Description

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

Generally, when driving a motorcycle, the user cannot wear a helmet while wearing a receiver, earphones, etc., and therefore cannot listen to the radio, cheap recorder, radio, etc. while riding.

In addition, in order to listen to the radio while driving, it is necessary to process the helmet 21 itself and attach speakers 22 as shown in Figure 3, which makes the work troublesome and complicated, and increases the cost of the helmet itself. .

In view of the above-mentioned problems, the inventors of the present invention have developed the present invention to effectively solve the problem.The purpose of this invention is to attach a speaker case to the chin strap of a helmet, At the same time, by tying the base end of the sound guide tube to the case and positioning the tip near the ears of the helmet user, the speaker unit can be attached to the helmet itself without any modification to the helmet itself. To provide a speaker for a helmet which can have the same effect as when a speaker is attached.

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. Reference numeral 1 indicates a helmet body made of a hard plastic material, and the inner circumferential wall of this body 1 has a constant thickness. A cushioning material 2 made of a damp sponge material is attached.

One end of a pair of chin straps 3, 3 is fixed to the lower inner surface of the main body 1, and these chin straps 3, 3 are connected via a fastener 4.

A speaker case 5 is attached to the chin strap 3, and the speaker case 5 has a housing 7 in which the speaker unit 6 is housed, and a hole 9 that communicates with the housing 7 through an opening 8. The lower part of the case forming the hole 9 is made to protrude laterally to form an engaging part 10.

The proximal end 11 of the sound guide tube 11 is attached to this engaging portion 10.
A is inserted.

The sound guide tube 11 is made of rubber or soft plastic material, and its length is such that the end portion 11b is located near the ear when a helmet is worn.

The distal end portion 11b is cut diagonally inward so that the opening 11c of the tube 11 faces the ear.

Figure 2 shows another embodiment of the present invention.
A recessed groove 12 is formed in the recessed groove 12, and a sound guide tube is fitted into the recessed groove 12.

By doing this, a sufficient sound volume can be ensured without the sound guide tube 11 being crushed, and since the portion that hits the face is also reduced, there is no discomfort.

The above is just an example of the present invention. In the example shown in Fig. 1, a pair of speakers are installed on the left and right sides, but it is also possible to install only one pair of speakers. Also, to attach the speaker case to the chin strap, a band or surface is required. A 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 chin strap of a helmet, a speaker unit is disposed within this case, and the base end of a sound guide tube is connected to the case. Since the tip is extended close to the ear of the helmet wearer, it achieves the same effect as if the speaker was attached to the helmet itself without having to cover the helmet itself, that is, the sound can be guided close to the ear. Moreover, it has many advantages, such as being able to achieve this without using any special members and by simply attaching the speaker case to the chin strap.
