FIG. 1 is a perspective view illustrating a sound collecting device according to a first embodiment of the present invention, FIG. 2 is a perspective view for explaining a putting part of a sound collecting device according to the first embodiment of the present invention, FIG.

1 to 3, the sound collecting apparatus according to the first embodiment of the present invention includes a sound collecting unit 110 and a wearing unit 120.

The sound collecting unit 110 is a part where sound is collected. The sound collecting unit 110 includes a first plate 111. The first plate 111 is made of a flexible material. For example, the first plate 111 may be made of a chemical plastic such as polypropylene or polyethylene, an engineered plastic composite, or a flexible thin plate-like metal plate. Also, the inner surface of the first plate 111 may have a smooth surface to avoid diffused reflection of sound waves and to cause total reflection. Since the sound collecting unit 110 is made of a flexible material, it can be bent at a predetermined curvature, and the bent first plate 111 is positioned around the ear and the ear of the user, do. The bent shape of the first plate 111 may be, for example, a tubular shape having a semicircular cross section, or a conical shape. The inner surface of the first plate 111 bent in such a shape forms a curved surface (parabolic surface).

The wearer 120 allows the first plate 111 to be worn by the user. The wearing portion 120 is installed on one surface of the first plate 111. For example, the wearing portion 120 may be a wear ring 121 that can be fingered. The wear ring 121 may be made of, for example, rubber and is not particularly limited thereto.

The wearing portion 120 may be fixed to the first plate 111 or may be detachable. When the wearing portion 120 is fixed to the first plate 111, for example, the wear ring can be fixed with an adhesive. When the wearing portion 120 can be detachably attached to the first plate 111, for example, the velcro tapes 122a and 122b can be used. At this time, the wear ring 121 can be fixed to the back surface of the attachment surface of the male type Velcro tape 122a (or the female type Velcro tape) by an adhesive or sewing. In this case, a female type Velcro tape 122b (or a male type Velcro tape) is fixed to one surface of the first plate 111, and the wear type ring 121 is detached and attached by detachment of the female type Velcro tape and the male type Velcro tape.

When the Velcro tape is used to attach and detach the wearing part 120 to the first plate 111 as described above, the male type Velcro tapes 122a and 122b to which the wear ring 121 is fixed are formed to have a small area And the female type Velcro tape 122b fixed to the first plate 111 can be formed to have a larger area than the male type Velcro tape 122a. In such a case, the position where the male type Velcro tape 122a to which the wear ring 121 is fixed may be attached to the female type Velcro tape 122b. For example, the male type Velcro tape 122a may be attached so as to be positioned at the center of the female type Velcro tape 122b or positioned to the left or right of the center of the female type Velcro tape 122b. If the attachment position of the male type Velcro tape 122a is different, the wear ring 121 can be positioned according to the size of the user's hand.

The engaging portion 112a moves along the extending direction of the slit 111a so that the second plate 112 (the engaging portion 112a) Is moved on the first plate 111 while being coupled to the first plate 111. As a result, the length of the sound collecting unit 110 is increased. The length of the sound collecting unit 110 is shortened if the second plate 112 is pushed toward the first plate 111. [ The length of the sound collecting unit 110 is varied by the movement of the second plate 112. Here, the inner surface of the second plate 112 may have a smooth surface to avoid diffused reflection of sound waves and to cause total reflection.

Hereinafter, a process of collecting sound around a user using the sound collecting apparatus 100 according to the first embodiment of the present invention will be described. FIG. 4 is a perspective view showing a state where the first plate and the second plate shown in FIG. 1 are bent into a tube shape, FIG. 5 is a view showing a state where the first plate and the second plate bent as shown in FIG. Fig. 6 is a perspective view showing a state in which the second plate shown in Fig. 4 is drawn out from the first plate. Fig.

In order to use the sound collecting apparatus 100, first, the user's finger is inserted into the wear ring 121 so that the first plate 111 and the second plate 112 are fixed on the user's hand. In such a state, when the user wishes to collect sounds around the user, the user may bend the fingers and the palm of the hand so that the first plate 111 and the second plate 112 are in a tubular shape having a semicircular cross section as shown in FIG. 4 . At this time, the curvature at which the first plate 111 and the second plate 112 are bent is adjusted according to the degree of bending of the user's finger and palm. Next, the user's ears are inserted through the non-abutting ends of the first plate 111 bent in a tubular shape having a semicircular cross section. At this time, the end side of the first plate 111 corresponding to the ear of the user completely surrounds the circumference of the user's ear. The user's ears are located in an inner space formed by bending the first plate 111 and the second plate 112 and the first plate 111 and the second plate 112 are located in the vicinity of the user & . This state is shown in Fig.

In this way, when the sound collecting apparatus 100 is wrapped around the user's ears and the ear, the sound (sound) around the user is gathered by the sound collection formed by bending the first plate 111 and the second plate 112 in the form of a tube And is collected into the inner space of the portion 110. At this time, the wavelengths of the collected sound are reflected after the first plate 111 and the second plate 112 bend against the formed curved surface and proceed toward the user's ear. Through this process, the wavelengths of sound are concentrated in the innermost regions of the first plate 111 and the second plate 112 where the ears of the user are located, whereby the first plate 111 and the second plate 112, The volume (volume) of the sound introduced into the inner side of the speaker is amplified. Therefore, the user can hear the surrounding sound largely.

Meanwhile, in the process of collecting sounds, the user can move the second plate 112 in a direction away from the first plate 111 to lengthen the length of the sound collecting unit 110, and then collect the sound around the second plate 112. This state is shown in Fig. In this case, since the sound collecting unit 110 has a long length, the sound around the user reaches the inner space of the sound collecting unit 110 more quickly than when the sound collecting unit 110 has a short length. Thereby, the sound around the user can be collected and amplified more quickly, so that the user can hear the sound around the user. In addition, when the sound collecting unit 110 has a long length, it is possible to listen to the sound generated at a remote place of the user and to hear the transmitted sound, as compared with the case where the sound collecting unit 110 has a short length.

In the process of collecting sound around the user through the above process, the sound collecting apparatus 100 wraps around the user's ear and the ear but is not in a fixed form. When the user presses the first plate 111 and the second plate 112 are bent in the form of a tube having a semicircular cross section to wrap around the user's ears and the ear so that the user can freely change the direction of the sound collecting device 100 regardless of the direction in which the sound to be collected is generated Sound collection is possible.

Thus, the process of collecting the sound around the user can be performed without regard to time and place. That is, the user can use it whenever he / she wants to hear the surrounding sound louder. In particular, the process of collecting sound around such a user may be beneficial in places such as, for example, a sports arena, a theater or the like.

In the case of a sports arena, there is a mixture of various noises and a lot of people are crowded, so that the voice of a neighboring person can be transmitted well when used in a conversation process with a neighbor in a sports arena. Also, it can be used in case of collecting and listening to the sports relay sound in the sports arena.

In the case of a performance hall, the audience of the performer who is located far away from the performer and collecting the metabolism will be greatly heard.

Since the sound collecting apparatus 100 according to the first embodiment of the present invention is easy to use and is formed in a plate shape, it is convenient to carry, and the convenience of use such as the ability to collect near and far sounds by varying the length Increase.
