A second guide groove 136 extending in the axial direction of the housing 110 is formed on the inner surface of the knob 134, and a second guide protrusion 135 is provided on the outer circumferential surface of the top block 131. Therefore, the circular motion of the rotary handle 134 can be converted into the linear motion of the top block 131, so that the opening and closing of the radio disc 120 can be effectively controlled, and different functions of the recording device 100 can be further utilized.

The top block 131 moves linearly in the casing 110 along the inner wall of the casing 110 in the axial direction (for example, BC direction in fig. 2) (the moving direction is determined by the rotating direction of the rotary handle 134). When top block 131 moves in the direction of C → B, for example, the top of top block 131 abuts the end of rib 123, applying pressure thereto, causing rib 123 to expand against the pull of elastic ring 124; when the top block 131 moves in the direction B → C, for example, the pressure of the top block 131 on the end of the rib 123 disappears and the pulling force of the elastic ring 124 starts to act to gather the rib 123.

Specifically, the housing 110 is provided with a first guide groove spirally extending along the axial direction of the housing 110, and the top block 131 is provided with a first guide protrusion slidably fitted in the first guide groove.

In addition, the operation methods and operation steps of schemes 2 to 4 can be easily obtained from scheme 1, and the present invention is not described again.

Alternatively, referring to fig. 1 and 2, the radio disc 120 may be disposed at a first end of the housing 110 (e.g., a left end of the housing 110 in fig. 1), and the hinge ring 122 may be disposed on or adjacent to the first end of the housing 110. Therefore, the umbrella ribs 123 can rotate around the rotary shaft ring 122 to further control the opening and closing of the radio disc 120, so that different functions of the recording device 100 can be utilized.

In addition, the housing 110 may be provided with a limiting portion 101, and the rotary shaft ring 122 and the elastic ring 124 may be provided on an inner side of the limiting portion 101 (for example, a side of the limiting portion 101 facing the axis of the housing 110 in fig. 2), wherein the limiting portion 101 may be used to limit the positions of the rotary shaft ring 122 and the elastic ring 124, and at the same time, to prevent the rotary shaft ring 122 and the elastic ring 124 from coming off. The umbrella ribs 123 can rotate around the rotating shaft ring 122, and a plurality of umbrella ribs 123 arranged along the circumferential direction of the rotating shaft ring 122 at intervals can penetrate out of the limiting part 101 to support the umbrella cover 129, so that the opening and closing of the radio disc 120 can be further controlled under the combined action of the rotating shaft ring 122 and the elastic ring 124, and different functions of the recording device 100 can be utilized.

According to some embodiments of the present invention, a limiting portion 101 connected to the housing 110 may be disposed between each two adjacent ribs 123, and a plurality of limiting portions may be disposed on the housing 110 and arranged in a ring shape, the rotation shaft ring 122 and the elastic ring 124 may be disposed inside the limiting portion 101, the limiting portion 101 may include a side plate 103 and a top plate 106, the side plate 103 may be connected to the housing 110, and the top plate 106 may be connected to the side plate 103 and extend toward an inside of the side plate 103. Thereby facilitating the user to utilize different functions of the recording device 100 according to actual needs.

As shown in fig. 2 and 3, the stopper 101 may include a side plate 103 and a top plate 105, the side plate 103 may be connected to the housing 110, and the top plate 105 may be disposed at a free end of the side plate (refer to a second end 109 of the side plate in fig. 2) and extend toward an inner side of the side plate 103. For example, referring to FIG. 3, a first end 106 of side panel 103 may be coupled to housing 110 and top panel 105 may be disposed at a second end 109 of side panel 103 and extend inwardly. The rib 123 can be limited by the limiting part 101, so that the rib 123 can rotate around the rotating shaft ring 122 and can be normally opened and closed under the combined action of the rotating shaft ring 122 and the elastic ring 124, and different functions of the recording device 100 can be further utilized.

Alternatively, referring to fig. 7 and 8, each of the umbrella ribs 123 may include an umbrella rib body 128 and a driving handle 127, the driving handle 127 may be provided inside a fixed end 125 of the umbrella rib body 128 (refer to the fixed end 125 of the umbrella rib 123 in fig. 2 and 3) and extend in a direction perpendicular to the umbrella rib body 128, the umbrella rib body 128 may be provided with a rotation shaft fitting groove 102 for coupling with the rotation shaft ring 122, and a free end of the driving handle 127 may be provided with an elastic ring fitting groove 104 for coupling with the elastic ring 124.

Alternatively, the elastic ring fitting groove 104 may have an open groove shape that opens toward the rib main body 128.

For example, in the example of fig. 7, drive handle 127 may be perpendicular to rib body 128, and spring ring engagement groove 104 may be in the shape of an open groove that opens toward rib body 128 (e.g., the opening of spring ring engagement groove 104 is upward in fig. 7). The elastic ring matching groove 104 is used for matching with the elastic ring 124, thereby matching with the driving component to better control the opening and closing of the radio disc 120 so as to realize omnibearing recording or directional recording.

According to an embodiment of the present invention, the sound receiving surface 121 may be parabolic when the sound receiving panel 120 is in the unfolded position.

The shape of the paraboloid can be approximately similar to that of an umbrella cover in daily life, and the specific shape of the paraboloid and the specific position of the focus can be adaptively selected according to needs.

Referring to fig. 2, the recording microphone 139 may be located at the focus of the paraboloid when the radio 120 is in the deployed position. Thereby, the recording effect of the recording apparatus 100 can be ensured to some extent.

Preferably, when the radio disc 120 is unfolded, the sound receiving surface 121 is approximately paraboloid, sound in the range can be reflected and focused, and the position of the recording microphone 139 is exactly set at the focus of the paraboloid, so that the sound collected by the radio disc 120 can be recorded to the maximum extent. The radio 120 can be folded when not needed.

Specifically, the fact that the sound receiving surface 121 has a "parabolic shape" means that: the sound receiving surface 121 is a revolution surface formed by rotating a parabola around its symmetry axis, in which case, the focus of the parabola (or the focus of the parabola) is located on its symmetry axis, and the recording microphone 139 can be disposed at the focus of the parabola.

Preferably, the casing is cylindrical, the radio disc may be disposed at an end of the casing, and a symmetry axis of the parabola may coincide with a central axis of the casing.

It will be understood by those skilled in the art that the shape of the sound-receiving surface 121 may be other shapes, for example, the sound-receiving surface 121 may also be a spherical surface. The shape of the sound-receiving surface 121 is not particularly limited in the present invention, and the above description of the shape of the sound-receiving surface 121 is only one preferred embodiment of the present invention.

The recording apparatus 100 according to the embodiment of the present invention can realize omnidirectional recording or directional recording by adjusting the opening and closing of the radio disc 120 according to different recording environments and recording objects. The opening and closing form of the radio disc 120 is similar to that of an umbrella, but the principle of realizing the opening and closing mechanism of the umbrella-shaped radio surface 121 by rotating the rotary handle 134 is completely different from that of the umbrella, and the radio disc is a brand-new mechanism form.

Wherein, the mechanism of unfolding and folding the radio disc 120 is the core of the invention. The following describes in detail the operation of unfolding and folding the radio disc 120 of the recording apparatus 100 according to the embodiment of the invention with reference to fig. 1 to 8.

Specifically, the umbrella cover 129 of the radio disc 120 may be made of plastic cloth, so that the umbrella-shaped radio receiving surface 121 of the radio disc 120 has good fatigue resistance, and the radio receiving surface 121 cut into an umbrella shape may be fixed on the umbrella ribs 123 by glue (or in other manners). A plurality of umbrella ribs 123 arranged along the circumferential direction of the rotating shaft ring 122 at intervals can be retracted and extended under the dual action of the top block 131 and the elastic ring 124, so that the opening and closing of the umbrella-shaped sound receiving surface 121 can be driven. When the rotary handle 134 is rotated, the circular motion of the rotary handle 134 can be converted into the linear motion of the top block 131 under the action of the driving assembly. The top block 131 moves linearly in the casing 110 along the inner wall of the casing 110 in the axial direction (for example, BC direction in fig. 2) (the moving direction is determined by the rotating direction of the rotary handle 134). When top block 131 moves in the direction of C → B, for example, the top of top block 131 abuts the end of rib 123, applying pressure thereto, causing rib 123 to expand against the pull of elastic ring 124; when the top block 131 moves in the direction B → C, for example, the pressure of the top block 131 on the end of the rib 123 disappears and the pulling force of the elastic ring 124 starts to act to gather the rib 123. Thus, the operation of unfolding and folding the radio disc 120 of the recording apparatus 100 according to the embodiment of the present invention is completed.
