Technical Field

[0001] This utility model relates to the field of headphones, and more specifically, to a headphone cable with a microphone and headphones. Background Technology

[0002] Compared to wireless headphones, wired headphones typically offer a more stable and higher-quality audio experience because the signal is transmitted directly through a physical connection. For applications requiring precise synchronization, such as karaoke, live streaming, or gaming, wired headphones provide virtually no audio latency, ensuring the best user experience.

[0003] However, the microphone of existing limited-access headphones is located on one side of the headphone cord. When the headphones are worn, the microphone hangs down to one side of the face and is not directly facing the mouth. When speaking or singing, one needs to hold the headphone cord to position the microphone towards the mouth, which is inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a headphone cable and headphones with a microphone, addressing the issue that wired headphones require holding the microphone and pointing it at the mouth.

[0028] The microphone-equipped headphone cable of this invention can be applied to wired headphones, such as wired in-ear headphones, over-ear headphones, and ear-hook headphones, especially for headphones that require precise synchronization, such as those used for karaoke, gaming, and live video streaming.

[0029] like Figure 1 , Figure 2 The diagram shows a schematic of the structure of a headphone cable with a microphone provided in this embodiment of the present invention. The headphone cable with a microphone in this embodiment includes a connector 10, a control box 20, a microphone 30, a first cable 41, a second cable 42, a third cable 43, a fourth cable 44, and a fifth cable 45. The headphone cable with a microphone connects to an audio playback device (e.g., a mobile phone, computer, MP3 player, MP4 player, etc.) via the connector 10, and connects to two headphone heads 50 via the second cable 42 and the third cable 43, respectively. The connector 10 supports both headphones and a microphone; specifically, the connector 10 can be a four-segment plug, a USB plug, a Lightning plug, or a USB-C plug. The microphone 30 is used to convert ambient sound into electrical signals. The headphone heads 50 can be in-ear headphones, over-ear headphones, or ear-hook headphones. The first cable 41, the second cable 42, the third cable 43, the fourth cable 44, and the fifth cable 45 are all wires with an insulating layer (and are elastic). In practical applications, the aforementioned connector 10, microphone 30, first cable 41, and earphone head 50 can all adopt conventional structures in the art, and will not be described in detail here.

[0030] The first cable 41 is connected between the connector 10 and the control box 20. The second cable 42 and the third cable 43 are respectively led out from the control box 20, that is, the second cable 42 and the third cable 43 are respectively connected between the control box 20 and an earphone 50. The fourth cable 44 is fixedly connected between the second cable 42 and the microphone 30. The fifth cable 45 is fixedly connected between the third cable 43 and the microphone 30. In this embodiment, at least one of the second cable 42, the third cable 43, the fourth cable 44 and the fifth cable 45 is provided with an elastic connection part. The elastic connection part allows the microphone 30 to be placed against the face when worn. That is, when the two earphones 50 are worn on the human ear, the elastic connection part on the second cable 42, the third cable 43, the fourth cable 44 and / or the fifth cable 45 pulls the microphone 30 with its elastic restoring force, so that the microphone 30 is placed against the face, especially near the mouth, such as below the mouth, thereby making the sound collected by the microphone 30 clearer.

[0031] The control box 20 houses a control circuit board, which may integrate circuits for adjusting the playback of the earphone 50 (e.g., on / off, pause, volume adjustment), and circuits for controlling the microphone 30 to turn on and off. The first cable 41 includes a first wire for electrically connecting the control circuit board to the connector 10. The second cable 42 and the third cable 43 each include a second wire for electrically connecting the earphone 50 to the control circuit board. The fourth cable 44 includes a third wire for electrically connecting the microphone 30 to the control circuit board. Through the first, second, and third wires, audio signals can be transmitted between the connector 10, the earphone 50, and the control circuit board, thereby enabling audio playback from the earphone 50 and sound acquisition from the microphone 30. Specifically, the mechanical and circuit structures of the control circuit board, and the electrical connection structures between the control circuit board and the connector 10, microphone 30, and earphone 50, can all adopt conventional solutions in the art, and will not be elaborated further here.

[0032] In a specific implementation, the fifth cable 45 may also have a third wire that electrically connects the microphone 30 to the control circuit board.

[0033] The aforementioned headphone cable with microphone has an elastic connector on the cable connecting the headphone head 50 or the microphone 30. When the headphones are worn, the elastic connector can pull the microphone to the face, allowing for convenient voice capture without holding the headphones.

[0034] In one embodiment of this invention, a portion of the third conductor passes through the second cable 42 and is electrically connected to the control circuit board inside the control box 20. Specifically, the portion of the second cable 42 connecting the fourth cable 44 and the control box 20 includes both the second and third conductors. This structure reduces exposed cables and simplifies the overall design. Of course, in practical applications, the third conductor in the fourth cable 44 can also be connected to the control box 20 via a separate wire independent of the second cable 42.

[0035] Specifically, the elastic connection portion on any one of the second cable 42, the third cable 43, the fourth cable 44, and the fifth cable 45 is composed of a cable coiled into a spring shape. Those skilled in the art will understand that the aforementioned coiled cable constitutes a tension spring, which can generate an elastic restoring force after being stretched. Furthermore, due to the cable material, its elastic restoring force is relatively small, for example, it can be 0.1-2 Newtons. It is sufficient to simply pull the microphone 30 to be placed against the face, particularly to position the microphone 30 near the mouth, for convenient voice pickup.

[0036] In one embodiment of this utility model, the second cable 42 and the fourth cable 44 are fixedly connected by a first fixing part 421 (i.e., the second cable 42 between the first fixing part 421 and the control box 20 simultaneously contains a second conductor and a third conductor), so that the end of the fourth cable 44 cannot slide along the length direction of the second cable 42. The third cable 43 and the fifth cable 45 are fixedly connected by a second fixing part 431, so that the end of the fifth cable 45 cannot slide along the length direction of the third cable 43, and when the fifth cable 45 contains a third conductor, the third cable 43 between the second fixing part 431 and the control box 20 simultaneously contains a second conductor and a third conductor. The aforementioned first fixing part 421 can be integrally formed with the second cable 42 and the fourth cable 44 (e.g., injection molded integrally) or fixed together by means of snap-fit ​​or the like. Similarly, the second fixing part 431 can be integrally formed with the third cable 43 and the fifth cable 45 (e.g., injection molded integrally) or fixed together by means of snap-fit ​​or the like. In practical applications, the distance between the first fixing part 421 and the second fixing part 431 and the earphone head is about 4-12cm.

[0037] The elastic connection includes a first elastic connection 441 located on the fourth cable 44 and a second elastic connection 451 located on the fifth cable 45. Specifically, the first elastic connection 441 is located between the microphone 30 and the first fixing part 421, and the second elastic connection 451 is located between the microphone 30 and the second fixing part 431. When the first elastic connection 441 and the second elastic connection 451 are in their fully retracted state, the distance between the first fixing part 421 and the second fixing part 431 (when the fourth cable 44, the microphone 30, and the fifth cable are in a straight line) is less than the width of a human face (where the width of a human face refers to the distance from the left cheek to below the lips and then to the right cheek), for example, 8-20 cm. Thus, when the earphone head 50 is worn on the ear, the first elastic connection 441 and the second elastic connection 451 can pull the microphone 30 from both sides. Under the combined force of the pull and the microphone 30's own weight, the microphone 30 is positioned close to the lower part of the mouth, facilitating speech pickup and maintaining microphone stability.

[0038] Specifically, the first elastic connection 441 is formed by at least a portion of the fourth cable 44 coiled into a spring shape, and the second elastic connection 451 is formed by at least a portion of the fifth cable 45 coiled into a spring shape. This structure simplifies the connection between the microphone 30 and the second cable 42 and the third cable 43. Of course, in practical applications, the first elastic connection 441 and the second elastic connection 451 can also employ other structures, as long as they can pull the microphone 30 to be close to the mouth.

[0039] like Figure 4 As shown, in another embodiment of this utility model, the elastic connection part can also be provided on the second cable 42 and the fourth cable 44, that is, the elastic connection part includes a third elastic connection part 422 and a fourth elastic connection part 432, wherein the third elastic connection part 422 is located between the earphone head 50 and the first fixing part 421, and the fourth elastic connection part 432 is located between the earphone head 50 and the second fixing part 431. When the third elastic connection part 422 and the fourth elastic connection part 432 are in a fully retracted state, the distance between the earphone head 50 and the first fixing part 421 (or the distance between the earphone head 50 and the second fixing part 431) is less than the distance between the human ear (external ear canal) and the proximal end of the mouth, and the distance between the first fixing part 421 and the second fixing part 431 (the fourth cable 44, the microphone 30 and the fifth cable 45 are located in the same straight line) is 6-15cm. In this way, when the earphone head 50 is worn on the ear, the third elastic connection part 422 and the fourth elastic connection part 432 can respectively pull the fourth cable 44 and the fifth cable 45, which in turn drive the microphone upward, so that the microphone 30 is close to the mouth, making it easier for the microphone 30 to pick up voice and keep the microphone 30 stable.

[0040] Specifically, the third elastic connection portion 422 is formed by at least a portion of the second cable 42 coiled into a spring shape, and the fourth elastic connection portion 432 is formed by at least a portion of the third cable 43 coiled into a spring shape. This structure simplifies the connection structure between the earphone head 50 and the first fixing portion 421 and the second fixing portion 431. Of course, in practical applications, the third elastic connection portion 422 and the fourth elastic connection portion 432 can also adopt other structures, as long as the microphone 30 can be placed near the mouth.

[0041] like Figure 2 As shown, in one embodiment of this utility model, the microphone 30 includes a first housing 31 connected to a fourth cable 44, a second housing 32 connected to a fifth cable 45, and a microphone body (i.e., the electronic component part) installed in the first housing. The first housing 31 and the second housing 32 are detachably connected together by snap-fit, tight fitting, or magnetic attraction. Thus, when the microphone 30 is not in use, the first housing 31 and the second housing 32 can be separated, wrapped around the back of the neck, and then reassembled, thereby achieving a neckband and preventing the earpiece 50 from falling off during exercise. Furthermore, the above structure also facilitates the application of a foam cover to the microphone 30, ensuring hygiene during use.

[0042] In one embodiment of this utility model, a microphone driver circuit is integrated on the control circuit board inside the control box 20. Correspondingly, the control box 20 has control buttons for triggering the microphone driver circuit to turn the microphone on and off. The microphone can be conveniently turned on and off in this way. The microphone driver circuit and control buttons described above can all adopt conventional solutions in the art, and will not be elaborated further here.

[0043] Combination Figure 3 As shown, in one embodiment of this utility model, the control box 20 contains a rechargeable battery, and the control circuit board is powered by the rechargeable battery. A charging circuit electrically connected to the rechargeable battery is integrated on the control circuit board. Correspondingly, the connector 10 includes a gripping portion 11 and an insertion portion 12, and the gripping portion 11 integrates a charging port 111 (the charging port 111 includes metal contacts for electrical connection to a power adapter or power bank, etc.). The first cable 41 includes a fourth wire for electrically connecting the charging port 111 to the charging circuit. With the above structure, the rechargeable battery in the control box 20 can be charged while the headphones are in use. The rechargeable battery, charging circuit, and charging port 111, etc., can all adopt conventional structures in the art, and will not be described in detail here.

[0044] This utility model also provides an earphone, including an earphone head and an earphone cable with a microphone as described above. Specifically, the earphone head can be an in-ear earphone head, an over-ear earphone head, an ear-hook earphone head, etc.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
