Abstract

PURPOSE:To easily and strongly fit a speaker net 4 to a front face of a speaker enclosure 1 with simple configuration in the structure to fit the speaker net 4 to the front face of the speaker enclosure 1. CONSTITUTION:Projection poles 7 are provided to a speaker net 4 and holes 8 to which the projection poles 7 are press fit in a twisted state are provided to a speaker enclosure 1. While the projection poles 7 are press-fit to the holes 8, the fitting state of the holes 8 is strongly maintained by the torsional elasticity of the projection poles thereby allowing the speaker net 4 to be surely fixed to the speaker enclosure 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a speaker net on the front surface of a speaker enclosure in a speaker device.

[0002]

2. Description of the Related Art Generally, in a speaker device, a speaker net for protecting the speaker is attached to the front surface (speaker exposed surface) of a speaker enclosure in which the speaker is attached. As a conventional mounting structure for this speaker net, a round pin is provided at a plurality of locations on the speaker net side, and correspondingly, a hole portion (bag boss) is provided on the speaker enclosure side, and the round pin is provided in this hole portion. The speaker net is fixedly attached to the speaker enclosure by press-fitting into the speaker enclosure. For non-detachable speaker nets, the speaker net is fixed with screws from the back side of the speaker enclosure.

[0003]

In the conventional speaker net mounting structure as described above, in the former case, the fixing strength of the speaker net and the speaker enclosure depends on the dimensional accuracy of the round pin and the hole portion, so that a reliable fixing is achieved. In the latter case, it is necessary to disassemble the speaker enclosure when removing the speaker net for maintenance, and the latter case has the disadvantage of poor serviceability.

The present invention has been made in view of the above points,
An object of the present invention is to provide a structure capable of securely fixing a speaker net to a speaker enclosure and easily removing the speaker net without disassembling the speaker enclosure during maintenance.

[0005]

In order to achieve the above object, the present invention has a structure for mounting a speaker net on the front surface of a speaker enclosure, for example, a cross section made of an elastic material on the speaker net side. In addition to providing a radial projecting pillar, a hole portion into which the projecting pillar is press-fitted in a twisted state is provided on the speaker enclosure side, and the torsional elasticity of the projecting pillar allows the fitting and fixing state to the hole portion to be maintained. It was done.

[0006]

As described above, according to the structure of the present invention, when the projecting column is press-fitted into the hole, the fitting and fixing state is maintained by the torsional elasticity of the projecting column, so that the speaker net is securely fixed to the speaker enclosure. Further, when the speaker net is removed during maintenance, the speaker net is easily removed from the speaker enclosure by pulling out the protruding column from the hole against the fitting force due to the torsional elasticity of the protrusion.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of the present invention.
FIG. 1 shows the overall configuration of a speaker device to which the present invention is applied. In the figure, 1 is a speaker enclosure, and a speaker 3 is attached to the speaker enclosure 1 so as to be exposed from an opening 2 on the front surface.
And on the front of this speaker enclosure 1,
A speaker net 4 for protecting the speaker 3 is attached.

As shown in FIG. 2, the speaker net 4 is constructed by covering the front side of the frame body 5 with the net 6, and on the rear side of the frame body 5, two upper and lower nets are provided in total. Four projecting pillars 7 are erected. This projecting pillar 7 is a plastic (for example, HI-PS) having elasticity integrally with the frame body 5.
The cross section is formed in a radial shape in which ribs 7a, 7b, 7c project in three directions. On the other hand, a triangular hole portion (bag boss) 8 facing the cross-sectional shape of the projecting pillar 7 is provided in the front surface portion of the speaker enclosure 1 corresponding to each of these projecting pillars 7. On the pillar 7
The speaker net 4 is attached to the speaker enclosure 1 by press-fitting and fitting.

In this arrangement, the positional relationship between the projecting pillar 7 and the hole portion 8 is such that the front edge portions of the ribs 7a, 7b, 7c of the projecting pillar 7 interfere with the hole portion 8 as shown in FIG. However, after the press-fitting, the projecting pillar 7 is fitted into the inner surface of the hole 8 in a twisted state as shown in FIG. In this case, in order to allow the projecting pillar 7 to be smoothly press-fitted into the hole 8 and twisted, the projecting pillar 7 is tapered in the present embodiment as a whole to be tapered toward the tip.

As is apparent from the above structure, in the speaker device of this embodiment, when the projecting pillar 7 is press-fitted into the hole 8, the projecting pillar 7 is fitted in the hole 8 in a twisted state. Due to the torsional elasticity of the column 7, the fitting state of the projecting column 7 and the hole 8 is firmly maintained, and therefore the speaker net 4 is securely fixed to the speaker enclosure. Also, when removing the speaker net 4 during maintenance, pull out the projecting column 7 from the hole 8 by applying a required force (a force stronger than the fitting force due to the torsional elasticity of the projecting column 7) to the speaker net 4 by hand. Thus, the speaker net 4 is easily removed from the speaker enclosure 1.

FIG. 5 and FIG. 6 show a second embodiment, that is, in this example, contrary to the first embodiment, the projecting column 7 is formed into a hole 8 by tapering the hole 8 side. The protrusion 7 is made to have torsional elasticity when it is pressed into.

FIG. 7 shows a third embodiment, that is, in this example, ribs 7a, 7b, 7 are formed on the cross section of the projecting pillar 7 in all directions.
It is formed in a cross-shaped radial shape in which c and 7d project. In this case, the hole portion 8 into which the projecting pillar 7 is press-fitted is formed in a quadrangular shape that faces the cross-sectional shape of the projecting pillar 7.

In the second and third embodiments as well, similar to the first embodiment, when the projecting pillar 7 is press-fitted into the hole 8, the projecting pillar 7 and the hole are caused by the torsional elasticity of the projecting pillar 7. 8
The fitting state of is firmly maintained. The strength (tightness) of the fitting between the projecting pillar 7 and the hole 8 depends on the length, the thickness, the number of ribs, the taper angle of the projecting pillar 7, and the hole portion facing the projecting pillar 7. The depth and taper angle of 8 and the amount of overlap between the projecting column 7 and the hole 8 can be set delicately.

Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of these embodiments. For example, the projecting pillar 7 is not limited to the cross-sectional shape shown in the embodiment, but may be any shape as long as it has a radial shape so that torsional elasticity can be obtained in a state of being press-fitted into the hole 8. Further, in the embodiment, the projecting pillar 7 is provided on the speaker net 4 side and the hole portion 8 is provided on the speaker enclosure 1 side. However, this configuration is reversed, that is, the projecting pillar 7 is provided on the speaker enclosure 1 side, and the speaker net 4 is formed. The same effect can be obtained even if the hole 8 is provided on the side. Further, the speaker enclosure 1 is not limited to a speaker only, but includes a case where it is a part of an audio device having a sound source.

[0015]

As described above, according to the present invention,
Since the fitting state with the hole is firmly maintained by the torsional elasticity of the projecting column when the projecting column is press-fitted into the hole, the speaker net can be securely fixed to the speaker enclosure. In addition, at the time of maintenance, the speaker net can be removed without disassembling the speaker enclosure, which enables easy and quick service.
