A multifunctional projector support

Abstract

The invention belongs to the field of projection equipment, and more specifically relates to a multifunctional projector support comprising a pedestal, a first connecting rod, a second connecting rod and a bracket. The pedestal is connected to the lower end of the first connecting rod. The upper end of the first connecting rod is connected with the lower end of the second connecting rod, and the upper end of the second connecting rod is connected with the bottom portion of the bracket. The multifunctional projector support is characterized in that a power supply module is installed in the pedestal; a loudspeaker and a wired microphone are arranged on the outside of the bracket; the wired microphone transmits a sound signal to a loudspeaker output terminal; the microphone and the loudspeaker are separately connected with the power supply module; the power supply module output terminal is connected to a 220v AC power supply; and the output terminal supplies electric power to the wired microphone and the loudspeaker. According to the invention, the height and the shooting angle of the mobile projector can be adjusted; the structure is simple, and heat radiation is realized; the microphone and the loudspeaker are integrated; and conference lecture and displaying are provided with convenience.

[0003] As projectors are used more and more widely, movable projectors are more popular in the market than fixed projectors. However, due to the environment and mobile projector equipment, the projection cannot accurately project information to the screen. In general, when using a mobile projector to make a conference speech, a projector bracket is often needed, and in a larger conference environment, a mobile projector often needs to be combined with more multimedia equipment to complete the conference presentation and speech

The brackets for mobile projectors on the market are often limited to mobile phone brackets, which are very simple and have no special functions
