## Abstract

An object containing electronic circuits and a rechargeable cell, wherein the cell is arranged close to a surface of the object, a charge coil being shiftable with respect to the cell between an operating position where it is arranged around the cell and a recharge position where it is axially offset with respect to the cell.

## Claims

### Claim 1

An object containing electronic circuits and a rechargeable cell, wherein the cell is arranged close to a surface of the object, a charge coil being shiftable with respect to the cell between an operating position where it is arranged around the cell and a recharge position where it is axially offset with respect to the cell.

### Claim 2 (depends on 1)

The object of claim 1, having a maximum dimension smaller than 20 mm, the cell being cylindrical and having a diameter smaller than 6 mm and a height smaller than 4 mm.

### Claim 3 (depends on 1)

The object of claim 1, forming an in-the-ear hearing aid.

### Claim 4 (depends on 1)

The object of claim 1, wherein the charge coil is fixedly attached to the body of the object and the cell is shiftable away from said surface.

### Claim 5 (depends on 4)

The object of claim 4, wherein a portion of the object located above the cell opposite to said surface is shiftable along with the cell with respect to the body of the object.

### Claim 6 (depends on 5)

The object of claim 5, comprising ratchet means for maintaining the object in operating position.

### Claim 7 (depends on 5)

The object of claim 5, comprising locking means for preventing said portion of the object from sliding beyond the recharge position.

### Claim 8 (depends on 4)

A system for recharging the object of claim 4, comprising a pad supporting, around a ferromagnetic core, a winding having an external diameter corresponding to the internal diameter of the charge coil.

### Claim 9 (depends on 8)

The recharge system of claim 8, wherein the pad comprises means for heating the cell.
