A sound generator 30 includes a piezoelectric element 1, a vibrating body 3a, a reflection member 81, a reflection member 82, an opening 21, and an opening 22. The vibrating body 3a vibrates due to vibration of the piezoelectric element 1 and generates a sound. The reflection member 81 is disposed in a first direction from the vibrating body 3a so as to be inclined with respect to the vibrating body 3a. The reflection member 82 is disposed in a second direction, which is opposite to the first direction, from the vibrating body 3a so as to face the reflection member 81 with the vibrating body 3a therebetween and so as to be inclined with respect to the vibrating body 3a. The opening 21 faces in a third direction. The opening 22 faces in a fourth direction, which is different from the third direction.
