DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker system for an audiovisual system, and more particularly to a speaker system which can be freely decorated with an arbitrary image such as a character or an image (hereinafter simply referred to as an image).

[0002]

2. Description of the Related Art Conventionally, in the case of an AV speaker, a surface mounting portion has a woven or knitted fabric (net), a processed product of a metal plate (punching, lath net, wire net) and a synthetic resin formed product fixed thereon. The ones that are fitted are mainly used. Some of these exterior parts have characters or pictures formed in advance on a net or the like, but many of them have a black or brown appearance and are dark and uniform. In addition, there has been a demand for a smaller, thinner, and lighter speaker for saving space, such as recent housing situations.

[0003]

However, in the above-mentioned conventional speaker system for AV, the existing fabric and
The knitted fabric (net) or the metal covering portion is fixed or attached in advance, and the covering portion cannot be adjusted according to the taste such as the color or brightness of the room. . In addition, thinner and lighter loudspeakers for saving space are mainly of a type having a diaphragm at the forefront, and when the diaphragm appears on the surface, the appearance of the speaker is reduced. The interior and design were poor. In addition, attaching a net or a metal surface mount to the surface increases the thickness and weight of the speaker system, which is against the purpose of reducing the thickness and weight of the speaker system. Therefore, an object of the present invention is to detachably fix a desired image body on the outer surface of the speaker body,
Further, it is an object of the present invention to provide a speaker system which can be easily removed and replaced, and has high interior and design characteristics.

[0004]

The above object is achieved by the present invention described below. That is, the present invention provides a speaker system characterized in that an image body is provided with a removable portion on the outer surface of the speaker body. ADVANTAGE OF THE INVENTION According to this invention, a favorite image body can be detachably fixed to the outer surface of a speaker main body, and it can also be easily removed and replaced, and the speaker system with high interior characteristics and design can be provided. it can.

[0005]

Next, the present invention will be described in more detail with reference to preferred embodiments. In the present invention, as a method of detachably fixing the image body to the outer surface of the speaker main body, for example, a method of detachably fixing the image body via an adhesive layer or an adhesion layer, or providing a fitting portion of the image body A method for fixing the detachable image body is not limited to the shape of the outer surface of the speaker, and the outer surface of the speaker may be flat or curved.

For example, for a speaker having a flat outer surface as shown in FIG. 1, if the outer surface has a curved surface as shown in FIGS. 4 and 5, an image is formed along the curved surface. By providing a removable part where the body can be removed,
The image body can be fixed directly to the outer surface. Alternatively, a mounting plate that does not impair the original acoustic characteristics of the speaker may be provided on the outer surface, and the mounting plate may be used as the outer surface, and the image body may be fixed thereon.

For the adhesive layer used in the present invention, a pressure-sensitive adhesive such as a rubber, an alkyl acrylate polymer or a polyester to which a tackifier has been added, which has been conventionally used for an adhesive tape or the like, may be used. it can. As a method of providing an adhesive layer using the above-mentioned adhesive, a method of applying an adhesive on release paper, providing an adhesive body (tape), and affixing on the outer surface, or directly bonding on the outer surface A method of applying and drying the agent may be used. What is important here is that the adhesive layer maintains the adhesive strength necessary for fixing the image body, and is removable from the image body by controlling the adhesive force. These adhesive layers may be formed on the outer surface side of the speaker or on the back surface of the image body. The formation of the adhesive layer may be performed over the entire back surface of the image body, or the adhesive layer may be provided on a part of the image body such as an end portion or four corners.

In addition to the adhesive layer utilizing the adhesive force of the adhesive as described above, in the speaker system of the present invention, a large number of fine suction cups are formed on the outer surface of the speaker, or irregularities made of foamed resin are provided. May be used as an adhesion layer, and the image body may be pressed against the adhesion layer and fixed. Here, the adhesion can be enhanced by providing the adhesion layer as wide as possible with respect to the image body to be fixed. A device utilizing such close contact is less likely to be repeatedly attached and detached and a decrease in adhesive force due to dust and dirt than a case where an adhesive is used, and is suitable for a case where bonding and peeling are repeated over a long period of time. These adhesion layers may be formed on the back side of the image body.

It is preferable that the image body is directly fixed to the outer surface of the speaker as a decorative part, but this is not the case when the image body is to be attached to a conventional speaker having a speaker net on the outermost surface. Alternatively, an image layer may be attached by providing an adhesive layer, a mounting portion, and the like on the speaker net in the same manner as described above.

It is known to use a piezoelectric element to reduce the thickness of a speaker, and it is possible to reduce the thickness of the speaker by making the diaphragm a planar shape instead of a cone shape. As the material of the diaphragm here, conventionally, polymer materials such as foamed resin, metals, ceramics, papers, nonwoven fabrics and the like can be used. In the present invention, the speaker is made thinner and lighter by directly fixing the image body to the diaphragm. In this case, the image body is as light as possible with respect to the material of the diaphragm, and is fixed by attaching a thin one so that the weight of the image body does not impair the function as the diaphragm and is appropriate.

[0011] The flat speaker to which the present invention is applied is:
The depth is 1 mm to 200 mm, preferably 100 mm or less. If it is more than this, it will not be very suitable for space saving, and if it is 1 mm or less, it will be difficult to have the original functions of the speaker such as volume and sound, so it is not appropriate.

Various types of image bodies to be pasted on the adhesive can be selected, and by fixing or pasting a desired image body, various factors such as brightness, color, atmosphere, etc. of a place where a speaker is installed can be obtained. It is possible to coordinate on your own depending on the environment.

As the image body used in the present invention, various selections such as a silver halide photograph, a photograph such as a publication and a printed matter, a poster, a color copy, and a drawing can be made. The image body can be freely selected depending on the size of the speaker and the purpose of the decoration. However, if it is desired to fix a color image of A5 size or larger on the outer surface of the speaker, the image body printed by a low-cost inkjet printer can be used. Is preferred.

The recording medium on which an image is formed by the ink jet method may be appropriately selected from plain paper, coated paper provided with a special ink receiving layer, glossy paper, glossy film, or the like according to the purpose. Various selections such as color, sharpness, and texture of the image are possible. For example, a glossy film is suitable as a recording medium when it is not affected by ambient temperature and humidity or when high glossiness is required.

The speaker system of the present invention can be used as a wall-mounted type or a stand type by utilizing a flat type or a thin type. As described above, by detachably fixing the image body on the outer surface of the speaker, a speaker system having a desired decorative property can be easily obtained.
