摘要： A magnetic circuit for a speaker device includes: a yoke which has magnetism and has a center pole formed into a column shape; and plural flat plate-shaped magnets which are uniformly arranged around the center pole and form a magnetic gap with the center pole. Each of the magnets is magnetized in a direction in parallel with a thickness direction and in a direction of the center pole. The magnetic circuit for the speaker device is a radial-type magnetic circuit. Since each of the flat plate-shaped magnets is formed not into a circular arc shape but into a flat plate shape, it becomes easy to form the magnets, and the number of procedures of forming of the magnets can be reduced. Additionally, since each of the flat plate-shaped magnets is magnetized in the thickness direction, a special magnetization machine becomes unnecessary. Thus, the number of procedures of magnetizing of the flat plate-shaped magnets can be reduced. As a result, the manufacturing cost of the magnetic circuit can be reduced.

摘要： A speaker device includes a diaphragm having an inner rim connected to a voice coil bobbin and an outer rim connected to a frame through an edge, wherein the diaphragm is shaped so that a peak portion is formed with an acute angle folded back between the inner rim and the outer rim which are positioned at an acoustic radiation side in comparison with the peak portion. The cross-sectional shape of the diaphragm extending from the peak portion to the inner rim is formed with a convex shape toward an acoustic radiation side, and also that of the diaphragm extending from the peak portion to the outer rim is formed with substantially straight shape or convex shape toward the acoustic radiation side. The speaker device lower in profile allows high-quality sound to be reproduced, in particular, the high range of frequency characteristic of the sound pressure to be improved.

摘要： A repulsive-type magnetic circuit prevents deterioration of magnetic characteristic of magnets due to heat accumulation, and includes: a magnet and plural magnets arranged such that matching poles of the magnet and each of the plural magnets confront each other; a yoke; a pole piece; and a top plate. The pole piece is above the yoke. The top plate is above the pole piece. The magnet is between the yoke and the pole piece. The plural magnets are arranged between the pole piece and top plate. Joule heat generated by the voice coil is hardly propagated, as radiant heat, to one of the plural magnets on the side near the top plate. Accordingly, the temperature of the magnet on the top plate side hardly rises even if radiant heat continuously propagates to the pole piece. This prevents demagnetization of each of the plural magnets, and deterioration of the magnetic characteristics thereof.
摘要翻译：排斥型磁路防止由于热积聚导致的磁体的磁特性的劣化，并且包括：磁体和多个磁体，其布置成使得磁体和多个磁体中的每一个的匹配磁极彼此面对; 一个轭极片和顶板。极片在轭之上。顶板位于极片之上。磁体位于磁轭和极片之间。多个磁铁布置在极片和顶板之间。由音圈产生的焦耳热几乎不会作为辐射热传播到靠近顶板的一侧的多个磁体之一。因此，即使辐射热连续地传播到极靴，顶板侧的磁体的温度也难以上升。这防止了多个磁体中的每个磁体的退磁和其磁特性的劣化。

摘要： A speaker device includes an acoustic capacity unit; an acoustic pipe connected to the acoustic capacity unit; and a driving speaker attached to the acoustic capacity unit. The acoustic capacity unit and the acoustic pipe constitute the Helmholtz resonator, and resonate at a predetermined Helmholtz resonant frequency. On the other hand, the acoustic pipe itself has a resonant frequency. By setting the resonant frequency of the acoustic pipe to be 0.5 to 2.5 octaves higher than the Helmholtz resonant frequency, the speaker device can be obtained which outputs signals of continuous frequency band from the Helmholtz resonant frequency to the resonant frequency of the acoustic pipe.

摘要： An internal magnetic circuit is formed by a plate forming a pole piece, a vertically magnetized magnet attached to a bottom face of the plate, and a yoke attached to a bottom face of the magnet. A magnetic gap is formed between the plate and the yoke. The yoke includes a bottom part attached to the bottom face of the magnet, a side part standing on the side of the plate, and a folded-back part folding downwards over the side part to face the magnetic gap. Thus, the internal magnetic circuit having a uniform magnetic flux density inside the magnetic gap along the direction of its length is provided.

摘要： A speaker device where the dip in the middle sound range is reduced, which provides reproduced sound of comparatively high quality, and provides reproduced sound of comparatively high sound pressure. In the speaker device, a support member for a speaker vibrator is adopted for an edge. The speaker device has a movable part (85) having bent parts, or more specifically, having a top bent part, an inner bent part, and an outer bent part. Because the movable part (85) is formed such that the top bent part is positioned closer to the radial center of the speaker device than the radial center between the inner bent part and the outer bent part, the edge (8) has comparatively high rigidity. Consequently, the dip in the middle sound range can be reduced by a simple structure without forming, for example, a damping agent layer and a resin layer on the support member for a speaker vibrator.
摘要翻译：一种扬声器装置，其中在中间声音范围内的倾角减小，这提供了较高质量的再现声音，并且提供了较高声压的再现声音。在扬声器装置中，用于扬声器振动器的支撑构件用于边缘。扬声器装置具有具有弯曲部分的可移动部分（85），更具体地说，具有顶部弯曲部分，内部弯曲部分和外侧弯曲部分。由于可动部（85）形成为使得顶部弯曲部位于比内侧弯曲部与外部弯曲部之间的径向中心更靠近扬声器装置的径向中心的位置，所以边缘（8）具有较高的刚度。因此，可以通过简单的结构减少中间声音范围的倾斜，而不会在扬声器振动器的支撑构件上形成例如阻尼剂层和树脂层。
