Jack Size? I bought an MP3 player on Ebay a while ago and it works good, but it doesn't have any brand name on it so I can't say who makes it, all I know is that it's from China. My dilema is that I want to buy some speakers for it and the jack is smaller than a normal 3.5mm jack, so I don't know where to look for speakers.
Specific models are termed stereo plug, mini-stereo, mini jack, headphone jack and microphone jack, or are referred to by size, i.e. 3.5mm or 6.35mm. In the UK, the terms jack plug and jack socket are commonly used for the respective male and female phone connectors. In the US, a stationary (more fixed) electrical connector is called a jack.
