代替して口当て部分２を装着する。 Regarding the structure of the present invention, the external size of the silencer 1 is approximately 20 cm in length, approximately 8 cm in diameter, and has a cylindrical shape. It can be filled with a sound absorbing material such as woven wool. In the case of a muffler-like muffler for a car, as shown in FIGS. 1 and 2, a large number of small chambers D are installed in the middle of the sound hole. In the direction of the arrow in Fig. 1, the human voice first passes through the first stage audio passage hole A in the center, reverses when it hits the front wall, and flows back through the second stage audio passage hole B in the upper and lower parts. There, it hits the wall again and turns around, passing through the third stage audio passage hole C on the left and right as shown in Figure 2.
Head to exit cap 3. The sound wave energy is reduced by letting human voices flow into a number of small rooms D along the way. The audio passage holes A, B, and C have a rectangular shape as shown in FIG. The diameter of the part of the mouthpiece part 2 that touches the mouth is about 5.5cm, and both sides are deformed so that it can fit easily around the mouth. On the part that touches your mouth,
An air purifying filter 4a is attached to the transmitting part of the telephone. The inside of the mouthpiece part 2 is filled with activated carbon 5 wrapped in paper. The mouthpiece part 2 and the silencer 1 are attached with screws. An outlet cap 3 is attached to the outlet side of the silencer 1 with screws. An air purifying filter 4b is installed inside the outlet cap 3. In the case of a sound damping device filled with sound absorbing material, the exhaled air is made to flow in the direction of the arrow as shown in FIG. In the case of a two-way silent conversation hand speaker as claimed in claim 2 of the utility model registration, a mouthpiece portion 2 is attached in place of the exit cap 3.

怒嗚り合うことも可能となる。 Regarding the effects of the present invention, modern people have more and more opportunities to speak out loud. Companies, especially sales departments, conduct training on how to speak out loud in order to raise their spirits. Speaking out loud is also necessary to relieve stress. There are many opportunities for loud vocalization, such as karaoke singing practice, husband and wife fights, etc.

The present invention aims to solve the above-mentioned difficulties and contribute to mental stability by making it possible to speak out loud without worrying about people around you. The silent hand speaker with two-way silent dialogue can be used in coffee shops, bars,
It is also effective for a private conversation between two people without being overheard by others in a club, etc., or during business negotiations, etc., and allows both parties to take turns yelling at each other without hesitation.
