## Abstract

This invention corresponds to a device for binaural capture of sound comprising an upper module, a first external ear and a second external ear incorporated into the upper module in a removable way; two transducers, a transducer is arranged in the first external ear and the other transducer is arranged in the second external ear; and, a clamping-coupling located in the lower part of the upper module.

## Claims

### Claim 1

A device for binaural capture of sound comprising:
an upper module;
a first external ear and a second external ear incorporated into the upper module in a removable way;
two transducers, a transducer is arranged in the first external ear and the other transducer is arranged in the second external ear;
a central axis passing through the upper module;
a clamping-coupling connected to the central axis;
an audio video recording device connected to the clamping-coupling;
wherein the upper module is mounted on the audio video recording device via the clamping-coupling and the central axis; and
wherein the two transducers are connected to the audio video recording device by wiring that passes through the central axis.

### Claim 2 (depends on 1)

The device of claim 1, comprising a lower module coupled to the bottom part of the upper module, configuring an artificial head.

### Claim 3 (depends on 2)

The device of claim 2, characterized in that the artificial head is of a dark color and matte texture.

### Claim 4 (depends on 2)

The device of claim 2, characterized in that the artificial head has a front face with human face morphology.

### Claim 5 (depends on 1)

The device of claim 1, characterized in that the two transducers are omnidirectional microphones.

### Claim 6 (depends on 1)

The device of claim 1, characterized in that the two transducers are selected from the group comprising dynamic microphones, condenser microphones, microphones with frequency response from 20 Hz to 20 kHz, diaphragm microphones between 4 mm and 25.4 mm, sensitivity microphones from 2 to 50 mV @ 1Khz, microphones with maximum sound pressure level between 100 and 160 dB SPL, microphones with distortion levels THD<1% and combinations thereof.

### Claim 7 (depends on 1)

The device of claim 1, characterized in that the first external ear and the second external ear have the morphology of a human ear.
