Description

[Detailed Description of the Invention] The present invention relates to a helmet speaker in which the speaker is attached to the lower edge of the helmet.

Generally, when driving a motorcycle, it is impossible to wear a receiver, earphones, etc. and a helmet, so if you want to listen to the radio, tape recorder, radio, etc. while riding, please use the method shown in Figure 3. It is necessary to process the helmet 21 itself and attach the speaker 22,
For this reason, the installation process is troublesome and complicated, and this also increases the cost of the helmet itself.

The present inventors developed the present invention in view of the above-mentioned problems, and the purpose is to attach a speaker case to the lower edge of the helmet, and arrange the speaker unit within this case. By tying the base end of the sound guide tube to the above-mentioned case and extending the tip end near the ears of the helmet wearer, an effect similar to that of attaching a speaker to the helmet itself can be obtained without any modification to the helmet itself. To provide helmet speakers with:

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a vertical cross-sectional view showing the state of use of a helmet equipped with a speaker according to the present invention, in which 1 is a helmet body made of a hard plastic material, and the inner surface of this body 1 has a certain thickness. Cushioning material 2 made of sponge material
. . , and a liner 3 having a substantially oval cross section is fitted into the lower edge 1a of the main body 1 with a groove.

A speaker case 4 is attached to the liner 3, and a housing 7 for a speaker unit 6 is formed in the base 5 of the speaker case 4, and a clamping piece for clamping the liner 3 is provided from the upper end of the base 5. One side 8 of the helmet body 1 is extended, and the liner 3 is held by tightening this holding piece 8 and the other holding piece 9 with bolts 10, and the speaker case 4 is integrally attached to the lower edge 1a of the helmet body 1. There is.

An opening 11 communicating with the storage section 7 is formed on the side surface of the base 5, and an engaging section 12 having seven run holes projects outward from the opening 11.

The sound guide tube 13 is engaged with the engaging portion 12 with its engaging portion 14 .

The sound guide tube 13 is made of rubber or soft plastic material, and its length is such that the tip 15 is located near the ear of the helmet wearer.

This tip 15 is cut diagonally inward,
The tip opening 16 faces the wearer's ear.

FIG. 2 shows another embodiment of the present invention, in which a concave groove 17 is formed in the cushioning material 2 attached to the inner surface of the helmet, and a sound guide tube 13 is fitted into the concave groove 17. There is.

By doing this, the sound guide tube 13 will not be crushed between the helmet and the wearer's face, ensuring a sufficient volume of sound, and the part of the sound guide tube 13 that comes into contact with the wearer's face will be reduced, so there will be no discomfort. It never occurs.

The above is merely an example of implementing the present invention, and it is possible to provide a pair of speakers on the left and right, or only one of them, and the means for attaching the speaker case to the lower edge of the helmet is not limited to the above. For example, a clip, hook-and-loop fastener, adhesive, or the like may be used.

As is clear from the above description, according to the present invention, a speaker case is attached to the lower edge of the helmet, a speaker unit is disposed within this case, and the base end of the sound guide tube is connected to the case. Furthermore, since the tip of the helmet is extended close to the ears of the helmet wearer, it produces the same effect as if the speakers were attached to the helmet itself, without making any modifications to the helmet, i.e., the sound can be guided close to the ears. , and has many advantages such as being able to achieve this with a simple operation of attaching the speaker case to the lower edge of the helmet with bolts, screws, clips, etc.
