Description

Portable multimedia device

The present invention relates to a multimedia device, and more particularly to a multifunctional micro-projection device.

Press, traditional projectors are mostly large and bulky, and can only be used indoors in conference rooms or audio-visual rooms. For this, the industry has developed smaller pocket projectors or pico projectors (Pico Projector). ), solves the problem of carrying the projector, however, the conventional pico projector has only a single projection function, and at the same time, due to its small battery capacity, the use time is limited and it faces the trouble of requiring frequent charging, and the conventional micro projection Generally, the machine can only be connected to the indoor power supply through the power cord for charging. It is inconvenient to use. Therefore, how to improve the above-mentioned defects is the technical difficulty that the applicant of the case wants to solve.

In view of the fact that the conventional pico projector has a single function and the battery can only be charged through the power cord, resulting in poor practicability and ease of use, the purpose of this creation is to develop a micro-projection device with multiple functions.

Another object of the present invention is to develop a miniature projection device that can improve the convenience of charging.

In order to achieve the above objectives, the present invention provides a portable multimedia device. The device body comprises: a device body, the device body is provided with a rechargeable battery, a controller, a micro projector, a power interface, a wireless transceiver module, a situation light source and a speaker, the micro projector, the wireless transceiver module The group, the situation light source and the speaker are respectively electrically connected to the controller, the rechargeable battery is electrically connected to the controller and the power interface respectively, and the device body is provided with a network camera, and the network camera is electrically connected with the controller. .

With the above structure, the creation can simultaneously combine various functions such as a projector, a Bluetooth speaker, and a network camera, and at the same time, the situational atmosphere of the scene environment can be created through the situational light source, thereby greatly improving the entertainment effect, thereby enabling the creation to reach a large Improve the effectiveness of the product.

As shown in the first figure, the present invention provides a portable multimedia device, which includes: a device body 3, which is specifically a casing, which can have various appearances, and the present invention does not The device body 3 is provided with a rechargeable battery 31, a controller 32, a micro projector 33, a power interface 34, a wireless transceiver module 35, a situation light source 36, and a speaker 37. The micro projector 33, the wireless transceiver module 35, the ambient light source 36 and the speaker 37 are electrically connected to the controller 32, respectively, the rechargeable battery 31 is electrically connected to the controller 32 and the power interface 34, and the power interface 34 can be USB ( Universal Serial Bus, Universal Serial Bus) An interface (such as a Micro USB interface) or an AC power (AC) interface, thereby enabling the creation of the rechargeable battery 31 via an external power line such as a USB signal line or an AC power line (sometimes, the power line) A transformer having a rectifying function is also included, but the detailed structure of the power cord is a well-known technique in the art, and therefore will not be described in detail herein, in order to extend the power and device operation time, and in addition, the wireless transceiver module The group 35 may specifically be a Bluetooth module, a WiFi module, a mobile internet module (such as a 3G, 4G mobile internet module) or a combination thereof, and the context light source 36 is configured to receive a control command from the controller 32. And generating a situation light corresponding to the control command, wherein the ambient light may include a change or combination of light in an action state such as color, brightness, or flicker, and the ambient light source 36 may specifically be an LED or a photoelectric IC; The present invention may further include a network camera 4, which is disposed on the device body 3 and electrically connected to the controller 32, thereby enabling remote home care and video conferencing. Security monitoring and other functions, so that this creation can simultaneously have a variety of functions such as projection and network photography; please refer to the first and second figures, with the device body 3 is provided with a wireless transceiver module 35 and The built-in speaker 37 allows the user to wirelessly connect the creation to a mobile device such as a mobile phone or tablet (specifically, via Bluetooth pairing and/or WiFi connection). The controller 32 can receive the video signal transmitted by the mobile device 7, and then transmit the video signal to the micro projector 33 or the speaker 37, respectively, so that the micro projector 33 can project the image on the projection screen 8. The speaker 37 can play the sound effect or music, so the creation can also have the function of the Bluetooth wireless speaker. In addition, the controller 32 can also be controlled according to the APP (application) on the mobile device 7 or cooperate with the audio and video. The signal generates a corresponding control command, so that the situation light source 36 emits various different situational lights, which can create or bring the atmosphere and situation of the scene, thus, When this work is applied to KTV singing and other activities for camping out, it will achieve the best audio-visual entertainment effect, which can greatly enhance the practicality of this creation.

In addition, as shown in the first figure, the present invention may further include an NFC tag (Near Field Communication Tag) 5, which is disposed on the device body 3 and electrically connected to the controller 32.
