Abstract:
A mobile terminal according to the present disclosure includes a housing member with a first sound hole, a film speaker and a speaker holder with a second sound hole. The film speaker includes a piezoelectric element and a resin film configured to vibrate with the piezoelectric element. The film speaker is located in the speaker holder. The second sound hole corresponds to the first sound hole and is located between the first sound hole and the film speaker. An inner edge which defines the second sound hole extends above the film speaker. A surface of the inner edge facing the film speaker is inclined such that at least a part of the inner edge decreases in thickness toward a leading end of the inner edge.
