Along with e-dictionary has had word pronunciation or music playback function, the loudspeaker sound effect there has been higher requirement, use the large scale loud speaker for this reason, but, the e-dictionary of said structure is placed on the circuit board 60 owing to loud speaker 30, the size of loud speaker 30 is restricted, and large scale loud speaker 30 has been thickeied the thickness of whole e-dictionary because thickness is thicker relatively; And, the arrangement of keyboard 20 also is affected, can only increase panel or reduce button, this is with opposing with development trend such as small and exquisite, light.In addition, loud speaker 30 is to be fixed on the body 10, and dismounting inconvenience causes easily with circuit board 60 and electrically connects loose contact.
The utility model content
The purpose of this utility model is to provide a kind of speaker configurations structure of portable electric device, under the situation that keeps original portable electric device thickness and integrated multiple combination function, can use the large scale loud speaker, makes the sound effect of loud speaker better; And, making the convenient and assembling quality raising of electronic installation dismounting, the sound effect of loud speaker is better.
For achieving the above object, the purpose of this utility model is achieved in that the speaker configurations structure of portable electric device, comprises e-dictionary body, upper cover body, keyboard, display screen, circuit board, loud speaker, battery; Wherein, described body comprises panel, lower cover; Panel has for the through hole that button is set; Keyboard is arranged in body panels; Circuit board is arranged in the body; Upper cover body is connected with body pivot; Display screen is installed in upper cover body, electrically connects with circuit board; The loud speaker lid is arranged in the body; Loud speaker is arranged in the loud speaker lid, electrically connects with circuit board; Battery is arranged at body and upper cover body connecting portion; Described loud speaker is arranged at the circuit board below; Have through hole on described circuit board and the keyboard, this hole size is corresponding with described speaker bottom lug boss size; Described body lower cover is opened the hole, and described loud speaker and loud speaker lid stretch out this lower cover through hole, and described speaker bottom lug boss is stretched in the through hole on described circuit board and the keyboard.
Again, described loud speaker is fixed in the loud speaker lid, and described loud speaker lid is fixed in panel and maybe can be directly fixed on the circuit board.
As further improvement of the utility model, body lower cover described in the utility model is a potential difference structure, makes lower cover and places the plane or the holder held is held and formed an acoustic resonance space between facies palmaris and body, makes the acoustics of loud speaker better.
Described loud speaker lid by screw pass circuit board, keyboard is fixed in panel and maybe can be directly fixed on the circuit board.
Advantage of the present utility model is:
During the installation and design of the utility model loud speaker, utilize body to place the spatial altitude of battery, by loud speaker being fixed in the circuit board below, and the via area of circuit board and keyboard only needs the bottom protrusion portion size of loud speaker, perforate that need not whole loud speaker size, so just help electric wiring and component placement and key arrangement and carry out more complete arrangement, make the thicker horn designs of large scale can apply in the portable electric device; Simultaneously, loud speaker is fixed in the circuit board below, also is convenient to dismantle structures such as body; In addition, loud speaker is arranged at the lower cover through hole, cooperate lower cover to change incline structure into, make lower cover and placement plane form an acoustic resonance space, make the acoustics of loud speaker better, particularly e-dictionary has had word pronunciation or music playback function, and good loudspeaker sound effect has guaranteed the reduction of word pronunciation or music sound.
