Abstract
An audio system for a vehicle is provided with a woofer speaker having a front side for producing a required bass-range acoustic output in a passenger compartment of the vehicle and a back side having an infinite baffle. The audio system includes a bass-compatible speaker disposed in the passenger compartment of the vehicle. A controller is in communication with the woofer and the bass-compatible speaker and is programmed to distribute the required bass-range sound output to the woofer and the bass-compatible speaker based on at least one of a vehicle speed and a sound output level of the audio system.
Claims21
An audio system for a vehicle comprising:
- a woofer speaker having a front side for producing a required bass-range acoustic output in a passenger compartment of the vehicle and a back side having an infinite baffle;
- a bass-compatible speaker disposed in the passenger compartment of the vehicle;
- and
- a controller in communication with the woofer and the bass-compatible speaker and programmed to:
- distribute the required bass-range sound output to the woofer and the bass-compatible speaker based on at least one of a vehicle speed and a sound output level of the audio system.
A method of controlling an audio system in a vehicle, the method comprising:
- operating a woofer speaker to provide a required bass-range acoustic output;
- receiving vehicle data indicative of a vehicle speed;
- determining a current sound pressure level in a passenger compartment of the vehicle;
- and
- operating a bass-compatible speaker to provide at least a portion of the required bass-range sound output if at least one of the vehicle speed is less than a threshold speed and the current sound level is greater than a threshold volume.
A speaker arrangement for producing bass-range sound in a vehicle, the speaker arrangement comprising:
- at least one woofer mounted to a vehicle body structure, the woofer comprising:
- a front side in fluid communication with a passenger compartment to emit sound into the passenger compartment;
- and
- a back side of the woofer in fluid communication with an environment outside the passenger compartment, wherein the back side of the woofer is not contained in a speaker enclosure, thereby improving bass-range sound in the vehicle and reducing vibrations.
