2. Description of the Related Art Elements constituting music are time signature, pitch, and melody, and effective music appreciation becomes possible when these three elements are fully felt. In conventional audio systems for listening to music,
I have focused on how effectively these three elements can be felt through hearing. However, since the time signature of these three elements is closely related to body movements such as dance, it can be said that it is an element of music that can be fully felt only by using a perceptual method at the same time as hearing.

Therefore, the inventor of the present application has used a “sensible speaker and a sensation system using the same” disclosed in Japanese Patent Application No. 1937 of 1992, which uses a sensation speaker capable of experiencing a beat by a magnetic vibration mechanism. , Proposed a sensation system that allows you to experience music lively. An object of the present invention is to improve the sensation speaker according to the present application and make it more effective.

[0004]

In order to achieve such an object, the sensation speaker according to the present invention has a casing having a storage space therein and a storage space of the casing which is projected and penetrates. An electromagnetic member that forms a magnetic field when energized in a cylinder hole that is formed in a state; and a vibrating body that is installed in the housing space of the casing and that vibrates due to the magnetic field formation of the electromagnetic member when energized. In the sensible speaker, the vibrating body includes a supporting member having an opening, a vibrating plate having the opening, a permanent magnet surrounding the through hole, and a flat plate-shaped armature having a plunger pillar projecting in the central portion. The vibration plate is fixed and supported by the casing around it, and is sandwiched between the permanent magnet and the supporting member. Further, the plunger pillar has a through hole for the permanent magnet and the vibration plate. Tips of the opening and the penetrated and plunger pillars of lifting members so as to combine the armature so as to face the cylinder bore of the electromagnetic member in the permanent magnet, is installed in a suspended state in the accommodating space of the casing,
Then, the auxiliary permanent magnet is made to face the cylinder hole of the electromagnetic member from the side opposite to the plunger pillar.

In the sensation type speaker thus constructed, the magnetic field of the electromagnetic member due to the energization acts on the magnetic field of the permanent magnet through the plunger column, so that the vibrating body vibrates and the entire casing vibrates. Now that it is directly transmitted, you can experience the beat of music. Furthermore, since the auxiliary permanent magnet facing the cylinder hole of the electromagnetic member from the side opposite to the plunger column acts to increase the amplitude of the vibrating body, the vibration is more easily transmitted.

At this time, the vibrating body of the sensible speaker is installed in a suspended state in the casing, and the side surface of the plunger column of the armature, the through hole of the permanent magnet, and the vibrating plate,
An electromagnetic member is inserted between each wall of the opening of the support member so that the electromagnetic member can reciprocate relative to the vibrating body. In addition, it is necessary to secure a space in which the vibrating body can be freely vibrated in the casing when the vibrating body vibrates due to a change in the magnetic field when a current flows through the electromagnetic member, with the vibrating body suspended in a space with a sufficient distance. is there.

[0007] In such a body-sensing speaker, if a further vibration plate is provided around the casing, which is fixed and supported by the casing and is sandwiched between the permanent magnet and the armature, the vibration body is more stably supported. At the same time, the vibration force becomes larger and the vibration is easily transmitted.

If the casing is formed by assembling a lid member made of a light metal such as aluminum on each side of a plastic frame member formed in a flat annular body, the casing is easy to assemble, and the casing is not distorted by heat. It can be prevented and is in good condition.

Further, when flange convex strips having a thickness similar to that of the permanent magnet are provided in a stepped manner on the inner wall of the frame member, and the peripheral edge portion of the diaphragm is supported by the flange convex strips, vibration occurs. It is preferable because the body can be easily positioned and installed. The outer shape of the frame member is not particularly limited as long as it has such an action, and may be appropriately designed in consideration of designability and the like.

The electromagnetic member is formed by winding a solenoid coil around a tubular member having a flange formed at one end and a short flange formed at the other end, and the electromagnetic member is provided on the lid member from the other end side. If the flange at the one end is fixed to the peripheral portion of the opening by inserting it into the storage space through the opening, the assembly is easy. Further, at this time, a step is formed around the opening provided in the lid member, and the flange at one end of the electromagnetic member is fixed to the step, and
The flange of the electromagnetic member is covered with a flange formed at the mouth of a plug member having a cup-shaped bottom portion that can be inserted into the cylinder hole of the electromagnetic member and having an auxiliary permanent magnet mounted on the cup-shaped bottom portion. By fixing to the step, it is possible to prevent dust and the like from entering the casing, and the auxiliary permanent magnet can act so as to increase the amplitude of the vibrating body. The auxiliary permanent magnet attached to the plug member may be a disk-shaped or ring-shaped auxiliary magnet, or may be a magnet provided with a large number of holes.

Further, since the solenoid coil is wound around a tubular member having a short flange formed at the other end to be inserted into the storage space, the electromagnetic member is used, so that the wound solenoid coil can be prevented from coming off. Has become.

Further, if an elastic body made of raw rubber or the like is attached to the inner wall surface of the lid member to assist in transmitting the vibration of the vibrating body, the sensation effect becomes more effective.

FIGS. 9 to 12 show an embodiment in which an audible speaker according to the present invention connected to an audio amplifier is incorporated in a seat, a vest, a belt and a mattress to form an audio system.

Various methods are conceivable for incorporating the sensible speaker according to the present invention into a seat or the like. As an example, there is a method of arranging sensation speakers appropriately in a mold, pouring polyurethane or the like, and integrally molding. However, at this time, it is necessary to cover the plug member with a non-woven fabric so that a melted material such as polyurethane does not enter the sensible speaker.

The operation of the audio system using such a sensation speaker is as follows. That is, when the acoustic signal output from the audio amplifier flows through the solenoid coil, the strength of the magnetic field of the solenoid coil changes depending on the strength of this signal. Then, the vibrating body vibrates due to the interaction between the magnetic field of the solenoid coil and the magnetic field of the permanent magnet. As a result, the entire casing including the vibrating body vibrates according to the acoustic signal, and this vibration is transmitted to the user's body such as the seat with the sensation speaker inside, and the user feels the beat of the music. Can be done. It should be noted that when the sensation speaker is placed in a waistcoat or a belt, it is more effective to arrange the sensation speaker on the wearer's back.

The sensation speaker according to the present invention is most effective especially when listening to music that clearly contains middle and low tones. This is because the vibrating body can vibrate most greatly with the acoustic signal of middle and low tones. Therefore, at the time of listening to music through the stereo sound system, it is possible to more effectively operate the sensible speaker by sending only the middle and low sound signals to the sensible speaker.
For this purpose, the output of the stereo sound system may be passed through a low pass filter so that, for example, only signals of 120 Hz or lower in the output are amplified and sent to the sensible speaker. .
There is a known crossover control as a method of separating only the middle and low tone signals.
