摘要： PURPOSE:To provide a sounding body by which resonance space can be enlarged in a small size in the sounding body mountable on a surface. CONSTITUTION:A sounding body has a sounding part 40 of a sounding means where a magnet 7 installed together with a pole piece 8 is fixed inside of a cylindrical cage body 10 formed on a base 4 having a surface mounted terminal 5 and a coil bobbin 17 is installed on the pole piece 8 and which has a vibration plate 19 held by being attracted by the magnet 7, a container 2 to form resonance space on an upper surface of the vibration plate 19 or on a side surface of the cage body 10 by covering an upper surface of the base 4 and a sound release hole 3 formed in this container 2 so as to release a vibration sound by releasing the resonance space to the outside air.
