Problems solved by technology

[0004] 2. Although some small products such as electronic dictionaries and language repeaters have dual functions of viewing and listening, they still cannot be used at night or under weak light conditions.
Moreover, the user needs to operate continuously and learn in a handheld manner.
Apart from distracting the user's attention, these actions have no substantial help for learning itself

Embodiment 1

[0030] Example 1. A language learning machine with a projection function such as Figure 1 ~ Figure 2 shown. It includes the case and the electronic circuits installed in the case. The electronic circuit includes a control unit 1 , a memory 2 connected to the control unit 1 , a key array 3 , a panel display 4 , a sound system 5 , an I / O interface 6 and a power supply 7 . The control unit 1 is also connected to a projection display device 11 .

[0031] The projection display device 11 includes an electroluminescent device light source 8 connected to the control unit 1, a projection display 9 installed in front of the electroluminescent device 8 and controlled and connected by the control unit 1, and a lens and optical assembly 10.13 installed in front of the projection display 9 as a projection carrier. refer to Figure 4 , the projection display device 11 is installed in the casing 12, and the casing 12 is installed in the cabinet. The control unit is a single-chip micro...

Embodiment 2

[0033] Example 2. A language learning machine with a projection function such as Figure 3 ~ Figure 4 shown. It is an English word projection learning device which downloads the spelling and pronunciation of English words from a PC. The control unit 1 of the device adopts a slice of MCU, which can directly decode and drive liquid crystal displays (front panel liquid crystal display 4 and projection liquid crystal display 5) to display required content. The projection light source 8 is a light emitting diode, and the output pin P2.1 can directly drive the projection light emitting diode to emit light. Through the address and data bus, the read and write operations of the digital information in the flash memory 2 are realized. Use 3 I / O ports to realize I / O connection between MCU 1 and PDIUSBD11USB interface chip 2 C communication, the other end of the chip is connected to the PC, which realizes the function of data transmission between the machine and the PC. It has an AUD...

Embodiment 3

[0037] Example 3. A language learning machine with a projection function such as Figure 5 shown. It is an English word learning machine that can download learning content by infrared.

[0038] Such as Figure 5 shown. The figure is omitted in the system with image 3 Similar to the circuit diagram of the same part, the system has two sets of optical projection systems, which can project different information onto different walls and roofs at the same time. One of the channels can be dedicated to memorizing words, turned on when in use, and turned off when not in use, and the other can be used to project other content. In addition to English learning, this machine is also a very practical projection table, which keeps the image of time on the selected wall all year round.

[0039] In addition, the machine uses infrared communication to communicate with the host computer or other peripherals, download / exchange information.

[0040] When the machine is used as the host to...

Abstract

The language learning machine with projection function includes casing and electronic circuit. The electronic circuit includes control unit, the connected memory, button array, panel display, sounder, I / O interface and power source. The control unit is also connected with one or several projecting display devices, and each of the projecting display devices includes electric light emitting device connected to the control unit, projecting display unit and lens combination. The present invention has not only displaying and sounding functions, but also the capacity of being used in learning in night and in poor lighting environment. The learned content may be displayed on display and other flat place, while sounding synchronously. The present invention may be used widely in language learning.

Description

technical field [0001] The invention belongs to the technical field of language learning machines, and more specifically relates to the design of a language learning machine with projection function and stronger auxiliary memory performance. Background technique [0002] Various memory aids have been used in the past for language learning. Traditional printed materials such as books, dictionaries, and various learning materials are vast and can be read at any time; most of the electronic tools such as computer dictionaries, online dictionaries, and electronic dictionaries that appear after the application of electronic technology have display and sound functions, which are convenient for query; Voice recorder, MD, MP3, CD, language repeater and other pronunciation standards, beautiful sound quality; too numerous to mention. However, the various auxiliary tools mentioned above have some disadvantages as follows: [0003] 1. For printed materials, le...
