20080253604 | Ear speaker device - An ear speaker device includes an electroacoustic transducer including a housing mounted at a predetermined position of listener's head, a speaker unit mounted on one surface in the housing, and positioned away from an entrance of the listener's external acoustic meatus for a predetermined distance when the housing is mounted on the listener's head, and a tubular duct extended so as to allow a sound generated by the housing in the inner space thereof to reach the vicinity of the entrance of the listener's external acoustic meatus, and a hole for emitting sound of the duct is oriented to the opposite direction with respect to the entrance of the external acoustic meatus; and a mounting part used for mounting the electroacoustic transducer on the listener's head in a manner that the predetermined distance is provided between the speaker unit and the entrance of the listener's external acoustic meatus. | 10-16-2008 |
20090052716 | Ear Speaker Device - The ear speaker device includes a mount section that is provided with ear-hook sections, and rotation sections that rotate speaker movable sections with respect to the mount section. Tubular ducts are positioned more inside than the ear-hook sections in a natural state. When the ear speaker device is mounted, the speaker movable sections are rotated to the most outside positions. Then, the ear-hook sections are brought into contact with auricle base upper sections, respectively, and the speaker movable sections are rotated inwardly. In this manner, the tubular ducts can be positioned in the vicinity of the external acoustic meatus openings, respectively, of the listener without interfering with auricles and the like. | 02-26-2009 |
20090154755 | Electroacoustic Transducer and Ear Speaker Device - A reproduced sound of high quality is allowed to be listened to by a listener while natural sound image localization is provided. By providing a housing | 06-18-2009 |
20120177206 | EAR SPEAKER DEVICE - An ear speaker device includes an electroacoustic transducer including a housing mounted at a predetermined position of listener's head, a speaker unit mounted on one surface in the housing, and positioned away from an entrance of the listener's external acoustic meatus for a predetermined distance when the housing is mounted on the listener's head, and a tubular duct extended so as to allow a sound generated by the housing in the inner space thereof to reach the vicinity of the entrance of the listener's external acoustic meatus, and a hole for emitting sound of the duct is oriented to the opposite direction with respect to the entrance of the external acoustic meatus; and a mounting part used for mounting the electroacoustic transducer on the listener's head in a manner that the predetermined distance is provided between the speaker unit and the entrance of the listener's external acoustic meatus. | 07-12-2012 |
20120195440 | EARPHONE - A technology which improves frequency characteristics by an acoustic method so that, when a sound-isolating earphone is attached to a human ear, the sound is heard with natural frequency characteristics is provided. In a sound path from a diaphragm of an electro-acoustic transducer inside a sound-isolating earphone to the eardrum passing through a cylindrical sound leading pipe via the external auditory canal, two independent paths for sound waves are provided in the sound leading pipe, and transfer of the sound with a specific frequency is suppressed by adjusting a difference in length of the paths, whereby the frequency characteristics of the sound passing through this sound path are improved. | 08-02-2012 |
20120269312 | CORIUM COOLING STRUCTURE, REACTOR CONTAINMENT VESSEL PROVIDED WITH THE SAME, AND NUCLEAR POWER PLANT PROVIDED WITH THE SAME - An object is to provide a corium cooling structure that is capable of accumulating corium and debris that have flowed out from a reactor in small divided portions and of sufficiently cooling the high-temperature corium and debris, a reactor containment vessel provided with the same, and a nuclear power plant provided with the same. A capture portion that captures the corium that has flowed out from a reactor and a plurality of pipe portions that are provided in a coolant storing portion and into which the corium flows via the capture portion are provided. | 10-25-2012 |
20130159326 | SOLUTION MONITORING SYSTEM - A solution monitoring system is provided for gathering, filtering, and analyzing information associated with solutions for managing monitoring, upgrades, and migrations. Telemetry may be recorded for various types of solution events and various properties of solutions as part of an add-in intelligence. Furthermore, add-in management tools are provided for administrators and end users. | 06-20-2013 |
20130266170 | TWIN DRIVER EARPHONE - 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. | 10-10-2013 |
20140254855 | Ear Speaker Device - The ear speaker device includes a mount section that is provided with ear-hook sections, and rotation sections that rotate speaker movable sections with respect to the mount section. Tubular ducts are positioned more inside than the ear-hook sections in a natural state. When the ear speaker device is mounted, the speaker movable sections are rotated to the most outside positions. Then, the ear-hook sections are brought into contact with auricle base upper sections, respectively, and the speaker movable sections are rotated inwardly. In this manner, the tubular ducts can be positioned in the vicinity of the external acoustic meatus openings, respectively, of the listener without interfering with auricles and the like. | 09-11-2014 |
