Description
Technical field
This utility model relates to a kind of brain wave amplifier.
Background technology
Along with the application of computer in biology, the people's higher brain function research carried out based on event related potential (Event-relatedpotentials, ERP) technology becomes current research means.Due to BEP very faint (wave amplitude is 0 ~ 30 μ V), and be usually submerged in background noise, so in brain wave ERP studies, usually need to use brain wave amplification system.
Utility model content
This utility model provides the brain wave amplifier that a kind of structure is simple, portable, be easy to die sinking processing.
The technical solution of the utility model is to provide a kind of brain wave amplifier, and it comprises the shell of rectangular structure, it is characterized in that,
Be provided with magnification circuit plate in described shell, described magnification circuit plate stretches out outside described shell by thunder interface of writing from memory, and also comprises the battery of powering to described magnification circuit plate in described shell.
Preferably, described shell comprises fore shell, center and back cover, and described center is square shape structure, described center is provided with the charging inlet and switch that connect described magnification circuit plate.
Preferably, four angles of described back cover respectively arrange a joint pin, described fore shell, center and back cover link together by the screw be threaded on described joint pin through described fore shell.
Preferably, described back cover arranged outside one battery case, described battery is arranged in described battery case, and described battery case is closed by a battery cover.
Preferably, crisscrossly on described battery cover several reinforcements are provided with.
Preferably, described back cover is also provided with several draw-in grooves, described magnification circuit plate inlay card is on described draw-in groove.
Brain wave amplifier volume of the present utility model is little, good looking appearance, portable, shell adopts three stage structure, is convenient to injection mould.In addition, by draw-in groove inlay card circuit board, make overall structure simple, be convenient to assembling.

Fig. 2 is the decomposition texture schematic diagram of this utility model brain wave amplifier.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of brain wave amplifier of the present utility model comprises the shell of rectangular structure, be provided with magnification circuit plate 10 in shell, magnification circuit plate 10 stretches out outside shell by thunder interface 12 of writing from memory, and also comprises the battery 14 of powering to magnification circuit plate 10 in shell.
Shell comprises fore shell 16, center 18 and back cover 20, and center 18 is square shape structure, center 18 is provided with the charging inlet 22 and switch 24 that connect magnification circuit plate 10.
Four angles of back cover 20 are respectively arranged a joint pin 26, four to be threaded in respectively on a joint pin 26 through the screw (not shown) of fore shell 16, thus fore shell 16, center 18 and back cover 20 are linked together.
Back cover 20 arranged outside one battery case 28, battery 14 is arranged in battery case 28, and battery case 28 is closed by a battery cover 30.Crisscrossly on battery cover 30 be provided with several reinforcements 32.
Further, back cover 20 is also provided with several draw-in grooves (not shown), magnification circuit plate 10 inlay card is on draw-in groove.
Above embodiment is only this utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
