Loudspeaker bracket
A bracket for attachment to a first speaker and for suspending a second speaker therefrom. The bracket comprises a suspension member configured for attachment to a second speaker and defining an axis about which a second speaker is free to rotate when attached to the suspension member and an adjustable end stop configured to limit the maximum amount of rotation of a second speaker about the axis of rotation.
1. A bracket for attachment to a first speaker and for suspending a second speaker therefrom, the bracket comprising:
a suspension member configured for attachment to the second speaker; and
a partial trunnion that defines an axis of rotation about which the second speaker is free to rotate when attached to the suspension member, wherein the axis of rotation is outside a boundary of the partial trunnion and the axis of rotation is substantially between the first speaker and the second speaker, and wherein the suspension member comprises two connection arms, each connectable to the second speaker and configured to cooperate with a surface of the partial trunnion to allow the second speaker to rotate freely about the axis of rotation.
2. The bracket according to claim 1 , wherein the suspension member comprises two connection arms rotatable about a fulcrum.
3. The bracket according to claim 2 , wherein the connection arms are rigidly connected.
4. The bracket according to claim 2 , wherein the fulcrum comprises a trunnion that includes the partial trunnion, and wherein a surface of the connection arms is shaped to cooperate with a surface of the trunnion to allow a second speaker to rotate freely about the axis of rotation when attached to the suspension member.
5. The bracket according to claim 1 , wherein the end stop is configured to limit rotation of a second speaker suspended from the suspension member when rotated by application of a force, the end stop being further configured to allow the second speaker to return to an equilibrium suspended state when the force is removed.
6. The bracket according to claim 1 , wherein the suspension member further comprises an end stop arm configured to move towards the end stop on rotation of a second speaker suspended from the suspension member and engage with the end stop to limit rotation of the second speaker.
7. The bracket according to claim 6 , wherein the end stop arm extends perpendicular to the axis of rotation.
8. The bracket according to claim 2 , further comprising an end stop arm configured to move towards the end stop on rotation of a second speaker suspended from the suspension member and engage with the end stop to limit rotation of the second speaker, wherein the connection arms and the end stop arm substantially form the shape of a lambda.
9. The bracket according to claim 6 , wherein the adjustable end stop is rotatable to present one of a plurality of end stop faces to the end stop arm, wherein each of the plurality of end stop faces defines a different maximum amount of rotation of the second speaker.
10. The bracket according to claim 9 , wherein the adjustable end stop comprises a rotatable cam shaped member, and wherein the end stop faces are arranged around an outer edge of the cam shaped member.
11. The bracket according to claim 9 , wherein the plurality of end stop faces are configured such that, when the end stop arm is engaged with an end stop face, a force applied by the end stop arm on the end stop face is directed through an axis of rotation of the adjustable end stop.
12. The bracket according to claim 1 , further comprising a frame housing the suspension member and attachable to a sidewall of a speaker enclosure of a first speaker, and wherein the suspension member is moveable between a retracted position within the frame and an extended position at which the suspension member is attachable to the second speaker.
13. The bracket according to claim 1 , wherein the axis of rotation is substantially equidistant between the first speaker and the second speaker.
14. A speaker comprising an audio driver, a speaker enclosure and a bracket attached to a sidewall of the speaker enclosure, the bracket comprising:
a suspension member configured for attachment to a second speaker; and
a partial trunnion that defines an axis of rotation about which the second speaker is free to rotate when attached to the suspension member, wherein the axis of rotation is outside a boundary of the partial trunnion and the axis of rotation is substantially between the speaker and the second speaker,
and wherein the suspension member comprises two connection arms, each connectable to the second speaker and configured to cooperate with a surface of the partial trunnion to allow the second speaker to rotate freely about the axis of rotation.
15. A speaker column comprising a plurality of speakers, wherein a plurality of speakers are suspended from a preceding speaker in the column, and wherein each of the plurality of speakers comprises an audio driver, a speaker enclosure and a bracket attached to a sidewall of the speaker enclosure, the bracket comprising:
a suspension member configured for attachment to a second speaker; and
a partial trunnion that defines an axis of rotation about which the second speaker is free to rotate when attached to the suspension member, wherein the axis of rotation is outside a boundary of the partial trunnion and the axis of rotation is substantially between a first speaker and the second speaker,
and wherein the suspension member comprises two connection arms, each connectable to the second speaker and configured to cooperate with a surface of the partial trunnion to allow the second speaker to rotate freely about the axis of rotation.
