| description | An aspect of the present invention provides a speaker for a vehicle using a strontium magnet and the vehicle including the same. The speaker for a vehicle according to an embodiment includes a magnet which generates a magnetic field. The magnet may include 7.32 to 8.09wt% strontium with regard to the total weight of the magnet; 0.46 to 0.51 wt% lanthanum oxide; 1.14 to 1.26 wt% cobalt oxide; 0.56 to 0.61 wt% chrome oxide; 0.24 to 0.27 wt% calcium oxide; and 85.26 to 94.24 wt% iron oxide. So, the weight of the speaker can be reduced without the loss of sound quality.
일 측면은 스트론튬계 마그넷이 적용된 차량용 스피커 및 이를 포함하는 차량을 제공하고자 한다. 일 실시 예에 따른 차량용 스피커는 자속을 발생시키는 마그넷을 포함하고, 마그넷은, 전체 마그넷 중량 대비 스트론튬 7.32 내지 8.09 중량 %; 산화 란타넘 0.46 내지 0.51 중량 %; 산화 코발트 1.14 내지 1.26 중량 %; 산화 크롬 0.56 내지 0.61 중량 %; 산화 칼슘 0.24 내지 0.27 중량 %; 및 산화 철 85.26 내지 94.24 중량 %;를 포함할 수 있다. |
