Abstract
The utility model provides a micro projector capable of synchronously recording voice. The micro projector comprises a sound pick-up device, a RK2816 chip, a memory, a power management circuit, a micro projector optical machine, a USB HOST controller IC, a USB interface, and an optical machine driving IC. The sound pick-up device, the memory, the power management circuit, the optical machine driving IC, and the USB HOST controller IC are connected with the RK2816 chip. The USB interface is connected with the USB HOST controller IC. The micro projector optical machine is connected with the optical machine driving IC. The micro projector with simple structure is capable of recording voice of a user by the sound pick-up device and saving recorded voice data in the memory. An external memory device is capable of saving a file in the memory through the USB interface and the USB HOST controller IC, and the RK2816 chip reads the file in the memory and projects file information through the micro projector optical machine.
Description
[technical field]
The utility model relates to micro projector, but particularly a kind of micro projector of synchronization.
[background technology]
At present, the trend of using along with various portable multimedia apparatus (such as digital camera, digital camera-recorder, portable media player, notebook computer, mobile phone etc.) increases day by day, and the chance that the user shares various image informations by projector is more and more frequent.Existing projector can only carry out single projection not with the voice recording function.
A kind of " Portable miniature projector " is provided in the prior art, see that publication number is: 201540442U, open day be: the Chinese patent of 2010-08-04, its characteristics are to comprise casing, optical projection image-forming block, main circuit board, button wiring board and fan cooled parts, wherein casing is made of cylindrical main casing and circular lid shell, and is provided with feet in the bottom of main casing; The optical projection image-forming block is installed in the main casing, and the camera lens which is provided with is placed through in the camera aperture that the main casing side has; The fan cooled parts are installed in and are arranged in the other main casing of optical projection image-forming block side; Main circuit board and button wiring board are fixedly mounted on respectively the left and right side of main casing, and the lid shell of being put in main casing two sides by lid covers in, and also are provided with a plurality of function buttons that are connected with this button wiring board on the lid shell corresponding to the button wiring board.The volume of this utility model complete machine is very small and exquisite, structure is very compact, extremely is beneficial to carry; The use that can be connected with various multimedia equipments easily can be satisfied user's various multimedia application needs effectively.But this micro projector function singleness can not be carried out sound-recording function.
[summary of the invention]
The technical problems to be solved in the utility model, but be to provide a kind of micro projector of synchronization, and it also can be recorded in projection.
But the utility model is achieved in that a kind of micro projector of synchronization, comprising: acoustic pickup, RK2816 chip, storer, electric power management circuit, minitype projection machine ray machine, USB HOST controller IC, USB interface and ray machine drive IC; Described acoustic pickup, storer, electric power management circuit, ray machine drive IC, USB HOST controller IC all are connected with described RK2816 chip; Described USB interface is connected with described USB HOST controller IC; Described minitype projection machine ray machine is connected with described ray machine drive IC.
Further, the model of described ray machine drive IC is HX7027.
Further, described USB HOST controller IC model is MAX3421E.
Further, described micro projector also comprises a control button, and this control button is connected with described RK2816 chip.
The utility model has the advantage of: the utility model is simple in structure, and it can be recorded user's voice by acoustic pickup, and the speech data of recording is stored in the storer; And External memory equipment can be stored in file in the storer by USB interface and USB HOST controller IC, and the RK2816 chip carries out Projection Display with fileinfo by the minitype projection machine ray machine by the file in the read memory.The utility model has reached the effect of one-object-many-purposes, and easy to operate.
[description of drawings]
Fig. 1 is the structural representation of the utility model the first embodiment.
Fig. 2 is the structural representation of the utility model the second embodiment.
[embodiment]
See also shown in Figure 1, but the micro projector of a kind of synchronization of the first embodiment of the present utility model comprises: acoustic pickup 1, RK2816 chip 2, storer 3, electric power management circuit 4, minitype projection machine ray machine 5, USB HOST controller IC, USB interface 6 and ray machine drive IC; Described acoustic pickup 1, storer 3, electric power management circuit 4, ray machine drive IC, USB HOST controller IC all are connected with described RK2816 chip 2; Described USB interface 6 is connected with described USB HOST controller IC; Described minitype projection machine ray machine 5 is connected with described ray machine drive IC.This ray machine drive IC can drive micro projection ray machine 5 and carry out projection; This USB HOST controller IC can be identified the external unit (not shown) that is inserted into USB interface 6, need not installation of drive software.
In the present embodiment, the model of described ray machine drive IC is HX7027; Described USB HOST controller IC model is MAX3421E.
See also shown in Figure 2ly, be the second embodiment of the present utility model.The difference of this second embodiment and the first embodiment is: described micro projector also comprises a control button 7, and this control button 7 is connected with described RK2816 chip 2.This control button 7 can be controlled the unlatching of micro projector recording, broadcast of closing, recording of recording etc.
In a word, the utility model is simple in structure, and it can be recorded user's voice by acoustic pickup, and the speech data of recording is stored in the storer; And External memory equipment can be stored in file in the storer by USB interface and USB HOST controller IC, and the RK2816 chip carries out Projection Display with fileinfo by the minitype projection machine ray machine by the file in the read memory.The utility model has reached the effect of one-object-many-purposes, and easy to operate.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
