[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. As an audio output device, headphones have a wide range of applications; for example, they are essential for playing games, watching movies, and listening to music when connected to computers, mobile phones, CD players, etc.

[0003] Headphones typically include a microphone for voice calls, online gaming, live streaming, podcast recording, and short video recording. Current headphone microphones usually have only one microphone, using a single channel to transmit sound signals. Because all audio signals are transmitted and played through this single channel, the sound quality is relatively flat and monotonous. The soundstage of a single channel is relatively narrow, resulting in a thin, lacking spatial feel. Recorded audio files cannot create the sensation of sound coming from different directions, leading to a poor listening experience for the user. Utility Model Content

Detailed Implementation

[0024] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0025] Please see Figure 1 The illustration shows a microphone 100 with dual microphones, including two microphones and a connecting rod 30. The two microphones are movably connected to the top of the connecting rod 30. The two microphones include a dynamic microphone and a condenser microphone. The two microphones have different orientations. The two microphones are used for sound pickup and recording, and can provide two sound signals, so that the recorded audio has a stronger sense of layering and space.

[0026] Specifically, the sound recorded through the two microphones provides two-channel audio signals, resulting in better stereo sound, richer and more realistic sound quality, and a wider soundstage. The separation of the left and right channels accurately reproduces the mixing effect during recording, allowing listeners to more clearly distinguish the location and timbre of each sound source.

[0027] Specifically, the dynamic microphone uses electromagnetic induction to pick up sound, with a focus on capturing deep bass. It can withstand a high sound pressure level of 120dB and effectively filter ambient noise, thus preventing feedback. The condenser microphone has high sensitivity and can effectively capture the sounds of human voices and instruments. When used together, the two can achieve high-fidelity professional recording more effectively and can also record the left and right channels simultaneously.

[0028] The dynamic microphone is an omnidirectional microphone, and the condenser microphone is a directional microphone, mainly for picking up human voices.

[0029] Preferably, the top end of the connecting rod 30 is provided with a movable connecting component, which is used to mount the two microphones on the connecting rod 30 and to give the two microphones a predetermined tilt angle; The movable connection assembly includes a first connector 31 and a second connector 32. The first connector 31 is inserted into the top end of the connecting rod 30, and the second connector 32 is movably connected to the top end of the first connector 31 and has a predetermined rotation angle with the top connection point of the first connector 31 as the axis.

[0030] Preferably, the second connector 32 includes a cylindrical connecting spindle and two connecting arms, the two connecting arms being fixedly connected to the same side of the connecting spindle at a predetermined angle; The connecting spindle has a connecting groove on its side wall, which is used to connect the first connecting member 31; the two connecting arms and the connecting groove are located on opposite sides of the connecting spindle.

[0031] Specifically, in this embodiment, the included angle between the two connecting arms is 60 degrees, and the distance between the top ends of the two connecting arms is greater than the length of the connecting spindle, so that the two microphones have sufficient room to move.

[0032] Preferably, the first connector 31 has an upper part and a lower part, the lower part is a hollow cylinder, the upper part is a hollow cuboid, the front and rear side walls of the upper part have raised steps, the upper part extends into the connecting groove of the connecting spindle of the second connector 32 and is movably connected to the connecting spindle, the steps are used to limit the rotation angle of the connecting spindle; the upper part and the lower part of the first connector 31 are located on the same axis, and the upper part and the lower part of the first connector 31 are integrally formed.

[0033] Preferably, two microphones are movably connected to the top ends of the two connecting arms, and the directions of the two microphones are adjusted so that the two microphones have different angles to achieve different recording modes.

[0034] Specifically, the two connecting arms include a first connecting arm and a second connecting arm, and the two microphones include a first microphone 10 and a second microphone 20, wherein the first microphone 10 is movably connected to the top end of the first connecting arm, and the second microphone 20 is movably connected to the top end of the second connecting arm.

[0035] Specifically, in this embodiment, the two microphones have three different recording modes: Recording Mode 1: Zoom Recording Mode, please refer to [link / reference] Figure 2 The two microphones point in the same direction, meaning they are arranged parallel to each other. The zoom recording mode utilizes multiple omnidirectional microphones in conjunction with a beamforming algorithm to enhance sound from the target direction and suppress interference from other directions, enabling long-distance sound acquisition.

[0036] Recording Mode Two: XY Recording Mode, please refer to [link / reference]. Figure 3 The two microphones point inwards, meaning they point inwards between each other. In XY recording mode, the diaphragms of the two microphones should be as close as possible; the larger the angle between the two microphones, the stronger the stereo effect.

[0037] Recording Mode 1: Wide Stereo Recording Mode, please refer to [link / reference] Figure 4 The two microphones are pointed in opposite directions, that is, they point outwards from each other, forming a Y-shape. The wide stereo recording mode reproduces the spatial sense and layering of sound sources through a dual-channel format, utilizing the difference between the left and right channels to restore sound location and provide a better sense of space.

[0038] Preferably, the bottom end of the connecting rod 30 has a wire insertion interface, and the connecting spindles of the first connecting member 31, the second connecting member 32, the two connecting arms, and the connecting rod 30 all have through hollow wiring channels. The connecting cables of the two microphones pass through the wiring channels of the first connecting member 31, the second connecting member 32, the two connecting arms, and the connecting rod 30, and are connected to the wire insertion interface.

[0039] And, please see Figure 5 and Figure 6 The diagram illustrates a dual-microphone headset 200, comprising a headband 210, two earphone bodies 220, and a dual-microphone microphone 100 as described above. The two earphone bodies 220 are respectively disposed at both ends of the headband 210. The microphone 100 is detachably disposed on the outside of one of the earphone bodies 220. The earphone body 220 and the dual-microphone microphone 100 are connected by an earphone cable. The outside of the earphone body 220 is provided with a rotatable first connecting claw 221, and the end of the connecting rod 30 is disposed on the first connecting claw 221, allowing the microphone 100 to rotate within a predetermined range outside the earphone body 220.

[0040] Specifically, one end of the headphone cable is connected to the headphone body 220, and the other end is connected to the plug interface at the bottom of the microphone 100 with dual microphones.

[0041] Preferably, it also includes an external sound card 230, which has a first microphone 100 control button. The first microphone 100 control button includes a microphone 100 volume control knob, a microphone 100 mute button, and a mono / stereo switch button. The first microphone 100 control button is used to control the working mode of the microphone 100 with dual microphones.

[0042] And, please see Figure 7 The present invention illustrates a microphone device 300 with dual microphones, comprising a microphone stand 310 and a microphone 100 with dual microphones as described in any one of claims 1-6.

[0043] Specifically, the second connecting claw is movably connected to the support rod, allowing the microphone 100 to adjust its rotation angle within a predetermined range in order to adjust the pickup angle.

[0044] Preferably, it also includes a microphone controller 330, which is connected to the bottom plug-in interface of the microphone 100 with dual microphones via a microphone cable 320. The microphone controller 330 has a second microphone 100 control button and a recording storage device for storing sound information.

[0045] Specifically, the microphone controller 330 is also connected to an external recording device via a cable.

[0046] Specifically, the second microphone 100 control button is used to control the working mode of the microphone 100 with dual microphones. The second microphone 100 control button includes not only the microphone 100 volume control knob, microphone 100 mute button and mono / stereo switch button with the same functions as the first microphone 100 control button, but also a recording storage button to control whether the recording is stored in its own recording storage device or an external recording device.
