    • A toy phonograph comprises means for pressing a pickup arm into engagement with a phonograph record for reproducing recorded sound from the phonograph record playing surface during rotation thereof. The sound is picked up from a sound reproducing groove in the playing surface by direct resilient contact of a speaker cone assembly with the pickup arm. The speaker cone assembly includes a lift bar containing an aperture adjacent the end of the recording with a protrusion on the pickup arm being received in the aperture as the pickup arm reaches the end of the recording. The drive means for the turntable has an associated electrical contact located between the phonograph record playing surface and the lift bar. When the protrusion is received in the lift bar aperture, the lift bar drops a sufficient amount to engage a leaf spring contact which is normally biased to a closed circuit condition to open the circuit and thus shut off the drive means. Two records may be provided on opposite sides of a common turntable with two separate identical means connected in parallel so that the common turntable may be driven if either of the respective pickup arm protrusions is not received in its respective lift bar aperture. The device may function as a talking toy bank responsive to insertion of a coin.
    • 玩具留声机包括用于按压拾音臂与留声机记录接合的装置,用于在旋转期间再现来自留声机记录播放表面的记录声音。 通过扬声器锥形组件与拾取臂的直接弹性接触,声音通过播放表面中的声音再现槽拾取。 扬声器锥形组件包括提升杆,该提升杆包含邻近记录端部的孔口,当拾取臂到达记录结束时,拾取臂上的突起被容纳在孔中。 用于转台的驱动装置具有位于留声机记录播放表面和提升杆之间的相关联的电触点。 当突起被接收在提升杆孔中时,提升杆下降足够的量以接合通常被偏置到闭路状态的板簧接触件,以打开电路并因此切断驱动装置。 两个记录可以在公共转盘的相对侧上设置,其中两个单独的相同装置并联连接,使得如果相应的拾取臂突起中的任一个没有被接收在其相应的提升杆孔中,则公共转盘可以被驱动。 该装置可以响应于插入硬币而用作说话的玩具库。
