I took it apart after 10 days. There on the board there is that squeaker (buzzer) and glued it on top. But it turned out too quiet. I tokda in the center pierced with a needle. The squeak turned out to be 70% quieter (soft and thin) than it was. On the lower plastic part inside there is a marking (circle) of the years and month of issue. Mine was made on 08202222, and I bought it on 03202223 like this.
