Abstract
A micromachined gyroscope and an electronic product are provided. The micromachined gyroscope includes a driving component, a detecting component, first connecting components, and second connecting components. The driving component includes first driving pieces, second driving pieces, and driving devices driving the first driving pieces and the second driving piece to move. The detecting component includes first detecting pieces arranged along a third direction, second detecting pieces arranged along a fourth direction, and detecting devices for detecting movement distances of the first detecting pieces and/or the second detecting pieces along a fifth direction. Each of the first connecting pieces and the second connecting pieces rotates around a center thereof, so the second detecting pieces and the first detecting pieces respectively reciprocate along the third direction and the fourth direction. The micromachined gyroscope and the electronic product realize differential detection and effectively avoid influence of acceleration shock and quadrature error.
