Audio device with charging contacts on printed circuit board

An audio device comprising:

• a housing;
• one or more loudspeakers within the housing;
• one or more batteries within the housing and electrically coupled to the one or more loudspeakers;
• battery charging circuitry within the housing and electrically coupled to the one or more batteries;
• and
• a printed circuit board (PCB) at least partially within the housing, the PCB including charging contacts on a surface of the PCB, the charging contacts electrically coupled to the battery charging circuitry,
• wherein at least a portion of the surface of the PCB in combination with the charging contacts form a bottom-facing, outer surface of the audio device, and
• wherein at least one of the charging contacts is elliptical.

A system comprising:

• an audio device including
• a housing,
• one or more loudspeakers within the housing,
• one or more batteries within the housing,
• battery charging circuitry within the housing and electrically coupled to the one or more batteries, and
• a printed circuit board (PCB) at least partially within the housing, the PCB including charging contacts on a surface of the PCB, the charging contacts electrically coupled to the battery charging circuitry;
• and
• a charging dock including electrical connectors configured to make physical contact with the charging contacts of the audio device in any relative radial orientation about an axis when the audio device is engaged with the charging dock.
