Sound output assembly
A sound output assembly includes an enclosure, a speaker assembly disposed inside the enclosure, and a supporting member having at least a first end fixed to the enclosure such that the at least the first end of the supporting member and the enclosure are formed as one body. The speaker assembly includes an acoustic diaphragm configured to produce a sound by vibrating in accordance with a sound signal. The supporting member is configured to support the speaker assembly and to dampen vibration of the speaker assembly.
1. A sound output assembly comprising:
an enclosure configured to be detachably mountable to an automobile;
a speaker assembly disposed inside the enclosure;
a supporting member having at least a first end fixed to the enclosure such that the at least the first end of the supporting member and the enclosure are formed as one body; and
a sealing member connected to the supporting member,
wherein:
the speaker assembly includes an acoustic diaphragm configured to produce a sound by vibrating in accordance with a sound signal,
the supporting member has a beam structure, includes at least one bent portion, and is configured to support the speaker assembly and to dampen vibration of the speaker assembly,
the enclosure has an opening disposed at a position that corresponds to the acoustic diaphragm, and
the sealing member and a portion of the supporting member together seal a gap between a peripheral edge of the opening and the speaker assembly.
2. The sound output assembly according to claim 1 , further comprising a vibration absorber configured to absorb vibration being transmitted from the speaker assembly to the enclosure,
wherein the enclosure includes:
a first member having the opening disposed at the position that corresponds to the acoustic diaphragm; and
a second member disposed apart from the first member,
wherein the speaker assembly is disposed between the first member of the enclosure and the second member of the enclosure, and
wherein the vibration absorber is disposed between the second member of the enclosure and the speaker assembly.
3. The sound output assembly according to claim 1 , wherein the at least the first end of the supporting member and the enclosure are formed as one body by the at least the first end of the supporting member being welded to the enclosure.
4. The sound output assembly according to claim 1 , wherein the at least the first end of the supporting member and the enclosure are formed as one body by the at least the first end of the supporting member being integrally formed with the enclosure.
5. The sound output assembly according to claim 1 , wherein the at least one bent portion has a squared U-shape.
6. A sound output assembly comprising:
an enclosure;
a speaker assembly disposed inside the enclosure; and
a supporting member having a main portion, a first junction connected to the main portion and to a first side face of the enclosure, and a second junction connected to the main portion and to a second side face of the enclosure different from the first side face of the enclosure,
wherein:
the speaker assembly includes an acoustic diaphragm configured to produce a sound by vibrating in accordance with a sound signal,
the supporting member is configured to support the speaker assembly by the main portion of the supporting member and to dampen vibration of the speaker assembly by elastic deformation of the first junction and the second junction, and
the first junction includes a first bent portion, and the second junction includes a second bent portion.
7. The sound output assembly according to claim 6 , wherein the first bent portion has a squared U-shape, and the second bent portion has a squared U-shape.
8. The sound output assembly according to claim 6 , wherein the first side face of the enclosure and the second side face of the enclosure are disposed on opposite sides of the enclosure from each other.
9. The sound output assembly according to claim 6 , wherein the supporting member further includes (i) a third junction separated from the first junction and connected to the main portion and to the first side face of the enclosure and (ii) a fourth junction separated from the second junction and connected to the main portion and to the second side face of the enclosure.
10. The sound output assembly according to claim 9 , wherein the third junction includes a third bent portion, and the fourth junction includes a fourth bent portion.
11. A sound output assembly comprising:
an enclosure;
a speaker assembly disposed inside the enclosure; and
a supporting member having a main portion, a first junction connected to the main portion and to a first side face of the enclosure, and a second junction connected to the main portion and to a second side face of the enclosure different from the first side face of the enclosure,
wherein:
the speaker assembly includes an acoustic diaphragm configured to produce a sound by vibrating in accordance with a sound signal,
the supporting member is configured to support the speaker assembly by the main portion of the supporting member and to dampen vibration of the speaker assembly by elastic deformation of the first junction and the second junction,
the supporting member further includes (i) a third junction separated from the first junction and connected to the main portion and to the first side face of the enclosure and (ii) a fourth junction separated from the second junction and connected to the main portion and to the second side face of the enclosure, and
wherein the first junction and the third junction are substantially parallel to each other, and the second junction and the fourth junction are substantially parallel to each other.
