Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of projection devices, and particularly relates to a projector. Background Art
[0002] A projector, also known as a projection machine, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP.
[0003] Existing projectors, in order to facilitate angle adjustment, generally include a base and a projector body rotatably connected to the base. During use, the projector body can be rotated to adjust the projection angle.
[0004] However, for existing projectors, their bases are generally flat plates and support plates arranged on both sides of the flat plate, and their weights are relatively light, so the projectors are prone to tipping over. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a projector to solve the problem that existing projectors are prone to tipping over.
[0006] The utility model provides a projector, which includes a base, two support plates arranged at the upper end of the base, and a projector body rotatably connected to the two support plates. The projector body includes a housing, a projector module arranged in the housing, and a projection lens arranged at the front end of the housing. A wireless speaker is arranged in the base, and a sound outlet hole is arranged on the side of the base. The wireless speaker is wirelessly connected to the projector module.
[0007] For the above projector, by arranging a wireless speaker on the base, the weight of the base is increased, making the projector more stable when placed.
[0008] Further, a sliding groove is arranged on the housing, and the support plate is slidably connected to the sliding groove.
[0009] Further, the projector module includes a control circuit board, an analog-to-digital decoder, a memory chip, an image processor, and a digital signal processor.
[0010] Further, the projector module is located on the side of the housing close to the support plate.
[0011] Further, a plurality of first heat dissipation holes are arranged around the projection lens at the front end of the housing.
[0012] Further, a plurality of second heat dissipation holes are arranged at the tail of the housing.
[0013] Further, a USB interface connected to the projector module is provided at the tail of the housing.
[0014] Further, an HDMI interface and a power interface connected to the projector module are provided at the tail of the housing. Description of the Drawings
