The driving mechanism is respectively connected with the loudspeaker and the motor. When the motor rotates, the driving mechanism drives the loudspeaker to move linearly. The technical scheme provided by the structure of the slipping loudspeaker leads the loudspeaker of the display device to be capable of moving up and down along with the sound producing position of the display device, thereby effectively improving the sound effect of the display device and bringing better experience to the users.
Description
Technical field
The utility model belongs to the loudspeaker techniques field, relates in particular to the loud speaker of display device.
Background technology
Existing display device also provides the acoustic information that more and more enriches to the user when image information is provided, and the user is more and more higher to the requirement of the picture quality of display device, and is also more and more higher to the requirement of sound quality simultaneously.
With the television set is example, and the reproduction of TV signal sound generally realizes by the audio amplifier on the television set.Commonplace method is at present: a loud speaker respectively is installed on the left and right sides of TV shell, the position of these two loud speakers is fixed, reproduce the sound corresponding by the cooperation of left and right sides loud speaker, thereby realize the reproduced in synchronization of sound and image with image.In high-quality television equipment, use a common loud speaker often can not get a desired effect sometimes, therefore, can adopt a woofer and a high pitch loudspeaker simultaneously in the left and right sides.The television equipment that also has only disposes a woofer, and is placed on the below of TV shell, the configuration high pitch loudspeaker then about each one, to reach same effect.
The loud speaker of present most television sets is immovable, can not satisfy the demand of some special users.Though there has been the loud speaker of the television set of minority can be movable, for example in disclosed Chinese patent CN2842928Y on November 29th, 2006, it has described a kind of TV of rotatable external voice box, realize because its loud speaker mobile is the rotation by two end housings about TV, and can not realize that loud speaker moves according to the position straight line of source of sound.
As everyone knows, adopting the loud speaker of each side installation in TV shell, is the principle of utilizing sound imaging (sound imaging) system, obtains different sound effects, to reduce the real scene of audio frequency and video when recording better.By controlling the sounding of the loud speaker that is provided with about this, make the user sound sound seem from the middle of these two loud speakers certain a bit on.Therefore, present television set all generally adopts this method to come the design and installation loud speaker.
Under the smaller situation of television screen, the reduction coordination of carrying out sound and image in this way is proper, but along with TV panelized gradually, the size of television set also strengthens gradually, and constantly having more, the TV of large scale (even having above 100 cun) appears on the market.Under the bigger situation of television set size, utilize this system principle and two fixing loud speakers are installed are carried out sound-reducing, sound effect will be very coarse, can't carrying out accurately to the sound of diverse location in television image source (position of the shape of the mouth as one speaks correspondence of speaking such as the people), sound position reproduces, when the distance that moves up and down on television image when source of sound is big, the position of loud speaker can not be moved, and can't carry out the reduction of actual sound really and accurately.So will reduce the result of broadcast of panel TV product greatly.
