DETAILED DESCRIPTION

[0023] The disclosure is illustrated by way of example and not by way, of limitation in the figures of the accompanying drawings.

[0024] Referring to FIGS. 1-4, the earphone 100 includes a left receiver 10, a right receiver 20, a sound source input end 50, a first frequency divider 71, a second frequency divider 72, a third frequency divider 73 and a fourth frequency divider 74.

[0025] In the embodiment, the earphone 100 is an in-ear earphone. In other embodiments, the earphone 100 may be a headphone.

[0026] The left receiver 10 is configured with a main left loudspeaker 11 and a secondary left loudspeaker 12, and the right receiver 20 is configured with a main right loudspeaker 21 and a secondary right loudspeaker 22.

[0027] The sound source input end 50 includes a left channel audio input end 51 and a right channel audio input end 52. The left channel audio input end 51 electrically connects to the main left loudspeaker 11 via the first frequency divider 71, and the right channel audio input end 52 electrically connects to the main right loudspeaker 21 via the second frequency divider 72. The third frequency divider 73 electrically connects to the secondary right loudspeaker 22, and the third frequency divider 73 is configured for performing a frequency division process toward audio signals inputted from the left channel audio input end 51 and for transmitting the audio signals to the secondary right loudspeaker 22. The fourth frequency divider 74 electrically connects to the secondary left loudspeaker 12, and the fourth frequency divider 74 is configured for performing the frequency division process toward the audio signals inputted from the right channel audio input end 52 and for transmitting the audio signals to the secondary left loudspeaker 12.

[0028] In the embodiment, the earphone 100 further includes a left audio line 30 and a right audit line 40. The first frequency divider 71 and the third frequency divider 73 are configured within the left audio line 30, and the second frequency divider 72 and the fourth frequency divider 74 are configured within the fight audit line 40.

[0029] In other embodiments, the first frequency divider 71 and the third frequency divider 73 may be configured within a chamber of the left receiver 10, and the second frequency divider 72 and the fourth frequency divider 74 may be configured within a chamber of the right receiver 20.

[0030] In view of the above, the secondary left loudspeaker 12 is configured within the left receiver 10, and the secondary right loudspeaker 22 is configured within the right receiver 20. The secondary right loudspeaker 22 and the secondary left loudspeaker 12 are configured to convert the audio signals processed by the third frequency divider 73 and the fourth frequency divider 74. When the user puts on the left receiver 10 and the right receiver 20 to listen to the audio files, except for the sound emitted by the main left loudspeaker 11 and the main right loudspeaker 21, the user can also hear the sound processed by the third frequency divider 73 and the fourth frequency divider 74 configured within the left receiver 10 and the right receiver 20, and wherein the frequency of the sound processed by the third frequency divider 73 and the fourth frequency divider 74 are different from that of the sound emitted by the main left loudspeaker 11 and the main right loudspeaker 21. That is, the audio signals inputted from the right channel audio input end 52 can be heard within the left receiver 10, and the audio signals inputted from the left channel audio input end 51 can be heard within the right receiver 20. As such, the right receiver 20 and the left receiver 10 within the left receiver 10 have been simulated to the hearing characteristics in real scenario, and thus the user may have unprecedented, real and natural environmental listening experience. When the earphone 100 is in its operations, the sound will be in front of the user, instead of on top of the head. Also, the sound in the left and right ranges may be natural within a certain range, instead of being too spacious or exaggerated.

[0031] Further, the earphone 100 also includes a left switch 61, a right switch 62, and a bi-channel switch 60. The left switch 61 electrically connects between the left channel audio input end 51 and the third frequency divider 73 for turning on or off the secondary right loudspeaker 22. The right switch 62 electrically connects between the right channel audio input end 52 and the fourth frequency divider 74 for turning on or off the secondary left loudspeaker 12. The bi-channel switch 60 electrically connects between the left switch 61 and the right switch 62 for turning on or off the left. switch 61 and the right switch 62. In the embodiment, the bi-channel switch 60 is configured on the wirings of the earphone 100 so as to facilitate users' operations.

[0032] The configuration of the left switch 61, the right switch 62, and the bi-channel switch 60 enables the audio switch function of the earphone 100. The user may turn off the bi-channel switch 60, including the secondary right loudspeaker 22 and the secondary left loudspeaker 12 of the earphone 100, to obtain the traditional earphone effect. Thus, the earphone 100 may not only perform traditional operations but also the real and natural listening effect in real scenarios.

[0033] Referring to FIGS. 3 and it, specifically, the left. receiver 10 is configured with a first conduit 13 and a second conduit 14. The first conduit 13 is arranged between the main left loudspeaker 11 and an outer surface 15 of the left receiver 10. The first conduit 13 is configured for transmitting the audio signals from the main left loudspeaker 11 to an outside of the left receiver 10 such that the audio signals may be transmitted to ears of the user. The second conduit 14 is arranged between the secondary left loudspeaker 12 and the outer surface 15 of the left receiver 10. The second conduit 14 is configured for transmitting the audio signals from the secondary left loudspeaker 12 to the outside of the left receiver 10 such that the audio signals may be transmitted to ears of the user. The length L2 of the second conduit 14 is N times of the length L1 of the first conduit 13, and N is an integer greater than or equal to one. In other words, the main left loudspeaker 11 and the secondary left loudspeaker 12 are configured to be interleaved with one other in the chamber of the left receiver 10 so as to obtain the real listening effect.

[0034] Similarly, the right receiver 20 is configured with a third conduit 23 and a fourth conduit 24. The third conduit 23 is arranged between the main right loudspeaker 21 and an outer surface 25 of the right receiver 20. The third conduit 23 is configured for transmitting the audio signals from the main right loudspeaker 21 to an outside of the right receiver 20 such that the audio signals may be transmitted to ears of the user. The fourth conduit 24 is arranged between the secondary right loudspeaker 22 and the outer surface 25 of the right receiver 20. The fourth conduit 24 is configured for transmitting the audio signals from the secondary right loudspeaker 22 to the outside of the right receiver 20 such that the audio signals may be transmitted to ears of the user. The length L4 of the fourth conduit 24 is N times of the length L3 of the third conduit 23, and N is an integer greater than or equal to one. In other words, the main right loudspeaker 21 and the second=right loudspeaker 22 are configured to be interleaved with one other in the chamber of the right receiver 20 so as to obtain the real listening effect.

[0035] Although the features and elements of the present disclosure are described as embodiments in particular combinations, each feature or element can be used alone or in other various combinations within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
