Speaker device

A portable speaker device comprising:

• a speaker unit having a vibration portion;
• and
• an acoustic lens having a surface disposed to face the vibration portion and adapted to reflect an emitted sound from the speaker unit,
• wherein a gap distance between the vibration portion and the surface of the acoustic lens is a distance at which the vibration portion provides a maximum amplitude of the emitted sound to the acoustic lens, and the gap distance is substantially constant.

An electronic device comprising:

• a housing;
• a speaker device disposed inside the housing;
• and
• a sound generation circuit electrically connected to the speaker device,
• wherein the speaker device comprises:
• a sound generation plate movable in a first direction when sound is generated by the sound generation circuit;
• and
• a sound reflection construction facing the sound generation plate to form a space between the sound generation plate and the sound reflection construction,
• wherein the space is in fluidic communication with an exterior of the housing via a plurality of sound holes formed in a outer wall of the housing,
• wherein the sound generation plate comprises a first surface disposed substantially at a center of the sound generation plate, the first surface having a convex shape when viewed from inside the space, and
• wherein the sound reflection construction comprises a second surface substantially aligned with the first surface along an axis of the housing, the second surface having a concave shape when viewed from inside the space.
