However, headphone drivers are usually highly compliant, and headphones don't have a lot of back cavity volume
As a result, the headphones do not produce low-frequency sounds at sufficient volume and are therefore not suitable for use as a loudspeaker listening device

Embodiment Construction

[0022] Convertible headphone systems feature on-ear or circumaural headphones that deliver high-quality sound to the ear. The earphone may be coupled to the external structure in such a way that the rear cavity of the earphone transducer is substantially amplified. This allows the transducer to effectively generate low-frequency sound, so that the headphones can also be used as a loudspeaker listening device.

[0023] Figure 1A and Figure 1B A convertible headset system 300 according to the present disclosure is shown conceptually. An earcup 302 with a sound emitting opening 303 is placed on the head, over or covers the pinna 304 . The transducer 306 provides sound to a volume V fc The front cavity 307 and has a volume V bc in the back or rear cavity 309 of the Ear cup 302 has rear openings or ports 317 and 312 that are selectively decoupled from rear cavity 309 by movable structure 310 . Rear ports 317 and 312 enable tuning of the frequency response of system 300 . T...

Abstract

Provided is a convertible headphone system with headphones having a transducer with a front and a rear, and a back cavity that is fluidly coupled to the rear of the transducer, and an external acoustic structure that defines an acoustic volume. The headphones and the external acoustic structure are configured to be coupled together so as to fluidly couple the back cavity of the headphones to the acoustic volume of the external acoustic structure, to form an expanded back cavity volume.

Description

technical field [0001] The present disclosure relates to a headphone that can also be used as a loudspeaker listening device, where the listening device projects sound into the surrounding environment. Background technique [0002] Headphones are designed to efficiently deliver relatively low volume sounds to the ear. If the headphones can also be used to play music outside, they will do double duty. However, headphone drivers are usually highly compliant, and headphones don't have a lot of back cavity volume. As a result, the headphones do not produce low-frequency sounds at sufficient volume and are therefore not suitable for use as external listening devices. Contents of the invention [0003] All examples and features mentioned below can be combined in any technically feasible way. [0004] In one aspect, a convertible earphone system includes an earphone having a transducer with a front and a rear and a back cavity fluidly coupled to the rear of the transducer. Th...
