[0044] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and examples.
[0045] Please refer to Figures 1 to 6 The specific structure of the preferred embodiment of the present application is shown in the drawings, which is an external microphone device with Bluetooth, comprising a first connector 10 for plugging an intelligent terminal, further comprising a shell 20, the first connector 10 is installed on one end of the shell 20; the shell 20 is provided with a circuit board 21, a key triggering device 22, a microphone 23, a battery 24 and a Bluetooth module 25, the circuit board 21 is electrically connected to the key triggering device 22, the microphone 23, the battery 24 and the Bluetooth module 25; the circuit board 21 is provided with a control chip 26. Press or move the key triggering device 22 to switch the microphone device to the microphone 23 mode, Bluetooth mode or mute mode.
[0046] When using the external microphone device with Bluetooth, the first connector 10 is plugged into an electronic terminal device such as a computer, notebook, or mobile phone to achieve connection with the electronic terminal device. Furthermore, since the housing 20 contains a circuit board 21, a button trigger device 22, a microphone 23, a battery 24, and a Bluetooth module 25, when the button trigger device 22 is pressed or toggled, the microphone device is in microphone 23 mode or Bluetooth mode.
[0047] In microphone 23 mode, the microphone device, as the designated sound pickup device for electronic terminal devices, disables the original microphone function of these electronic terminal devices and replaces the original microphone of these electronic terminal devices with the external microphone device. After the microphone 23 of the external microphone device picks up the sound, it is transmitted to these electronic terminal devices through the first connector 10.
[0048] The external microphone device and these electronic terminal devices thus form a conferencing system. The new technology-based external microphone device has clearer sound pickup, and when combined with the external speakers built into these electronic terminal devices, this allows for better audio quality during remote conferences. This overcomes the issue of unclear audio during remote conferences without requiring replacement of the electronic terminal devices. Furthermore, the new technology-based external microphone device has a greater sound pickup range than the original microphones 23 built into these electronic terminal devices.
[0049] In Bluetooth mode, the microphone device realizes Bluetooth wireless connection with the Bluetooth headset through the Bluetooth module 25. As the designated sound pickup device of the Bluetooth headset, the microphone device will turn off the original microphone function of the Bluetooth headset, so that the external microphone device and the Bluetooth headset form a conference system. The external microphone device using new technology has a clearer sound pickup effect, and combined with the original in-ear, head-mounted, clip-on, and bone conduction speakers on the Bluetooth headset, better sound conversation effects can be achieved during remote meetings.
[0050] Among them, Figure 1 and Figure 2As shown, the microphone 23 includes a first microphone 231 and a second microphone 232, which are distributed on opposite sides of the shell 20. The opposite orientations can ensure that the first microphone 231 and the second microphone 232 pick up sounds in different directions, achieving a clearer sound pickup effect. In other embodiments, the number of microphones 23 can be more to achieve better omnidirectional sound pickup. More specifically, the first microphone 231 and the second microphone 232 are of the MIC_SPV71A0LR5H model, which is a full-directional microphone 23 with the characteristics of clear sound, good sound quality restoration, comfortable listening, high signal-to-noise ratio, low distortion, and low noise, and has a sound pickup distance of 10 meters.
[0051] The key triggering device 22 is an elastic pressing type mechanical key arranged on the side of the shell 20. In this embodiment, the key triggering device 22 is arranged beside the first microphone 231, and the key triggering device 22 and the side of the shell 20 have the same curvature to form a fitting with the shell 20 in an embedded manner, and the appearance is beautiful.
[0052] In order to adapt to different electronic terminal devices, the first connector 10 is a USB connector, a Tipy-C connector 11, or an Apple connector. It can also be other connector types on the market, which are not listed here. For example, Figure 5 As shown, the first connector 10 is provided with a cap 12, and the cap 12 is internally provided with a protective plug 13, which can protect the first connector 10 and prevent the cap 12 from falling off the first connector 10 when not in use.

Further comprising a signal converter 14, the signal converter 14 includes a converter shell 141, a plastic core 142, a conversion connector 143, and a connecting sleeve 144, one end of the conversion connector 143 is connected to the gold finger circuit board 113, the other end is fixedly connected to the circuit board 21 through the connecting sleeve 144, the plastic core 142 is integrally covered on the outer periphery of the conversion connector 143 and the gold finger circuit board 113, and the converter shell 141 is sleeved on the outer periphery of the plastic core 142.
[0054] As shown, Figure 5 and Figure 6As shown, the shell 20 comprises an outer shell 201 and an inner shell 202, the circuit board 21 is supported in the inner shell 202, and the outer shell 201 is wrapped outside the inner shell 202. The inner shell 202 is for example a rubber shell, which can provide adaptation and buffering for the circuit board 21 to improve service life, and the outer shell 201 is preferably a metal shell or a hard protective shell with anti-collision and drop resistance. The inner shell 202 is provided with a battery accommodating cavity 203, the side wall of the circuit board 21 is provided with a wire passing groove 211, the battery 24 is located at the back of the circuit board 21 and is installed in the battery accommodating cavity 203, and the wire of the battery 24 passes through the wire passing groove 211 to the front of the circuit board 21 for connection.
