An oscillation-preventing member for a stylus-tip protector is provided with a base member and a pair of leg parts integrally formed by employing a flexible sheet material. The pair of leg parts is bent at the same angle and in the same direction with respect to the base member. This oscillation-preventing member is mounted on a cartridge body, sandwiching a cartridge case from both outer sides with the pair of leg parts to prevent oscillation of a stylus-tip protector by bringing the base member into contact with part of the stylus-tip protector. This structure allows to provide an oscillation-preventing member for a stylus-tip protector, being attached/detached easily, manufactured at low costs, and configured to reliably prevent oscillation of a stylus-tip protector according to an impact.

Provided is a beamforming microphone system capable of reducing a processing load caused by computation of directivity and flexibly setting an area where sound is picked up. A beamforming microphone system (1) according to the present invention includes: a plurality of microphone units (11); a signal processing unit (12) that processes a sound pickup signal from each of the microphone units at each predetermined time; and a storage (13) that associates, for each sound pickup area, sound pickup area information with individual-sound-pickup-area position information freely set within the sound pickup area and stores the associated information. The signal processing unit includes a position information identification unit (121) that identifies sound source position information, a signal generation unit (123) that generates the sound signal corresponding to the sound from the sound source position, and a channel assignment unit (125) that assigns an output channel, based on the individual-sound-pickup-area position information on the individual sound pickup area to which the sound source position belongs.
