DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a method of the acoustic vibrational bodily sensation for imparting vibrations (in this invention, referred to as "imparting bodily sensation") obtained by an electric machine vibration converter in response to an electric signal having an acoustic frequency, as responsive effect to the human body through the skin, a bone or the like without the auditory sense, and an apparatus therefor. Particularly, this invention provides a configuration in which vibrations are transmitted to a fingertip which is sensitive in feeling to thereby increase the bodily sensation to be imparted.
BACKGROUND ART
The conventional method for imparting the acoustic vibrational bodily sensation and apparatus therefor as described above has its main object that while enjoying the music with the auditory sense, rhythmic sense caused by the music is tasted with the bodily sensation to thereby further increase the pleasant sensation caused by the music. A further object thereof is to let a deaf and dumb person learn an intonation in conversational utterance.
Further, the electric machine vibration converter 100 includes a speaker of the voice coil type as shown in FIG. 8 (hereinafter referred to as the first prior art) and disclosed in Japanese Utility Model Laid-Open Publication No. 75430/1977, and or a solenoid actuator type as shown in FIG. 9 (hereinafter referred to as the second prior art) and disclosed in Japanese Utility Model Laid-Open Publication No. 171371/1982.
In FIG. 8, a cylindrical movable coil 51 is arranged to be freely moved in and out of a gap 54 whose section is in the form of a slot and whose plane is annularly provided within a field system 53 magnetized by a permanent magnet 52. A vibrator 55 secured to the movable coil 51 is held on the side of the field system 53 through an elastic holding plate 56. With this configuration, an electric signal having an acoustic frequency is applied to the movable coil 51 so that the movable coil 51 may be mechanically vibrated in response to the frequency and amplitude of the electric signal and a vibration source is obtained from relative vibrations between the field system 53 and the vibrator 55.
The constitution shown in FIG. 8 is called the speaker voice coil type since the mode of arrangement of the movable coil 51 and the field system 53 corresponds to that of a voice coil in a speaker and a field yoke.
In FIG. 9, an exciting coil 61 is embedded into a field system 62, and an elastic vibrator 63 is arranged opposite to the side of a release end of the field system 62 and held on the side of the field system 62 through an elastic holding plate 64. With this configuration, an electric signal having an acoustic frequency is applied to the exciting coil 61 so that the vibrator 63 may be mechanically vibrated in response to the frequency and amplitude of the electric signal and a vibration source is obtained from relative vibrations between the field system 62 and the vibrator 63.
As the an agrangement; and in which the movable side and the fixed side in the constitution shown in FIG. 9 are reversed, Japanese Patent Laid-Open Publication No. 14996/1993 discloses a device (hereinafter referred to as the third prior art) in which the vibrator 63 as a permanent magnet is arranged on the fixed side, and the exciting coil 61 and a magnetic core for a field 62 are held by the elastic holding plate and arranged on the movable side.
The constitution shown in FIG. 9 is called the solenoid actuator type since the arrangement is one in which the vibrator is attracted and deenergized by the magnetic force produced by the exciting coil 61 and the field system corresponds to that of a solenoid field system and an actuator in the solenoid actuator.
On the other hand, as the an arrangement for imparting the bodily sensation, there is proposed a constitution (hereinafter referred to as the fourth prior art) in which a contact portion provided in the vibrator 63 is laid on a body bone portion --;--; such as an ear bone --;--, to impart the bodily se
