Ear probe for hearing testing

Ear probe assembly comprising:

• a housing structure having a proximal side and a distal side;
• and
• at least three transducers arranged in said housing structure, said at least three transducers including a first transducer comprising a first sound port, a second transducer comprising a second sound port, and a third transducer comprising a third sound port,
• wherein respective longitudinal axes of said first, second, and third sound ports are parallel to one another;
• wherein a channel structure comprises at least a first transducer entrance configured to receive said first sound port, a second transducer entrance configured to receive said second sound port, and a third transducer entrance configured to received said third sound port, wherein said channel structure protrudes from said proximal side of said housing structure, and
• wherein said channel structure forms respective acoustic paths between said first, second, and third transducers and a tip portion of said ear probe, said tip portion being configured to connect with said channel structure,
• wherein said tip portion further comprises a set of integrated acoustic channels, wherein the set of integrated acoustic channels are configured to connect with said channel structure in a detachable manner,
• wherein the first transducer comprises a first membrane and the second transducer comprises a second membrane, wherein the first and second transducers are arranged in the housing structure, such that the first membrane lies substantially perpendicular to the second membrane, the first membrane substantially following the longitudinal axis of the first sound port, the second membrane following a direction perpendicular to the longitudinal axis of the second sound port,
• wherein the first and second transducers are arranged such that a bottom surface of the first transducer faces a top surface of the second transducer,
• wherein the channel structure comprises three parallel channels corresponding to said first, second, and third transducers, respectively,
• wherein each of the three parallel channels
• shares a same longitudinal axis as the sound port of the corresponding transducer;
• comprises the transducer entrance of the corresponding transducer;
• and
• connects with a corresponding acoustic channel of said tip portion in a proximal end thereof,
• wherein a distal end of said channel structure is configured to receive said first and second sound ports of said first and second transducers.
