Disclosed is a speaker-box. The speaker-box includes a case, a speaker unit received in the case and a heat radiating portion attached on the base and directly connecting to a part of the speaker unit for dissipating the heat generated by the speaker unit.
1. A speaker-box comprising:
a case having a base, a cover mounted on the base, and a receiving room formed by the cover together with the base, the base including a through hole;
a speaker unit received in the receiving room, at least a part of the speaker unit being received in the through hole; and
a heat radiating portion attached on the base and physically connecting to the part of the speaker unit received in the through hole for dissipating the heat generated by the speaker unit.
2. The speaker-box as described in claim 1 , wherein the speaker unit has a holder and a magnetic system received in the holder, and at least a part of the magnetic system projects from the holder and is received in the thought hole for directly being connecting to the heat radiating portion via the through hole.
3. The speaker-box as described in claim 2 , wherein the base further has a fixing portion extending toward the cover and surrounding the through hole for fixing the speaker unit on the base firmly.
4. The speaker-box as described in claim 1 , wherein the heat radiating portion has a metal plate inserting in the thought hole and integrated with the base by injection molding and a heat radiating film covered on the metal plate.
5. The speaker-box as described in claim 4 , wherein a part of the heat radiating film is covered on the metal plate for efficiently dissipating the heat and the rest is attached on the second surface for fixing the heat radiating portion on the case firmly.
6. The speaker-box as described in claim 4 , wherein the heat radiating film has a platy portion attached on the metal plate and a pair of extending portions extending from two opposite ends of the platy portion and away from the platy portion for engaging with the cover.
7. The speaker-box as described in claim 1 , wherein the base further has a receiving concave extending from the second surface toward the first surface for receiving the heat radiating portion and the through hole is provided on the receiving concave.
8. The speaker-box as described in claim 1 , wherein the base further has a receiving slot extending from the first surface toward the second surface and surrounding the through hole for filing with an adhesive which is connected with the magnetic system and the heat radiating portion.
