Description

  The present invention relates to a speaker device including a front panel, and more particularly to a speaker device installed in a public place.

  Conventionally, various speaker devices are installed in public places such as gymnasiums and hospitals. In such a speaker device installed in a public place, an impact may be applied to the front panel due to external factors.

  As a speaker device used in such an environment, for example, in Patent Document 1, each speaker such as a woofer and a tweeter and a bass reflex port are installed on a baffle plate also serving as a front panel. The peripheral part of each speaker or bass reflex port is formed so as to protrude forward from a baffle plate (front panel). The projecting portions are lattice-like when viewed from the front, and function as a reinforcing framework. Thereby, damage to the speaker and the speaker device itself is prevented from impact applied from the outside (for example, impact caused by hitting a ball or the like in Patent Document 1).

JP 2009-124593 A

  However, in the speaker device described in Patent Document 1, since a grid-like framework is formed so as to surround each speaker, the sound emission directivity on the front side of each speaker is limited as compared with the case where no framework is provided. The sound emission characteristic is deteriorated due to the phenomenon that the sound quality characteristic and the frequency characteristic deteriorate due to the influence of the sound reflected in the frame and emitted in the front direction. In addition, the shape of the lattice must be set according to the arrangement of the speakers, and the front (front) side design of the speaker device is limited.

  It is an object of the present invention to provide a speaker device that can prevent damage to the speaker and the speaker device itself against an impact from the front side, suppress deterioration of sound emission characteristics in the front direction, and ensure a degree of freedom in design of the front panel. Is to realize.

The present invention relates to a speaker device including a casing having a predetermined shape. The baffle plate of the speaker device is formed on the front side wall surface of the baffle plate from the front side wall surface in a position that does not overlap with the plurality of openings in the front panel when the speaker device is viewed from the front and in a region different from the speaker installation region. A standing member formed in a shape protruding in a vertical direction is provided. At least a part of the end portion of the standing member opposite to the front side wall surface is in contact with the rear side wall surface of the front panel.

  In this configuration, the front panel, which has a plurality of openings and does not have a relatively high strength, is supported from the inside by a standing member of a baffle plate fixed inside the housing. Thereby, the intensity | strength with respect to the external impact of a front panel can be improved. Moreover, since the standing member is installed so as not to overlap the opening of the front panel, the standing member cannot be seen from the front side, and the design is not impaired. Moreover, since the standing member is installed according to the shape of the opening of the front panel, the degree of freedom in designing the opening of the front panel is improved. In addition, since the standing member is arranged in an area different from the installation area of the speaker, the sound emission directivity on the front side of the speaker is not limited, and the sound is reflected in the framework and emitted in the front direction as in the prior art. There is no sound. Therefore, sound quality characteristics and frequency characteristics are not deteriorated, and sound emission characteristics of the speaker are not impaired.

  In the speaker device according to the present invention, the standing member includes a first standing member that abuts against the rear side wall surface of the front panel, and a second standing member having a height lower than that of the first standing member. .

  In this configuration, the standing member is composed of a first standing member that contacts the front panel and a second standing member that does not contact the front panel, and the first standing member is formed by the second standing member. It is connected.

  In this configuration, not all the standing members support the front panel, but the front panel is supported by a part of the standing members (first standing members) and the other standing members (second standing members). ) Reinforce some of the standing members (first standing members). Thereby, a space can be provided between the front panel and the second standing member in a region where the standing member is formed while realizing support of the front panel. As a result, the sound emission directivity on the front side of the speaker is hardly restricted, deterioration of sound quality characteristics and frequency characteristics can be prevented, and sound emission characteristics are improved.

  In the speaker device of the present invention, the plurality of openings are substantially square or substantially rectangular when viewed from the front, and are arranged along the vertical and horizontal directions. The first standing member is installed in the vicinity of the corners of the plurality of openings arranged. The 2nd standing member is installed along the side of a plurality of openings arranged.

  In this configuration, since the first standing member is disposed only at the corner portion of the opening, the sound emission characteristics can be further improved while effectively supporting the front panel.

  Further, the speaker device of the present invention includes a plate-shaped blindfold member that is installed on the rear side wall surface of the front panel and has a plurality of predetermined holes.

  In this configuration, by arranging a blindfold member, for example, a punching metal, the standing member on the back side of the front panel can be made more difficult to see from the outside.

  According to the present invention, it is possible to prevent the speaker and the speaker device itself from being damaged by an impact from the front side. Furthermore, it is possible to prevent the deterioration of the sound emission characteristics of the speaker to the sound emission area on the front side, and to design the front panel more freely.

Only the front panel 21 exists. For this reason, the sound emission directivity on the front side of the speaker SP is not limited, and there is no sound that is reflected by the framework and emitted in the front direction as in the prior art. Therefore, the sound quality characteristic and the frequency characteristic are not deteriorated, and the sound emission characteristic of the speaker SP can be prevented from being deteriorated.

  Further, in the structure of the present embodiment, only the bosses 311-314, 321-324, 331-334 are in contact with the front panel 21, and the tips of the standing walls 351-353, 361-367 and the rear surface 21R of the front panel 21 A space is formed between the two. Therefore, a spatially connected region on the front side of the speaker SP is expanded, and sound can be emitted from the entire front surface of the front panel 21 more effectively. That is, the sound emission characteristics can be further improved.

  In the above description, a configuration in which nothing is installed in the opening of the front panel 21 is shown as an example. However, a blindfold member such as a punching metal in which a large number of through holes having a predetermined diameter are arranged is used as the front panel 21. You may arrange | position on the back surface 21R side. Thereby, the fall of the appearance of the speaker apparatus 10 can be prevented further effectively.

  Moreover, the formation pattern of the opening part of the front panel 21 shown by the above-mentioned description is an example, and you may use other various opening designs. In this case, a boss or a standing wall may be formed on the baffle plate so as to overlap the frame formed by the opening.

  Further, in the baffle plate 30, the boss, the standing wall, and the outer peripheral wall may be formed separately from the main substrate 31 and bonded with an adhesive or the like. However, by integrally molding, it is possible to prevent stress when a force is applied from the outside from being concentrated on the bonded portion, and it is possible to form a baffle plate 30 with higher strength.
