Description

  The present invention relates to an apparatus for adjusting the auditory sensitivity of a person or an animal, and more particularly, to an auditory sensitivity adjustment apparatus suitable for increasing concentration and attention in any direction.

  Humans perceive sound by collecting sounds from the outside world through the ear shell and transmitting them to the eardrum via the ear canal. It is known that a person's hearing affects concentration and attention, and that the concentration and attention of a person increases if the hearing sensitivity is increased by increasing the sound collection effect (Patent Document 1). A headphone-type sound collector that can efficiently collect a voice from the front is also known (Patent Document 2).

  However, in the technique described in Patent Document 1, since the sound from the front and its own voice are reflected by the side shielding plate and collected by the ear (the same document [0020]), the front Only sounds from and voices can be collected. In the technique described in Patent Document 2, since the sound from the front is reflected by the ear cover and collected by the ear (the same document [0009]), only the sound from the front is collected. Can not do it. For example, if the auditory sensitivity to the sound from the rear is increased, the concentration and attention to the rear increase. The same applies to the sound from the left, the sound from the right, the sound from above, the sound from below, and the sound from other directions. Since this technique enhances the sound collection effect for sound from a specific direction (forward, etc.), there is a problem that it is difficult to increase concentration and attention in any direction.

  Therefore, the present invention has been made paying attention to such unsolved problems of the conventional technology, and provides a hearing sensitivity adjustment device suitable for increasing concentration and attention in any direction. The purpose is to do.

  [Invention 1] In order to achieve the above object, an auditory sensitivity adjustment apparatus according to Invention 1 is an auditory sensitivity adjustment apparatus for adjusting an auditory sensitivity of a human or an animal, and holds an ear shell of a human or an animal. Means, an earshell pulling means for pulling the earshell gripped by the earshell gripping means in the extending direction, and an earshell operating means for twisting or swinging the earshell gripped by the earshell gripping means.

  With such a configuration, the ear shell is grasped by the ear shell grasping means, and the grasped ear shell is pulled in the extending direction by the ear shell pulling means. Also, the grasped earshell is twisted or rocked by the earshell operating means. That is, by moving the ear shell by the ear shell operating means, it is possible to increase the auditory sensitivity to sound from any direction. For example, in order to increase the auditory sensitivity to sound from the rear, the ear shell may be moved so that the surface of the ear shell faces rearward.

  Here, “adjusting auditory sensitivity” means adjusting the degree to which a person or animal perceives sound by moving the ear shell according to the present invention, and does not adjust the auditory function that a person or animal originally has. Absent.

  As described above, according to the auditory sensitivity adjustment apparatus of the first aspect, the auditory sensitivity with respect to sound from any direction can be increased by moving the ear shell by the ear shell operating means. Can increase concentration and attention in any direction.

  The housing 10 is configured by a member that easily transmits sound from the outside world. Alternatively, one or a plurality of small holes or windows may be formed in the housing 10 so that sound from the outside world can be transmitted.

  The cushion member 20 is made of an elastic member such as a cushion, and is formed in an annular shape along the bottom of the housing 10. The cushion member 20 is attached to the bottom of the housing 10 via a plurality of springs 22. The spring 22 applies a biasing force that pulls the ear shell 50 gripped by the ear shell gripping portion 30 in the extending direction.

  The ear shell gripping portion 30 includes a base body 38 and a pair of grab parts 32 a and 32 b that grip the ear shell 50.

  The grab part 32a is formed in an L shape in the extending direction, whereas the grab part 32b is formed in an inverted L shape in the extending direction symmetrical to the grab part 32a. The grab parts 32a and 32b are such that the end 34a of the grab part 32a faces the tip of the grab part 32b (the end on the side that holds the ear shell 50), and the end 34b of the grab part 32b is the end of the grab part 32a. They are combined so as to cross each other so as to face the tip (the end on the side that holds the ear shell 50). A spring 36 is provided between the inner side of the end 34a of the grab part 32a and the inner side of the end 34b of the grab part 32b. The spring 36 applies an urging force that brings the tips of the grab parts 32a and 32b closer to each other and an urging force that separates the ends 34a and 34b of the grab parts 32a and 32b.

  The grab parts 32 a and 32 b and the spring 36 are attached to the base 38, the end 34 a of the grab part 32 a protrudes from the side opening of the base 38, and the end 34 b of the grab part 32 b is the side opposite to the base 38. Projects from the opening. When the wearer presses the ends 34a and 34b of the grab parts 32a and 32b protruding from the base body 38, the tips of the grab parts 32a and 32b are opened, and the pressing of the ends 34a and 34b of the grab parts 32a and 32b is released. The tips of the grab parts 32 a and 32 b are closed by the biasing force of the spring 36.

  An opening is formed at the top of the housing 10. On the other hand, a cylindrical shaft member 40 having a slightly smaller diameter than the top opening of the housing 10 is formed at the bottom of the base body 38, and a flange having a larger diameter than the top opening of the housing 10 is formed at the tip of the shaft member 40. Is formed. The ear shell gripping portion 30 is attached to the housing 10 by fitting the shaft member 40 into the top opening of the housing 10. The ear shell gripping part 30 is locked by the flange of the shaft member 40 so as not to be detached from the housing 10 and can be rotated with respect to the housing 10 about the shaft member 40.

  The tip of the grab part 32a has a shape imitating a human thumb as shown in FIG. 3, and the tip of the grab part 32b is an index finger when the hand is gripped (the first to third joints are bent and the index finger is rolled up) It has a shape that mimics the state. The grab parts 32a and 32b urge the earshell 50 by the biasing force of the spring 36 so that the tip of the grab part 32a sandwiches the earshell 50 from the back side of the earshell 50 and the tip of the grab part 32b from the front side of the earshell 50, respectively. Hold it. Since the ear shell 50 is gripped between the thumb and the index finger gripped, it is possible to give the wearer the feeling of gripping with a human hand and to reduce the uncomfortable feeling of wearing. For these reasons, it is preferable that the tips of the grab parts 32a and 32b have elasticity equivalent to that of human fingers.

Next, the operation of the present embodiment will be described.
The wearer first presses the ends 34a and 34b of the grab parts 32a and 32b, and holds the hearing sensitivity adjustment apparatus 100 with the tips of the grab parts 32a and 32b open. Next, the auditory sensitivity adjustment device 100 is mounted so that the cushion member 20 faces the ear shell 50 and covers the ear shell 50. At this time, the auditory sensitivity adjustment device 100 is mounted so that the ear shell 50 is positioned between the tip of the grab part 32a and the tip of the grab part 32b. When the pressing of the ends 34a, 34b of the grab parts 32a, 32b is released, the tips of the grab parts 32a, 32b are closed by the biasing force of the spring 36, and the ear shell 50 is gripped by the grab parts 32a, 32b. The spring 22 is pulled in the extending direction by the urging force of the spring 22.

  For example, in order to increase the hearing sensitivity with respect to the sound from above, the ear shell gripping portion 30 may be rotated counterclockwise. When the ear shell gripping portion 30 is rotated counterclockwise, the ear shell 50 gripped by the grab parts 32a and 32b is twisted counterclockwise and the surface of the ear shell 50 faces slightly upward. Hearing sensitivity to sounds from above increases.

  Further, for example, in order to increase the auditory sensitivity to the sound from below, the ear shell gripping part 30 may be rotated clockwise. When the ear shell gripping portion 30 is rotated clockwise, the ear shell 50 gripped by the grab parts 32a and 32b is twisted clockwise, and the surface of the ear shell 50 faces slightly downward.
