Patent number: 10959005Abstract: A headphone in which the air pressure in a front cavity can be released to an external space, and whose characteristics in a low frequency range can be simply and finely adjusted is provided. The headphone includes: a driver unit; a baffle member holding the driver unit; the passage forming member attached to the baffle member and forming a vent passage with the baffle member; an ear pad defining a first space; and a cover member defining a second space. The baffle member includes: a first surface facing the first space; a second surface facing the second space; and a first through hole communicating with an internal space of the vent passage. The passage forming member includes a second through hole communicating with the internal space of the vent passage. The second space communicates with an external space of the cover member. The first space communicates with the second space through the first through hole, the vent passage, and the second through hole.Type: GrantFiled: December 24, 2019Date of Patent: March 23, 2021Assignee: AUDIO-TECHNICA CORPORATIONInventor: Daisuke Yoneyama

Publication number: 20200015000Abstract: The present invention provides an earphone having an improved balance between sound waves in a low-frequency range and in a high-frequency range. The earphone according to the present invention includes a diaphragm, and a sound emission surface that is spaced away from a front surface of the diaphragm. The sound emission surface includes a sound passing hole and a vent hole that sound waves generated by vibration of the diaphragm pass through. The sound emission surface is bulbous or dome shaped with a peripheral edge extending to a top part. The sound passing hole is disposed closer to the peripheral edge of the sound emission surface as compared to the vent hole. The vent hole is disposed closer to the top part of the sound emission surface as compared to the sound passing hole.Type: ApplicationFiled: July 2, 2019Publication date: January 9, 2020Inventors: Nonomi SHIWAKU, Daisuke YONEYAMA
