Patent number: 11076233Abstract: Provided is a sound generation device wherein noise can be reduced in accordance with a predetermined frequency band. An elastic member (8) is provided to obtain a sound pressure characteristic having a sub-peak at a predetermined frequency on the lower side than a lowest resonance frequency, and a phase characteristic such that a change rate of phase difference is lowered around the predetermined frequency. When the phase characteristic is calculated by simulation or actually measured in advance and an input signal is controlled such that the generated sound has an opposite phase to the noise, the generated sound can be made less prone to deviate from the opposite phase to the noise even if a time difference is caused between noise sound collection and sound generation at around the predetermined frequency, with the result that the noise can be effectively reduced.Type: GrantFiled: September 13, 2016Date of Patent: July 27, 2021Assignees: PIONEER CORPORATION, TOHOKU PIONEER CORPORATIONInventors: Satoru Hiwatari, Hiroyuki Dohi, Koji Takayama, Hiroyuki Kobayashi

Patent number: 10779076Abstract: A damper and a speaker apparatus includes the damper, which suppresses damage to an oscillatory system from an excessive input signal, enabling an efficiency increase of the speaker apparatus. As a damper has a planar surface, undue deformation of the oscillatory system due to an excessive input signal is suppressed, and damage to the oscillatory system can be suppressed. Furthermore, since the deformation of a corrugation portion by a normal input signal is hardly prevented, a reduction in sound pressure of the speaker apparatus with respect to an input signal is suppressed, enabling an increase in efficiency. Furthermore, the planar surface is extended at a height in a thickness direction different from that of an attachment portion. Thus, rising portions are deformed when a voice coil bobbin is oscillated, enabling suppression of rupture of the damper in the vicinity of a boundary between the planar surface and the attachment portion.Type: GrantFiled: December 14, 2018Date of Patent: September 15, 2020Assignees: PIONEER CORPORATION, TOHOKU PIONEER CORPORATIONInventor: Yoshihiro Kimura
