The present invention relates to an eye alignment apparatus for golf practice. The eye alignment apparatus of the present invention comprises at least one eye leading means and a supporting means. The eye leading means allows a user to view a golf ball placed on the floor through each of sighting holes having different shapes or a straight sighting bar. In particular, the eye leading means is formed with a detachable fastening portion at an end thereof. Further, the supporting means is fixed to a support at an end thereof and formed with a fastening portion, which can be detachably mounted to any one of the eye leading means, at the other end thereof. The eye leading means and the supporting means may be detachably mounted to each other through a variety of fastening structures.

The present invention relates to an apparatus for measuring golf club swing speed. The swing speed measuring apparatus automatically indicates golf club swing speed by detecting a state where optical signals, such as infrared rays, output from a transmitting device thereof are blocked by a golf club. To this end, a receiving device of the swing speed measuring apparatus calculates the golf club swing speed by dividing a distance between the optical signals by a time interval taken between when the optical signals are blocked, and outputs the calculated swing speed. In particular, the transmitting and receiving devices are manufactured as separate devices. The present invention is configured such that a meaningless swing motion such as a case where a user slowly swings the golf club around the ball to take a proper stance or posture can be excluded and an actual swing motion can be distinguished accordingly.

A multiple output transformer network for a high-fidelity sound reproducing system which includes a high-frequency speaker and a low-frequency speaker, first and second output transformers, a high-frequency bandpass filter coupling the secondary of the first output transformer to the high-frequency speaker, and a low-frequency bandpass filter coupling the secondary of the second transformer to the second speaker, all mounted in a remote speaker unit. The primary windings of the transformers are connected to the output amplifier of the sound reproducing equipment by first and second extension leads. The output amplifier includes first and second triodes series connected across a source of unidirectional potential, and first and second capacitors coupling the extension leads to the common connection of the triodes.
