Description

  The present invention relates to a speaker system. More specifically, the present invention relates to a large-sized television speaker system that does not take up space, is easily connected, and has excellent sound quality.

  In recent years, large thin televisions such as plasma televisions and liquid crystal televisions have been rapidly spread. As a result, it is considered that the potential demand for home audio-visual (AV) systems (so-called home theater systems) using such large-sized flat-screen televisions is rapidly increasing.

  However, in practice, such home theater systems are not as popular as potential demand. The reasons are as follows: (1) When considering the housing situation in Japan, there is no place to install a speaker system for a home theater. (2) The connection of each device for the system is complicated, and the wiring after the connection is It is conceivable that it is unsightly exposed in the room, and (3) many tall speakers (vertical speakers) sold as a set with a large TV tend to fall down, so many people dislike installation.

  On the other hand, only the built-in speaker in a large television has insufficient sound quality compared to a large screen image, so that movies and sports cannot be fully enjoyed.

In order to solve the above problems, television storage racks with built-in speakers have been proposed (see Patent Documents 1 and 2). However, since the rack of Patent Document 1 needs to be completed by assembling each unit containing an amplifier and a speaker, the troublesome connection of each unit (each device) is not eliminated at all. Furthermore, this rack is not devised for improving the sound quality. Moreover, although the rack of patent document 2 attaches a speaker to the support member of a rack, and uses the support member as an acoustic tube, it is inadequate about the surround effect for home theaters. Furthermore, since this rack has the speaker attached to the support member, the speaker is exposed to the outside and is not excellent in aesthetics.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

  FIG. 1 is a schematic perspective view illustrating a speaker system according to a preferred embodiment of the present invention. FIG. 2 is a front view of the speaker system of FIG. FIG. 3 is a cross-sectional view of the speaker system of FIG. 1 when viewed from above. FIG. 4 is a cross-sectional view of the speaker system according to a more preferred embodiment as viewed from above. The speaker system 100 includes a horizontal platform 10 and legs 20 that hold the horizontal platform 10 horizontally. The horizontal platform 10 includes a left speaker 11L, a right speaker 11R, and a center speaker 11C. Preferably, the left speaker 11L, the right speaker 11R, and the central speaker 11C each have at least one tweeter and at least one woofer. In the illustrated example, the left speaker 11L and the right speaker 11R each include one tweeter and one woofer. The central speaker has a tweeter and two woofers. The type, configuration, and number of units included in each speaker can be appropriately selected according to the purpose. If necessary, at least one duct is provided in at least one of the left speaker 11L, the right speaker 11R, and the center speaker 11C. By providing the duct, the sound quality of the low range can be further improved. In the illustrated example, one duct is provided for each of the left speaker 11L, the right speaker 11R, and the central speaker 11C. The shape, number, arrangement position, and the like of the duct can be appropriately selected according to the purpose.

  The left speaker 11L, the right speaker 11R, and the center speaker 11C of the horizontal base unit 10 have their respective speaker unit axes (that is, the centers of the tweeter and woofer diaphragms) on a straight line in the horizontal direction (on the one-dot chain line H in FIG. 1). ). By adopting such a configuration, it is possible to realize a very excellent sound movement feeling. As a result, an excellent surround system can be realized with a simple configuration.

  The horizontal platform 10 functions as an enclosure for the left speaker 11L, the right speaker 11R, and the central speaker 11C. At the same time, the horizontal platform 10 has sufficient characteristics (for example, strength, breadth, and stability (no wobbling)) to become a mounting table for a large television. As a result of the horizontal base 10 having a sufficient area for mounting a large TV, the volume space of the left speaker 11L, the right speaker 11R, and the central speaker 11C is increased, so that the sound quality of these speakers (particularly, Low range) can be significantly improved.

  The horizontal platform 10 includes a partition wall 12 that defines the volume spaces of the left speaker 11L, the right speaker 11R, and the central speaker 11C. The partition wall 12 also functions as a reinforcing member for the horizontal platform 10 and is given sufficient strength to serve as a mounting table for a large television. Preferably, as shown in FIG. 3, the partition wall 12 is provided obliquely with respect to the axial direction of the speaker. By adopting such a configuration, the occurrence of standing waves can be reduced. The angle defined by the partition wall 12 and the axial direction of the speaker (the degree of deviation in the oblique direction: the angle α in FIG. 3) can be appropriately set according to the purpose, but is typically 5 to 45 degrees. .

  Preferably, as shown in FIG. 4, buffer spaces 15 are defined between the left speaker 11L and the central speaker 11C, and between the central speaker 11C and the right speaker 11R. The buffer space 15 is formed, for example, by providing two partition walls 12 between the left speaker 11L and the central speaker 11C and between the central speaker 11C and the right speaker 11R, and providing a space therebetween. obtain. By defining the buffer space 15 as described above, it is possible to prevent an adverse effect due to the interaction between the speakers and to obtain a speaker system having further excellent sound quality. Any appropriate sound absorbing material may be disposed in at least a part of the buffer space 15 as necessary. More specifically, the sound absorbing material may be filled in the entire buffer space 15, or the sound absorbing material may be attached to the partition wall 12 on the buffer space 15 side. By arranging the sound absorbing material, the interaction between the speakers can be prevented even better.

  Preferably, as shown in FIG. 3, the horizontal base portion 10 further includes a wiring housing portion 13. That is, all the lead wires on the side of the speakers (the left speaker 11L, the right speaker 11R, and the central speaker 11C) are connected and accommodated in the horizontal platform 10. As a result, the unsightly that the wiring is exposed to the room is eliminated. The wiring housing part 13 has, for example, a winding structure (more preferably, a reel structure) 14. By adopting a winding structure, it is possible to adjust the length at which the TV side end of the speaker lead wire is exposed to the outside of the speaker system, so that the wiring exposed to the room (outside the speaker system) is minimized. Can do. In addition, since the connection of the speakers (and each device such as an amplifier as necessary) has been completed in the wiring accommodating portion 13, the user can connect the speaker lead wire to the TV-side end of the speaker lead wire. Just connect the parts. Therefore, a user-friendly large-sized television speaker system in which the complexity of the connection is eliminated can be obtained.

  The leg portion 20 has sufficient characteristics (for example, strength and stability (not wobble)) to hold the horizontal base portion 10 on which a large television is placed horizontally. The structure of the leg portion 20 is not particularly limited as long as the horizontal base portion 10 can be stably held horizontally, but preferably supports the entire side portions of the horizontal base portion 10 as shown in FIG. Such a structure is excellent in retention stability. Furthermore, by hollowing out the interior, the legs 20 can also function as a volume space for the speaker system, or additional speakers and / or various devices can be incorporated (discussed below).

  Preferably, the legs 20 can be equipped with further speakers. The type and configuration of the speaker mounted on the leg 20 can be appropriately selected according to the purpose. The speaker may be equipped on one of the legs 20 or on both. When both are equipped, both may be equipped with the same type of speakers or different types of speakers. Typically, one of the legs 20 is equipped with a subwoofer. In that case, the other of the legs 20 may be equipped with an amplifier. By adopting such a configuration, a more realistic sound field can be reproduced. In addition, the wiring of the equipment equipped in the leg part 20 can also be accommodated in the wiring accommodating part 13 of the horizontal base part 10.

  Although the preferred embodiments of the present invention have been described so far, the present invention is not limited to these embodiments. For example, you may install a speaker in the side part and / or back part of the horizontal base part 10. FIG. Further, for example, a vibration damping material or a sound absorbing material (for example, cork or foamed polyethylene) may be disposed between the horizontal base 10 and the leg 20. Further, for example, the leg portion 20 may be used as an article storage portion without any equipment. In the above embodiment, the partition wall is provided obliquely, but the partition wall may be provided parallel to the axial direction of the speaker. Therefore, the buffer space may be defined parallel to the axial direction of the speaker.

  The speaker system of the present invention can be suitably used as a large TV speaker and / or as a large TV rack.
