摘要： PROBLEM TO BE SOLVED: To provide a headphone which can give fitting comfort to a user, can be made to be compact, and especially can prevent the fitting comfort from being impaired at all and improve it if possible.
SOLUTION: The headphone (1) is provided with an arcuate portion (2) and two ear pads (3). On the basis of a Cartesian spatial system, a rotating shaft (R) forming an angle of at least 10°, advantageously at least 15°, between each of the three planes is provided between the headphone arc portion and a joint type suspension portion of each of the ear pads (3), depending on each of the ear pads (3), to couple the headphone arc portion with the each of the ear pads (3). The Cartesian spatial system consists of an X, a Y and a Z planes. The Z plane is a symmetrical plane of the headphone, an Y plane is a plane which extends perpendicularly to the Z plane to cross the center of the arc portion, and an X plane is a plane which crosses both the defined planes at right angles and has an arbitrary height.

摘要： PROBLEM TO BE SOLVED: To improve mechanical design of a transducer so as to produce a fully automatic transducer, particularly, an extremely miniaturized transducer whose diameter is 10mm or less, without much costs and quality deterioration of the transducer.
SOLUTION: In a miniaturized acoustic transducer (1) based on electrodynamic principals including a housing (6) composed of a deeply drawn steel plate, a magnet mechanism part (4) with a magnet (9) and a diaphragm (14) equipped with a coil (13) wherein a wire (5) communicated to a contact portion (15) is pulled out. The housing (6) with the outer diameter of 20mm at a maximum is composed of a thin steel plate with the average thickness of 0.2mm at a maximum, the magnet mechanism part (4) includes a lower magnetic pole plate and an upper magnetic pole plate (10), and the magnetic plate (10) is composed of a steel plate with at least 1.5-fold thickness of the average thickness for the base of the housing (6). In one embodiment, the magnet system includes a magnetic cup (8) in place of the lower magnetic pole plate. A method for producing such a sort of transducer is also intended.

摘要： PROBLEM TO BE SOLVED: To obtain an enclosed small-sized microphone with moisture proof. SOLUTION: The small-sized microphone 1 is provided with a front plate 9, a seating 2 and a side part 3 that is placed between them and provided with at least an opening 3a. Covering the opening 3a with diaphragms 3', 3" forms an internal space 7 in the interior of the microphone 1. Then the internal space 7 is communicated with a balanced space 8 with a material having a high acoustic impedance and a slacked membrane 6 encloses the balanced space 8 with moisture proof against the outside of the membrane 6.

摘要： PROBLEM TO BE SOLVED: To provide a geometric distribution of the intensity of the electrical field between an electrode and a diaphragm of an electrostatic transducer, which can vary within a wide range in accordance with the wishes of a manufacturer or a user with respect to a static electrode transducer, which operates in accordance with the electret principle and a static electrode transducer which operates in accordance with the capacitor principle. SOLUTION: An eletrostatic microphone capsule includes a diaphragm which is exposed to a sound field and is excited to oscillate by this sound field, and an electrode (1) arranged at a distance from the diaphragm. The electrode (1) has at least two areas (4, 5) having different charge densities. Advantageously, at least both the areas (4, 5) consist of an at least essentially circular area (4) and an at least essentially annular area (5).

摘要： PROBLEM TO BE SOLVED: To enhance durability of a varnish-coated wire having a non-round cross section. SOLUTION: This varnish-coated wire 1 is composed of a metal wire 2 and a varnish coat 3 surrounding the metal wire, and has a cross section having two axes different in length and vertical to each other for particularly manufacturing an electric coil. The varnish coat 3 is located on the side belonging to the longer cross-sectional axis and has a thickness less than the side belonging to the shorter cross-sectional axis. The wire has a cross section having an axis ratio of 3:1 at the maximum. In a manufacturing method of the varnish- coated wire composed of the metal wire 1 and the varnish coat 3 including an insulation characteristic and a baked varnish characteristic and surrounding the metal wire, and having the cross section having two axes different in length and vertical to each other, a varnish-coated wire having a round cross section is so pressed as to have a cross section having an axis ratio of 3:1 at the maximum by a rolling method, and the wire may have an elliptical cross section.
