DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loudspeaker, particularly a position selectable loudspeaker capable of freely changing a position of a loudspeaker for a middle range and / or a high range to obtain the best directivity. It is.

[0002]

2. Description of the Related Art Among personal computers (abbreviations for personal computers), portable notebook personal computers in which a liquid crystal display (LCD) and a main body of a personal computer are integrated and are approximately in the size of an A4 size notebook are hard and soft. With the improvement, music and video can be enjoyed.

[0003]

The notebook personal computer is designed to be compact so that it can be formed, and most of the notebook personal computers have a built-in PCM sound source and a plurality of speakers for stereo listening. However, due to its mechanism, the loudspeakers that can be mounted must be small and the output is only about 1 to 2 W at most, so the sound quality is relatively poor and the directivity is wide. There are many issues that need to be solved, such as the absence of

In view of this situation, the present invention sets a speaker in a best position in accordance with a use mode of a personal computer or the like, so that the directivity can be freely changed and the position can be easily selected. It will not be provided.

[0005]

In order to achieve the above object, a position selectable speaker according to the present invention has a built-in woofer, a pedestal having a port formed therein, and a mid-range and / or high-range. The speaker member includes a speaker box having a built-in speaker, and an arm member for connecting the pedestal portion and the speaker box. The arm member is adjustable in height, and is horizontally rotatable with respect to the pedestal portion. The speaker box is characterized by being rotatable in the front-rear and / or horizontal direction with respect to the arm member.

According to a second aspect of the present invention, the pedestal has a required gap between a bottom surface thereof and a mounting surface, and sound is emitted through the gap. A speaker whose position can be selected.

According to a third aspect of the present invention, the arm member is located between the base end on the pedestal side, the upper end on the speaker box side, and the base end and the upper end. The position selectable speaker is characterized in that a joint portion is formed at a portion of the speaker and the height can be adjusted at the joint portion.

According to a fourth aspect of the present invention, the arm member comprises a plurality of rods.
A position selectable speaker characterized in that each rod is configured to be vertically expandable and contractible.

[0009]

The position-selectable speaker according to the present invention is:
Since the pedestal section containing the bass speaker and the speaker box containing the mid-range and / or high-range speakers are connected by a height-adjustable arm member, the mid-range and / or Alternatively, the height and sound emission direction of a speaker box having a built-in high-frequency speaker can be freely selected, and the sound can always be heard at the best position.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a position selectable speaker according to the present invention will be specifically described below with reference to the accompanying drawings.

As shown in FIG. 1, the position-selectable speaker 1 of the present invention includes a pedestal section 3 having a woofer 2 built therein, a speaker box 6 having a mid-range and / or high-range speaker 5 built therein, It comprises an arm member 7 for connecting the pedestal portion 3 and the speaker box 6.

The pedestal portion 3 is formed of a hollow body having a semicircular cross section. The bottom portion 3a is formed in a concave arc shape, and a required space X with respect to a mounting surface D such as a desk. Is formed, bass sound radiated from the woofer 2 is effectively emitted from the gap X, and more effective by forming the duct port 4 at a required portion of the peripheral surface of the hollow body. Characteristic bass can be obtained.

The speaker box 6 arranged above the pedestal portion 3 has, for example, a built-in medium-sound skaker and a high-frequency tweeter. However, the built-in speakers are not particularly limited. For example, in the case of two ways, the woofer is in the base, the tweeter is in the speaker box 6, and in the case of three ways, the woofer is in the base, the squawker and the tweeter are in the speaker box 6,
Further, by mounting a super tweeter in addition to the squawker and the tweeter, a four-way can be obtained.

The pedestal section 3 and the speaker box 6 are connected by an arm member 7. The arm member 7 is basically adjustable in height. The member 7 includes an arm 7a fixed to the pedestal portion 3 so as to be rotatable in a horizontal direction, an arm 7b having a relatively long length connected to the arm 7a via a first joint 8, and an arm 7b. An arm 7c having a shorter length than that connected to the second joint 8 via the second joint 8 is fixed to the rear surface of the speaker box 6 so as to be rotatable in the horizontal direction. And an arm 7d connected to the arm 7c via the arm 7c. The arm connected at each joint 8 can be rotated at least in the vertical direction about the joint 8 by
The distance between the pedestal portion 3 and the speaker box 6, that is, the height can be freely changed.

An arm member 17 of the position-selectable speaker 11 shown in FIG. 2 has a required length and has three cylindrical arms 7a, 7b,
7c is configured to be slidable in the vertical direction and fixed at an arbitrary position.
a is a first joint 18 which is in contact with the pedestal 13, and an arm 17 c is horizontally rotatable at a second joint 18 which is in contact with the speaker box 16. If the arm member that connects the box can at least adjust the height,
There is no particular limitation on its structure.

In FIG. 2, reference numeral 12 denotes a woofer,
13 is a pedestal portion, 13a is a bottom portion of the pedestal portion 13, X is a gap formed between the pedestal portion D, 14 is a duct port formed in the pedestal portion 13, and 15 is a middle region and / or A high frequency speaker 16 is a speaker box and has basically the same configuration as the position selectable speaker 1 shown in FIG.

There is no particular limitation on the length of the arm member. However, if the distance between the pedestal portion and the speaker box is large, the overall structure needs to be strengthened, which may increase the cost. , The total height is 30-35
cm is preferable.

Furthermore, the position-selectable speaker of the present invention can be used by externally attaching it not only to a notebook-type personal computer but also to a desktop-type personal computer, a liquid crystal television, a bedside speaker, and the like. Is basically placed horizontally on a desk or the like for use, but it can also be mounted on a wall using a separate mounting tool.

[0019]

The position-selectable speaker according to the present invention comprises a pedestal section containing a woofer and a speaker box containing a mid-range and / or high-range speaker with arm members that can be adjusted in height. In addition to the connection, the pedestal portion and the speaker box are rotatable at least in the horizontal direction with respect to the arm member. The high frequency speaker can be arranged at the best position.

In particular, the position-selectable speaker according to the present invention has a directivity of a speaker box containing a middle-range and / or a high-range speaker when arranging speakers having different sound ranges at a predetermined interval. Can be obtained freely, can be made compact when not in use, and has many practical advantages such as easy operation and simple structure.
