Preferably, in connection with fig. 7, the microphone 100 is connected to the mobile terminal 400 in the protective case body 200 through the output plug 150, the output plug 150 is connected to the microphone body 110, and the coil spring wire 151 is disposed on the output plug 150.

In the embodiment, the microphone main body 110 is provided with the output plug 150, the output plug 150 is used for being connected with the mobile terminal 400 in the protective housing main body 200, and the output plug 150 is a standard 3.5mm audio plug, a Type-C plug, a micor usb plug or a plug of a lighting mobile phone, so that the microphone has the advantages of plug and play, no need of a battery, and normal use of the microphone caused by battery exhaustion.

In this embodiment, referring to fig. 7, a coil spring wire 151 is disposed on the output plug 150, and the coil spring wire 151 is retractable to control the movement of the microphone 100, and is electrically connected with the mobile terminal 400, so that the microphone 100 can rebound rapidly in a short time, is resistant to bending and abrasion, and can reduce the space occupied by the wire on the microphone 100 and keep the wire layout neat. For example, in the process of adjusting the position of the microphone 100, the distance from the microphone 100 to the tail end interface of the mobile terminal 400 may change, and if the distance from the microphone 100 to the tail end interface of the mobile terminal 400 becomes large, the coil spring wire 151 stretches and extends by itself, so that not only the connection stability between the microphone 100 and the mobile terminal 400 can be ensured, but also the wire on the output plug 150 can be ensured to be in a tight state, and the wire layout is reasonable and neat. If the coil spring wire 151 is not disposed on the output plug 150, the design of the wire on the output plug 150 needs to be set to the maximum value of the interface from the microphone 100 to the tail end of the mobile terminal 400, and if the microphone 100 is adjusted to the minimum value of the interface from the tail end of the mobile terminal 400 due to the position adjustment, the wire on the output plug 150 will drop and loose, and the wire mess will easily occur.

Preferably, the output plug 150 is a standard 3.5mm audio plug. For example, when the output plug 150 is a standard 3.5mm audio plug, the standard 3.5mm audio plug on the microphone main body 110 is inserted into the audio jack of the mobile terminal 400 in the protective housing main body 200, and meanwhile, the mobile terminal 400 is opened for video recording, and then plug and play, so that the microphone 100 does not need a battery, the operation is simple, convenient and practical, if the mobile terminal 400 is used for long-time video recording, the microphone 100 consumes much power, and meanwhile, the mobile terminal 400 also consumes much power, and at the moment, the mobile terminal 400 can be charged through a data line, namely, the video recording is charged while the normal video recording is not affected, therefore, the output plug 150 is the standard 3.5mm audio plug, the microphone can be guaranteed to be timely supplied for plug and play, and the charging jack of the mobile terminal is not occupied, the mobile terminal 400 can be timely charged under the condition of low electric quantity, and further, video recording is guaranteed to be normally carried out, if the microphone 100 is supplied through the battery (the condition that the microphone 100 is connected with the mobile terminal 400 through bluetooth), and normal video recording operation of the microphone 100 can be affected when the electric quantity of the battery is exhausted.

In one embodiment, in conjunction with fig. 6, the steering mechanism 120 includes: the microphone comprises a rotating shaft 123 and steering main bodies 121 arranged at two ends of the rotating shaft 123, wherein the rotating shaft 123 is sleeved on the microphone main body 110, and the microphone main body 110 rotates along the rotating shaft 123. Specifically, the steering main body 121 is provided with a set of hanging lugs 122, two hanging lugs 122 are respectively located at two ends of the rotating shaft 123, and the hanging lugs 122 are used for supporting and fixing the rotating shaft 1123. The microphone body 110 is used to capture high quality audio, enhance definition and sensitivity, and can improve the recording level, and the steering mechanism 120 can facilitate the pointing position of the microphone body 110. For example, when the pointing position of the microphone body 110 relative to the sound source needs to be adjusted, the microphone body 110 can be pulled to move toward the sound source, and at this time, the microphone body 110 rotates along the rotation axis 123, so that the microphone body 110 points to the direction of the sound source, and therefore, the steering mechanism 120 can ensure that the microphone 100 flexibly rotates, and is very suitable for on-site video recording.

In one embodiment, as shown in fig. 6, a rotation mechanism 140 is disposed between the steering mechanism 120 and the steering base 130, in this embodiment, the rotation mechanism 140 is disposed between the steering mechanism 120 and the steering base 130, and the steering mechanism 120 may rotate along the steering base 130 through the rotation mechanism 140, where the steering mechanism 120 is connected to the microphone main body 110, and therefore, the microphone main body 110 may change the pointing position through the rotation mechanism 140, the microphone main body 110 is used to capture high quality audio, enhance the sharpness and sensitivity, and may improve the recording level, and the rotation mechanism 140 may facilitate adjusting the pointing position of the microphone main body 110, for example, when it is required to adjust the pointing position of the microphone main body 110 relative to the sound source, the microphone main body 110 may be turned towards the sound source direction, so that the rotation mechanism 140 may ensure flexible rotation of the microphone main body 100, which is very suitable for on-site recording.

As described above, in the steering mechanism 120, the microphone main body 110 may rotate along the rotation axis 123, and at this time, the microphone main body 110 rotates along the radial direction of the rotation axis 123, so that the rotation of the microphone main body 110 along the axial direction of the rotation axis 123 cannot be achieved, and therefore, the rotation mechanism 140 can rotate the microphone main body 110 along the steering base 130, further achieve multi-directional adjustment of the direction of the microphone main body, achieve 360 ° rotation without dead angle, and enable the microphone 100 to move to the optimal sound receiving position, so as to obtain the optimal sound quality.
