Description

  The present invention relates to a megaphone used for supporting sports competitions, and more particularly to a string attachment that can be attached to a megaphone body to be strapped on a hand or suspended from a neck.

  Megaphones that are actively used for support of sports competitions such as baseball are not only to raise the voice of support, but also to support the sound with the sound of hitting by hitting a plastic megaphone such as polyethylene . A string is usually attached to such a plastic megaphone. In many cases, two megaphones are connected with a string, hung from the neck, and the two megaphones are struck to support each other.

  Usually, a string is attached to a plastic megaphone by providing a protruding part with a string passage hole near the boundary between the mouth part and the loudspeaker part of the megaphone, and tying the hole through the string, or connecting the megaphone tube near the mouth part. It is performed by providing a hole in the body and attaching the string through the hole through the hole (see, for example, Patent Document 1).

  However, since the support is performed by grasping the boundary portion between the mouth portion and the loudspeaker portion of the megaphone, if there is a protruding portion for attaching a string near the boundary portion, the user feels uncomfortable when holding the megaphone. Also, if the megaphone body is provided with a string hole, the appearance is not good just because the string is attached, and the saliva of the person who blows the voice into the megaphone moves to the string and may wet the string. It was. In order to solve such a problem, there has also been proposed a megaphone in which a string-through tube for connecting a string-through hole is provided inside the mouth portion (blow-off port) and the string is passed through the tube (see Patent Document 2). . Providing such a tube that traverses the megaphone body is not preferable because the method of forming the megaphone becomes complicated and the manufacturing cost increases.

  As described above, there is no megaphone with a support string that can be easily attached at the time of manufacture, has a good appearance and is excellent in design, and such a megaphone has been desired.
