[0030] Referring to Figure 1 and Figure 2 , an in-ear detection capacitive FPC according to an embodiment of the first aspect of the present utility model includes an FPC main body 100. The FPC main body 100 is provided with a first capacitance detection part 110 and a second capacitance detection part 120. There are two first capacitance detection parts 110 and two second capacitance detection parts 120. The FPC main body 100 can be configured in a state where any one of the first capacitance detection parts 110 and any one of the second capacitance detection parts 120 are not in the same plane and cooperate through any one of the first capacitance detection parts 110 and any one of the second capacitance detection parts 120 to perform in-ear detection. Thus, 4 different detection combinations can be formed.

[0031] It can be imagined that in some embodiments, there may be one first capacitance detection part 110 and two second capacitance detection parts 120. Thus, two different detection combinations can be formed.

[0032] It can be imagined that in some embodiments, there may be three first capacitance detection parts 110 and two or more second capacitance detection parts 120. Thus, at least 6 different detection combinations can be formed.

[0033] The in-ear detection capacitive FPC provided by the present utility model can perform in-ear detection through the cooperation of any one of the first capacitance detection parts 110 and any one of the second capacitance detection parts 120. Among them, when the FPC main body 100 is arranged in the earphone, since the FPC main body 100 is a flexible circuit board, the FPC main body 100 can be deformed so as to be configured in a state where any one of the first capacitance detection parts 110 and any one of the second capacitance detection parts 120 are not in the same plane, which can reduce the probability of accidental touch. For example, when the earphone is placed on the table, the table will not simultaneously touch the first capacitance detection part 110 and the second capacitance detection part 120, avoiding accidental touch on the table. In addition, at least one first capacitance detection part 110 is provided, and at least two second capacitance detection parts 120 are also provided. Thus, at least two different detection combinations can be formed to adapt to various different ear types, improve the adaptability to various ear types, and improve the accuracy of in-ear detection.

[0034] In the specific implementation process, the FPC main body 100 is a flexible circuit board, and both the first capacitance detection part 110 and the second capacitance detection part 120 include the corresponding capacitance induction circuit on the FPC main body 100 and the part where the capacitance induction circuit is located.

[0035] Refer to Figure 1 and Figure 2 According to some embodiments of the present utility model, the FPC main body 100 has a first section 100a and a second section 100b. All the first capacitance detection parts 110 are arranged on the first section 100a, and all the second capacitance detection parts 120 are arranged on the second section 100b. Both the first section 100a and the second section 100b are continuous parts on the FPC main body 100. In this way, it is convenient for the staff to distinguish the first capacitance detection part 110 from the second capacitance detection part 120. Among them, when the FPC main body 100 is arranged in the earphone, the FPC main body 100 can be configured in a state where the first section 100a and the second section 100b are not in the same plane, so that any one of the first capacitance detection parts 110 and any one of the second capacitance detection parts 120 are not in the same plane.

[0036] Refer to Figure 1 and Figure 2 According to some embodiments of the present utility model, the first section 100a is arc-shaped, and two first capacitance detection parts 110 are arranged and correspondingly arranged at the left and right ends of the first section 100a. Thus, there is enough distance between the two first capacitance detection parts 110, and each first capacitance detection part 110 can also have a large enough area to ensure the detection ability of a single first capacitance detection part 110.

[0037] Of course, it should be noted that in the specific implementation process, the above-mentioned first capacitance detection unit 110 can also adopt other layout methods. For example, the above-mentioned first section 100a can be replaced with an S-shaped section, a C-shaped section, or an H-shaped section. Then, the two first capacitance detection units 110 are correspondingly arranged at the two ends with the farthest distance in the S-shaped section, C-shaped section, or H-shaped section.

[0038] Referring to Figure 1 and Figure 2 , according to some embodiments of the present invention, when the FPC main body 100 is disposed on the earphone, the first section 100a can be configured to be in a bent state, so that the two first capacitance detection units 110 are not in the same plane. Thus, the two first capacitance detection units 110 can better adapt to the ear shape, and the situation where objects other than the ears simultaneously contact the two first capacitance detection units 110 can be reduced.

[0039] Referring to Figure 1 and Figure 2 , according to some embodiments of the present invention, the second section 100b is arc-shaped, and two second capacitance detection units 120 are provided and correspondingly arranged at the left and right ends of the second section 100b. Thus, each second capacitance detection unit 120 can also have a sufficiently large area to ensure the detection ability of a single second capacitance detection unit 120. As Figure 1 shown, through the above settings, the two first capacitance detection units 110 are just correspondingly arranged on both sides of the connection line between the middles of the first section 100a and the second section 100b, and the two second capacitance detection units 120 are just correspondingly arranged on both sides of the connection line between the middles of the first section 100a and the second section 100b.

[0040] Referring to Figure 1 and Figure 2 , according to some embodiments of the present invention, when the FPC main body 100 is disposed on the earphone, the second section 100b can be configured to be in a bent state, so that the two second capacitance detection units 120 are not in the same plane. Thus, the two second capacitance detection units 120 can better adapt to the ear shape, and the situation where objects other than the ears simultaneously contact the two second capacitance detection units 120 can be reduced.

[0041] It can be imagined that in other embodiments, the FPC main body 100 can also be provided with more first capacitance detection units 110. For example, 3 or 4 first capacitance detection units 110 can be provided. At this time, these first capacitance detection units 110 can be arranged in shapes such as N-shaped and M-shaped.

[0042] It can be imagined that in some other embodiments, the FPC body 100 can also be provided with more second capacitance detection parts 120. For example, three or four second capacitance detection parts 120 can be provided, and these second capacitance detection parts 120 can be arranged around the circumference of the sound generating device 400.

[0043] Referring to Figure 1 , Figure 3 and Figure 4 , according to some embodiments of the present invention, a connection structure 140 for electrically plugging into the circuit board 500 is provided on the FPC body 100. Thus, the FPC body 100 can be quickly plugged into the circuit board 500 of the earphone through the connection structure 140, facilitating the assembly of the earphone.

[0044] Referring to Figure 1 , Figure 3 and Figure 4 , in the specific implementation process, the connection structure 140 can be set as a B2B connection structure 140 or a socket or plug such as type-c. Correspondingly, a matching plug or socket is also provided on the circuit board 500 of the earphone.

[0045] Referring to Figures 3 to 5 , an earphone according to the second aspect embodiment of the present invention includes the above-mentioned in-ear detection capacitance FPC. The earphone provided by the present invention adopts the above-mentioned in-ear detection capacitance FPC, which can reduce the probability of false touch, adapt to various different ear shapes, improve the adaptability to various ear shapes, and improve the accuracy of in-ear detection.

[0046] Referring to Figure 3 and Figure 4 , according to some embodiments of the present invention, the above-mentioned earphone includes a front shell 200, a rear shell 300, a sound generating device 400 and a circuit board 500. The front shell 200 and the rear shell 300 enclose an installation cavity. The circuit board 500 is installed on the rear shell 300, and the sound generating device 400 is located in the installation cavity. Among them, the first capacitance detection part 110 is arranged on the front side of the sound generating device 400, the second capacitance detection part 120 is arranged around the circumference of the sound generating device 400, and the FPC body 100, the sound generating device 400 and the circuit board 500 are electrically connected. With the above arrangement, the FPC body 100 can better adapt to various different ear shapes and improve the adaptability to various ear shapes.

[0047] Referring to Figure 3 and Figure 4, specifically, the FPC main body 100 is located in the installation cavity. The first capacitance detection part 110 is pressed and attached to the inner wall of the front side of the front shell 200 by the sound generating device 400, and the second capacitance detection part 120 is pressed and attached to the circumferential inner wall of the front shell 200. Thus, the first capacitance detection part 110 and the second capacitance detection part 120 can be stably fixed on the earphone, and the first capacitance detection part 110 and the second capacitance detection part 120 can perform ear-in detection more accurately and sensitively.

[0048] Among them, a bracket 600 is installed circumferentially on the sound generating device 400. The sound generating device 400 presses and attaches the second capacitance detection part 120 to the circumferential inner wall of the front shell 200 through the bracket 600.

[0049] Refer to Figure 3 and Figure 4 , the surface of the front shell 200 that abuts and fits against the first capacitance detection part 110 is a curved surface, and the surface of the front shell 200 that abuts and fits against the second capacitance detection part 120 is a curved surface. Through the above settings, each first capacitance detection part 110 and each capacitance detection part 120 can be bent, so as to better adapt to various different ear shapes, improve the adaptability to various ear shapes, and improve the accuracy of ear-in detection.

[0050] It should be noted that in some other embodiments, the FPC main body 100 can be arranged inside the front shell 200. Specifically, the front shell 200 can include an inner shell and an outer shell sleeved outside the inner shell. The FPC main body 100 is located between the outer shell and the inner shell, and the FPC main body 100 is clamped by the cooperation of the inner shell and the outer shell. Among them, the thickness of the outer shell is relatively thin to improve the detection sensitivity of the first capacitance detection part 110 and the second capacitance detection part 120.

[0051] Refer to Figure 1 , Figure 3 and Figure 5 , in the specific implementation process, one end of the FPC main body 100 can extend into the ear-in part 210 of the front shell 200 of the earphone to form an installation part 130, and the first noise reduction element 700 is arranged on the installation part 130.

[0052] Refer to Figure 3 and Figure 4, according to some embodiments of the present utility model, the front shell 200 is provided with an ear insertion part 210. One end of the FPC main body 100 is inserted into the ear insertion part 210. The FPC main body 100 is provided with a first noise reduction element 700, and the first noise reduction element 700 is located inside the ear insertion part 210. A second noise reduction element 800 is provided on the circuit board 500. Wherein, the circuit board 500 is located in the rear shell 300. Thus, when the user wears the earphone, the first noise reduction element 700 is located on the side of the sound generating device 400 close to the ear, and the second noise reduction element 800 is on the outer side of the sound generating device 400 away from the ear. Therefore, through the first noise reduction element 700 and the second noise reduction element 800, the circuit board 500 can perform noise reduction processing on the noise on both the front and back sides of the sound generating device 400, thereby improving the noise reduction ability of the earphone.

[0053] Referring to Figures 3 to 5 , in some embodiments, the above earphone can be a wireless earphone. The circuit board 500 communicates wirelessly with a mobile phone, a tablet or other terminals, etc. through Wi - Fi, Bluetooth, etc. A battery 900 is configured in the earphone for power supply, or the earphone adopts wireless power supply.

[0054] Of course, it can be imagined that in some other embodiments, the above earphone can also be a wired earphone.

[0055] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0056] The above has described this embodiment in detail with reference to the drawings. However, the present utility model is not limited to the above - described embodiment. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present utility model.
