## Claims

### Claim 1

A recorder with a mute (6) comprising a removable connector (7), and a rim (8) that supports the removable connector, said removable connector and rim provided for preventing dislodging of the mute from its soundproofing position,
said rim is formed by two circumferential arcs (9) that respectively emerge from each side of a window (4) of the recorder, and said arcs are arranged symmetrically along at least one part of the contour of the head (1) of the recorder in a section located in a transverse plane that contains an edge (3.1) of a bevel of the mute (3);

### Claim 2 (depends on 1)

The recorder with a mute of claim 1, wherein each of the two circumferential arcs of the rim has a length of less than half the circumferential arcs of the section, said circumferential arcs of the rim each run from one side of the window (4) along a circumferential arc of the rim to the opposite side of the window.

### Claim 3 (depends on 1)

The recorder with a mute of claim 1, wherein the two circumferential arcs of the rim are joined such that the rim (8) covers the entire contour of the section from one side of the window (4) to the opposite side of the window.
