The present invention relates to an audio player mounting mechanism for mounting a portable audio player on a device such as an AV amplifier.

Conventionally, a docking station for inputting music (audio signal) reproduced by a portable audio player to another apparatus such as an AV amplifier is known (see, for example, Patent Document 1).

For example, the docking station of Patent Document 1 is provided with an opening that matches the shape of the portable audio player, and by providing a connector at the bottom of the opening, simply inserting the portable audio player into the opening, an AV amplifier, etc. In this configuration, an audio signal can be supplied to another device.

Japanese Unexamined Patent Publication No. 2009-110645

However, the opening of Patent Document 1 is dedicated to the shape of the portable audio player and cannot be connected to portable audio players having different shapes. On the other hand, when the opening is enlarged and a portable audio player of any shape can be mounted, the portable audio player is inclined with respect to the connector when the user inserts or removes the portable audio player from the connector (straightly The connector may be damaged.

Therefore, an object of the present invention is to provide an audio player mounting mechanism that can prevent damage to a connector when the user inserts or removes the audio player from the connector.

An audio player mounting mechanism according to an aspect of the present invention includes a housing, a connector provided on an upper surface of the housing, and an upper surface side of the housing that is closer to the back side of the housing than the position of the connector. An audio player mounting mechanism including a handle provided at a position, wherein the connector is installed at a predetermined angle on an upper surface of the housing, and the handle extends at the same angle as an installation angle of the connector. It has a shape having a vertical part and a grip part sandwiched between the vertical parts and extending in parallel with the upper surface of the housing, so that the back surface of the audio player comes into contact when the audio player is connected to the connector. It is provided at a position.

According to this structure, the user can carry the speaker device or receiver device equipped with the audio player mounting mechanism by grasping the parallel part of the handle. Moreover, it can also be used for hanging by hanging the handle on a hook or the like. Then, by leaning the back surface of the audio player against the handle, the audio player can be installed at the same angle as the inclination of the connector, and the audio player can be prevented from being inclined in the back direction. Thus, since the portable audio player does not tilt further to the back side by the handle, it is possible to prevent the user from further tilting to the back side when the user inserts or removes the audio player from the connector. Damage can be prevented.

In addition, the handle may be firmly fixed to the casing by being inserted into a recess provided on the upper surface side of the casing and being fixed to the casing.

Further, a mode in which a fixing portion for fixing the handle to the concave portion is provided from the inside of the housing is also possible. For example, the handle is firmly fixed with screws from the inside of the housing. In this case, a screw hole is formed in a concave portion of the housing at a place where the screw is inserted, but the screw hole is filled by inserting the screw. Therefore, even when the casing is an enclosure of a speaker box, the sealing performance of the enclosure is not affected.

According to the present invention, when the user inserts or removes the audio player from the connector, the connector can be prevented from being damaged.

FIG. 12A is a diagram illustrating an application example in which a handle is provided on the housing of the rectangular parallelepiped speaker device, and FIG. 12B is a diagram illustrating an application example in which a handle is provided on the housing of the receiver device. .

A speaker device provided with the speaker box of the present invention will be described with reference to the external structural views of FIGS. In the present embodiment, the front direction of the speaker device is described as z, and the back direction is described as -z. Also, the upper direction is described as y, the lower direction is described as -y, the right direction is described as x, and the left direction is described as -x.

The speaker device 1 includes an octagonal frustum-shaped casing 11 which is a speaker box, and a speaker unit 12 provided on the bottom surface on the front side of the casing 11. An octagonal cylindrical front cover 13 is connected to the front surface of the housing 11. In addition, although the case 11 of this embodiment demonstrates octagonal frustum shape, if it is a polygonal frustum shape which has several side surfaces, such as a triangular frustum, a pentagonal frustum, a hexagonal frustum, for example, what kind of thing? Even a case having a simple shape belongs to the technical scope of the present invention.

An opening 19 and terminals 20 are provided on the bottom surface on the back side of the housing 11. The housing 11 has a front-side bottom area larger than a back-side bottom area.

The casing 11 shown in the present embodiment is composed of three parts: a side part 101, a front side bottom part 102, and a back side bottom part 103. However, the number of parts can be reduced by, for example, integrating the bottom part 103 and the side part 101 on the back side, or the number of parts can be further subdivided by dividing the side part 101 into eight parts. It is also possible to increase.

The side part 101 of the housing 11 is made of a metal material, the bottom part 102 on the front side is made of wood, and the bottom part 103 on the back side is made of a resin material. The material of each component is not limited to this example, and can be changed as appropriate according to the required sound quality and housing strength.

The bottom part 102 on the front side of the housing 11 is provided with two circular holes in order to install the two speaker units 12. These two holes serve as the unit installation portion of the present invention. The bottom surface part 102 functions as a baffle that fixes the speaker unit 12 and spatially separates the front side and the back side of the speaker unit 12. Among the side parts 101 of the housing 11, a front cover 13 having a rectangular tube shape with an octagonal bottom is connected to the front side. The front cover 13 has an open bottom on the back side, is connected to the front side of the side part 101, and can sandwich the periphery of the bottom part 102 on the front side. The bottom surface on the front side of the front cover 13 is partially opened in a circular shape so as to be narrowed down into a truncated cone shape toward the inside of the square tube. In the middle of the narrowed-down portion, eight cylindrical recess portions are provided at equal intervals. The front cover 13 is screwed to the side part at this recessed portion.

In this way, the front cover 13 has a function of pressing the bottom part 102 of the speaker unit 12 against the side part 101 and fixing it. Further, a punching metal 14 is sandwiched between the front cover 13 and the bottom part 102 of the housing 11. The punching metal 14 covers the entire front surface of the speaker unit 12 and functions as the protective member.

As described above, since the front cover 13 is entirely open on the bottom surface on the back side, when the front cover 13 is manufactured by resin integral molding, it can be extracted from the mold to the front side. ing. At this time, since the bottom area on the front side of the front cover 13 is slightly smaller than the bottom area on the back side, the front cover 13 can be easily extracted from the mold in the front direction during the manufacturing.

However, the front cover 13 is not an essential configuration in the present invention. For example, as shown in FIG. 7, the bottom part 102 can be fixed to the side part 101 by screwing or the like.

Note that the speaker unit 12 of the present embodiment is provided with two speaker units: a bass speaker unit with a relatively large diaphragm area and a speaker unit for medium and high sounds with a relatively small diaphragm area. Two speaker units may be provided, the number of units may be one, or a larger number may be provided.

The bottom part 103 of the housing 11 is a thin plate-like resin member having an octagonal bottom surface, and is screwed to the side part inside the housing 11. The bottom surface component 103 seals the back surface of the housing 11 in this way, and causes the housing 11 to function as an enclosure.

Further, a part of the bottom part 103 has an opening 19 that is opened in a rectangular shape with rounded corners. The opening 19 functions as a bass reflex port that provides air communication between the enclosure of the housing 11 and the outside.

In addition, the bottom part 103 is provided with a plurality of holes for installing the terminals 20. This hole corresponds to the terminal installation portion of the present invention. However, the periphery of the terminals 20 is sealed with a non-breathable elastic body such as silicon rubber. That is, silicon rubber having holes matched to the shapes of the terminals 20 is pressed around the terminals 20, and the terminals 20 are inside the housing of the bottom part 103 in a state where the silicon rubber is pressed. It is fixed with screws.

Terminals 20 include a power supply terminal and an audio input terminal. The analog audio signal input from the line input terminal is amplified by a power amplifier (not shown) built in the speaker device 1, supplied to the speaker unit 12, and output as sound in the front direction of the housing 11. Further, a bass component is emitted from the opening 19. The speaker device 1 may include a D / A converter so that a digital audio signal is input and converted into analog audio.

On the other hand, as shown in FIGS. 4 to 6, the leg portion 21 is provided in the downward direction (−y direction) of the side part 101 of the housing 11. By bringing the leg portion 21 into contact with a horizontal surface such as the ground, the speaker device 1 can be stably placed on the ground or the like with the lower surface side of the side part 101 as the placement surface. However, the leg portion 21 is not an essential configuration in the present invention.

The speaker box having such a truncated pyramid-shaped casing 11 has a larger volume as an enclosure than a pyramid-shaped speaker box having the same depth length, and has a volume close to a general rectangular parallelepiped casing structure. . Further, as shown in FIG. 6, when any one of the side surface parts 101 is placed on a horizontal surface such as the ground, the speaker unit is slightly inclined upward from the horizontal direction.

Moreover, as shown in FIG. 8, it is also possible to make it contact with horizontal surfaces, such as the ground, by making the back side of the housing | casing 11 into a mounting surface. In addition, although the terminals 20 are provided in the back, since these terminals are all female terminals without a protrusion, there is no problem in making the back side contact with a horizontal surface. Moreover, since the speaker device 1 has a built-in battery (not shown), it can be driven even when a power cable is not connected. In the case of the example illustrated in FIG. 8, the sound output direction of the speaker unit 12 is vertically upward, so that sound can be output omnidirectionally in the entire circumferential direction of the speaker device 1. Such an aspect of outputting sound in all-around directions is particularly suitable when the listener is not present at a certain position, such as when the speaker device 1 is installed outdoors.

Next, in FIG. 1 to FIG. 6, the pedestal 31 provided on the upper surface portion of the side part 101 of the housing 11 will be described. The pedestal 31 has a quadrangular pyramid shape that protrudes upward from one surface of the side surface component 101. The side surface of the pedestal 31 is integrally formed with the side surface component 101 of the housing 11, and the upper surface of the pedestal 31 is made of a plate-shaped resin member. The upper surface of the pedestal 31 projects to the front side from the side part 101 and is parallel to the upper surface of the front cover 13.

On the upper surface of the pedestal 31, a user interface 15 including a power switch, a volume switch, and the like, an audio player mounting portion 17 on which a portable audio player is placed, and a connector 18 connected to the portable audio player are provided.

The speaker device 1 inputs a digital audio signal from a portable audio player connected via a connector 18. The input digital audio signal is converted into an analog audio signal by a built-in D / A converter (not shown), amplified by a power amplifier (not shown), supplied to the speaker unit 12, and the front of the housing 11 The sound is output in the direction. Further, a bass component is emitted from the opening 19. Note that a decoder may be incorporated in the speaker device 1, and encoded data such as MP3 may be input from a portable audio player and decoded by the decoder. Of course, an aspect may be adopted in which an analog audio signal is input from a portable audio player. Thus, the speaker device 1 also has a function as an audio receiver (however, the function as a receiver is not essential in the present invention).

FIG. 9 (A) is a left side view of a speaker device equipped with an audio player, and FIG. 9 (B) is a partially transparent side view.

The audio player mounting portion 17 has a structure in which the upper surface of the pedestal 31 is recessed in a truncated pyramid shape, and the connector 18 is provided on the bottom surface of the recessed portion. The connector 18 is installed obliquely toward the back direction, and the portable audio player is installed obliquely. This makes it easier to visually recognize the front portion of the portable audio player from above with the portable audio player placed.

However, when the portable audio player is tilted obliquely, it is placed on the housing 11 in an unstable state. Therefore, the speaker device 1 of the present embodiment can support the portable audio player using the handle 16 for the user to carry the speaker device 1 by hand.

The handle 16 is made of a rod-shaped metal member, and is positioned at a predetermined distance (for example, about 10 cm) from the pedestal 31 and the vertical portion 161 extending upward from the side part 101 of the housing 11 so as to sandwich the left and right sides of the pedestal 31. And has a gripping portion 162 that is bent vertically and arranged parallel to the upper surface of the pedestal 31.

The handle 16 is screwed to the side part 101 of the housing 11. That is, as shown by a broken line in FIG. 6, the side part 101 of the housing 11 has a concave portion 51 that is recessed in a columnar shape in order to fit the end portion of the handle 16. An end portion of the handle 16 is inserted into the recess 51 and is firmly fixed by a screw (fixing portion) 52 from the inside of the housing 11. Although the screw hole of the recess 51 is inserted into the screw hole, the screw hole is filled by the screw 52 being inserted, so that the sealing performance of the enclosure is not affected. The user can carry the speaker device 1 by grasping a portion of the handle 16 parallel to the base 31. In addition, the speaker device 1 can be suspended by hanging the handle 16 on a hook or the like.

Further, the handle 16 has a vertical portion 161 that extends upward at the same angle as the inclination of the connector 18 on the back side from the installation position of the connector 18, and has a gripping portion 162 sandwiched between the vertical portions 161. Yes. Therefore, as shown in FIGS. 9A and 9B, the portable audio player can be placed at the same angle as the inclination of the connector 18 by leaning the portable audio player against the handle 16, It is possible to prevent the audio player from being excessively inclined in the rear direction. Thus, since the portable audio player does not tilt further to the back side by the handle 16, it is prevented that the user further tilts to the back side when the user pulls out the plug-in audio connector from the connector 18. Damage to the connector 18 can be prevented.

Also, as shown in FIG. 10, when the back side of the casing 11 is brought into contact with a horizontal surface such as the ground, the handle 16 supports the portable audio player, and the portable audio player can be stably placed. .

On the other hand, when the portable audio player is not mounted, as shown in FIG. 11, the speaker 16 can be placed with the handle 16 in contact with the horizontal plane and the upper surface side of the speaker device 1 vertically downward. Alternatively, when the height of the portable audio player is lower than the height of the handle 16, the speaker device 1 can be placed with the upper surface side of the speaker device 1 vertically downward even when the portable audio player is mounted.

In this case, the speaker unit 12 is greatly inclined upward (about 45 degrees) rather than bringing the lower surface side of the speaker device 1 into contact with the horizontal plane. Therefore, the direction of sound emission can be changed according to the usage situation. That is, in the speaker device 1 of the present embodiment, the speaker unit is slightly inclined upward from the horizontal direction, the speaker unit is upward about 45 degrees, and the speaker unit is directly upward. Can be selected.

Further, the handle 16 and the connector 18 are not limited to a polygonal frustum-shaped casing, but can be attached to a casing of a general rectangular parallelepiped speaker device as shown in FIG.

Further, the present invention is not limited to the speaker device having the receiver function, and an application example in which the handle 16 and the connector 18 are provided on the upper surface of the housing of the receiver device as shown in FIG.

In any case, the user can carry the apparatus by grasping the handle 16 and can prevent the portable audio player from being inclined in the back direction.
