Projector and galvanometer assembly used in conjunction with it

Abstract

The invention belongs to the technical field of projectors, and in particular relates to a projector and a vibrating mirror assembly used in conjunction with it, including a projector body and a vibrating mirror assembly, the vibrating mirror assembly is externally placed at the light outlet of the projector body, the The vibrating mirror assembly includes a housing connected to the projector body, a driver is arranged in the housing, a vibrator is connected to the driver, a lens is arranged in the middle of the vibrator, and the lens corresponds to the light outlet of the projector body , the driver drives the vibrator to generate vibration. The purpose is to place the vibrating mirror outside, so that the vibrating mirror does not have to withstand the high temperature inside the optical machine, and the requirements for the use of high-temperature resistant materials for the vibrating mirror are not high, which reduces the processing cost of the vibrating mirror; and after the vibrating mirror is placed outside, the original Part of the functions or circuits of the projector is transferred out, which reduces the size of the projector as a whole and meets the market's demand for smaller and smaller projectors.

Problems solved by technology

[0002] The galvanometer is a part of the optical machine of the projector. The current assembly scheme is to install the galvanometer directly in the projector for use. However, when the galvanometer is installed inside the projector for use, due to the high temperature inside the optical machine, the galvanometer will The components inside will heat up due to the influence of temperature, which will affect the use of the vibrating mirror. Therefore, there are high requirements for the selection of the vibrating mirror material, which makes the processing cost of the vibrating mirror higher.

Moreover, the galvanometer is an internal component of the projector optical engine, and there is no way to disassemble it. Therefore, when it is sold, it is bundled with the projector, and users cannot make choices according to their own needs.

[0003] At present, the galvanometer is not used as a finished product for external use alone. Different galvanometer solutions can be selected according to the user's use. When the user needs to improve the experience, he has to buy a new projector; now the market is for The demand for the projector is to make the projector smaller and smaller so that it is easy to carry around. The problem is that the design space of the galvanometer is getting narrower, and the sealed environment inside the optical machine is not conducive to the heat dissipation of the galvanometer.
