Description

[Detailed description of the invention] The present invention relates to a speaker grill plate, which includes a net having appropriate rigidity that is bent into an arbitrary shape.
To provide a speaker grill plate which can be easily and reliably attached to a speaker body without causing wrinkles or looseness or unraveling.

In general, the speaker grille plate attached to the front of the speaker body is made by tensioning and fixing something woven from cloth or synthetic resin yarn, such as saran net, to a frame-shaped outer frame made of wood or synthetic resin. something is known.

FIG. 1 is a perspective view showing a speaker grill plate attached to the front surface of a conventional speaker body. In the figure, 1 is an outer frame, 2 is a Saran net, 3 is a reinforcing crosspiece of the outer frame 1, 6 is a fixing bracket for attaching the Saran net 2 to the outer frame 1, 7 is provided at the four corners of the back of the outer frame 1, Projections 8 for removably attaching the speaker grill plate to the speaker body 9 are mounting holes provided at four corners of the front surface of the speaker body 9 into which the projections 7 are fitted.

In the conventional speaker grill plate having such a structure, the Saran net 2 is fixed to the outer frame 1 under tension with the fixing fittings 6 over the entire circumference. There were drawbacks such as looseness such as wrinkles in No. 2 and unraveling. In addition, the number of parts inevitably increases, and advanced processing technology is required in terms of assembly man-hours and dimensional accuracy.Furthermore, from the perspective of the strength of the speaker grill plate, the thickness of the outer frame 1 and reinforcing crosspiece 3 ,
Since the width and other parameters are automatically limited, there is an inconvenience that the sound shielding area increases and the acoustic efficiency decreases. In addition, the outer shape of the Saran Net 2 cannot be formed into any arbitrary shape such as a curved surface or an uneven surface, and is limited to a simple planar shape. The drawback was that it could not be done.

The present invention was devised to eliminate the above-mentioned drawbacks, and involves bending a net made of metal, synthetic resin, etc. and having appropriate rigidity into an arbitrary shape. A cover member attached to cover the outer peripheral end is provided, and the cover member is provided with a mounting member for attaching the net to the speaker body, whereby the outer shape of the net can be arbitrarily bent. It is an object of the present invention to provide a speaker grille plate having a robust structure which can be formed into a net structure having a shape and which allows the net to be easily and securely attached to a speaker body without causing wrinkles or looseness or unraveling. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 2 is an exploded perspective view of a speaker grill plate according to an embodiment of the present invention, and Figs. 3 to 7 are partially enlarged explanatory views of the speaker grill plate shown in Fig. 2, showing the same parts as Fig. 1. are indicated using the same reference numerals, and detailed explanation thereof will be omitted. As shown in the above figures, 4 is a cover member made of metal or synthetic resin, which is the main component of the present invention, and 5 is a reinforcing bar 3.
6a is a mounting screw, 10 is a fixing screw hole drilled in cover member 4, and is used to integrally attach this to net 2a together with reinforcing bar 3a; 7; are protrusions similar to those shown in FIG. 1 provided at both ends of the back surface of the cover member 4. As shown in FIGS. 2 to 7, the speaker grill plate of the present invention is produced by bending a net 2a made of metal, synthetic resin, etc. and having appropriate rigidity into an arbitrary external shape. Two covering members 4 are provided to cover both upper and lower ends of the outer periphery of the net 2a, and the net 2a is sandwiched between each of these covering members 4 and a reinforcing bar 3a, and the net 2a is integrally tightened with mounting screws 6a. As a result, the speaker grill plate can be assembled and configured easily.

As detailed above, the speaker grill plate according to the present invention is made by bending a net having appropriate rigidity made of metal, synthetic resin, etc. into an arbitrary external shape,
2 on the upper and lower ends of the outer circumference of this bent net
Since it has a structure in which each covering member is covered with each other, and each covering member is integrally tightened and fixed together with the net and reinforcing bar using mounting screws, there is no need to worry about the wrinkles of the net, looseness, or unraveling. It can be resolved. In addition, since the covering member can be made of metal or synthetic resin, it has the effect of reinforcing the speaker grill plate, and since there is no need for a frame-shaped outer frame, reinforcing bars, etc. as in the conventional example, the overall It has the advantage that it can be formed extremely thin, and the acoustic shielding area can be made as small as possible, allowing it to be used as a highly efficient speaker grill plate. Furthermore, compared to conventional products of this type, the number of parts can be reduced and assembly man-hours can be simplified, and it can be easily manufactured using processing technology that can easily achieve high dimensional accuracy. Since the external shape of the net can be bent into any shape such as a curved surface or an uneven surface, it is possible to harmonize with the external shape of the net itself and the accented external shape of the covering member attached to the outer peripheral edge of the net. It has particularly excellent effects, including the ability to obtain decorative effects based on the overall shape.
