Flexible resonance unit for a speaker
A resonance device for a speaker is provided. The device includes a speaker unit and a resonance unit. The speaker unit outputs a sound corresponding to a signal. The resonance unit is fixed to the speaker unit to provide a space for allowing a sound to resonate. The resonance unit is flexible, and the space for allowing a sound to resonate is variable.
1. An electronic device comprising:
a case frame defining an outer surface of an electronic device and including an outlet;
a main board disposed inside the case frame and including a plurality of electronic components mounted thereon; and
a speaker resonance device disposed between the case frame and the main board,
wherein the speaker resonance device comprises:
a speaker unit disposed on the outlet of the case frame and connected to the main board to output a sound corresponding to a signal from the main board; and
a flexible film fixed to the speaker unit to provide a space for allowing a sound to resonate,
wherein the flexible film occupies at least part of a space between the case frame and the main board.
2. The device of claim 1 , wherein the flexible film has elasticity.
3. The device of claim 1 , wherein the speaker unit comprises at least one vent hole for communication between the space for allowing the sound to resonate and an external space.
4. The device of claim 3 , wherein the vent hole is sealed.
5. The device of claim 1 , further comprising a fixing member for coupling the speaker unit to the flexible film, wherein the fixing member is fixed on the outlet of the case frame.
6. The device of claim 5 , wherein the fixing member includes an opening, the speaker unit is seated on an upper portion of the opening of the fixing member, and the flexible film is attached on a lower portion of the opening of the fixing unit, so that the opening of the fixing member forms an additional space for allowing a sound to resonate.
7. The device of claim 6 , wherein the fixing member comprises at least one vent hole for communication between the space for allowing a sound to resonate and an external space.
8. The device of claim 7 , wherein the speaker unit is attached on an upper portion of the opening of the fixing member with at least one of a sealing member and a buffering member interposed.
9. The device if claim 7 , wherein the vent hole is sealed.
10. The device of claim 6 , wherein one of the speaker unit and the flexible film is attached on the opening of the fixing member using an adhesive.
11. The device of claim 10 , wherein the adhesive includes one of silicon, a spray adhesive, and an epoxy adhesive.
12. The device of claim 1 , wherein the flexible film is attached on the speaker unit using an adhesive.
13. The device of claim 1 , wherein the flexible film is made of at least one material capable of blocking at least one of electricity, light, and heat.
14. The device of claim 1 , wherein the flexible film includes rubber.
