Description

Technical Field

[0001] This utility model relates to the field of wired headphone technology, and more specifically, to a wired headphone with an external microphone module. Background Technology

[0002] With the widespread use of smartphones, tablets, and other mobile devices, headphones have become an indispensable part of people's daily lives. In particular, wired headphones with microphones still occupy an important position in specific scenarios (such as professional audio production, e-sports games, and high-fidelity music playback) due to their advantages over wireless headphones, such as lower cost, no need for charging, and stable connection.

[0003] Traditional wired headphones typically use a fixed microphone design, meaning the microphone is rigidly connected to the headphone cable or earpiece structure and is usually integrated into the splitter controller.

[0004] However, traditional wired headsets with microphones also have some problems in actual use: for example, traditional microphones usually only suppress airflow impact noise through physical openings or simple filters, which makes it difficult to completely eliminate popping noise. When used outdoors, the popping sound caused by wind noise or speaking too fast can easily affect the call quality. Secondly, the microphone lacks physical protection and is easily affected by saliva splashes or friction noise. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a wired headphone with an external microphone module to solve the problem that traditional wired headphones, which suppress airflow impact noise through physical openings or filters, are unable to completely eliminate the popping sound phenomenon.

[0006] The technical solution of this utility model is as follows: a wired earphone with an external microphone module, including a first earpiece, a second earpiece, a first earphone cable and a second earphone cable, wherein the first earphone cable is connected to the first earpiece and the second earphone cable is connected to the second earpiece;

[0007] It also includes a microphone unit and a mounting base. The first earphone cable includes a first connecting wire and a second connecting wire, which are respectively connected to the mounting base. The mounting base and the microphone unit are detachably connected. The microphone unit is covered with a pop filter.

[0008] Furthermore, it also includes an earphone plug and a controller, the earphone plug and the controller being connected by a signal data line, the signal data line being split into a first earphone cable and a second earphone cable via the controller.

[0009] Furthermore, the mounting base includes a first magnetic element and a first conductive post, and the microphone unit includes a second magnetic element and a second conductive post. The first magnetic element and the second conductive post are coaxially arranged, and the second magnetic element and the second conductive post are coaxially arranged. When the first magnetic element and the second magnetic element are in contact, the first conductive post and the second conductive post are electrically connected.

[0010] Furthermore, the mounting base includes a base and a clamping part. The clamping part is connected to the base via at least one torsion spring. The first torsion arm of the torsion spring abuts against the base, and the second torsion arm of the torsion spring abuts against the clamping part. A clamping space with a variable clamping distance is formed between the clamping part and the base. The torsion spring applies a preload force to the clamping part towards the base through an elastic restoring force. The clamping end face of the clamping part is provided with a first anti-slip tooth, and the base is correspondingly provided with a second anti-slip tooth. The first anti-slip tooth and the second anti-slip tooth are misaligned.

[0011] Furthermore, it also includes a signal processing circuit, which includes an analog switch U2, a magnetic induction chip U1, a first microphone MIC_1, and a second microphone MIC_2. The first microphone MIC_1 is connected to the audio output terminal MIC_OUT through the analog switch U2. The magnetic induction chip U1 is used to detect the magnetic coupling state of the second microphone MIC_2. The analog switch U2 is electrically connected to the magnetic induction chip U1. When the second microphone MIC_2 approaches the magnetic induction chip U1, the magnetic induction chip U1 generates a trigger signal and transmits it to the analog switch U2. The analog switch U2 receives the trigger signal, disconnects the connection between the first microphone MIC_1 and the audio output terminal MIC_OUT, and switches to the input channel of the second microphone MIC_2, so that the signal of the second microphone MIC_2 is output to the audio output terminal MIC_OUT.

[0012] Furthermore, the controller is provided with a volume up key and a volume down key, which protrude from the outer surface of the controller.

[0013] Furthermore, the headphone plug is a Type-C charging interface.

[0014] The advantages of this utility model based on the above solution are as follows:

[0015] (1) The present invention provides a wired earphone with an external microphone module. The microphone unit and the mounting base are connected by magnetic physical connection, which can realize plug and play. Secondly, this design can realize the disassembly of the microphone unit with one hand without the need for auxiliary tools.

[0016] (2) The present invention provides a wired earphone with an external microphone module. The microphone unit is covered with a pop filter to reduce the direct impact of airflow on the microphone and effectively filter the "pop sound" (such as the plosive sound of "p" and "b" syllables) generated by breathing airflow. Compared with traditional wired earphones, the wired earphone provided by the present invention can attenuate high-frequency noise while retaining the details of human voice, which is especially suitable for outdoor communication scenarios. In addition, the protective cover can be removed and cleaned to avoid the accumulation of dirt caused by long-term use and affect the sound reception effect. Attached Figure Description

[0027] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0028] To better understand this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate the present utility model:

[0029] Example 1

[0030] See Figures 1-2 As shown, Embodiment 1 of this utility model provides a wired earphone with an external microphone module, including a first earpiece 1, a second earpiece 2, a first earphone cable 3, a second earphone cable 4, a microphone unit 5, and a mounting base 6. The first earphone cable 3 is connected to the first earpiece 1, and the second earphone cable 4 is connected to the second earpiece 2. The first earphone cable 3 includes a first connecting wire 31 and a second connecting wire 32, which are respectively connected to the mounting base 6. The mounting base 6 and the microphone unit 5 are detachably connected, and the microphone unit 5 is covered with a pop filter protective cover 7.

[0031] Specifically, the mounting base 6 and the microphone unit 5 are magnetically coupled to achieve contact and conduction. The magnetic coupling automatically attracts and aligns the microphone unit 5 through the magnetic field, eliminating the need for mechanical alignment of traditional plug-in interfaces. Simply bring the microphone unit 5 close to the mounting base 6 to automatically attract and complete the connection, significantly improving ease of use. Moreover, with this design, only a lateral pulling force greater than the magnetic attraction force is needed to separate the microphone unit 5, eliminating the need for traditional threaded rotation or snap-on pressing operations.

[0032] Compared to the fixed embedded microphone of traditional wired headphones, the wired headphones provided in Embodiment 1 of this utility model allow users to flexibly remove the microphone unit 5 according to the needs of the scenario.

[0033] In this embodiment 1, the protective cover is a porous sponge. The protective cover can disperse airflow, preventing airflow from directly impacting the microphone capsule and reducing high-frequency noise caused by air vibration. At the same time, the physical barrier of the protective cover can reduce friction noise between airflow and the microphone shell.

[0034] Specifically, when syllables such as "p" and "b" are pronounced, the high-speed airflow ejected from the mouth flows to the surface of the protective sleeve, where it is absorbed and diffused by the porous material, avoiding direct impact on the microphone diaphragm and reducing the energy transfer of low-frequency popping sounds (popping sounds are essentially low-frequency pulsed airflow), thus preserving clear mid-frequency details of the human voice.

[0035] In this embodiment 1, the wired headphones with an external microphone module provided by this utility model embodiment 1 also include a headphone plug 8 and a controller 9. The headphone plug 8 and the controller 9 are connected by a signal data line 10. The signal data line 10 is split into a first headphone line 3 and a second headphone line 4 via the controller 9.

[0036] See Figure 3 and Figure 4 As shown, the mounting base 6 includes a first magnetic element 61 and a first conductive post 62, and the microphone unit 5 includes a second magnetic element 51 and a second conductive post 52. The first magnetic element 61 and the second conductive post 52 are coaxially arranged. When the first magnetic element 61 and the second magnetic element 51 are in contact, the first conductive post 62 and the second conductive post 52 are electrically connected.

[0037] Specifically, the first magnetic component 61 (ring magnet) and the first conductive post 62 are coaxially integrated in the mounting base 6, and the second magnetic component 51 (magnetic ring corresponding to the magnetic pole) and the second conductive post 52 are also coaxially integrated in the microphone unit 5, forming a nested structure with "magnetic ring on the outside and conductive post in the middle". The first magnetic component 61 and the second magnetic component 51 cooperate to be positioned by physical adsorption, and the first conductive post 62 and the second conductive post 52 contact each other to realize electrical signal transmission. The coaxial layout achieves a compact design.

[0038] See Figure 5 As shown, the mounting base 6 includes a base 63 and a clamping part 64. The clamping part 64 is connected to the base 63 via at least one torsion spring. The first torsion arm of the torsion spring abuts against the base 63, and the second torsion arm of the torsion spring abuts against the clamping part 64. A clamping space with a variable clamping distance is formed between the clamping part 64 and the base 63. The torsion spring applies a preload force to the clamping part 64 towards the base 63 through its elastic restoring force. The clamping end face of the clamping part 64 is provided with a first anti-slip tooth 641, and the base 63 is correspondingly provided with a second anti-slip tooth 631. The first anti-slip tooth 641 and the second anti-slip tooth 631 are staggered. This design facilitates clamping the mounting base 6 onto a collar.

[0039] SeeFigure 6 As shown in Embodiment 1, the wired headphones also include a signal processing circuit. The signal processing circuit includes an analog switch U2, a magnetic induction chip U1, a first microphone MIC_1, and a second microphone MIC_2. The first microphone MIC_1 is connected to the audio output terminal MIC_OUT through the analog switch U2. The magnetic induction chip U1 is used to detect the magnetic coupling state of the second microphone MIC_2. The analog switch U2 is electrically connected to the magnetic induction chip U1. When the second microphone MIC_2 approaches the magnetic induction chip U1, the magnetic induction chip U1 generates a trigger signal and transmits it to the analog switch U2. The analog switch U2 receives the trigger signal, disconnects the connection between the first microphone MIC_1 and the audio output terminal MIC_OUT, and switches to the input channel of the second microphone MIC_2, so that the signal of the second microphone MIC_2 is output to the audio output terminal MIC_OUT.

[0040] In this embodiment 1, the second microphone MIC_2 is located inside the microphone unit 5, and the analog switch U2, the magnetic induction chip U1, and the first microphone MIC_1 are located inside the mounting base 6.

[0041] To further illustrate this, Embodiment 1 of this utility model also provides a circuit connection diagram of the magnetic induction chip U1 and a circuit connection diagram of the analog switch U2, see [link to documentation]. Figure 7 and Figure 8 As shown.

[0042] In this embodiment 1, pin 2 of the magnetic induction chip U1 is connected to pin 6 of the analog switch U2. When the second microphone MIC_2 approaches the magnetic induction chip U1, the magnetic induction chip U1 generates a trigger signal and sends it to pin 6 of the analog switch U2 through its pin 2. The analog switch U2 receives the trigger signal and processes it. After signal processing, the analog switch U2 generates a control command, which is sent to the channel through pin 6 of the analog switch U2, causing the channel to switch to the second microphone MIC_2 and simultaneously turn off the second microphone MIC_1.

[0043] In this embodiment 1, the controller 9 is provided with a boost key 91 and a mute key 92, which protrude from the outer surface of the controller 9.

[0044] Specifically, headphone plug 8 is a Type-C charging port.

[0045] Example 2

[0046] Unlike Embodiment 1, Embodiment 2 provides a wired earphone with an external microphone module. The mounting base 6 and the microphone unit 5 are mechanically and electrically connected through a pin assembly. One of the mounting base 6 and the microphone unit 5 is provided with two jacks, and the other of the mounting base 6 and the microphone unit 5 is provided with two pins. The two pins and the two jacks are connected one-to-one so that the microphone unit 5 can be plugged into the mounting base 6.
