DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] Please refer to FIG. 1, which is a systematic diagram of an image-shooting and sound-receiving device according to an embodiment of the present invention. As shown in FIG. 1, the multifunctional image-shooting and sound-receiving device 1 of the present invention includes a controller 10, a built-in microphone 13, a switching unit 11, an adjustment unit 12, a drive unit 17, a sensor 16, a lens 15, and a motor 14. The built-in microphone 13 is connected to the controller 10 and can receive at least one microphone sound signal. The switching unit 11 is connected to the controller 10 and transmits a switching signal to the controller 10. The adjustment unit 12 is connected to the controller 10 and transmits an adjustment signal to the controller 10. The drive unit 17 is connected to the controller 10 and receives a drive control signal from the controller 10. The sensor 16 is connected to the controller 10, receives a sensing control signal from the controller 10, and transmits sensing information to the controller 10. The motor 14 is connected to the drive unit 17, receives a driving signal from the drive unit 17, and is integrated with the lens 15. The controller 10 switches the multifunctional image-shooting and sound-receiving device 1 to one of a first mode and a second mode according to the switching signal transmitted by the switching unit 11. In this embodiment, the first mode is a manual mode, and the second mode is an automatic mode.

[0022] Please refer to FIGS. 3A to 3C, which are a front view, a top view, and a side view of the multifunctional image-shooting and sound-receiving device 1, respectively. A connection port 18 of the multifunctional image-shooting and sound-receiving device 1 is connected through a USB-C cable 33 to a computing device. When the switching signal switches the multifunctional image-shooting and sound-receiving device 1 to the manual mode, the controller 10 receives the adjustment signal and generates the drive control signal according to the adjustment signal, and the drive unit 17 generates the driving signal according to the drive control signal. That is, when the user generates the switching signal through the switching unit 11 (that is, a switching button 31) to switch the multifunctional image-shooting and sound-receiving device 1 to the manual mode, the user can operate the adjustment unit 12 (i.e., a rotary knob 30) to generate the adjustment signal, so that the controller 10 receives the adjustment signal and generates the drive control signal according to the adjustment signal, the drive unit 17 generates the driving signal according to the drive control signal, the driving signal and the sensing control signal drives the motor 14 to change the focal length of the lens 15 (the user can use a slide cover 32 to open/close the lens 15).

[0023] In contrast, when the switching signal switches the multifunctional image-shooting and sound-receiving device 1 to the automatic mode, the controller 10 computes and generates the drive control signal according to the sensing information transmitted by the sensor 16, and the drive unit 17 generates the driving signal according to the drive control signal. That is, when the user generates the switching signal through the switching unit 11 (i.e., the switching button 31) and switches the multifunctional image-shooting and sound-receiving device 1 to the automatic mode, the controller 10 automatically generates the drive control signal (at this time, the adjustment signal generated by the user through the rotary knob 30 will not be converted into a drive control signal), the drive unit 17 generates the driving signal according to the drive control signal, and the driving signal and the sensing control signal will drive the motor 14 to change the focal length of the lens 15.

[0024] According to the embodiment of the present invention, the controller 10 may include or be implemented as a high-performance vision processor, such as Rockchip Electronics Co., Ltd.'s product RV1126, or SigmaStar Technology Corp.'s product SAC8539.

[0025] According to the embodiment of the present invention, the drive unit 17 may include or be implemented as a micro-actuator driver IC, such as Fitipower Integrated Technology Inc.'s product FP5502.

[0026] Please refer to FIG. 2, which is a systematic diagram of an image-shooting and sound-receiving device 1′ according to another embodiment of the present invention. As shown in FIG. 2, compared with the multifunctional image-shooting and sound-receiving device 1 of FIG. 1, the multifunctional image-shooting and sound-receiving device 1′ further includes a charging unit 20, a wireless microphone module 21, a wireless module 19, and a button assembly 22. The charging unit 20 is connected to the controller 10 and transmits a connection charging signal. The wireless microphone module 21 is connected to the charging unit 20 for charging, and can be detached from the charging unit 20. The wireless module 19 is connected to the controller 10 and receives a wireless control signal from the controller 10. The wireless microphone module 21 includes a microphone, a wireless communication controller, and a battery, wherein the wireless communication controller is paired with the wireless module 19 for communication. The button assembly 22 is connected to the wireless microphone module 21, and the button assembly 22 may include a power switch, a mute switch, and other switching switches (such as a switch for remote controlling the switching unit 11).

[0027] Please refer to FIGS. 4A to 4D, which are respectively a front view, a top view, a side view, and a perspective view viewed from a rear side of the multifunctional image-shooting and sound-receiving device 1′. The connection port 18 of the multifunctional image-shooting and sound-receiving device 1′ is connected through a USB-C cable 42 to a computing device. When the user generates the switching signal through the switching unit 11 (that is, a switching button 31′) to switch the multifunctional image-shooting and sound-receiving device 1′ to the manual mode, the user can operate the adjustment unit 12 (i.e., a rotary knob 30′) to generate the adjustment signal, so that the controller 10 receives the adjustment signal and generates the drive control signal according to the adjustment signal, the drive unit 17 generates the driving signal according to the drive control signal, and the driving signal drives the motor 14 to change the focal length of the lens 15 (the user can open/close the lens 15 by sliding the lens 15).

[0028] In contrast, when the user generates the switching signal through the switching unit 11 (i.e., the switching button 31′) to switch the multifunctional image-shooting and sound-receiving device 1′ to the automatic mode, the controller 10 automatically computes and generates the drive control signal according to the sensing information transmitted by the sensor 16 (at this time, the adjustment signal generated by the user through the rotary knob 30′ will not be converted into a drive control signal), and the drive unit 17 generates the driving signal according to the drive control signal, and the driving signal and the sensing control signal will drive the motor 14 to change the focal length of the lens 15.

[0029] In addition, as shown in FIGS. 4E and 4F, when the wireless microphone module 21 is detached from the charging unit 20, the wireless module 19 receives the wireless control signal to communicate with the wireless microphone module 21, and thus the wireless module 19 receives sound. In contrast, when the wireless microphone module 21 is connected to the charging unit 20, the charging unit 20 transmits a connection charging signal to the controller 10 to disable the sound-receiving of the wireless microphone module 21 and enable the sound-receiving of the built-in microphone 13. At this time, both the multifunctional image-shooting and sound-receiving device 1′ and the multifunctional image-shooting and sound-receiving device 1 can only receive sound through the built-in microphone 13.

[0030] According to the embodiment of the present invention, the wireless module 19 may include or be implemented as, for example, Telink Semiconductor Co. Ltd.'s product TLSR951x.

[0031] According to the embodiment of the present invention, the charging unit 20 may include or be implemented as a battery charger IC, such as Fitipower Integrated Technology Inc.'s product FP6908.

[0032] In summary, the multifunctional image-shooting and sound-receiving device of the present invention can perform image-shooting in different ambient environments or image-shooting objects by switching the manual/automatic focus adjustment mode, and clearly receive sound in different ambient environments, and relative positions and distances between the microphone and the sound source by the detachable wireless microphone module.

[0033] The present invention is not limited to the above-described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the present invention.

[0034] Accordingly, these modifications and variations made to this invention fall within the scope of the appended claims and the equivalents.
