A sound output device comprising a dual speaker including a dynamic speaker and a piezoelectric speaker comprising:
- a housing having a housing space therein;
- a dynamic speaker provided inside the housing;
- and
- a piezoelectric speaker provided inside the housing and spaced a predetermined distance from the dynamic speaker;
- wherein the piezoelectric speaker comprises a plate-shaped piezoelectric device and a plate-shaped vibration device provided on one surface of the piezoelectric device and having the same thickness over the entire area thereof,
- wherein the housing which comprises a first member and at least one second member surrounding the first member and of which at least a portion surrounds a spaced space between the dynamic speaker and the piezoelectric speaker,
- wherein the first member has a shape of a plate blocking the dynamic speaker from the piezoelectric speaker to separate the dynamic speaker and the piezoelectric speaker so that sounds emitted from the dynamic speaker and the piezoelectric speaker, respectively, are not mixed;
- and
- wherein a sound output from the dynamic speaker is emitted through an emission hole formed in at least a predetermined region of the housing.
