    • PURPOSE: To provide such an oscillator for a vibration generator of a compact wireless walkie-talkie that can combine it to a motor revolution axis with a strong drawing power even with a small caulking force, whereby promoting additional compactness of the entire device. CONSTITUTION: The oscillator 10 is made up of a super heavy alloy molded with powdered materials, mainly composed to tungsten, which is integrally combined to the motor revolution axis 12 of the vibration generator for a compact wireless walkie-talkie by the caulking power, and in the periphery of a deflected load part 11, a groove part 13 is formed, and the groove part 13 is formed of an axis inserting part 13a which lets it indwell in the range of more than 180 degrees of center angle of the revolution axis and a standing wall part 13b which is formed between the axis inserting part 13a and an opening 15 of the groove part and opposites to the standing wall part 13b through a narrower space than the outside dimension D of the revolution axis.
    • 目的:为紧凑型无线对讲机的振动发生器提供这样的振荡器,即使在小的挤压力下也能将其与电动机转轴相结合,具有强的拉力,从而提高了整个装置的附加紧凑性。 构成:振荡器10由主要由钨组成的粉末材料成型的超重合金构成,其通过铆接力与紧凑型无线对讲机的振动发生器的电动机转轴12整体组合,以及 在偏转负载部11的周围,形成有槽部13,槽部13由轴插入部13a形成,该轴插入部13a使其停留在旋转轴的中心角度的180度以上的范围内, 形成在轴插入部13a和槽部的开口部15之间的立壁部13b,并且通过比旋转轴的外侧尺寸D更窄的空间与立壁部13b相对。
