Speaker components

Abstract

This utility model discloses a loudspeaker assembly, which includes a housing, a loudspeaker unit, and an electromagnetic bandgap structure. The housing has a receiving cavity, an antenna is mounted on the housing, the loudspeaker unit is disposed within the receiving cavity, and the electromagnetic bandgap structure is located between the antenna and the loudspeaker unit. Thus, the loudspeaker assembly integrates the loudspeaker unit and the antenna, while the electromagnetic bandgap structure helps improve antenna performance.

Claims

1. A loudspeaker assembly, comprising: A housing having a receiving cavity inside, and an antenna on the housing; a speaker unit disposed within the receiving cavity; And an electromagnetic bandgap structure located between the antenna and the loudspeaker unit, the electromagnetic bandgap structure including a dielectric substrate and a metal pattern disposed on the dielectric substrate.

2. The speaker assembly as claimed in claim 1, wherein, The electromagnetic bandgap structure includes: an outer frame structure with a perforation in the middle; and an inner connection structure located within the perforation and connected to the outer frame structure.

3. The speaker assembly as claimed in claim 2, wherein, The outer frame structure has a first end and a second end, with a first notch formed between the first end and the second end; the inner structure is connected to the first end.

4. The speaker assembly as claimed in claim 3, wherein, The size of the first end is larger than that of the second end.

5. The speaker assembly as claimed in claim 2, wherein, The internal structure includes: a main body portion connected to the outer frame structure; and a protrusion portion that arches out from the main body portion toward the speaker unit.

6. The speaker assembly as claimed in claim 5, wherein, The protrusion includes a first protrusion and a second protrusion, with a second notch formed between the first protrusion and the second protrusion.

7. The speaker assembly as claimed in claim 5, wherein, The outer casing arches within the cavity to form a protrusion; the main body abuts against the protrusion, the protrusion abuts against the speaker unit, and the outer frame structure is suspended.

8. The speaker assembly as claimed in claim 7, wherein, A first gasket is provided between the boss and the main body, and a second gasket is provided between the protrusion and the speaker unit.

9. The speaker assembly as claimed in claim 2, wherein, The first side of the outer frame structure is connected to the housing, the second side of the outer frame structure is connected to the speaker unit, and the inner structure is suspended.

10. The speaker assembly as claimed in claim 1, wherein, These electromagnetic bandgap structural components are symmetrically distributed and spaced apart from each other.

11. The speaker assembly as claimed in claim 1, wherein, The electromagnetic bandgap structure is spaced apart from the antenna.

12. The speaker assembly as claimed in claim 1, wherein, The housing includes: a first housing having the antenna thereon; and a second housing mating with the first housing to form the receiving cavity.

13. The speaker assembly as claimed in claim 12, wherein, The second housing has a through hole that connects to the receiving cavity; the speaker unit is exposed through the through hole.

14. The speaker assembly as claimed in claim 13, wherein, The second housing has a base at the edge of the through hole; the speaker unit abuts against the base and closes the through hole.

15. The speaker assembly as claimed in claim 1, wherein, The antenna is directly molded onto the housing using laser technology.

16. The speaker assembly as claimed in claim 1, wherein, This electromagnetic bandgap structure is a metamaterial structure.
