本願は、平面振動板全面に対して均一に近い駆動力を与

二で振幅の大きい所と振幅が非常に小さい所ができる)
のできる度合いは振動板がハニカ・ム構造体で造られて
いるという理由から、コーン型に比べ小さい。Recently, flat diaphragm speakers have been developed that have lower distortion than cone speakers. This speaker uses five drive units (conventional speaker drive devices) to drive five locations (center and four corners) on the back of the diaphragm. Since this speaker has a flat diaphragm, phase distortion is improved compared to cone speakers. Also, nodes and antinodes (nodes and antinodes in terms of waves, i.e., the diaphragm surface) that occur on the diaphragm surface.
2 creates areas with large amplitude and areas with very small amplitude)
Because the diaphragm is made of a honeycomb structure, the degree of vibration is smaller than that of a cone type.
しかしながら、依然として節や腹は存在している。However, nodes and belly still exist.
即ち、振動板面は寄生振動が存在している。That is, parasitic vibration exists on the diaphragm surface.
本発明は、振動板面上の寄生振動をなくす為、振動板全
体にわたって、均一に近い駆動力を与えるものである。The present invention provides nearly uniform driving force over the entire diaphragm in order to eliminate parasitic vibrations on the diaphragm surface.

い駆動力を与える。次に振動系の作製の手順を述べる。Figure 1 shows the current direction (Figures 1, 4, The arrows in FIG. 5 indicate the current direction). S and N in the figure indicate the polarity of the magnetic poles. As you can see from this figure, each voice coil receives a force in the same direction. Figure 2 shows a schematic cross-section parallel to the axis of the speaker and parallel to the arrangement of the magnets. A unit (Figure 3) in which a voice coil 2 is wound around a rectangular bobbin 1 is adhered with an adhesive 3, and a diaphragm 4 is adhered to it. A loop is formed in the magnetic circuit by the magnet 6, the magnetic circuit flat plate 7, the magnet, the magnetic circuit square column 5, the gap between the opposing magnetic circuits (the space in which the voice coil is inserted), and the magnetic circuit square column. A large number of such magnetic circuits are formed (see the magnetic pole arrangement of the square prism of the magnetic circuit in Figure 1). As shown in this figure, each voice coil is driven in parallel to provide nearly uniform driving force to the entire plane diaphragm. Next, we will describe the procedure for creating the vibration system.

い合う面ができるので理想的でない。[Claims] Square prism magnets are arranged in m rows and n columns on a rectangular flat plate of magnetic circuit material (for example, pure iron) of appropriate thickness so that the polarity of the magnetic poles is alternately reversed. , and then stand and join them at certain intervals. Then, a rectangular prism-shaped magnetic circuit material with a larger cross-sectional area (section perpendicular to the axis) than the magnet is bonded to the upper end of each magnet. The gaps between adjacent rectangular prisms, which are the individual magnetic circuit materials, ie, the vertical and horizontal gaps created like lines on the base, are used as spaces for applying force to the voice coil. The vibration system consists of a unit in which a voice coil is wound around a rectangular cylindrical bobbin, which is glued in all 111 rows and n columns, and a diaphragm is glued to one end of the shaft of the bobbin. The voice coils are connected in series and in parallel so as to have an appropriate impedance, and the coils are connected with polarity so that the forces acting on each voice coil are in the same direction. The above description is about the combination of a square prism magnetic circuit (the magnet should be the same square prism as the magnetic circuit) and a rectangular tube bobbin, but it can also be done with a combination of a triangular prism and a triangular tube, or a combination of a hexagonal prism and a hexagonal tube. However, in the case of a hexagonal prism,
Adjacent surfaces of magnetic poles cannot always have opposite polarities, but they can have opposite surfaces with the same polarity, which is not ideal.
