Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure. In addition, all the embodiments or implementations of the present application can be arbitrarily combined to form new embodiments adaptively.

This application is often in many noise environment to recording of video, to being difficult to control of environment radio reception, the sound end is made an uproar great, and final radio reception effect is not good, the problem that whole video quality is also lower. Referring to fig. 1, an embodiment of the present application provides a video capturing apparatus 1000 capable of improving a radio reception effect of an electronic device and improving overall video quality. The video camera 1000 includes an electronic device 200 and a video camera assistant 100. The video shooting assisting apparatus 100 is sleeved on the periphery of the electronic device 200. The electronic device 200 includes, but is not limited to, a mobile phone, a notebook computer, a tablet computer, a camera, a wearable device, and any other electronic product with a camera.

The video shooting assistance device 100 is mounted on the electronic device 200, can be used as an accessory of the electronic device 200, and can perform targeted and directional sound collection on an operator when the electronic device 200 shoots, and can efficiently collect sound in any direction, namely, in all directions of the operator, without being limited to the direction in which the operator is positioned.

For the sake of conveniently illustrating the structure of the video shooting assistance apparatus 100, the electronic device 200 is taken as a mobile phone in the present application as an example for description. Referring to fig. 2, the electronic device 200 may include a camera module including a front camera 202 and a rear camera 203. Wherein, the lens orientation of the front camera 202 is the same as the orientation of the display screen 204 of the electronic device 200. The front camera 202 may be disposed in a display area or a non-display area of the display screen. The rear camera 203 is oriented opposite to the front camera 202. Due to the limitation of the setting space, the rear camera 203 has more functions than the front camera 202, for example, the rear camera 203 can have a wider wide angle, the image quality is clearer, zooming can be realized, and the like. Thus, using the rear camera 203 as a shooting video is an available option for obtaining a better shooting effect, but the rear camera 203 is not convenient for shooting the operator himself, and not only can a better all-round sound reception effect be realized by setting the video shooting assistance apparatus 100, but also self-shooting through the rear camera 203 can be realized. Of course, in other embodiments, the camera module may only include the rear camera 203, and by providing the video shooting assistance device 100, a higher quality self-shooting can be achieved through the rear camera 203, and the front camera 202 can be eliminated.

Referring to fig. 3, the electroacoustic assembly 3 is disposed on the rotating structure 2 to rotate with the rotating structure 2 relative to the side frame 12. The electro-acoustic assembly 3 includes, but is not limited to, a microphone. The microphone is an energy conversion device that converts a sound signal into an electric signal. The types of microphones in this application include, but are not limited to, moving coil, condenser, electret, and silicon micro-microphones, among others, liquid microphones and laser microphones. In this embodiment, the electroacoustic component 3 may be a gun-type microphone, a wireless audio receiver, or a wireless microphone.

Optionally, referring to fig. 6, the rotation axis of the rotating structure 2 intersects or is perpendicular to the outer surface 125 of the first frame 121. Further, the rotation axis of the rotating structure 2 can be along the X-axis direction, and during the rotation of the rotating structure 2, the rotating structure 2 can drive the electroacoustic component 3 to face the side of the back shell 11 of the housing 1 or face the back side of the back shell 11 of the housing 1. Optionally, the rotation structure 2 may drive the electroacoustic component 3 to rotate at least one revolution, so that the electroacoustic component 3 can receive sound for an operator in each direction around the X-axis direction. In other words, no matter the operator uses the front camera 202 or the rear camera 203 of the electronic device 200, the electroacoustic component 3 can be rotated to the sound emitting portion facing the operator (the sound emitted by the operator is the main audio to be collected by the electroacoustic component 3), so as to realize directional sound collection in any direction, improve the receiving effect of the main audio of the operator, reduce the interference of the environmental noise, and improve the collected audio effect.

It is understood that the rotation mode of the rotating structure 2 may be a manual driving rotation or an electric rotation, and the application is not limited in this respect.

It can be understood that the audio signal collected by the microphone of the auxiliary video camera device 100 can be transmitted to the electronic device 200 through wired or wireless transmission between the auxiliary video camera device 100 and the electronic device 200, so as to be combined with the image signal collected by the camera module of the electronic device 200 to form an audio-video signal.

The application provides a video shooting auxiliary device 100, this video shooting auxiliary device 100 installs in electronic equipment 200, through setting up rotatable electroacoustic component 3, when electronic equipment 200 gathered audio frequency and video, can rotate electroacoustic component 3 to just to the operator, in order to realize electroacoustic component 3 and all can carry out the radio reception of directive property to the operator in arbitrary position, improve the receiving effect of operator's main audio frequency, reduce the interference of environmental noise, improve electronic equipment 200's radio reception effect, improve whole video quality.

The specific structure of the electroacoustic component 3, the specific structure of the rotating structure 2, and the electrical connection manner of the electroacoustic component 3 provided in the present application are illustrated below with reference to the drawings.

Referring to fig. 6, the electroacoustic assembly 3 includes an electroacoustic portion 31 and a supporting portion 32.

Referring to fig. 6, one end of the supporting portion 32 is connected to the side frame 12. In this embodiment, one end of the supporting portion 32 may be connected to the outer surface 125 of the first frame 121. The support portion 32 may extend at least partially in the X-axis direction.

Referring to fig. 6, one end of the electroacoustic portion 31 is connected to one end of the supporting portion 32 away from the side frame 12. The electroacoustic part 31 may be a microphone module. The extending direction of the electroacoustic part 31 intersects or is perpendicular to the normal direction of the portion of the attached side frame 12. The electroacoustic part 31 may extend in a direction perpendicular to the X-axis direction, in other words, the electroacoustic part 31 may be parallel or substantially parallel to the outer surface 125 of the first bezel 121.

Further, when the electroacoustic part 31 is rotated to the side of the back case 11, the electroacoustic part 31 is projected with respect to the back case 11. When the operator faces the back case 11, the electroacoustic component 31 is closer to the operator relative to the back case 11, so as to collect more main audio of the operator, reduce the collection of environmental noise, and improve the audio collection effect of the audio and video of the electronic device 200. Accordingly, when the operator faces toward the display screen 204 of the electronic apparatus 200, the electroacoustic part 31 is closer to the operator with respect to the display screen 204 of the electronic apparatus 200 to collect more of the main audio of the operator.

In one possible embodiment, referring to fig. 6, the supporting portion 32 includes a first supporting portion 321 and a second supporting portion 322 intersecting each other. The first support portion 321 connects the side frame 12 (the outer surface 125 of the first bezel 121) and extends in a direction (X-axis direction) gradually away from the side frame 12. The extending direction of the second support 322 is the same as the extending direction of the electroacoustic part 31. The second supporting portion 322 and the electroacoustic portion 31 both extend in a direction perpendicular to the X-axis. The second support 322 may bring the electroacoustic part 31 closer to the operator.

Further, the second support 322 is retractable. The extending and contracting direction of the second supporting portion 322 is the same as the extending direction of the second supporting portion 322. The second supporting portion 322 extends in a direction perpendicular to the X axis, and the second supporting portion 322 extends and contracts in the direction perpendicular to the X axis. As the second supporting portion 322 is elongated along the X-axis direction, the distance between the electroacoustic portion 31 and the first supporting portion 321 is increased, and when the electroacoustic portion 31 faces the operator, the electroacoustic portion 31 is further close to the operator, so that the intensity of the main audio collected by the operator is higher, the noise intensity is relatively low, and the effect of collecting audio and video by the electronic device 200 is improved. It will be appreciated that the primary audio may also be background audio in the environment collected by the operator.

In one embodiment, referring to fig. 7, the second supporting portion 322 may include a plurality of hollow posts sequentially sleeved on the first supporting portion. For example, the second support 322 includes a first hollow column 323, a second hollow column 324, and a third hollow column 325. One end of the first hollow column 323 is fixedly connected to the first support 321, one end of the second hollow column 324 is slidably connected to the outer circumferential surface of the first hollow column 323 and can abut against the other ends of the first support 321 and the first hollow column 323, and one end of the third hollow column 325 is slidably connected to the outer circumferential surface of the second hollow column 324 and can abut against the other ends of the first support 321 and the second hollow column 324. When the second hollow column 324 and the third hollow column 325 both abut against the first supporting portion 321, the second supporting portion 322 is in a contracted state. When the second hollow column 324 abuts the other end of the first hollow column 323 and the third hollow column 325 abuts the other end of the second hollow column 324, the second support 322 is in a maximum tension state.

The number of hollow columns is not limited in the present application, and in other embodiments, the number of hollow columns may be two. The second supporting portion 322 includes a first hollow column 323 and a second hollow column 324 sequentially sleeved thereon. One end of the first hollow column 323 is connected to the first support part 321. One end of the second hollow column 324 is slidably connected to the outer circumferential surface of the first hollow column 323. The other end of the second hollow column 324 is connected to the electroacoustic part 31. When one end of the second hollow cylinder 324 abuts the first support portion 321, the second support portion 322 is in a shortened state. When one end of the second hollow column 324 abuts the other end of the first hollow column 323, the second support 322 is in an extended state.

In another embodiment, referring to fig. 8, the second supporting portion 322 includes a plurality of rigid portions 326 and a rotating portion 327 rotatably connected between two adjacent rigid portions 326. The multi-segment rigid portions 326 are hingedly connected to one another. When the multi-stage rigid portion 326 is in the folded state, the second support portion 322 is in a shortened state in which the electroacoustic portion 31 is relatively distant from the sounding portion of the operator. When the multi-stage rigid part 326 is in the expanded state, the second support 322 is in the extended state, and the electroacoustic part 31 can approach the sounding part of the operator.

The second clamping portion 16 can be connected to the electrical connection portion (i.e., the conductive terminal 14). In other words, the electroacoustic part 31, the first conductive terminal 151, the second conductive terminal 161, the electrical connection part (i.e., the conductive terminal 14), the conductive port 205, and the power source of the electronic device 200 form a power supply path of the electroacoustic part 31 in sequence.

Optionally, the video shooting assistance apparatus 100 further includes an auxiliary power supply (not shown). The second clamping portion 16 can be connected with an auxiliary power supply. In other words, the electroacoustic part 31, the first conductive terminal 151, the second conductive terminal 161, and the auxiliary power supply sequentially form a power supply path of the electroacoustic part 31.

Further, referring to fig. 9, the rotating structure 2 is rotatably connected to the first engaging portion 15. The rotating structure 2 and the supporting portion 32 are connected between the first engaging portion 15 and the electroacoustic portion 31. The rotating structure 2 may be a rotating ring. The first clamping portion 15 is provided with an annular structure matched with the rotating ring. The rotating structure 2 is rotatable relative to the first snap-in portion 15. The support portion 32 is disposed on the rotating structure 2, and the electroacoustic portion 31 is connected to an end of the support portion 32 away from the rotating structure 2. When the rotating structure 2 rotates relative to the first catching portion 15, the electroacoustic portion 31 also rotates relative to the first catching portion 15.

Referring to fig. 9, the rotating structure 2 and the supporting portion 32 form a channel 328. The rotating structure 2 may be a hollow structure, and the supporting portion 32 may be a hollow structure. The hollow cavity of the rotating structure 2 and the hollow cavity of the supporting portion 32 form a channel 328, and the channel 328 communicates the first clamping portion 15 and the electroacoustic portion 31. Video capture assist device 100 also includes conductive line 329. The conductive wire 329 connects the electroacoustic part 31 to the first conductive terminal 151 of the first clamping part 15 via a channel, so that the electroacoustic part 31 and the first conductive terminal 151 can be electrically connected. The first conductive terminal 151 is electrically connected to the power supply of the electronic device 200 through the second conductive terminal 161, the conductive terminal 14 and the conductive port 205, so that the electroacoustic part 31 is electrically connected to the power supply of the electronic device 200.

The mounting hole 152 is fitted to the rotary member 21. One end of the rotating member 21 extends into the mounting hole 152 and is engaged with the first engaging portion 15, so that the rotating member 21 can rotate relative to the first engaging portion 15 under the action of external force.

Referring to fig. 10, the damping member 22 is connected to the first engaging portion 15. Alternatively, the damper 22 may be provided in the inner cavity of the first clamping portion 15. Alternatively, the damping member 22 includes, but is not limited to, an elastic rubber column or the like. The damper 22 may be fixed to a wall surface of the inner cavity of the first clamping portion 15. The damper 22 elastically abuts against the rotation peripheral surface of the rotary member 21. Namely, the damper 22 elastically abuts against a part of the outer peripheral surface of the rotary member 21. The rotating member 21 is rotated relative to the first engaging portion 15 while overcoming the friction force with the damping member 22. In other words, the damper 22 serves to damp the rotation of the rotary member 21 to prevent the electro-acoustic assembly 3 from loosening. Still alternatively, the damping member 22 may be rotatably coupled to a wall surface of the inner cavity of the first catching portion 15. When the rotary member 21 rotates, the rotary member 21 rotates the damping member 22 by friction transmission.
