Description

[Technical field]

[0001] The present invention relates to a speaker device and a hood-type speaker device. [Background technology]

[0002] Wearable speakers such as head speakers and ear speakers that can be installed near the left and right ears have been proposed. For example, Patent Document 1 discloses an ear speaker that includes a speaker and a mounting part that mounts the speaker at a position a predetermined distance away from the listener's ear holes, and that is movably attached to the mounting part so that the speaker is directed toward the listener's ear holes when the ear speaker is mounted on the listener. This ear speaker can prevent headphone-induced hearing loss, and because it does not block the ears, it allows the listener to hear surrounding sounds and enjoy audio playback safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment for carrying out the present invention will be described. The hood-type speaker device 1 shown in Fig. 1 and Fig. 2 includes a speaker device 2 built into a hood 3, and can be used by wearing the hood 3 over the head H1. The hood 3 of this embodiment has a three-layered fabric consisting of an outer fabric 31, an inner lining 32, and an inner lining 33. The hood 3 shown in Fig. 1 and Fig. 2 shows the positions of the outer fabric 31, the inner lining 32, and the inner lining 33. The hood 3 may be provided integrally with or detachably attached to clothing such as a jacket, or may be formed as a separate unit.

[0011] The speaker device 2 is disposed between the inner lining 32 and the inner lining 33 (see also FIG. 2). The speaker device 2 is mainly fixed to the inner lining 32. The entire lining 33 or the peripheral portion where the speaker 6 is disposed is configured to allow easy sound transmission, for example, by forming it in a mesh shape or by providing an opening. A sound absorbing material can be disposed between the outer lining 31 and the inner lining 32 to reduce sound leakage to the outside of the hood 3. The hood-type speaker device 1 can be worn such that the left speaker 6a and the right speaker 6b are spaced apart from the left and right ears H2. Therefore, the user can hear the sounds emitted from the left speaker 6a and the right speaker 6b with stable acoustic characteristics without feeling any pressure on the ears H2.

[0012] In the following description of the hood type speaker device 1 (including the speaker device 2), the front side as seen by a user wearing the hood type speaker device 1 in Fig. 1 is referred to as the front, the opposite side as the rear, and the upper side as seen by the user in Fig. 1 is referred to as the top, and the opposite side as the bottom. Also, the left side of the hood type speaker device 1 as seen by the user in Fig. 1 is referred to as the left, and the opposite side as the right.

[0013] Next, the speaker device 2 will be described in detail. FIG. 3 is a perspective view of the speaker device 2 as seen from the rear side. The speaker device 2 is formed in a substantially U-shape as a whole. The speaker device 2 includes a main body 4 in the form of a long rectangular thick plate, left and right frames 5 (left frame 5a and right frame 5b) rotatably connected to the main body 4, left and right speakers 6 (left speaker 6a and right speaker 6b) rotatably connected to the left and right frames 5, and left and right support parts 7 (left support part 7a and right support part 7b) rotatably connected to the left and right frames 5. The frame 5 includes a left frame 5a connected to the left speaker 6a and the left support part 7a, and a right frame 5b connected to the right speaker 6b and the right support part 7b. The left frame 5a and the right frame 5b are configured to be openable and closable via a hinge part 41 (see also FIG. 9(a), FIG. 9(b), and FIG. 10). The speaker 6 and the support portion 7 are connected to the frame 5 so as to be rotatable about two axes (a roll axis (first axis P1, third axis P3) and a yaw axis (second axis P2, fourth axis P4) described below).

[0014] Next, the configuration of the right arm section 22 (including the right frame 5b, the right speaker 6b, and the right support section 7b) side of the speaker device 2 will be described with reference to Figs. 4 to 8. The left frame 5a and the left support section 7a of the left arm section 21 are configured symmetrically with respect to the right frame 5b and the right support section 7b of the right arm section 22, respectively, and have similar functions. The left speaker 6a is configured to have an outer shape that is approximately symmetrical with respect to the right speaker 6b, but differs in the configuration of a push button SW and the presence or absence of a jack J, which will be described later. The same components of the left arm section 21 as those on the right arm section 22 side are denoted by the same reference numerals, and their description will be omitted or simplified.

[0015] The main body 4 includes a battery, a control circuit, and the like therein. On both the left and right sides of the main body 4, shaft members 41a are provided with an axis extending in the vertical direction. The frame 5 is connected to the main body 4 so as to be rotatable around the shaft member 41a by inserting the shaft member 41a into the shaft hole of the bearing portion 51 (see also FIG. 9(a)). The main body 4 has a cylindrical rod-shaped engaged portion 41b arranged in the vertical direction on the inside of the main body 4 (inside the speaker device 2) of the shaft member 41a (see FIGS. 4 and 9(a)). The frame 5 has a cylindrical rod-shaped engaged portion 51a arranged in the vertical direction on the outside of the shaft member 41a (see FIGS. 5 and 9(a)). The bearing portion 51 of the frame 5 has an outer diameter formed in a cylindrical shape, and a groove portion 511 extending in the circumferential direction is provided on the outer surface on the front side.

[0016] Furthermore, a U-shaped curved leaf spring elastic member 42 is attached to the hinge portion 41 and the bearing portion 51 (see Figs. 4 and 9(a)). Engagement portions 421 that are further curved in directions facing each other are provided at both ends of the elastic member 42. The elastic member 42 is attached in a tensioned state with the engagement portions 421 engaged with the engaged portions 41b and 51a. When the frame 5 is in the open state, the center side of the elastic member 42 is disposed within the groove portion 511 (see Fig. 9(a)), and interference with the bearing portion 51 is avoided.

[0017] The left frame 5a and the right frame 5b are formed long so as to spread outwardly and obliquely upward from the main body 4 in the open state (see also Figs. 1 and 2). As shown in Fig. 4, the inside of the frame 5 is open in the longitudinal direction. A flat sliding surface 52 is provided at the end of the frame 5 opposite the main body 4. This sliding surface 52 is provided with an opening 521 that opens substantially in the longitudinal direction in Fig. 4, and a rectangular prism-shaped restricting protrusion 522 that protrudes from the sliding surface 52 in the normal direction below the opening 521.

[0018] The support portion 7 has a base side rotating member 71 rotatably connected to the frame 5 within a predetermined angular range, and a tip side member 72 rotatably connected to the base side rotating member 71 within a predetermined angular range, and is formed in a substantially L-shape extending from the rear to the upper side of the speakers 6 (left speaker 6a and right speaker 6b). The base side rotating member 71 has a supported portion 711 including an opening 711a supported by a screw member 53 at the center. The supported portion 711 has flat sliding surfaces 711b, 711c (see also FIG. 5) with the axis of the opening 711a facing the front-rear direction. The supported portion 711 has a rectangular prism-shaped restricted portion 712 extending in one direction perpendicular to the axis of the opening 711a. Further, the supported portion 711 has a substantially cylindrical extending portion 713 extending in the other direction perpendicular to the axis of the opening 711a, on the opposite side to the regulated portion 712. The extending portion 713 and the regulated portion 712 are arranged on opposite sides of the supported portion 711 in a substantially parallel direction.

[0019] The extended portion 713 on the side of the supported portion 711 is cut out in an L-shape in cross section, and a restricting portion 714 is provided for restricting the base side rotating member 61 of the speaker 6 within a predetermined rotation range. An inner contact surface 714a of the restricting portion 714 and a sliding surface 711b are disposed at a substantially right angle. In addition, in the state of FIG. 4 in which the restricted portion 712 is disposed downward and the extended portion 713 is disposed upward, the contact surface 714a is disposed facing the inside of the speaker device 2 and is disposed outside the opening 711a (on the right side in the case of the right support portion 7b).

[0020] As shown in the enlarged view of part A in FIG. 4, a cylindrical shaft portion 715 having a smaller diameter than the outer shape of the extension portion 713 and approximately coaxial with the extension portion 713 protrudes from the tip of the extension portion 713. A female screw portion 715a is formed approximately at the center of the tip side of the shaft portion 715. The extension portion 713 also has an outer circumferential portion 715b, which is a C-shaped flat surface, around the shaft portion 715, and a rotation restricting portion 715c protruding toward the shaft portion 715 from the outer circumferential portion 715b. The outer circumferential portion 715b is provided in an angular range of 270 degrees around the shaft portion 715, and the rotation restricting portion 715c is provided in an angular range of 90 degrees. The height of the rotation restricting portion 715c is formed lower than the shaft portion 715.

[0021] As shown in the enlarged view of part B in FIG. 5, the tip side member 72 is provided in a substantially cylindrical shape with the connection side with the base side rotating member 71 curved in a substantially 90-degree arc shape. A circular recess 721 is provided on the inside of one end side of the tip side member 72. The recess 721 has a screw hole 721a through which a screw member (not shown) can be inserted. The tip side member 72 has an outer peripheral portion 721b, which is a semicircular flat surface, around the outer peripheral edge of the recess 721, and a rotation-restricted portion 721c protruding from the outer peripheral portion 721b in the axial direction of the screw hole 721a. The outer peripheral portion 721b and the rotation-restricted portion 721c are each provided within an angular range of 180 degrees around the axis of the screw hole 721a. Since the tip side member 72 is curved, the screw hole 721a penetrates the curved side surface on the convex side of the tip side member 72. A recess 722 in which the head of a screw member can be placed is provided on the side of the screw hole 721a opposite the recess 721 (see also FIG. 7). Therefore, the tip side member 72 and the base side rotating member 71 are connected to be rotatable within a predetermined angle range by fastening a screw member inserted from the recess 722 side to the female screw portion 715a via the screw hole 721a.

[0022] The tip side member 72 has an opening 723 to which the hanging member 8 (see FIG. 1, etc.) is connected on the side opposite to the rotation restricted portion 721c. The opening 723 is formed long in the axial direction of the tip side member 72, penetrating in the left-right direction of FIG. 4. As shown in FIG. 1, the mounting part 70 connected to the left and right positions of the frame 5 by the left support part 7a, the right support part 7b, and the hanging member 8 is configured to be capable of being suspended from the head H1, so that the speaker device 2 (or the hood-type speaker device 1 including the hood 3) can be easily mounted on the head H1 by the mounting part 70.

[0023] The hanging member 8 includes a hanging cord 81, which is a string-like body, a lower adjuster 82, and an upper adjuster 83. The hanging cord 81 is inserted through the opening 723. One end of the hanging cord 81 is connected to the left support part 7a above the left speaker 6a. The other end of the hanging cord 81 is connected to the right support part 7b above the right speaker 6b. Therefore, the hanging cord 81 is disposed between the left support part 7a and the right support part 7b. The lower adjuster 82 can be fixed at any position relative to the hanging cord 81 while the hanging cord 81 is inserted through it. The lower adjuster 82 is formed to be larger than the opening 723. Therefore, when the hanging cord 81 located between the left support part 7a and the right support part 7b is pulled (in the example of FIG. 1, when the speaker device 2 is hung from the head H1 by the hanging cord 81), the lower adjuster 82 comes into contact with the opening edge of the opening 723 as shown in FIG. 1, and the amount of the hanging cord 81 pulled out between the left support part 7a and the right support part 7b is restricted. Therefore, the length of the hanging cord 81 between the left support part 7a and the right support part 7b can be adjusted by the fixed position of the lower adjuster 82, and this makes it possible to easily set the height (vertical position) of the speaker device 2 with respect to the head H1. In addition, the hanging cord 81 between the left support part 7a and the right support part 7b is divided into two. Of these, the front hanging cord 81 is suspended in front of the head H1, and the rear hanging cord 81 is suspended behind the head H1, so that the speaker device 2 is supported so as not to slip off (see also FIG. 2). The length of the hanging cord 81 divided into two can be adjusted by the upper adjuster 83.

[0024] Returning to FIG. 4, the speaker 6 has a base side rotating member 61 and a speaker body 62. The base side rotating member 61 has a cylindrical support part 611 having a bearing 611a on the inside, and a cylindrical supported part 612 provided with a female screw part 612a (see also FIG. 5) that is approximately perpendicular to the bearing 611a with respect to the support part 611. The supported part 612 is connected to the support part 611 so as to extend laterally at approximately the middle part in the axial direction. The base side rotating member 61 has a rectangular thick plate-shaped restricted part 613 and a restricting part 614. The restricted part 613 is arranged so as to connect the curved side surfaces of the support part 611 and the supported part 612 to each other on one side of the bearing 611a. Moreover, the restricting part 614 is arranged so as to connect the curved side surfaces of the support part 611 and the supported part 612 to each other on the other side of the bearing 611a. The restricting portion 614 and the restricted portion 613 are provided substantially parallel to each other and extend in opposite directions.

[0025] The supported portion 612 has a flat sliding surface 612b on the rear side with the axis of the female screw portion 612a facing rearward in FIG. 5. The sliding surface 612b is provided on the same plane across the restricted portion 613 and the restricting portion 614. The restricted portion 613 is provided with an abutment surface 613a that abuts against the restricting protrusion 522 of the frame 5 to restrict the rotation of the base side rotating member 61. The restricting portion 614 is provided with an abutment surface 614a that abuts against the abutment surface 714a of the base side rotating member 71 to restrict the relative rotation of the base side rotating member 71 and the base side rotating member 61. In the state of FIG. 5 where the restricted portion 613 is located below the supporting portion 611, the abutment surface 613a and the abutment surface 614a are arranged on the outer surface of the speaker device 2 (on the right side in the case of the right speaker 6b). The base side rotating member 61 is configured to be axially symmetrical about the female screw portion 612a.

[0026] As shown in FIG. 4, the speaker body 62 is formed in a generally rectangular plate shape. On the inner surface of the speaker body 62, a sound emitting section 621 including a plurality of holes for emitting sound from the sound emitting element inside is provided. The sound emitting section 621 is surrounded by a rectangular rib 622 standing from the outer periphery. Also, on the outer surface of the speaker body 62, a sound emitting section 623 including a plurality of holes for emitting sound from the sound emitting element is provided (see the left speaker 6a in FIG. 3). On the outer periphery in front and behind the sound emitting section 623, ribs 624 extending up and down are provided. The sound emitting section 621 and the sound emitting section 623 are provided in a rectangular region. A cushion member may be arranged around the outer periphery of the rib 622.

[0027] A notch 625 is provided at the upper end of the speaker body 62 to avoid interference with the support part 7. Push button SW for operating the speaker device 2 can be arranged on the front edge and upper edge of the speaker body 62 (see also Figs. 1 and 2). As shown in Fig. 2, a connection part (jack J) to which a communication cable or the like can be connected is arranged on the outer side surface of the speaker body 62 of the left speaker 6a. The left speaker 6a, the right speaker 6b and the internal circuits of the main body part 4 are connected to each other by wiring (not shown).

[0028] Returning to Fig. 4, hinge portion 626 is provided to protrude from the inner surface of the end portion on the frame 5 side (rear side) of speaker body 62. Hinge portion 626 is provided in two places so that bearings 626a formed in the vertical direction in Fig. 4 are arranged in coaxial positions.

[0029] Next, the configuration of the connection state of each member will be described. As shown in the VI-VI cross-sectional view of Fig. 6, the screw member 53 inserted through the opening 711a of the base side rotation member 71 of the support portion 7 constituting the mounting portion 70 and the opening 521 of the frame 5 is fastened to the female screw portion 612a of the base side rotation member 61 of the speaker 6. As a result, the speakers 6 (left speaker 6a and right speaker 6b) are each connected to the frame 5 so as to be rotatable around the first axis P1. In addition, the support portions 7 (left support portion 7a and right support portion 7b) are each connected to the frame 5 so as to be rotatable around a third axis P3 that is parallel to and coaxial with the first axis P1.

[0030] 6, the base side rotating member 71 is clamped in the axial (first axis P1 and third axis P3) directions by the base side rotating member 61 and the frame 5, with the sliding surface 612b and the sliding surface 711b abutting against each other and the sliding surface 711c and the sliding surface 52 abutting against each other by fastening the screw member 53. Therefore, the speaker 6 (left speaker 6a, right speaker 6b) and the support part 7 (left support part 7a and right support part 7b) are connected to the frame 5 so as to be independently angle-adjustable (i.e., capable of being stationary at any angle) about the first axis P1 or the third axis P3.

[0031] Further, a shaft core member 63 is disposed in the bearing 611a of the base side rotating member 61 of the speaker 6 and the bearing 626a of the speaker main body 62. This allows the speaker main body 62 to be connected to the base side rotating member 61 so as to be rotatable around the second axis P2. In the connected state of Fig. 6, the base side rotating member 61 is disposed so that the upper and lower surfaces of the support portion 611 and the hinge portion 626 are in sliding contact with each other. Therefore, the speakers 6 (left speaker 6a, right speaker 6b) are connected to the frame 5 via the base side rotating member 61 so as to be angle adjustable (i.e., capable of being stationary at any angle) around the second axis P2.

[0032] 7, the base side rotating member 61 is restricted from rotating inward of the speaker device 2 (in the right arm 22, clockwise around the axes P1 and P3 as viewed from the front side of FIG. 7) by the restricted portion 613 (contact surface 613a) coming into contact with the inner surface 522a of the restricting protrusion 522. Also, the base side rotating member 61 is restricted from rotating outward of the speaker device 2 (in the right arm 22, counterclockwise around the axes P1 and P3 as viewed from the front side of FIG. 7) by the restricting portion 614 coming into contact with the upper surface 522b of the restricting protrusion 522.

[0033] Since the base side rotating member 61 and the speaker main body 62 are fixed around the first axis P1 (or the third axis P3), the entire speaker 6 is configured to be rotatable around the first axis P1 (or the third axis P3) within a predetermined angular range relative to the frame 5.

[0034] The first axis P1 is configured as a roll axis extending substantially in the front-rear direction, and the second axis P2 is configured as a yaw axis extending substantially in the up-down direction perpendicular to the first axis P1.

[0035] On the other hand, the base side rotating member 71 is also restricted from rotating inward of the speaker device 2 (in the right arm 22, clockwise around the axes P1, P3 as viewed from the front side of FIG. 7) by the restricted portion 712 abutting against the inner surface 522a of the restricting protrusion 522. The base side rotating member 71 is also restricted from rotating outward of the speaker device 2 (in the right arm 22, counterclockwise around the axes P1, P3 as viewed from the front side of FIG. 7) by the abutting surface 711d of the restricted portion 712 abutting against the upper surface 522b of the restricting protrusion 522. The base side rotating member 71 and the tip side member 72 are in sliding contact with each other with an appropriate load by a screw member (not shown) fastened to the female screw portion 751a, and are connected to each other so that the angle can be adjusted (i.e., they can be stopped at any angle).

[0036] Since the base side rotating member 71 and the tip side member 72 are fixed around the third axis P3 (or the first axis P1), the entire support portion 7 is configured to be rotatable around the third axis P3 (or the first axis P1) within a predetermined angular range relative to the frame 5.

[0037] In addition, when the abutment surface 614a of the restricting portion 614 abuts against the abutment surface 714a of the restricting portion 714, the base side rotating member 61 is restricted from rotating in the counterclockwise direction around the axes P1 and P3 as viewed from the front side of FIG. 7 (in other words, the clockwise rotation of the base side rotating member 71 is restricted around the axes P1 and P3). Therefore, as shown in the front view of FIG. 1, the rotation of the support portion 7 (left support portion 7a and right support portion 7b) is restricted so as not to approach the left and right ears H2 side more closely than the speakers 6 (left speaker 6a and right speaker 6b). Therefore, the left speaker 6a and the right speaker 6b can be connected to the frame 5 and held at a predetermined interval from each other, and can be maintained in a state of being spaced apart from the ears H2 (or head H1) at any distance.

[0038] 8, the tip side member 72 is connected to the base side rotating member 71 so as to be rotatable around the fourth axis P4 within a predetermined angular range. When the base side rotating member 71 and the tip side member 72 are connected, the rotation restricted portion 721c which is a protrusion on the tip side member 72 side is disposed on the outer periphery 715b on the base side rotating member 71 side. Also, the rotation restricting portion 715c which is a protrusion on the base side rotating member 71 side is disposed on the outer periphery 721b on the tip side member 72 side (see the enlarged view of part B in FIG. 5). As described above, the rotation restricting portion 715c is provided within an angular range of 90 degrees, and the rotation restricted portion 721c is provided within an angular range of 180 degrees. Therefore, the tip side member 72 is provided rotatable within an angular range of 90 degrees with the side surface of the rotation restricted portion 721c in the direction around the fourth axis P4 abutting against the side surface of the rotation restricting portion 715c around the fourth axis P4.

[0039] 8, the tip side member 72 is located at the rotation end in the counterclockwise direction as viewed from above the fourth axis P4, with the rotation restricted portion 721c and the rotation restricting portion 715c abutting against each other. The fourth axis P4 is disposed parallel to the second axis P2 in a state in which the restricted portions 613, 712 shown in FIGS. 7 and 8 etc. abut against the restricting protrusion 522. Therefore, the third axis P3 is configured as a roll axis extending substantially in the front-rear direction, and the fourth axis P4 is configured as a yaw axis extending substantially in the up-down direction perpendicular to the third axis P3.

[0040] In this way, the speaker 6 and the support portion 7 are connected to the frame 5 so as to be rotatable independently while being restricted within a predetermined angular range. The speaker 6 and the support portions 7 are also connected to each other so as to be rotatable independently while being restricted within a predetermined angular range. The left speaker 6a and the right speaker 6b are connected to the frame 5 so as to be rotatable around a first axis P1 and a second axis P2, respectively, and the left support portion 7a and the right support portion 7b are connected to the frame 5 so as to be rotatable around a third axis P3 and a fourth axis P4, respectively.

[0041] As shown in FIG. 1, when the speaker device 2 is attached so that the hanging cord 81 is placed on the head H1, the hanging cord 81 pulls the support part 7 toward the head H1. However, the rotation of the support part 7 around the third axis P3 (or the first axis P1) is restricted by the contact between the restricted part 712 and the restricting protrusion 522 or the contact between the restricting part 714 and the restricting part 614, and the rotation of the support part 7 around the fourth axis P4 is restricted by the contact between the rotation restricted part 721c and the rotation restricting part 715c. The angular position of the support part 7 around the first axis P1 (or the third axis P3) is also prevented from moving inward (to the head H1 side) from the speaker 6. Therefore, it is possible to prevent the tip side member 72 of the support part 7 from coming into contact with the head H1 or the ear H2.

[0042] Next, the hinge structure of the main body 4 and the frame 5 will be described. As shown in FIG. 9(a), as described above, the engaging portions 421 of the elastic member 42 engage with the engaged portions 41b and 51a. The elastic member 42 is arranged in a tensioned state against the elastic force. As shown on the left frame 5a side in FIG. 9(a), when the frame 5 opens and closes, the engaged portion 51a moves around the shaft member 41a as shown by the dashed line. When the frame 5 is in the open state, the engaged portion 51a is located at position Q1, and when the frame 5 is in the closed state, the engaged portion 51a is located at position Q3. Position Q2 is the position of the engaged portion 51a during the transition between the open state and the closed state of the frame 5, and indicates a state in which the engaged portion 41b and the engaged portion 51a are aligned in a straight line with the shaft member 41a in between. When engaged portion 51a is located at position Q2, the distance between engaged portion 41b and engaged portion 51a becomes longer than when engaged portion 51a is located at positions Q1 and Q3, and elastic member 42 is pulled further, increasing the elastic force of elastic member 42. Therefore, frame 5 is biased toward the open state where engaged portion 51a is located at position Q1 or the closed state where engaged portion 51a is located at position Q3, with position Q2 as the boundary, so that speaker device 2 can stably maintain its posture in either the open state (see Figs. 3 and 9(a)) or the closed state (see Figs. 10 and 9(b)).

[0043] As shown in FIG. 10, when the frame 5 (or the left arm portion 21 and the right arm portion 22) of the speaker device 2 is in a closed state, the speaker 6 and the support portion 7 can be rotated outwardly around the second axis P2 or the fourth axis P4, so that the tip of the speaker 6 faces forward and can be folded neatly and compactly.

[0044] The left speaker 6a and the right speaker 6b are connected to the frame 5 so as to be rotatable between a first state (see FIG. 1) in which the sound emission directions face each other, and a second state (see FIG. 11) in which the sound emission direction faces upward (including an upward diagonal direction). In the first state of FIG. 1, the hood 3 is placed over the head H1, and the head H1 is positioned so as to be sandwiched between the left speaker 6a and the right speaker 6b, so that the user can hear sounds within the space defined by the hood 3. The speaker device 2 can be disposed in a state in which the speaker 6 and the support part 7 are spaced apart and substantially parallel to the side surface of the head H1 on the ear part H2 side. The angle of the speaker 6 can be adjusted independently of the support part 7, so that the angle can be adjusted according to the user's preference, regardless of the position of the mounting part 70. Therefore, the user can easily enjoy a personal acoustic space with stable acoustic characteristics without feeling any pressure, by using the speaker device 2 provided inside the hood 3.

[0045] In the second state of Fig. 11, the hood 3 is removed from the head H1, and the hood-type speaker device 1 is placed on the shoulder H3 or around the neck. Therefore, even when the hood 3 is removed and the speaker device 2 is placed on the shoulder H3, the user can hear the sound emitted from the speaker 6 while wearing the hood-type speaker device 1. Even in this case, the user can arbitrarily adjust the angle of the speaker 6 toward the ear H2. Even in the second state, the speaker device 2 can be stably positioned on the shoulder H3, so that the positions of the speaker 6 and the ear H2 can be stably maintained. Even when the user moves the shoulder H3, the positions of the speaker 6 and the ear H2 can be stably maintained relative to each other.

[0046] (Variation 1) Next, a first modified example according to the present embodiment will be described. A speaker device 2A built into the hood 3 of the hood-type speaker device 1A in Fig. 12 includes speakers 6 (a left speaker 6a and a right speaker 6b) and a mounting part 70A. The mounting part 70A includes a hanging cord 81 which is a hanging member.

[0047] The speaker device 2A includes a frame 5A bent into an obtuse L-shape and formed from a rod-like or plate-like member. One end 5A1 of the frame 5A is fixed to the speakers 6 (left speaker 6a and right speaker 6b) via a support 7. A hanging cord 81 is connected to the other end 5A2 of the frame 5A. The hanging cord 81 may further include an adjuster that can adjust the length, so that the height position of the speaker 6 can be adjusted. The frame 5A also includes a control circuit, a battery, etc., and can include the functions of the main body 4 of the speaker device 2.

[0048] As shown in FIG. 12, even when the hood type speaker device 1A is used by covering the head H1 with the hood 3, the support part 7 is pulled toward the head H1 by the hanging cord 81. However, since one end part 5A2 of the frame 5A can abut along the temporal part of the head H1, the left speaker 6a and the right speaker 6b connected to the frame 5A can be held at a predetermined interval, and thus the distance from the left and right ears H2 (or the head H1) can be stably maintained. Even if the user moves the head H1, the speaker device 2A follows the position of the head H1 because it is suspended by the mounting part 70A, and the position of the speaker 6 relative to the ears H2 can be stably maintained. Therefore, even in the first modification, the speaker device 2A and the hood type speaker device 1A can be configured to prevent the speaker 6 from coming into contact with the head H1 or the ears H2 and to be stably supported without a feeling of pressure.

[0049] (Variation 2) Next, a second modified example according to this embodiment will be described. The speaker device 2B built into the hood 3 of the hood-type speaker device 1B in FIG. 13 includes a main body 4, a frame 5 (left frame 5a and right frame 5b), a speaker 6 (left speaker 6a and right speaker 6b), and a mounting part 70B. The mounting part 70B includes a support part 7B (illustrated for the left arm 21 in FIG. 13, but similar for the right arm) formed by a base side rotating member 71 and a tip side member 72B, instead of the support part 7 in the speaker device 2. The tip side member 72B includes a recess 721, a screw hole 721a, an outer periphery 721b, and a rotation restricted part 721c at the end on the base side rotating member 71 side (see the enlarged view of part B in FIG. 5), and is connected to the base side rotating member 71 so as to be rotatable within the same angle range as the support part 7.

[0050] The mounting section 70B has a suspending member 8B instead of the suspending member 8. The suspending member 8B has a flat belt 84 (string-like body) and a buckle 85 that allows the length of the belt 84 to be adjusted. Both left and right ends of the belt 84 are rotatably connected to the tip side member 72B. The belt 84 is also pulled out towards the head H1 side via the outside of the speaker 6. Therefore, the force of the belt 84 towards the side of the head is regulated by the speaker 6. Rotation of the speaker 6 towards the inside (head H1 side) is regulated by a configuration similar to that of the speaker device 2. Therefore, contact between the belt 84 and the speaker 6 and the head H1 is prevented.

[0051] The hood type speaker device 1B also has a collar member 34 that is wrapped around the left and right side and the back of the head H1. The collar member 34 is formed, for example, on the inner lining 32 and a part of the lining 33, and has a U-shaped double structure with an open front in a plan view. The collar member 34 is formed to be less deformable (harder) than the upper region (head H1 side) of the hood 3. The left and right side portions of the collar member 34 are provided with concavely curved lower edge portions 341. The rear side portion of the speaker device 2B (for example, the frame 5 and the main body portion 4) is disposed inside the collar member 34.

[0052] When the speaker device 2B is placed so that the belt 84 is suspended from the head H1, the center of gravity is located behind the contact position between the belt 84 and the head H1. Therefore, a load is applied to the rear part of the speaker device 2B (the frame 5 and the main body part 4 in the above example) as it tries to rotate forward. However, in the hood-type speaker device 1B, by wearing the lower edge part 341 of the collar member 34 so as to contact the shoulder part H3, the posture of the built-in speaker device 2B is supported and the rear part of the speaker device 2B can be prevented from contacting the head H1 or the neck.

[0053] Therefore, in the second modification, the frame 5 can connect the left speaker 6a and the right speaker 6b so as to maintain a predetermined distance between them. This makes it possible to configure the speaker device 2B and the hood-type speaker device 1B that can be stably supported without a feeling of pressure.

[0054] Although the configurations of the hood type speaker devices 1, 1A, and 1B of the present embodiment have been described above, other configurations may also be applied to the hood type speaker devices 1, 1A, and 1B. For example, although the example in which the first axis P1 and the third axis P3 are arranged coaxially has been described in the present embodiment, the first axis P1 and the third axis P3 may be arranged at other positions that are not coaxial while being relatively parallel to each other.

[0055] Further, the speaker devices 2, 2B have been described as having the main body 4 between the left frame 5a and the right frame 5b, but the control circuit and the battery in the main body 4 may be provided in the left frame 5a or the right frame 5b, or in the left speaker 6a or the right speaker 6b, and the housing of the main body 4 may be omitted. In this case, the speaker devices 2, 2B may be connected so that the left frame 5a and the right frame 5b are relatively rotatable.

[0056] In this embodiment, the hood 3 is described as having a three-layer structure including the outer fabric 31, the inner lining 32, and the lining 33, but the number of layers is not limited to this, and it may have two layers or four or more layers.

[0057] In addition, in Figure 6, the method of connecting the frame 5, the base side rotating member 61 and the base side rotating member 71 is not limited to the method of fastening the screw member 53 to the female screw portion 612a of the base side rotating member 61, and the base side rotating member 61 and the base side rotating member 71 may be connected by other connecting methods as long as they are configured to be independently rotatable around the first axis P1 or the third axis P3 relative to the frame 5.

[0058] In addition, the specific configurations of the speaker device 2, the speaker device 2A, and the speaker device 2B described in the present embodiment can be arbitrarily combined. For example, in any of the speaker devices 2, 2A, and 2B, the belt 84 and the hanging cord 81 can be arbitrarily selected.

[0059] In the above embodiments, speaker devices 2, 2A, and 2B have been described that include a frame 5, a left speaker 6a and a right speaker 6b that are connected to the frame 5 and can be held at a predetermined distance from each other, and a mounting part 70 that is connected to the left and right positions of the frame 5 and can be suspended by the head H1.

[0060] This prevents the position of the speaker 6 from unintentionally shifting due to its own weight or the like, and allows the speaker devices 2, 2A, and 2B to be stably supported. Furthermore, even if the head H1 is moved left or right, the relative position between the speaker 6 and the ear H2 can be easily followed so as to remain substantially constant. Therefore, it is possible to configure a speaker device 2 that can be stably supported without a feeling of pressure. Furthermore, since the speaker device 2 can be stably supported on the head H1, it is also possible to install a function that requires precise control, such as ANC (Active Noise Control).

[0061] Moreover, in the speaker devices 2, 2A, and 2B in which the mounting portion 70 includes the left support portion 7a, the right support portion 7b, and the string-like body, the mounting portion 70 can be configured to be lightweight and simple.

[0062] Also, a configuration has been described in which the left support part 7a is formed in an L-shape extending from the rear to the upper part of the left speaker 6a and is connected to one end of the string-like body above the left speaker 6a, and the right support part 7b is formed in an L-shape extending from the rear to the upper part of the right speaker 6b and is connected to the other end of the string-like body above the right speaker 6b. This allows the support part 7 to be connected to the rear frame 5, while the connection position between the string-like body and the support part 7 can be located in the front where the speaker devices 2, 2A, and 2B can be stably supported.

[0063] In addition, in the speaker devices 2, 2A, 2B in which the left speaker 6a, the right speaker 6b, the left support part 7a and the right support part 7b are connected to the frame 5 in such a way that the angle can be adjusted independently, the orientation of the speaker 6 can be set arbitrarily according to the user's preference while avoiding the string-like body or the support part 7 from coming into contact with the head H1.

[0064] Furthermore, the rotation of the left support part 7a is restricted so that it does not approach the left ear H2 side of the left speaker 6a, and the rotation of the right support part 7b is restricted so that it does not approach the right ear H2 side of the right speaker 6b, so that it is possible to prevent a part of the support part 7 or the string-like body from coming into contact with the head H1.

[0065] Also, a configuration has been described in which the left speaker 6a and the right speaker 6b are connected to the frame 5 so as to be rotatable about the first axis P1 and the second axis P2 different from the first axis P1, respectively, and the left support part 7a and the right support part 7b are connected to the frame 5 so as to be rotatable about the third axis P3 and the fourth axis P4, respectively. As a result, the left and right speakers 6 and the support parts 7 are configured so as to be rotatable in two axial directions, and therefore it is possible to configure the speaker devices 2, 2A, 2B which allow for angle adjustment with a high degree of freedom.

[0066] Furthermore, the speaker device 2, whose string-like body includes multiple hanging cords 81, can be suspending some of the hanging cords 81 in front of the head H1 and other hanging cords 81 behind the head H1, thereby stably supporting the speaker device 2 so that it does not slip off the head H1.

[0067] Also, a configuration has been described in which the left speaker 6a and the right speaker 6b are connected to the frame 5 so as to be rotatable between a first state in which the sound emitting directions face each other and a second state in which the sound emitting direction faces upward. This allows the user to use the speaker device 2, 2B (2A) in any mode according to the situation, preference, etc.

[0068] Also, the frame 5 has a left frame 5a connected to the left speaker 6a and a right frame 5b connected to the right speaker 6b, and the left frame 5a and the right frame 5b are configured to be openable and closable via the hinge portion 41. This allows the speaker devices 2, 2B (2A) to be stored compactly.

[0069] Moreover, the hood type speaker devices 1, 1A, 1B, which include the above-mentioned speaker devices 2, 2A, 2B and the hood 3 incorporating the speaker devices 2, 2A, 2B, are configured to be suspended from the head H1 by the mounting part 70, so that even if a flexible material is used for the hood 3, the position of the speaker 6 can be prevented from shifting due to its own weight, etc. Also, even if the head H1 is moved left and right, etc., it can be easily made to follow the movement. Therefore, it is possible to configure a hood type speaker device 1 that can be stably supported without a feeling of pressure.

These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
