[0002] Typical projectors can only provide mono speaker output, so the sound can only be played in mono
In addition, because the projector only has a mono design, if you want to further improve the sound quality to stereo or surround sound, it will be limited by the hardware architecture and cannot be achieved.

Embodiment Construction
[0031] The invention provides a projector for projecting an image to a projection screen, and adjusting the sound effect settings of the left and right channels according to the placement of the projector. In an embodiment of the present invention, the projector can also determine the sound field direction of the multi-channel sound effect according to the placement mode and the distance from the projection screen.
[0032] Figure 1(a) to Figure 1(f) It is used to illustrate possible situations between the projector 10, the user 12, and the projection screen 11. As shown in the figure, the projection screen 11 has a viewing surface 14 and a back surface 13. The viewing surface 14 is the side of the projection screen 11 facing the user 12, and the other side opposite to the viewing surface 14 is the back surface 13. The projection screen 11 can be a cloth screen, a wall, a white board, a blackboard, and a glass screen, but is not limited to this. In FIG. 1(a), the projector 10 is...

The invention provides a projector and a method for setting the projector, wherein the projector comprises the components of: an image projecting unit, a left sound channel loudspeaker, a right sound channel loudspeaker, a detecting unit and a processing unit. The detecting unit is used for determining operation manner of the projector. The processing unit is used for outputting sound signals in a manner that a right sound channel input sound signal received by the projector is used as a left sound channel output sound signal of the left sound channel loudspeaker and a left sound channel input sound signal received by the projector is used as a right sound channel output sound signal of the right sound channel loudspeaker when the projector is operated in a manner that the positive image is reversely placed and the mirror image is positively placed. Furthermore when the projected is operated in a manner that the mirror image is reversely placed and the positive image is positively placed, the left sound channel input sound signal is used as the left sound channel output sound signal, and the right sound channel input sound signal is used as the right sound channel output sound signal. The projector of the invention is provided with the left sound channel loudspeaker and the right sound channel loudspeaker for playing stereo sound. Furthermore setting of the loudspeakers can be automatically configured according to different placement positions of the projector.
Description
Technical field [0001] The invention relates to a projector, in particular to a setting method of the projector. Background technique [0002] Normal projectors can only provide mono speaker output, so the sound can only be played in mono. In addition, because the projector has only a mono design, it is impossible to further improve the sound quality to stereo or surround sound due to the hardware architecture. Furthermore, if the projector can provide stereo or multi-channel sound effects, it will be because the projector is placed in many different forms, such as placed on a table (that is, operated in an upright manner) or suspended from the ceiling. Up (ie inverted mode operation), so the sound effect of the projector needs to be set correspondingly. Therefore, there is an urgent need for a projector and an automatic sound setting method to overcome the above problems. Summary of the invention [0003] The purpose of the present invention is to automatically adjust the soun...
