The invention discloses a voice remote controller and a power supply method thereof. The voice remote controller comprises a noise acquisition module which is used for acquiring environmental noise around the voice remote controller through a sound aperture array, an acoustic-electric conversion module which is used for converting the environmental noise acquired by the noise acquisition module into electrical signals, and an energy storage module which is used for storing the electrical signals converted by the environmental noise through the acoustic-electric conversion module as electrical energy and used for supplying power to the voice remote controller. Through the sound aperture array, the environmental noise is acquired and converted into the electrical energy as a work energy source, so that battery replacement or frequent charging is avoided; when the voice function of the voice remote controller is turned off, the acquired environmental noise is totally converted into the electrical energy, so that the energy utilization ratio is increased; through adjusting the number of opened sound apertures in the sound aperture array, a noise acquisition angle is changed, and the environmental noise is separated from a voice signal of a user, so that a noise waveform can be reversedly superimposed onto the voice signal to filter out the environmental noise in the voice signal, and adverse effects of the environmental noise on the voice remote controller are reduced.

A three-dimensional adjustment device of a manual or semi-automatic work table is composed of a Z-direction adjustment mechanism, an X-direction adjustment mechanism, a Y-direction adjustment mechanism, a theta-angle adjustment mechanism and a locking mechanism. A cylinder of low cost and high reliability, a sliding bearing, a micrometer head, a spring and other purchased parts are reasonably used. The three-dimensional adjustment device is simple and compact in mechanical structure design and low in machining cost and has low requirements for machining equipment, and the shape of the parts is simple, manufacturing cost of the three-dimensional adjustment device is reduced more than ten times than that of a traditional three-dimensional adjustment device, and use cost is greatly saved. The three-dimensional adjustment device is suitable for a work table of manual or semi-automatic equipment requiring the three-dimensional adjustment function and also suitable for other devices requiring three-dimensional adjustment. According to the three-dimensional adjustment device, total equipment cost is greatly reduced, the market share is improved, and the three-dimensional adjustment device can be used for adjusting the Z-direction, the X-direction, the Y-direction and the theta-angle of the work table, and is wide in application range and high in application value. According to the three-dimensional adjustment device, the drive method is simple, adjustment is convenient to achieve and adjustment precision is high.
