Piezoelectric acoustic component

A piezoelectric acoustic component comprising:

• a vibration body including a substantially rectangular piezoelectric plate having a first major surface and a second major surface, a first vibration body electrode provided on the first major surface of the piezgelectric plate and a substantially rectangular metallic plate provided on the second major surface of the piezoelectric plate;
• a mounting substrate including a first circuit electrode and a second circuit electrode disposed thereon, the first circuit electrode being connected to the metallic plate, the second circuit electrode being connected to the first vibration body electrode;
• support members being arranged such that the vibration body is mounted on the mounting substrate at longitudinal opposite end portions thereof via the support members such that a gap is defined between the mounting substrate and the longitudinal opposite end portions of the vibration body;
• an elastic sealing material sealing the gap between the mounting substrate and each of lateral opposite end portions of the vibration body to thereby define an acoustic space between the vibration body and the mounting substrate;
• and
• a cover having a sound release hole provided therein and which is bonded onto the mounting substrate so as to cover the vibration body without the cover contacting the vibration body.
