Abstract
The utility model discloses a learning assister, comprising upper and lower tubes with tube frames disposed outside, wherein the upper part of the tube frame is disposed with a connector. A sound collector connected with the lower tube contains a sound separator, while the lower part of the sound collector is disposed with an electric sound device communicated with the sound separator. The upper tube is inserted into the lower tube with a brake between them. The connector is disposed with at least one through hole. The tube frame can effectively protect the upper and lower tubes and the frame to improve the service life of invention. With the sound separator, when external voice signal and user voice signal enter into the sound collector at same time, said two voice signals can be effectively separated, to avoid interference, improve the voice effect and avoid sound loss.
Description
Technical field
The utility model relates to a kind of study article, relates to a kind of learning-aid device specifically.
Background technology
China Patent No. 03244880.5 discloses a kind of Memory assistant device, comprises upper conduit, downcomer, sound collector, clamping device.But the combination of upper conduit, downcomer, clamping device is insecure, damages easily in daily use.The sound that user's sound and electroacoustic device is inserted in sound collector is not separated, and causes in use that user's oneself sound and the voice signal that electroacoustic device inserts interfere with each other, and influence is use normally.When the user used, sound can outwards be revealed by sound collector, caused sound to run off, and had influenced the sharpness of sound.
The utility model content
The technical matters that the utility model solved provides a kind of learning-aid device, has solved the loss that interferes with each other and enter sound collector sound between the sound of user oneself in the insecure or use of the combination of upper conduit, downcomer, clamping device and the voice signal that electroacoustic device inserts.
The technical solution of the utility model is as follows:
A kind of learning-aid device comprises upper conduit, downcomer, and described upper conduit and downcomer outer setting have the conduit shell, is provided with the web member that is connected with described upper conduit on the top of described conduit shell.
Preferably, the sound collector inside that is connected with described downcomer is provided with the sound tripping device.
Preferably, the bottom of described sound collector is provided with electroacoustic device, and described electroacoustic device communicates with described sound tripping device.
Preferably, described upper conduit inserts in the downcomer, and is provided with clamping device between upper conduit and downcomer.
Preferably, described web member is provided with at least one through hole.
The conduit shell can effectively be protected upper conduit, downcomer and clamping device, has prolonged the serviceable life of learning-aid device.Owing to be provided with the sound tripping device, when the voice signal of foreign medium and user's oneself voice signal enters sound collector simultaneously, can effectively these two kinds of voice signals be separated, avoided the phase mutual interference, improved the sharpness of voice.When the user wears the utility model and reads aloud, owing to be provided with the sound tripping device, can avoid sound to run off from the slit between sound collector and the electroacoustic device, in like manner, when the utility model was connected with foreign medium by electroacoustic device, the sound that enters sound collector entered downcomer by the sound tripping device, entered user's ear then by upper conduit, web member, thereby avoided sound to be lost, improved the sharpness of sound by the upper opening of sound collector.
Description of drawings
Fig. 1 is the structural representation of learning-aid device preferred embodiment;
Fig. 2 is the side view of learning-aid device preferred embodiment;
Fig. 3 be in the learning-aid device sound collector prolong A-A to sectional view;
Fig. 4 is the enlarged drawing of sound tripping device in the learning-aid device.
Embodiment
With reference to the accompanying drawings preferred embodiment of the present utility model is described in detail.
Referring to figs. 1 through shown in Figure 4, in the preferred embodiment of the present utility model, learning-aid device comprises upper conduit 2, downcomer 1, sound collector 3, is provided with clamping device between upper conduit 2, downcomer 1.Be provided with electroacoustic device 5 in the bottom of sound collector 3, this electroacoustic device 5 is connected with the internal cavities of sound collector 3, is used for the voice signal of foreign medium is input to learning-aid device.The said external medium can be media play instruments such as radio, sound-track engraving apparatus, televisor.In order to protect upper conduit 2, downcomer 1 and clamping device better; outer setting at said structure has conduit shell 6; be provided with web member 7 on the top of this conduit shell 6; this web member 7 communicates with upper conduit 2; and this web member 7 is provided with through hole, is used for the ear of sound conduction to the people.
When sound that imports into when electroacoustic device 5 and user's sound entered sound collector 3 simultaneously, the internal cavities of above-mentioned two shared these sound collectors 3 of voice signal must cause interfering with each other of above-mentioned two voice signals.In order to eliminate this interference, effectively above-mentioned two kinds of voice signals are separated, be provided with sound tripping device 4 in the inside of sound collector 3, this sound tripping device 4 is divided into two parts up and down with the internal cavities of sound collector 3, and upper cavity is used for importing user's sound into sound collector 3.The bottom of sound tripping device 4 is connected with electroacoustic device 5, is used for importing the voice signal of foreign medium into sound collector 3.
When the user uses learning-aid device, can drive the relative height that upper conduit 2 is adjusted web member 7 by pulling conduit shell 6, then web member 7 is put into user ear.User's voice signal enters by the opening on sound collector 3 tops, after amplifying through the sympathetic response of sound collector 3 then, imports user's ear into by downcomer 1, upper conduit 2, web member 7.The voice signal of foreign medium enters into sound collector 3 by electroacoustic device 5, sound tripping device 4, after amplifying through the sympathetic response of sound collector 3, imports user's ear into by downcomer 1, upper conduit 2, web member 7.Owing to be provided with sound tripping device 4, when the voice signal of foreign medium and user's oneself voice signal enters sound collector 3 simultaneously, can effectively these two kinds of voice signals be separated, avoided the phase mutual interference, improved the sharpness of voice.
When electroacoustic device 5 was not connected with foreign medium, the user can directly read aloud, and listened to the sound of reading aloud by web member 7, owing to be provided with sound tripping device 4, can avoid sound to run off from the slit between sound collector 3 and the electroacoustic device 5.When electroacoustic device 5 is connected with foreign medium, both can listen continuously and read, perhaps only listen and do not read, make the sound that enters sound collector 3 enter downcomer 1 by this sound tripping device 4 by sound tripping device 4, enter user's ear by upper conduit 2, web member 7 then, thereby avoided sound to be lost, improved the sharpness of sound by the upper opening of sound collector 3.
