Abstract

The invention discloses a light amplifier for teaching. The light amplifier for teaching comprises an amplifier casing and an earplug, wherein a loudspeaker is arranged on the front surface of the loudspeaker casing; an operation interface is mounted above the loudspeaker; a volume adjusting knob is mounted on one side of the upper surface of the amplifier casing; a switch knob is mounted in the middle of the upper surface of the amplifier casing; a USB socket is formed at the upper part of one side of the amplifier casing; a charging indication lamp is arranged below the USB socket; a charging socket is formed on one side of the amplifier casing and below the charging indication lamp; a battery cover is mounted on one side of the amplifier casing; a socket is formed at the lower part of one side of the amplifier casing; and a processor is mounted on a wire. The light amplifier for teaching has the advantages that the structure is simple; the phenomenon that teaching is affected by a dead battery is avoided; the remaining battery power can be clearly seen, so that the battery can be charged or replaced in time; and students can be more concentrated, so that the learning efficiency is improved.
