摘要: In order to fix an optical fiber to a desired position in a holding member easily and tightly, provided is an optical collimator (10) having a plastic optical fiber (13) and a cylindrical holder (11). The holder (11) is configured to hold a collimator lens (12) at an end and has an insertion hole (11a) at an opposite end for inserting the plastic optical fiber (13). The plastic optical fiber (13) is sandwiched by an inner surface of a recess (11e) which is formed at a part of the holder (11) in proper alignment with the collimator lens (12).

摘要: A speaker unit is realized which directly drives a vibration plate having a low density, light weight, yet sufficient rigidity with a digital audio signal, and can thereby transmit vibration of a voice coil thereof to a carbonaceous acoustic vibration plate without loss. The present invention provides a digital speaker unit including a speaker body (14) comprising a carbonaceous acoustic vibration plate (25), a delta-sigma modulator (11) and a thermometer code conversion section (12) that convert a multi-value bit digital audio signal supplied from a digital sound source (10) to a digital signal with required bits, a plurality of voice coils (24) that cause to vibrate a plurality of the carbonaceous acoustic vibration plates (25) provided in accordance with the number of digital signal bits and a driver circuit (13) that individually drives each voice coil (24) based on the digital signal.

摘要: A carbonaceous acoustic diaphragm whose density is reduced while retaining the required stiffness is provided. Carbon nanofibers and spherical particles of PMMA are mixed into a carbon-containing resin such as a polyvinyl chloride resin, and the mixture is carbonized to vaporize the spherical particles of PMMA, thereby forming a porous structure having pores with the carbon nanofibers in a powdered form uniformly dispersed through amorphous carbon. By forming a multilayer structure by combining the porous layer with a layer that does not use PMMA, the density can be further reduced while retaining the stiffness.
