Abstract: An electronic device includes a vibration generation unit configured to generate vibration and a switching unit configured to perform switching between a first mode for causing the vibration generation unit to generate the vibration on the basis of first vibration information including information indicating an amplitude and a frequency, and a second mode for causing the vibration generation unit to generate the vibration on the basis of second vibration information including information indicating an amplitude and a frequency, wherein the second vibration information is data obtained by reducing an amplitude of a predetermined frequency band in the first vibration information.

Abstract: An object of the invention is to provide composite graphite particles (C) for nonaqueous-secondary-battery negative electrode, wherein metallic particle (B) capable of alloying with Li are present in inner parts thereof in a large amount. The invention relates to a composite graphite particle (C) for nonaqueous-secondary-battery negative electrode, the composite graphite particle (C) comprising a graphite (A) and a metallic particle (B) capable of alloying with Li, wherein when a section of the composite graphite particle (C) is examined with a scanning electron microscope, a folded structure of the graphite (A) is observed and a presence ratio of the metallic particle (B) in the composite graphite particle (C), as calculated by a specific measuring method, is 0.2 or higher.
