PLASTIC UKULELE

A molded plastic ukulele disclosed by the present invention comprises a sound board, a fret board, a head plate and a lower half of the body. The sound board, fret board, head plate are integrated with the lower half of the body into a complete ukulele body through the way of the sound board tongue, fret board tongue, head plate tongue being sequentially mounted on to the corresponding grooves of the lower half of the body. Attached to the bottom surface of the sound board are two paralleled outline reinforcing ribs which are in parallel with the outline of sound board on the inside. The sound board has a sound hole in the upper middle part. Around the sound hole are two sets of lengthwise and widthwise paralleled reinforcing ribs. The part of sound board which is surrounded by the lower widthwise reinforcing ribs and the lower bout of outline reinforcing ribs is resonance section with a thickness of 1.0-1.4mm only. Attached to the bottom surface of resonance section is a grid bracing structure in a one-piece molding with the sound board.This invention has achieved the effects of not only generating louder sound volume, richer timbre with comparison to those poor-to-mediocre conventional wooden ukuleles, but also having the advantages of simplified process fitting for mass production and all-weather playing, lower production cost by creating the super-thin but firmly-structured resonance section which is not able to accomplish by prior art.
