Detailed Description

Unless defined otherwise, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art.

In the embodiments of the present application, reference to "front" and "rear" is made to front and rear as shown in the drawings. "first end" and "second end" are opposite ends.

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

As shown schematically in fig. 1, the present embodiment provides a headset 10. The headphone 10 includes a left speaker group 11, a right speaker group 12, and a control device 13.

Illustratively, the left speaker group 11 includes at least two bone conduction speakers at different wearing positions, and the left speaker group 11 is electrically connected to the control device 13; the right speaker group 12 includes at least two bone conduction speakers at different wearing positions, and the right speaker group 12 is electrically connected to the control device 13.

The bone conduction speaker is a speaker which converts sound into mechanical vibration with different frequencies based on a bone conduction principle.

The principle of bone conduction refers to the transmission of sound waves through the skull, the bony labyrinth, the lymph of the inner ear, the spiral organ and the auditory center of a human being. For example, when a person chews a cookie, the sound of cracking of the cookie can be heard, namely because the cracked vibrations of the cookie are transmitted to the inner ear of the person through the teeth and skull. Compared with the mode that the propagation medium is air, the sound propagated by bone conduction directly reaches the inner ear through the skull, so that the attenuation and the change of the energy and the tone color of the sound are relatively small.

Illustratively, a coil vibrator is provided in the bone conduction speaker, and an audio signal is transmitted to the wearing position through the coil vibrator. Specifically, the bone conduction speaker is used to transmit vibration signals converted from electric signals to the auditory nervous system of a human through bones, so as to realize sound transmission. The coil vibrator converts the audio signal into mechanical vibration for simulating a mode of skull propagation sound, and reduces propagation loss, so that the obtained sound is played differently.

Illustratively, the control means 13 for sending a left-side audio signal to the left-side speaker group 11 and sending a right-side audio signal to the right-side speaker group 12; specifically, the left speaker group 11 transmits the left audio signal to a position corresponding to the left skull of the person; the right speaker group 12 transmits the right audio signal to a position corresponding to the right skull of the person.

The left audio signal and the right audio signal may include a plurality of signal types, for example, the left audio signal includes a first ear audio signal and a second ear audio signal. The first-ear audio signal is transmitted to the left speaker group 11 through the control device 13, and one bone conduction speaker in the left speaker group 11 transmits the first-ear audio signal to the inside of the left ear of the person; the second-ear audio signal is transmitted to the right-side speaker group 12 through the control device 13, and one bone conduction speaker in the right-side speaker group 12 transmits the second-ear audio signal to the inside of the right ear of the person. First ear audio signal and second ear audio signal can be the same, also can be different, and the same audio signal makes people's left and right ears acquire the same broadcast sound, and different audio signal makes people's left and right ears acquire different broadcast sounds, brings the error phenomenon of sense of hearing for people's auditory system to form specific broadcast effect.

Illustratively, at least two bone conduction speakers included in the left speaker group 11 and the right speaker group 12 for delivering the same audio signal to different wearing positions; or for delivering different audio signals to different wearing locations.

For example, the left speaker group 11 includes three bone conduction speakers, and transmits the same audio signal to three different wearing positions around the left ear of the human. Based on three different wearing positions, the left speaker group 11 can form a wraparound sound propagation in the left skull of the person, thereby forming a stereo sound. As another example, the right speaker group 12 includes four bone conduction speakers that deliver four different audio signals to the right forehead, inside the right ear, above the right ear, and the right hindbrain of the person, respectively. Based on four different wearing positions and four different audio signals, the right speaker group 12 can form a wraparound sound propagation at the right skull of the person, thereby forming a stereo sound.

To sum up, in the earphone 10 that this application embodiment provided, through the cooperation of at least two bone conduction speaker that are located different wearing positions and use, to the wearing position transmission audio signal that corresponds, especially transmit different audio signal for received audio signal is different on the wearing position of difference, thereby has improved earphone 10 and has formed three-dimensional sound propagation.
