摘要： An engine-sound accessory for an electric toy vehicle produces a sound output which varies its characteristics in proportion to an electric input to the toy vehicle. The apparatus measures the total electric current fed to the toy vehicle to produce a sound control signal proportional thereto. When two or more vehicles are fed from a common power source, the apparatus is responsive to the sum of the electric current fed to the two or more vehicles whereby variation in the electric current fed to one or both of the vehicles produces a corresponding variation in the sound characteristic.
摘要翻译：用于电动玩具车辆的发动机声音附件产生声音输出，其与玩具车辆的电力输入成比例地改变其特性。该装置测量馈送到玩具车辆的总电流以产生与其成比例的声音控制信号。当两个或多个车辆从公共电源馈送时，该装置响应于馈送到两个或更多个车辆的电流的总和，由此馈送给一个或两个车辆的电流的变化产生相应的变化声音特点。

摘要： A toy vehicle and toy vehicle game are disclosed in which a plurality of controllable toy vehicles collect current from conductor strips in a slotless track and switch lanes when current polarity is reversed. A toy drone car is used in the game which collects current from the strips associated with the other cars and it includes an electrical circuit which insures that current of only a predetermined desired polarity is supplied to the motor in the vehicle to propel the vehicle in a forward direction around the track. As a result, the vehicle is driven about the track in a forward direction regardless of the polarity of current applied to the collector strips. In addition, the drone car includes an automatic steering system which causes the drone car to continuously switch lanes in an apparently random alternating manner as it moves along the track.
摘要翻译：公开了一种玩具车和玩具车游戏，其中多个可控制的玩具车辆在电流极性相反时从无槽轨道中的导体条和开关通道收集电流。在游戏中使用玩具无人驾驶车，其从与其他轿厢相关联的条收集电流，并且其包括电路，其确保只有预定期望极性的电流被提供给车辆中的电动机以将车辆推进在前进方向绕轨道。结果，无论施加到收集器条的电流的极性如何，车辆都沿着前进方向围绕轨道被驱动。此外，无人驾驶汽车包括自动转向系统，其使得无人驾驶车辆沿着轨道移动时以显然随机的交替方式连续地切换车道。

摘要： The toy doll includes a flexible body and a head portion which are shaped to respectively include the upper and lower portions of the doll's mouth. Means are provided in the head for pivoting the head portion with respect to the body when the body is squeezed, thereby to open and close the doll's mouth. A reed sound mechanism is provided in the body for making a child-like sound when the body is squeezed.
摘要翻译：玩具娃娃包括柔性体和头部，其形状分别包括娃娃嘴的上部和下部。在头部设置有用于当身体被挤压时使头部相对于身体枢转的装置，从而打开和关闭娃娃的嘴。身体中提供芦苇声音机构，用于在身体被挤压时产生儿童般的声音。
