Abstract

A connection of the sound bowl and connecting portion of a loudspeaker is disclosed. The connection area is adhered with the elastic materials similar to the materials of sound bowl and connecting portion in order to beautify the appearance of loudspeaker and enhance the adhesion. Thereby the tolerance of the loudspeaker is enhanced. Thus, the loudspeaker is tolerable to vibration and produces sound with precise tunes, and stabilizes the quality of sound.

Claims

1. A loudspeaker comprising a bowl-shaped sound bowl and an arc-shaped elastic connecting portion;

characterized in that;

the connecting sides of the sound bowl and the connecting portion are connected by thermal-plastic elastomers;

in manufacturing, thermal-plastic elastomer is injected into a mold to connect the connecting portion and the sound bowl at a predetermined temperature.

2. The loudspeaker as claimed in claim 1, wherein the sound bowl and connecting portion are made of hard plastic materials.

3. The loudspeaker as claimed in claim 2, wherein the plastic material is selected from one of a group containing PP and PS.

4. The loudspeaker as claimed in claim 1, wherein connecting sides of the sound bowl and the connecting portion are connected by thermal-plastic elastomer.

5. The loudspeaker as claimed in claim 1, wherein the connecting sides of the sound bowl and connecting portion are flat.

6. The loudspeaker as claimed in claim 1, wherein the connecting side of the sound bowl is engaged with the connecting side of the connecting portion.

7. The loudspeaker as claimed in claim 1, wherein the connecting sides of the sound bowl and the connection portion are punched with holes;

and the thermal plastic material is filled into the holes.

8. A modified structure for loudspeaker as stated in claim 1, the connecting sides of the sound bowl and the connecting portion are folded as a plurality of folds along the peripherys of the edges of the sound bowl ad the connecting portion.
