Waveguide assembly

A waveguide assembly for guiding sound, the waveguide assembly including:

• a chassis that provides a cavity configured to receive sound propagating in a forwards direction along a primary axis of the waveguide assembly;
• a fixed waveguide that is fixed with respect to the chassis and positioned on the primary axis of the waveguide assembly, wherein the fixed waveguide is spaced apart from the chassis and is configured to guide sound received by the cavity through at least one opening formed between the fixed waveguide element and the chassis;
• a moveable waveguide that is moveable with respect to the chassis between:
• a standby position in which the moveable waveguide is configured to obstruct the at least one opening and, together with the fixed waveguide, form a forward-facing surface of the waveguide assembly;
• an operational position in which the moveable waveguide is configured to allow sound to exit the cavity through the at least one opening;
• wherein the moveable waveguide is configured to be moved from the standby position to the operational position by retracting at least a part of the moveable waveguide in a rearwards direction along the primary axis of the waveguide assembly, wherein the rearwards direction is opposite to the forwards direction;
• wherein the moveable waveguide includes a flexible waveguide element which is configured to flex so as to be movable with respect to the chassis between a standby position and an operational position.

A loudspeaker assembly including:

• a loudspeaker;
• and
• a waveguide assembly for guiding sound;
• wherein the waveguide assembly includes:
• a chassis that provides a cavity configured to receive sound propagating in a forwards direction along a primary axis of the waveguide assembly;
• a fixed waveguide that is fixed with respect to the chassis and positioned on the primary axis of the waveguide assembly, wherein the fixed waveguide is spaced apart from the chassis and is configured to guide sound received by the cavity through at least one opening formed between the fixed waveguide element and the chassis;
• a moveable waveguide that is moveable with respect to the chassis between:
• a standby position in which the moveable waveguide is configured to obstruct the at least one opening and, together with the fixed waveguide, form a forward-facing surface of the waveguide assembly;
• an operational position in which the moveable waveguide is configured to allow sound to exit the cavity through the at least one opening;
• wherein the moveable waveguide is configured to be moved from the standby position to the operational position by retracting at least a part of the moveable waveguide in a rearwards direction along the primary axis of the waveguide assembly, wherein the rearwards direction is opposite to the forwards direction;
• wherein the moveable waveguide includes a plurality of moveable waveguide elements, each of which is movable with respect to the chassis between a respective standby position and a respective operational position;
• wherein the loudspeaker is configured to produce sound that is received by the cavity of the waveguide assembly with the sound received by the cavity of the waveguide assembly propagating in the forwards direction along the primary axis of the waveguide assembly.
