Referring to fig. 1 to 4, the MIC anti-record assembly in the present embodiment may be applied to an acoustic enclosure, and includes components such as a MIC assembly 100, a base 200, a controller 600, and a first sensor 500.

The MIC assembly 100 includes a MIC130, the MIC130 having communication terminals 131. The base 200 is correspondingly provided with contact terminals 210. The controller 600 is used to control the operation of the MIC130, and the contact terminal 210 communicates with the controller 600.

Communication or interruption between the MIC130 and the controller 600 is associated with whether the first sensor 500 detects that a person is close to the MIC anti-recording assembly, so that the controller 600 issues a corresponding action instruction according to the close condition of the person, the occurrence of a skimming phenomenon is effectively avoided, and the information security and the use experience of a user are improved.

Specifically, when the first sensor 500 detects that a person approaches the MIC anti-recording assembly, the communication terminal 131 is in contact communication with the contact terminal 210, and the MIC130 is in communication with the controller 600, at which time the MIC anti-recording assembly can record a sound.

When the first sensor 500 detects that no one approaches the MIC anti-recording assembly, the communication terminal 131 is separated from the contact terminal 210, the MIC130 interrupts communication with the controller 600, and the MIC anti-recording assembly cannot perform a recording operation at this time.

In this embodiment, the first sensor 500 is an infrared sensor.

In some embodiments of the present application, the MIC anti-record assembly further comprises a transparent mounting portion 300 having a mounting cavity 310 formed therein for mounting the MIC assembly 100, the MIC assembly 100 being removably disposed within the mounting cavity 310 and movable in an axial direction of the mounting cavity 310.

When the first sensor 500 detects that no one is approaching the MIC anti-recording assembly, the MIC assembly 100 moves away from the base 200, the communication terminal 131 is separated from the contact terminal 210, and the MIC130 and the controller 600 are disconnected, so that the MIC assembly 100 cannot record.

In this embodiment, the contact and the separation between communication terminal 131 and contact terminal 210 are seen through transparent installation department 300, and like this, the user can clearly see the contact condition of communication terminal 131 and contact terminal 210 when using this MIC prevents recording subassembly to record, also is whether MIC130 is in the recording state, further effectively avoids the emergence of the phenomenon of surreptitious recording, improves user's information security and use experience.

In addition, MIC assembly 100 can be dismantled from installation cavity 310, and the dust on the clean MIC assembly 100 of being convenient for is favorable to improving the recording effect of MIC assembly 100.

The transparent mounting portion 300 may be made of transparent glass, which encloses a mounting space for mounting the MIC assembly 100.

The base 200 can be fixed in the lower part of the transparent installation part 300, the base 200 and the transparent installation part 300 are fixed in the sound box, and when the MIC assembly 100 is plugged, only the MIC assembly 100 is operated, so that the structure is reliable.

In some embodiments of the present application, referring to fig. 1-3, the MIC assembly 100 includes a cylindrical housing 110, and a stopper 120 is disposed on an outer circumferential wall of the housing 110. The installation cavity 310 includes a main cavity 311, and the shape of the main cavity 311 matches the shape of the housing 110 so that the housing 110 is inserted into the main cavity 311. Main cavity 311 is provided with a sliding cavity 312 along its axial direction, and sliding cavity 312 is matched with stopper 120, so that stopper 120 is inserted into sliding cavity 312. The main cavity 311 is provided with a stopper cavity (not shown) along a circumferential direction thereof, and a diameter of the stopper cavity is larger than a diameter of the main cavity 311. The chute cavity 312 extends downward from the top of the main cavity 311 to a stop cavity.

When the MIC assembly 100 is installed, the housing 110 is inserted into the main cavity 311 from top to bottom and moves down along the main cavity 311; the stopping portion 120 is inserted into the chute cavity 312 from top to bottom and moves downward along the chute cavity 312; when the stopping portion 120 moves downward to the stopping cavity, the stopping portion stops moving downward, the case 110 is horizontally rotated, the stopping portion 120 horizontally rotates together with the case 110, when the stopping portion 120 horizontally rotates into the stopping cavity, the stopping portion stops rotating, the stopping portion 120 is limited in the stopping cavity at this time, the MIC assembly 100 cannot be separated from the installation cavity 310, and the installation of the MIC assembly 100 is completed.

The stopper cavity limits the movement range of the stopper portion 120, specifically, along the axial direction of the main cavity 311, the height of the stopper cavity is greater than the height of the stopper portion 120, and the stopper portion 120 has a certain vertical movement space in the stopper cavity, and cannot be separated from the stopper cavity, that is, it is ensured that the MIC assembly 100 cannot be separated from the installation cavity 310.

When coil 220 is energized in the opposite direction, the magnetic poles of the magnetic field generated by coil 220 are opposite to the magnetic poles of electromagnet 140, and coil 220 and electromagnet 140 repel each other to drive MIC assembly 100 to move upward, i.e., drive MIC assembly 100 to move away from base 200, so as to separate communication terminal 131 from contact terminal 210.

In some embodiments of the present application, the MIC anti-record assembly further includes a driving part (not shown) for driving the base 200 to rotate in a horizontal plane.

When the MIC module 100 is installed, when the coil 220 is powered on and attracted to the electromagnet 140, and the stopping portion 120 is located in the slide cavity 312, the driving portion is started to drive the base 200 to rotate, for example, to rotate 90 °, and since the magnetic field generated by the coil 220 is attracted to the electromagnet 140, the base 200 drives the housing 110 to rotate, so that the stopping portion 120 horizontally rotates into the stopping cavity, and the installation of the MIC module 100 is completed.

The drive division can communicate with cell-phone APP, and the motion of user's accessible cell-phone APP control drive division, convenient to use.
