Abstract
Official abstract text for this publication.
A sound output device for a vehicle includes an external member body, a vibrator arranged at an inner side of the vehicle with respect to an exterior member body, and coupling portions coupling the exterior member body and the vibrator. The coupling portions are arranged on a circumference of an imaginary circle located on the inner surface of the exterior member body. The diameter of the imaginary circle and the frequency of vibration of the vibrator are set so that vibrations propagated through the coupling portions overlap each other in the center of the imaginary circle of the exterior member body.
First claim
Opening claim text (preview).
What is claimed is: 1 . A sound output device for a vehicle, the sound output device, comprising: an exterior member body including a portion of an outer shell of the vehicle; a vibrator arranged at an inner side of the vehicle with respect to the exterior member body and configured to vibrate when energized; and coupling portions projecting from an inner surface of the exterior member body and connecting the exterior member body to the vibrator, wherein the sound output device is configured to vibrate the exterior member body using vibration of the vibrator propagated through the coupling portions and output a sound wave generated in accordance with the vibration of the exterior member body to an outside of the vehicle, the coupling portions are arranged on a circumference of an imaginary circle located on the inner surface of the exterior member body, and a diameter of the imaginary circle and a frequency of the vibration of the vibrator are set so that vibrations propagated through the coupling portions overlap each other and are intensified in a center of the imaginary circle of the exterior member body. 2 . The sound output device according to claim 1 , wherein the frequency is greater than or equal to 100 Hz and less than or equal to 2000 Hz, and the diameter of the imaginary circle is greater than or equal to 50 mm and less than or equal to 250 mm.
