earphone handle housing 31 is made of an insulating material, such as plastic, etc. The touch sensing unit 1 is a capacitive touch sensing unit, the at least two touch sensing sheets 11 are capacitive touch sensing electrode sheets, and since the bearing plate 5 is close to the inner surface of the earphone handle housing 31, when a finger of a user touches a position of the outer surface of the earphone handle housing 31 corresponding to a certain touch sensing sheet 11, the finger of the user and the touch sensing sheet 11 are capacitively coupled to enable the touch sensing sheet 11 to generate a touch sensing signal. Since the earphone handle housing 31 is made of an insulating material, the performance of the antenna body 2 is not affected.
The outer surface of one side of the earphone handle housing 31 may be provided with an input indication mark, for example, a touch indication pattern, for prompting the user to perform a touch input from the side. The carrier plate 5 is embodied as a housing inner surface close to the side of the earphone handle housing 31 where the input indication mark is provided. Wherein the outer surface of the earphone handle housing 31 refers to the housing outer side surface, i.e. the surface that can be viewed and contacted by the user, and the inner surface of the earphone handle housing 31 refers to the surface opposite to the outer surface of the earphone handle housing 31, i.e. the surface facing the elements inside the earphone handle housing 31.
In some embodiments, the at least two touch-sensitive sheets 11 and the antenna body 2 are disposed on the surface of the carrier plate 5 close to the earphone handle housing 31. That is, in some embodiments, the at least two touch sensing sheets 11 and the antenna body 2 are disposed on the same surface of the carrier plate 5, and particularly, disposed on a surface of the carrier plate 5 close to/facing the earphone handle housing 31. The surface of the carrier plate 5 close to/facing the earphone handle housing 31 is a surface close to/facing a side of the earphone handle housing 31 where an input indication mark is disposed. Therefore, both the at least two touch-sensitive sheets 11 and the antenna body 2 can be closer to the side of the earphone handle housing 31 where the input indication mark is disposed, so that both the touch-sensitive and the antenna radiation performance are better.
In some embodiments, the at least two touch sensing sheets 11 may be further disposed on an insulating plate (not numbered) at intervals, and the insulating plate form the touch sensing unit 1, and then are disposed on the carrier plate 5. Obviously, the insulating plate can be omitted, and the areas of the carrier plate 5 for disposing the at least two touch sensor sheets 11 and the antenna body 2 are insulating areas.
Please refer to fig. 3, which is a schematic diagram of the touch sensing unit 1 and the antenna body 2 disposed on the carrier plate 5 in other embodiments. Wherein the carrier plate 5 includes two opposite surfaces, and in another embodiment, the at least two touch-sensitive sheets 11 and the antenna body 2 can be respectively disposed on the two opposite surfaces of the carrier plate 5.
For example, the antenna body 2 may be disposed on a surface of the loading plate 5 close to/facing the earphone handle housing 31, that is, a surface of the loading plate 5 close to/facing a side of the earphone handle housing 31 on which the input indication mark is disposed, and the at least two touch sensing pads 11 are disposed on a surface of the loading plate 5 away from the earphone handle housing 31, that is, a surface of the loading plate 5 away from the side of the earphone handle housing 31 on which the input indication mark is disposed. Since the whole of the loading plate 5 is disposed close to the inner surface of the earphone handle housing 31, that is, close to the inner surface of the side of the earphone handle housing 31 where the input indication mark is disposed, even if the at least two touch sensing pieces 11 are disposed on the surface of the loading plate 5 deviating from the earphone handle housing 31, the at least two touch sensing pieces 11 are still close to the earphone handle housing 31, thereby satisfying the sensitivity requirement of capacitive coupling with the finger of the user.
Obviously, in some embodiments, the at least two touch sensing sheets 11 may also be disposed on the surface of the carrier plate 5 close to/facing the earphone handle housing 31, and the antenna body 2 may be disposed on the surface of the carrier plate 5 facing away from the earphone handle housing 31.
When the at least two touch sensing sheets 11 and the antenna body 2 are respectively disposed on two opposite surfaces of the carrier plate 5, projections of the at least two touch sensing sheets 11 on the carrier plate 5 are surrounded by projections of the antenna body 2 on the carrier plate 5, and the projections of the at least two touch sensing sheets 11 on the carrier plate 5 and the projections of the antenna body 2 on the carrier plate 5 are not overlapped. That is, the aforementioned antenna body 2 surrounds the touch sensing unit 1, and the projection of the at least two touch sensing sheets 11 on the supporting board 5 may be surrounded by the projection of the antenna body 2 on the supporting board 5.
As shown in fig. 2, in some embodiments, the earphone handle 3 further includes an earphone handle bracket 32, the earphone handle bracket 32 is located in the earphone handle housing 31, and the carrier plate 5 provided with the at least two touch sensing sheets 11 and the antenna body 2 is located on the earphone handle bracket 32 and close to the inner surface of the earphone handle housing 31.
As shown in fig. 2, the wireless headset 100 further includes a circuit board 6, and a controller 7 and a radio frequency circuit 8 disposed on the circuit board 6, wherein the at least two touch sensor pads 11 are respectively connected to the controller 7 through corresponding electrical connectors J1 for implementing a touch sensing function, and an antenna feeding point F1 of the antenna body is connected to the radio frequency circuit 8 through a radio frequency connector J2 for implementing transceiving of an antenna radio frequency signal.
The electrical connector J1 may be an FPC (Flexible printed circuit) board, a conductive wire, or the like, and the radio frequency connector J2 may be a feed spring, or an FPC board, a conductive wire, or the like.
When a finger of a user touches a position, corresponding to a certain touch sensing sheet 11, on the outer surface of the earphone handle housing 31, the finger of the user and the touch sensing sheet 11 will be capacitively coupled, so that the touch sensing sheet 11 generates a touch sensing signal, and the controller 7 is configured to receive the touch sensing signal.
When the fingers of the user slide along the length direction of the earphone handle in the area of the outer surface of the earphone handle housing 31 corresponding to the at least two touch sensing pieces 11, that is, the arrangement direction of the at least two touch sensing pieces 11, the at least two touch sensing pieces 11 will successively generate touch sensing signals. The controller 7 receives the touch sensing signals generated by the different touch sensing sheets 11 successively, determines the sliding direction of the user according to the successively received touch sensing signals, and executes corresponding functions/operations.
For example, when it is determined that the user's slide direction is to slide in the earphone handle housing 31 from top to bottom, i.e., from the direction close to the earpiece 4 to the direction away from the earpiece 4, then the volume reducing operation may be controlled to be performed, when it is determined that the user's slide direction is to slide in the earphone handle housing 31 from bottom to top, i.e., from the direction away from the earpiece 4 to the direction close to the earpiece 4, then the volume reducing operation may be controlled to be performed, and so on.
The controller 7 may include a plurality of pins, each pin is connected to a corresponding touch sensing sheet 11 through a corresponding electrical connector J1, and each pin forms a corresponding relationship with the touch sensing sheet 11 connected thereto. The controller 7 may determine the touch sensing strip 11 currently generating the touch sensing signal according to the pin receiving the touch sensing signal, and thus may determine the touch sensing strip 11 sequentially generating the touch sensing signal according to the pin sequentially receiving the touch sensing signal, and may further determine an order in which the user touches the touch sensing strips 11, so as to obtain a sliding direction of the user.
In some embodiments, when the controller 7 receives only one touch sensing signal within a preset time (e.g., within 2 seconds), it determines that a single-click operation occurs, and according to a pin receiving the touch sensing signal, it may determine the touch sensing sheet 11 currently generating the touch sensing signal, and according to a preset corresponding relationship between a single touch sensing sheet 11 and a function operation, execute a corresponding function.
For example, the controller 7 controls to perform the operation of switching to the previous head when receiving only the touch sensing signal generated by the topmost touch sensing piece 11, that is, the touch sensing piece 11 closest to the earpiece 4, within a preset time, and the controller 7 controls to perform the operation of switching to the next head when receiving only the bottommost touch sensing piece 11, that is, the touch sensing piece 11 farthest from the earpiece 4, within a preset time, and so on.
Here, the corresponding operations of the slide touch and the single-click touch are not limited to the above examples.
The rf circuit 8 may include an rf source (not shown) and a matching circuit (not shown), and the rf source is connected to the antenna feeding point F1 of the antenna body 2 through the matching circuit and an rf connector J2 in sequence to provide a feeding signal to the antenna body 2.
In some embodiments, each electrical connection J1 connected to the touch-sensitive sheet 11 is further connected in series with a high-frequency inductor, and each touch-sensitive sheet 11 is connected to the controller 7 through a corresponding electrical connection J1 connected in series with a high-frequency inductor. The high-frequency inductor is an inductor which only has a function of blocking high-frequency alternating current and is also called a high-frequency choke coil.
Therefore, each touch sensing sheet 11 is connected to the controller 7 through the electrical connector J1 serially connected with a high frequency inductor, so that the path of the induced current return of the antenna body 2 coupled to the touch sensing sheet 11 can be blocked, and the coupling effect on the antenna body 2 can be reduced.
As shown in fig. 2, the earphone handle bracket 32 substantially divides the receiving space of the earphone handle housing 31 into a first receiving space S1 and a second receiving space S2, and the carrier plate 5 and the circuit board 6 are respectively disposed at two sides of the earphone handle bracket 32 and respectively located in the first receiving space S1 and the second receiving space S2.
In some embodiments, the carrier board 5 is disposed parallel to the circuit board 6, and the distance between the carrier board 5 and the circuit board 6 is a predetermined distance.
In some embodiments, the preset distance may be 1.9mm (millimeters). Therefore, the distance between the carrier plate 5 and the circuit board 6 is set to be a preset distance, for example, 1.9mm, so that the feeding path of the antenna body 2 can meet the requirement.
In some embodiments, the carrier board 5 is an FPC board (flexible circuit board), and the carrier board 5 is fixed to one side surface of the earphone handle holder 32.
In other embodiments, the carrier plate 5 and the earphone handle holder 32 may be a unitary structure, i.e. the carrier plate 5 may be part of the earphone handle holder 32.
In some embodiments, the antenna body 2 may be an LDS antenna formed on the carrier board 5 by a laser technology. The LDS antenna is a metal antenna pattern directly plated on the carrier board 5 by a laser technology.
In some embodiments, as shown in fig. 1, the antenna body 2 further includes a fourth antenna segment 24 in a bent shape, and the fourth antenna segment 24 is connected to an end of the first antenna segment 21 away from the second antenna segment 22. The fourth antenna segment 24 may be formed by bending and extending an end of the second antenna segment 21 away from the second antenna segment 22.
As shown in fig. 1, after the end of the first antenna segment 21 away from the second antenna segment 22 extends to the other side of the at least two touch sensing sheets 11 for a first distance, it extends to the second direction for a second distance, so as to form an "L" -shaped fourth antenna segment 24.
Wherein the first distance is smaller than the width of the touch sensing sheet 11. The width of the touch sensing sheet 11 refers to a dimension of the touch sensing sheet 11 perpendicular to the arrangement direction of at least two touch sensing sheets 11.
Thus, the antenna body 2 partially surrounds the touch sensing unit 1 at the end of the earphone handle 3 remote from the earpiece 4.
In some embodiments, the width of each touch-sensitive sheet 11 may be 1mm, and the length of each touch-sensitive sheet 11 may be designed as desired. The length of the touch sensing sheet 11 may be a dimension parallel to the arrangement direction of at least two touch sensing sheets 11.
Wherein, the lengths of the at least two touch sensing sheets 11 may be the same. In other embodiments, the lengths of the at least two touch-sensitive sheets 11 may be different, or the lengths of at least some of the touch-sensitive sheets 11 may be different.
The wireless earphone 100 further includes a charging interface 9 disposed at an end of the earphone handle 3 away from the earphone 4.
The end of the first antenna section 21 remote from the second antenna section 22, i.e. close to the charging interface 9.
