Description

Headphones and headphone modules Technical Field

[0001] This application belongs to the field of headphone technology, specifically relating to a headphone and a headphone module. Background Technology

[0002] In related technologies, open-back headphones require separating the acoustic and hardware components to achieve functionality and balanced weight distribution, with the two parts connected by a flexible rubber beam. To achieve electrical connection between the acoustic and hardware components, a flexible circuit board needs to be inserted within the flexible rubber beam, with its two ends electrically connected to the acoustic and hardware components respectively. However, because the flexible circuit board has a certain width, inserting it within the flexible rubber beam results in a larger beam width, which is detrimental to headphone miniaturization. Summary of the Invention

[0003] This application aims to provide an earphone and an earphone module that at least solves the problem that the flexible circuit board has a certain width, so inserting the flexible circuit board inside the flexible rubber beam will result in a large width of the flexible rubber beam, which is not conducive to the miniaturization of the earphone.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide an earphone, including a first housing, a second housing, a connecting member, a circuit board, a speaker, and a flexible conductive member; both ends of the connecting member are connected to the first housing and the second housing, respectively; the circuit board is disposed within the first housing; the speaker is disposed within the second housing; the flexible conductive member passes through the connecting member, and the number of flexible conductive members is at least two, with at least two flexible conductive members stacked, and each flexible conductive member includes at least two wires arranged in parallel, with both ends of the wires electrically connected to the circuit board and the speaker, respectively.

[0006] Secondly, this application provides an earphone module, including a battery compartment and earphones, wherein the earphones are earphones according to any of the above-mentioned technical solutions, and the earphones are disposed inside the battery compartment.

[0007] In embodiments of this application, the earphone further includes a flexible conductive component, which is disposed within a connecting component, thereby enabling the installation and support of the conductive component through the connecting component. The flexible conductive component includes at least two parallel wires, with both ends of the wires electrically connected to a circuit board and a speaker, respectively. The circuit board can supply power to the speaker through the flexible conductive component, and the circuit board can also control the speaker through the flexible conductive component. Compared to using a single flexible circuit board, stacking at least two flexible conductive components occupies less space in the width direction, allowing the width of the connecting component to be reduced accordingly. This facilitates the miniaturization of the connecting component, which in turn facilitates the miniaturization of the earphone, resulting in a more refined earphone design.

[0008] The number of flexible conductive components is at least two, and the stacking of at least two flexible conductive components increases the thickness of the flexible conductive components, giving them higher rigidity. During the assembly of the headphones, due to the higher rigidity of the flexible conductive components, it is easier to insert them into the connecting components, and the speed and efficiency of inserting them into the connecting components are faster and more efficient. This simplifies the insertion process of the flexible conductive components, reduces the assembly difficulty of the flexible conductive components, and improves the convenience of assembling the flexible conductive components.

[0009] Since the headphone module includes headphones based on any of the above-mentioned technical solutions, the headphone module possesses all the beneficial effects of headphones based on any of the above-mentioned technical solutions.

[0026] The following describes, with reference to Figures 1 to 8, an earphone 100 and an earphone module according to embodiments of the present application.

[0027] As shown in Figures 1 and 2, an earphone 100 according to some embodiments of this application includes a first housing 110, a second housing 120, a connecting member 130, a circuit board 140, a speaker 150, and a flexible conductive member 160. The two ends of the connecting member 130 are respectively connected to the first housing 110 and the second housing 120. The circuit board 140 is disposed inside the first housing 110. The speaker 150 is disposed inside the second housing 120. The flexible conductive member 160 passes through the connecting member 130. There are at least two flexible conductive members 160, and the at least two flexible conductive members 160 are stacked. The flexible conductive member 160 includes at least two parallel wires 164, and the two ends of the wires 164 are electrically connected to the circuit board 140 and the speaker 150, respectively.

[0028] In this embodiment, the earphone 100 includes a first housing 110, a second housing 120, and a connecting component 130. Both ends of the connecting component 130 are connected to the first housing 110 and the second housing 120 respectively, thereby connecting the first housing 110 and the second housing 120 into a single unit, improving the integrity of the earphone 100 and making it more convenient for the user to wear it. The earphone 100 also includes a circuit board 140 and a speaker 150. The circuit board 140 is disposed within the first housing 110, and the speaker 150 is disposed within the second housing 120, achieving the installation and protection of the circuit board 140 and the speaker 150, and improving the stability of the circuit board 140 and the speaker 150 during operation. The earphone 100 also includes a flexible conductive component 160, which is inserted into the connecting component 130, thereby enabling the installation and support of the conductive component through the connecting component 130. The flexible conductive component 160 includes at least two parallel wires 164, with the two ends of the wires 164 electrically connected to the circuit board 140 and the speaker 150, respectively. The circuit board 140 can supply power to the speaker 150 through the flexible conductive component 160, and the circuit board 140 can control the speaker 150 through the flexible conductive component 160. The number of flexible conductive components 160 is at least two, and the stacking of at least two flexible conductive components 160 increases the thickness of the flexible conductive components 160, giving them higher rigidity. During the assembly of the earphone 100, because the flexible conductive components 160 have higher rigidity, it is easier to insert them into the connecting component 130, and the speed and efficiency of inserting them into the connecting component 130 are faster and more efficient. This simplifies the insertion process of the flexible conductive components 160, reduces the assembly difficulty of the flexible conductive components 160, and improves the convenience of assembling the flexible conductive components 160.

[0029] Compared to a single flexible circuit board, stacking at least two flexible conductive components 160 occupies less space in the width direction, thereby reducing the cost of the prosthesis used in at least the connecting component 130 (a circular prosthesis is less expensive than a flat one). Furthermore, because the at least two flexible conductive components 160 occupy less space in the width direction, the width of the connecting component 130 can also be reduced, facilitating miniaturization of the connecting component 130 and consequently, miniaturization of the earphone, resulting in a more refined appearance for the earphone 100.

[0030] Compared to a wire harness composed of multiple wires 164 arranged arbitrarily, where at least two flexible conductive components 160 are stacked, there is no need to organize or separate the wire harness during wiring, and there is no need to individually wire the multiple wires 164 of the wire harness group. This simplifies the wiring process of the earphone 100, reduces the probability of errors during the wiring process of the earphone 100, and thus improves the assembly efficiency and yield of the earphone 100.

[0031] Furthermore, the earphone 100 also includes a battery disposed within the first housing 110 and electrically connected to the circuit board 140.

[0032] According to some embodiments of this application, as shown in Figures 2 and 3, the connecting component 130 is provided with a first hole 132, which extends from the first housing 110 to the second housing 120. The flexible conductive component 160 passes through the first hole 132, and the cross-section of the first hole 132 is circular. In other embodiments, the cross-section of the first hole 132 may also be other shapes, such as square, elliptical, trapezoidal, etc., which are not specifically limited in this application.

[0033] In this embodiment, the connecting component 130 is provided with a first hole 132, which extends from the first housing 110 to the second housing 120. The flexible conductive component 160 passes through the first hole 132, thereby realizing the installation and fixation of the flexible conductive component 160, reducing the probability of the flexible conductive component 160 breaking due to external stretching, and reducing the probability of the flexible conductive component 160 being scratched by external forces. The cross-section of the first hole 132 is circular. When manufacturing the connecting component 130, the prosthesis embedded in the connecting component 130 can be a cylinder, which reduces the cost required for the prosthesis embedded in the connecting component 130 and reduces the difficulty of removing the prosthesis, thereby reducing the manufacturing cost of the earphone 100, simplifying the manufacturing process of the earphone 100, and improving the manufacturing efficiency of the earphone 100.

[0034] Furthermore, the connecting component 130 is made of thermoplastic polyurethane (TPU) or silicone.

[0035] Furthermore, the connecting component 130 extends in a C-shape and cooperates with the first housing 110 and the second housing 120 to clamp the earphone 100 in the ear.

[0036] According to some embodiments of this application, as shown in Figures 3 and 4, the flexible conductive component 160 includes a conductive portion 166 and a wiring portion 168; the conductive portion 166 is located within the connecting component 130; the wiring portion 168 is connected to the conductive portion 166 and extends to the outside of the connecting component 130; wherein, the wiring portion 168 is bent relative to the conductive portion 166 (the wiring portion 168 is bent in the direction indicated by the arrow in Figure 3), and the bending directions of the wiring portions 168 of at least two flexible conductive components 160 are different.

[0037] In this embodiment, the flexible conductive component 160 includes a conductive portion 166 and a wiring portion 168. The conductive portion 166 is located within the connecting component 130, and the wiring portion 168 is connected to the conductive portion 166 and extends to the outside of the connecting component 130. The conductive portion 166 can be electrically connected to the circuit board 140 through the wiring portion 168, or the conductive portion 166 can be electrically connected to the speaker 150 through the wiring portion 168. The wiring portion 168 is bent relative to the conductive portion 166, and the bending directions of the wiring portions 168 of at least two flexible conductive components 160 are different, reducing the probability of mutual obstruction or interference between multiple wiring portions 168, simplifying the wiring process between the wiring portion 168 and the circuit board 140, and simplifying the wiring process between the wiring portion 168 and the speaker 150.

[0038] Specifically, there are two flexible conductive components 160. In one of the flexible conductive components 160, the wiring portion 168 of one flexible conductive component 160 is bent in a first direction relative to the conductive portion 166, and the wiring portion 168 of the other flexible conductive component 160 is bent in a second direction. The first direction and the second direction are two opposite directions, or the first direction and the second direction are at a certain angle, for example, the included angle between the first direction and the second direction is 60 degrees, 90 degrees or 120 degrees.

[0039] There are two flexible conductive components 160. In one of the flexible conductive components 160, the wiring portion 168 of one flexible conductive component 160 is bent in the first direction relative to the conductive portion 166, and the wiring portion 168 of the other flexible conductive component 160 extends in the same direction as the conductive portion 166, that is, the wiring portion 168 of the flexible conductive component 160 is not bent.

[0040] There are three flexible conductive components 160. Among the three flexible conductive components 160, the wiring portion 168 of the first flexible conductive component 160 is bent in a first direction relative to the conductive portion 166, the wiring portion 168 of the second flexible conductive component 160 is bent in a second direction, and the wiring portion 168 of the third flexible conductive component 160 extends in the same direction as the conductive portion 166.

[0041] There are four flexible conductive components 160. Among the four flexible conductive components 160, the wiring portion 168 of the first flexible conductive component 160 is bent in a first direction relative to the conductive portion 166, the wiring portion 168 of the second flexible conductive component 160 is bent in a second direction, the wiring portion 168 of the third flexible conductive component 160 is bent in a third direction, and the wiring portion 168 of the fourth flexible conductive component 160 is bent in a fourth direction. The first direction, the second direction, the third direction, and the fourth direction are arranged in sequence, and the two adjacent directions are at a certain angle, such as 30 degrees, 45 degrees, or 60 degrees.

[0042] Furthermore, the bending direction and bending angle of the wiring section 168 can be determined according to the layout of the circuit board 140.

[0043] The wiring portion 168 of the multiple flexible conductive components 160 is symmetrical with respect to the connecting component 130, or it may be asymmetrical with respect to the connecting component 130.

[0044] According to some embodiments of this application, as shown in Figures 3 and 4, the wiring portion 168 is soldered to the circuit board 140 or the speaker 150.

[0045] In this embodiment, the wiring part 168 is soldered to the circuit board 140 or the speaker 150, which further reduces the assembly difficulty of the earphone 100 and simplifies the wiring process of the earphone 100.

[0046] Specifically, the wiring section 168 is provided with a solder pad 165, which is soldered to the circuit board 140 or to the wiring terminal of the speaker 150.

[0047] Specifically, the flat and wide flexible circuit board is split into two or more narrow ones, which are then glued together so that they can pass through the first circular hole 132. The flexible circuit boards at both ends can be separated and folded, and then thermo-pressed or laser-welded to the circuit board 140 to complete the wiring.

[0048] According to some embodiments of this application, as shown in Figures 5 and 6, the earphone 100 further includes a connector 170, which is disposed on the circuit board 140 or the speaker 150, and the wiring portion 168 is inserted into the connector 170.

[0049] In this embodiment, connector 170 is disposed on circuit board 140 or speaker 150, and wiring part 168 is inserted into connector 170, which further reduces the assembly difficulty of headphone 100, simplifies the wiring process of headphone 100, and improves production efficiency.

[0050] Specifically, the wiring part 168 is inserted into the connector 170. Compared with soldering the wiring part 168 to the circuit board 140, the former has a higher yield and is easier to operate.

[0051] Specifically, a gold finger 169 is provided at the end of the wiring part 168 away from the conductive part 166, and the gold finger 169 is inserted into the connector 170.

[0052] Specifically, connector 170 is a zero insertion force (ZIF) socket.

[0053] According to some embodiments of this application, as shown in FIG7, the earphone 100 further includes an adhesive 180, which is disposed between two adjacent flexible conductive components 160 of at least two flexible conductive components 160, and the two adjacent flexible conductive components 160 are bonded together by the adhesive 180.

[0054] In this embodiment, two adjacent flexible conductive components 160 are bonded together with an adhesive 180, allowing multiple flexible conductive components 160 to be simultaneously inserted into the connecting component 130, thereby improving the insertion efficiency of the flexible conductive components 160. Furthermore, the bonding of two adjacent flexible conductive components 160 with the adhesive 180 allows multiple flexible conductive components 160 to form a whole, further improving the rigidity of the flexible conductive components 160, further simplifying the insertion process of the flexible conductive components 160, reducing the assembly difficulty of the flexible conductive components 160, and improving the ease of assembling the flexible conductive components 160.

[0055] Specifically, colloid 180 can be glue or double-sided tape.

[0056] According to some embodiments of this application, the flexible conductive component 160 is a flexible circuit board or a flexible ribbon cable.

[0057] In this embodiment, the flexible conductive component 160 is a flexible printed circuit (FPC). Because the flexible printed circuit is thinner (the thickness of a single flexible printed circuit is about 0.12 mm, and the thickness of a single wire 164 is about 0.3 mm), the lines of the flexible printed circuit are thinner (the thinnest can be 0.06 mm). The stacked flexible printed circuit occupies less space than wires 164 with the same number of lines. While ensuring that the cross-section of the prosthesis remains circular, there is no need to arrange the wires separately for soldering, which improves assembly efficiency and yield.

[0058] The flexible conductive component 160 is a flexible ribbon cable. Flexible ribbon cables are less expensive and can further reduce the cost of the earphone 100 while enabling power supply and signal transmission.

[0059] According to some embodiments of this application, as shown in Figures 4 and 5, the earphone 100 further includes a metal wire 190, which passes through the connecting member 130 and extends from one end of the connecting member 130 near the first housing 110 to one end of the connecting member 130 near the second housing 120. The metal wire 190 is used to maintain the shape of the connecting member 130.

[0060] In this embodiment, the metal wire 190 is threaded through the connecting member 130, extending from one end of the connecting member 130 near the first housing 110 to one end of the connecting member 130 near the second housing 120. The metal wire 190 can provide a certain rigidity to the connecting member 130, thereby enabling the connecting member 130 to maintain a certain shape more stably, and thus enabling the earphone 100 to be clamped more stably in the ear.

[0061] Specifically, the metal wire 190 is a shape memory alloy wire, such as titanium wire.

[0062] Specifically, the assembly process steps for the earphone 100 are as follows:

[0063] Injecting wire anti-pull buckles 192 into both ends of the metal wire 190;

[0064] The prosthesis is placed, and the prosthesis and the metal wire are arranged side by side at a 190° angle.

[0065] The prosthesis and wire 190 are coated with adhesive to form the connecting component 130;

[0066] The prosthesis is removed from the connecting component 130, and then the first hole 132 is formed on the connecting component 130 after the prosthesis is removed.

[0067] The flexible conductive component 160 is inserted into the first hole 132;

[0068] The flexible conductive component 160 is connected to the circuit board 140, and the flexible conductive component 160 is connected to the speaker 150.

[0069] According to some embodiments of this application, at least two flexible conductive components 160 have equal widths.

[0070] In this embodiment, at least two flexible conductive components 160 have the same width, so that two adjacent flexible conductive components 160 fit together more securely.

[0071] According to some embodiments of this application, as shown in FIG7, the width of at least two flexible conductive members 160 decreases from the flexible conductive member 160 located in the middle to the flexible conductive members 160 located on both sides.

[0072] The width of at least two flexible conductive components 160 decreases from the flexible conductive component 160 in the middle to the flexible conductive components 160 on both sides, so that the cross-section of the at least two flexible conductive components 160 after bonding is closer to a circle. This improves the rigidity of the flexible conductive components 160 and further reduces the space occupied by the flexible conductive components 160 in the width direction.

[0073] As shown in Figure 8, the headphone module according to an embodiment of this application includes a battery compartment 200 and a headphone 100. The headphone 100 is the headphone 100 of any of the above embodiments, and the headphone 100 is disposed within the battery compartment 200. Since the headphone module includes the headphone 100 of any of the above embodiments, the headphone module possesses all the beneficial effects of the headphone 100 of any of the above embodiments.

[0074] Specifically, the headphones 100 are clip-on headphones, ear-hook headphones, bone conduction headphones, neckband headphones, or over-ear headphones.

[0075] The structure of the aforementioned earphone 100 can also be applied to products where the main body is divided into two connected parts and an electrical connection needs to be formed between the two main bodies.

[0076] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
