스피커용 자기회로Magnetic circuit for speaker

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 스피커용 자기회로의 일실시예를 도시한 단면도1 is a cross-sectional view showing an embodiment of a magnetic circuit for a speaker of the present invention.

제8도는 본 발명의 제2실시예의 스피이커용 자기회로의 단면도8 is a cross-sectional view of the magnetic circuit for the speaker of the second embodiment of the present invention.

제13도는 제1도의 자기회로의 포울부의 단면형상을 바꾼경우의 다른 실시예를 도시한 단면도13 is a cross-sectional view showing another embodiment in the case where the cross-sectional shape of the fouling portion of the magnetic circuit of FIG. 1 is changed.

Claims (5)

플레이트 및 요우크베이스의 사이에 외주 상하각부를 C면 또는 R면의 단면형상으로하는 마그넷을 끼워둔것을 특징으로하는 스피이커용 자기회로.A magnetic circuit for a speaker, wherein a magnet having an outer circumferential upper and lower portion in the cross-sectional shape of the C surface or the R surface is sandwiched between the plate and the yoke base. 플레이트 및 요우크베이스의 사이의 마그넷으니 외주측단면을 상하각부에서 중앙부로 향하여 경사한 경사면의 단면형상으로 구성한것을 특징으로 하는 스피이커용 자기회로.A magnetic circuit for a speaker, characterized in that the magnet is formed between the plate and the yoke base so that the outer circumferential side surface is formed in the cross-sectional shape of the inclined surface inclined from the upper and lower angle portions to the center portion. 플레이트 및 요우크베이스의 사이의 마그넷의 외주측단면을 중앙부가 대직경으로 된 곡면상으로 만곡된 단면형상으로 한것을 특징으로 하는 스피이커용 자기회로.A magnetic circuit for a speaker, characterized in that the outer circumferential side surface of the magnet between the plate and the yoke base has a cross-sectional shape curved in a curved shape with a large diameter at the center portion. 제1항, 2항, 3항중 어느 한 항에 있어서, 플레이트 및 요우크베이스의 외주면이 곡면상으로 형성되어 있는것을 특징으로하는 스피이커용 자기회로.The magnetic circuit for a speaker according to any one of claims 1, 2 and 3, wherein the outer peripheral surfaces of the plate and the yoke base are formed in a curved shape. 요우크베이스와 플레이트와의 사이에 마그넷이 끼워져서 이루어지는 스피이커용 자기회로에 있어서, 적어도 상기 요우크베이스에 이 외주연부의 두께가 얇아지도록, 내측으로 만곡한 형상의 테이퍼가 설치되어 있는것을 특징으로 하는 스피이커용 자기회로.A speaker magnetic circuit in which a magnet is sandwiched between a yoke base and a plate, wherein at least the yoke base is provided with an inwardly curved taper so that the thickness of the outer peripheral portion thereof becomes thinner. Speaker magnetic circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
