摘要： The present invention relates to a so-called bass-reflex electroacoustic transducing apparatus, wherein a plurality of sound ducts (ports) having the same equivalent mass and different lengths are provided in communication with a housing which incorporates therein an electroacoustic transducing element. Thus, resonance and antiresonance generated in respective sound ducts cancel each other out, thereby preventing a tone quality of a reproduced sound from being deteriorated.

摘要： A speaker apparatus includes a yoke formed of a magnetic material and having a flange portion and a center pole protruded integrally forwards from a mid portion of the flange portion, and a ring-shaped driving magnet into which the center pole is inserted. The speaker apparatus also includes a top plate mounted on the driving magnet. The top plate is formed of a magnetic material and the center pole is inserted through the top plate. The top plate defines a magnetic gap together with the center pole. The speaker apparatus further includes a voice coil mounted on a bobbin secured to a diaphragm in the magnetic gap, and a canceling magnet arranged on the outer periphery of and spaced from the driving magnet at a pre-set spacing for covering the driving magnet. The canceling magnet cancels the magnetic flux leaking to outside a magnetic circuit including the driving magnet.

摘要： An electro-acoustic transducer, such as a speaker device or an earphone device. Includes an electro-acoustic transducing unit, such as a speaker unit, for converting input electrical signals into sound, a casing in which the electro-acoustic transducing unit is arranged and which delimits a back cavity towards the rear side of the electro-acoustic transducing unit, and at least two openings having a sound duct communicating with the back cavity. The sound radiated from the back surface of the electro-acoustic transducing unit is attenuated by being transmitted into the inside of the sound duct to prevent the radiated sound from being re-admitted into the electro-acoustic transducer.

摘要： Provided is a technique for improving frequency characteristics by an acoustics-related method so that a sound is heard with natural frequency characteristics when a sound-isolating earphone is fitted in a human ear. A sound-isolating earphone is provided with two or more electroacoustic transducers, wherein independently generated sound waves are passed through isolated sound leading pipes and are mixed just before an entrance of an external auditory canal, and a sound wave of which is twice the difference between path lengths of the two sound leading pipes is attenuated. This serves to provide an easy-to-hear improved sound quality by suppressing the sound wave at around 6 kHz that is transmitted with characteristically high intensity in a sound-isolating earphone.

摘要： An electroacoustic transducer apparatus of a type that it is inserted into a cavum concha upon use. The electroacoustic transducer apparatus of the invention is applied to a headphone of a so-called in-the-eart type or so-called inner-ear type. This headphone is provided with an air passage portion formed through an elastic ring member attached to the outer peripheral portion of the housing so as to communicate the inside and outside portions of a concave portion of the cavum concha upon use. Accordingly, a certain amount of sound escapes to the outside, thereby obtaining the acoustic characteristics of substantially the same level from a low band to a high band regardless of the size of the user's ears.
