First, the shortcomings of the conventional type are (1) (2) A horn-type or dome-type method that drives the periphery of a hemisphere, and is not a full-scale drive that drives the entire diaphragm like a condenser type. Naturally, the use of a hard diaphragm increases the mass, and since the diaphragm has a unique frequency, there is a risk that it will resonate at that frequency, causing peaks and dips. Particularly in the case of a cone type, distortion due to the Doppler effect and split vibration cannot be avoided. This shows that the ideal speaker is a full-plane drive system using a soft vibrating membrane. This is not surprising since this method is already commercially available. However, the present invention is fundamentally different from those already on the market in that it has complete breathing motion, full-scale drive, 360 degree omnidirectionality, and above all, high efficiency. It is also possible to expect a wider band. (For simple breathing movements, there are commercially available soft dome speakers, but these are breathing movements that utilize changes in atmospheric pressure and are different from the pure electrical breathing movements of the present invention.) Let's get into the details.

Figure 2) is a sub-sectional view of the basic principle, and Figure 2 is a cross-sectional view. That is, a large number of small magnets of the same shape and magnetic force are collected and arranged in two layers on a concentric circle as a group of cylindrical magnets with different diameters. Then, as shown in Figure 1, the magnetic poles N and N and S and S form a magnetic circuit in which they repel each other, and within this magnetic circuit there is a cylindrical shape printed with a conducting wire wound like a solenoid that becomes the voice coil. A vibrating membrane is arranged. Now, when a voice current is passed through this voice coil, it expands in one half cycle as shown in Figure 3.
In the remaining half cycle, contraction (Figure 4)
do. Actually, since the cylindrical diaphragm does not expand or contract, it is provided with irregularities as shown in Fig. 5. In this way, the movement of expansion and contraction, that is, the breathing movement, is performed. This speaker may also be of a cone type, as shown in Fig. 6, in which one side of the cylinder has a small diameter and the other side has a large diameter. Also, as shown in Fig. 7, a type of amorphous shape may be considered, although the size and shape of both ends of the cylindrical shape do not change, but in any case, the basic shape is the same as the cylindrical shape.

ある。 Now, sound waves are generated by the movement of expansion and contraction of the cylindrical diaphragm 3, and from the above, naturally (1) the present invention is completely non-directional in the horizontal 360 degree direction. (2) Perform full-fledged electrical breathing exercises of expansion and contraction. (3) Full-scale drive. (4) Since the solenoid-like voice coil is used by turning the conductor many times, it is easy to secure an impedance of 4 to 16 ohms, so no matching transformer is required.
There are advantages such as However, this is only the elementary stage of the present invention (Fig. 8) and later (Fig. 9).
is the reaching point. Let's start with the one closest to the goal of the present invention (FIG. 8). First (Fig. 8A), a large number of flat and rectangular magnets with equal magnetic force and the same configuration are collected, and the same polarity faces each other with a certain distance apart to create a mutually repelling magnetic field. Various cylindrical shapes such as a cylinder, an elongated cylinder, and a prism are constructed while taking the magnetic pole direction as the vertical axis. (A, B, and C in Figure 8B).
Note that this configuration is completely different from the magnet arrangements shown in FIG. 1 to FIG. 7. (Figure 1) ~
In (Fig. 7), two cylindrical groups of magnets with different diameters arranged on a concentric circle form mutually repelling magnetic fields, but in (Fig. 8), two cylindrical groups arranged on a concentric circle form a mutually repelling magnetic field.
There are no groups of magnets; there is only one cylindrical shape that is identical in that respect. Since the magnets form a mutually repelling magnetic field in the circumferential direction of this one cylindrical shape, the circuits (FIG. 1) to (FIG. 7) are different from a magnetic circuit. Now, in this case (FIG. 8), the magnetic pole direction is aligned so as to be parallel to both sides of the cylindrical structure made up of a large number of magnets 1 (both openings of the cylindrical structure, since it is cylindrical with no bottom or ceiling). This group of cylindrical magnets is arranged in series in the same direction with respect to the vertical axis of the cylindrical shape, that is, the direction of the magnetic poles, and the positions of the individual magnets 1 are also aligned, and then another magnet 1 of the same shape is placed in series. Magnet groups 1 of the same magnetic circuit are connected using small rods or plates made of non-magnetic material while leaving gaps that allow air to enter and exit. (D in Figure 8B) Stack these in several more layers. Then, the voice coil 2 is printed on the cylindrical diaphragm 3 as shown in (FIG. 8C) by the number of gaps and the width of the gaps in the stages of the magnet group as shown in FIG. 8B (E). In other words, in the case of this figure, 3
There are three gaps, so print VC1, VC2, VC3. The width of one voice coil 2 is set to a width that allows the magnetic field of the magnetic circuit to pass through. This is formed into an accordion curtain shape as shown in FIG. 8D (a) and inserted between the mutually repelling magnetic circuits of the magnet 1. In other words, it enters the waveform. (B in Fig. 8D) is an enlarged view of that part. (C in FIG. 8D) is a side view. In this way, in one half period of the audio signal, the folds of the diaphragm 3 become narrower on the outside of the cylindrical shape, as shown in FIG. 8E, and in the opposite half period, as shown in FIG. On the outside, the vibration membrane moves so that its folds become wider. Note that this operation is the opposite on the inside of the cylinder. In other words, it expands and contracts. This is a different point from the operations shown in FIG. 1 to FIG. 7. At this time, the voice coil 2 must be designed so that it is located in the gap between each of the cylindrical magnet groups 1 arranged vertically. (Figure 8G). Also, with this method, no magnetic field is applied to the voice coil 2 as indicated by the arrow in FIG. 8H, resulting in a corresponding loss of power. Therefore, we placed magnets at the curves as well, creating a highly efficient dual-action speaker that is completely different from previous speakers (Figure 9).
This whole thing (FIG. 9) is the pinnacle and completion point of the present invention. Therefore, (Fig. 1) to (Fig. 8) are merely explanations to arrive at this (Fig. 9). Now, (Fig. 9A) is a diagram in which magnets are also added to the arrows in (Fig. 8H).

Assume that the magnet 4 is a telescopic magnet 4, and the magnet added from (FIG. 9) is a magnet 5 that moves back and forth.

る。 Now, the newly added back and forth motion magnet 5
As shown in FIG. 9A, the back-and-forth motion magnets 5 are placed alternately on the inside and outside of the cylindrical form of the telescoping magnet 4, and one for each telescoping magnet. Arrange comrades of the same polarity to face each other and repel each other, with a distance of . (Figure 9B). The entire group of cylindrical magnets created in this way is considered as one group.
A group of magnets with exactly the same shape and the same magnetic circuit as this group are arranged in series in the same direction as the magnetic pole direction of the previous group. At this time, both magnet groups should be aligned and arranged in series with a certain gap that allows air to enter and exit. (Figure 9C).
In other words, this is the same arrangement as (D in Figure 8B). Stack this up several times. (D in Figure 9). This is also the same stacking method as (e in Figure 8B). The figure shows only an enlarged view of the part. Now, a cylindrical diaphragm 3 is attached to the magnetic circuit created in this way.
A voice coil 2 is printed on the wafer, formed into an accordion curtain shape, and inserted between the mutually repelling magnetic circuits of the group of magnets, as shown in FIG. 9E. At this time, the rice cake theory (Figure 8B
As mentioned in (e), the number of voice coils 2 is printed as many times as there are gaps between the steps of this cylindrical magnet group, and the voice coils 2 are made to enter the magnetic field of the lines of magnetic force flowing between the gaps between the steps. i.e. 4
If there are 3 levels, there will be 3 gaps, and if there are 3 levels, there will be 2 gaps, so print according to the number and position of the gaps. When an audio current is applied to the cylindrical speaker thus created (see Fig. 8), it behaves in ways that were unimaginable. In other words, the movement in (Fig. 8) was only an expansion/contraction movement, but in (Fig. 9), back and forth movement is added to this, and the two movements have a synergistic effect, resulting in even higher efficiency. This is a double action. What kind of action will it take? (Fig. 9F) represents the first half period of the audio signal, and at this time, the diaphragm 3 narrows the interval between its folds (outside the cylindrical form), so the air pressure inside the folds increases, and in addition, Since it is also pushed forward, the air pressure increases doubly. It is a synergistic effect. (This operation is exactly the opposite inside the cylindrical form.) However, if the input of the speaker is connected in reverse, the above operation will be reversed. (Operation in the lower half cycle in reverse connection) (Figure 9G) represents the lower half cycle of the audio signal, and at this time the diaphragm 3 moves rearward while widening the interval between the folds (outside the cylindrical form). The air pressure in the folds decreases, and the backward movement further accelerates the descent. In other words, the air pressure drops twice. Similarly, it is a synergistic double action. Inside the cylindrical shape, the behavior is completely opposite. If the speaker connections are reversed, the operation will be in the upper half period of the audio signal.

以上をまとめるとヒダの間隔が広くなつたり狭
くなつたりする伸縮動作が同時に作用する前後運
動と矛盾なく相乗的に作用するのである。 To summarize the above, the expansion and contraction movements that widen and narrow the distance between the folds work synergistically without contradiction with the simultaneous back and forth movement.

こうして伸縮動作と前後運動との二重動作は極

ろうか？すなわち、同じマグネツトのギヤツプ幅

1.4倍となる。（第９図Ｉ） つまりマグネツトのギヤツプ幅よりも1.4倍の
振幅が得られる。これが二重動作のメリツトであ
る。 In this way, the dual motion of telescopic motion and back and forth motion becomes extremely efficient. How much more efficient will it be? That is, the amplitude is larger than the gap width of the same magnet. (Figure 9H) expresses this, and F1 of the back and forth movement and the expansion and contraction movement.
If F2 and F2 are perpendicular to each other and have the same magnitude, the total motion (amplitude) of F3 is root 2, that is, approximately
It becomes 1.4 times. (Fig. 9 I) In other words, an amplitude 1.4 times larger than the gap width of the magnet can be obtained. This is the advantage of dual operation.

こうして従来タイプの全面駆動型ダイナミツ
ク・スピーカーならマグネツトのギヤツプ幅でダ
イアフラム（振動膜）の振幅が、その大きさを制
限されたが、本発明ではそのギヤツプ幅の最大
1.4倍まで振幅が取れる。 In this way, in the conventional type of fully-driven dynamic speaker, the amplitude of the diaphragm (vibrating membrane) was limited by the gap width of the magnet, but with the present invention, the amplitude of the diaphragm (vibrating membrane) is limited by the gap width of the magnet.
Amplitude up to 1.4 times can be obtained.

高くなる。 In addition, both the front and rear surfaces and one of the side surfaces of the telescoping magnet 4 can be used for driving force, making it more economical to use. (In the conventional type, only the side surface where the magnet is located can be used for driving force.) Furthermore, since the cylindrical diaphragm 3 is formed into an accordion curtain shape, not only the apparent size is reduced, but also energy is converged and efficiency is increased.

来る様にセツトしたダイナミツクスピーカー。1 A cylindrical form with a space inside, such as a cylinder, long cylinder, or prism, with both sides of the space connected to the outside space, is composed of a group of small magnets that are rectangular, flat, and of the same shape and have the same magnetic force. The contents of the structure are such that the small magnets are arranged to face each other with the same polarity separated by a certain distance, and the direction of the magnetic poles of the whole magnet group is parallel to both openings to the outside of the cylindrical inner space. Furthermore, another small magnet is placed alternately on the inside and outside of the cylindrical form that these magnets constitute, and one for each magnet. Arrange the magnets with the same polarity facing each other with a distance between them, and group the cylindrical magnets thus created as a group.
Another group of magnets with exactly the same magnetic circuit and the same form as this one group is placed in the same direction and in series as the magnetic pole direction of the first group, and the positions of the individual magnets of both magnet groups are such that air can enter and exit. Arrange them together with a certain gap between them, insert non-magnetic rods or plates of a size that will not block air in and out in all the gaps, connect both groups of magnets, and then connect them. These magnets are made by forming a soft cylindrical diaphragm into an accordion curtain shape, which is printed on a conductor wire wound into a solenoid shape that becomes a voice coil after being stacked in several tiers. A dynamic magnet is inserted into the gap between the magnetic circuits where the same poles of the group face each other, and the conductor wire of the vibrating membrane is set in the gap between the stages of the stacked cylindrical magnet group. speaker.
