## Abstract

A receiver assembly including a first receiver having a distinct longitudinal direction and a first longitudinal centre line, and a second receiver having a distinct longitudinal direction and a second longitudinal centre line. The distinct longitudinal directions of the first and second receivers are arranged essentially along a distinct longitudinal direction of the receiver assembly. The receiver assembly further includes one or more microphone units.

## Claims

### Claim 1

An acoustical assembly comprising
an assembly housing,
a receiver module,
one or more spacers positioned between an inner wall of the assembly housing and the receiver module for positioning the receiver module within the assembly housing, the one or more spacers forming a free-space region between the assembly housing and the receiver module, and
one or more microphone units for receiving incoming sound and being least partly positioned in the free-space region between the inner wall of the assembly housing and the receiver module, wherein the one or more microphone units is/are secured to the inner wall or integrated with the assembly housing along the inner wall, and wherein the one or more spacers include one or more vibration isolating elements to vibration isolate the inner wall of the assembly housing from receiver-generated vibrations originating from the receiver module while the one or more microphone units is/are positioned at least partly in the free-space region.

### Claim 2 (depends on 1)

An acoustical assembly according to claim 1, wherein the one or more microphone units comprise MEMS microphones.

### Claim 3 (depends on 1)

An acoustical assembly according to claim 1, wherein the one or more microphone units comprise electret microphones.

### Claim 4 (depends on 1)

An acoustical assembly according to claim 1, wherein the one or more microphone units comprise a MEMS microphone unit comprising a MEMS microphone having a sound inlet and a signal processing circuit.

### Claim 5 (depends on 4)

An acoustical assembly according to claim 4, wherein the MEMS microphone unit further comprises a closed rear volume defined by a separation wall.

### Claim 6 (depends on 1)

An acoustical assembly according to claim 1, wherein the receiver module comprises a single receiver.

### Claim 7 (depends on 6)

An acoustical assembly according to claim 6, wherein the single receiver comprises one or more moving armature receivers.

### Claim 8 (depends on 7)

An acoustical assembly according to claim 7, wherein the one or more moving armature receivers comprise one or more balanced armature receivers.

### Claim 9 (depends on 1)

A hearing device comprising an acoustical assembly according to claim 1, said hearing device comprising a hearing aid being selected from the group consisting of: behind-the-ear, in-the-ear, in-the-canal and completely-in-the-canal.
