The volume adjusting module 128 is used for turning down the volume on the earplug 124 to a first predetermined level in response to the second driving signal, and further used for turning down the volume on the earplug 124 to a second predetermined level in response to the adjusting signal. The second predetermined level is lower than the first predetermined level.
In addition, the first driver 150 is further used for restoring the earpiece 120 to return to the first receiving space 108 in response to the completion signal. The second driver 160 is further used for restoring the mouthpiece 130 to return to the second receiving space 109 in response to the completion signal. The third driver 126 is used for restoring the earplug 124 to return to the enclosure 122 in response to the completion signal.
Referring to FIG. 5, a communication method of a mobile communication device is provided. The mobile communication device includes a main body, a communication unit, an earpiece, and a mouthpiece. The earpiece and the mouthpiece are capable of rotating with respect to the main body. The communication unit is used for establishing a connection between the mobile communication device and another communication device, and generating a starting signal when the connection between the mobile communication device and another communication device is established. The earpiece includes an enclosure and an earplug received in the enclosure, and the earplug is capable of partially protruding out of the enclosure. The earplug is used for receiving audio signals from another communication device through the communication unit, and outputting the audio signals so that a user of the communication device can hear audio corresponding to the audio signals. The method includes the following steps.
In step S801, determining whether the starting signal is generated. If it is determined that the starting signal is generated, step S803 is implemented. If it is determined that the starting signal is not generated, step S801 is repeated.
In step S803, collecting ambient sound of the mobile communication device, and determining an ambient noise level according to the collected ambient sound. In the embodiment, the step S803 is implemented by the mouthpiece.
In step S805, determining whether the ambient noise level is equal to a predetermined value. If it is determined that the ambient noise level is not equal to the predetermined value, step S807 is implemented. If it is determined that the ambient noise level is equal to the predetermined value, the procedure is ended.
In step S807, rotating the earpiece towards an ear of the user.
In step S809, rotating the mouthpiece towards the mouth of the user.
In step S811, determining whether the ambient noise level is higher or lower than the predetermined value. If it is determined that the ambient noise level is higher than the predetermined value, step S813 is implemented. If it is determined that the ambient noise level is lower than the predetermined value, step S817 is implemented.
In step S813, driving the earplug to partially protrude out of the enclosure and insert into the ear of the user.
In step S815, turning down the volume on the earplug to a first predetermined level.
In step S817, turning down the volume on the earplug to a second predetermined level. The second predetermined level is lower than the first predetermined level.
In use, when the user of the mobile communication device 99 is located in noisy environment, such as a public house or a railway station, thus the ambient volume is high, the earpiece 120 and the mouthpiece 130 are respectively driven by the first driver 150 and the second driver 160 to rotate towards the ear and mouth of the user, and the earplug 124 is driven by the third driver 126 to protrude out of the enclosure 124 and insert into the ear of the user. Therefore, the ambient sound affects is minimized and the communication quality is improved. Furthermore, when the earplug 124 is being inserted into the ear of the user, the volume of the audio coming from the earplug 124 may be too loud resulting in harm to the inner ear, thus the volume adjust module 128 turns down the volume on the earplug 124 to the first predetermined level.
In addition, when the user of the mobile communication device 99 is located in quiet environment, such as a library, thus the ambient volume is low, the earpiece 120 and the mouthpiece 130 are respectively driven by the first driver 150 and the second driver 160 to rotate towards the ear and mouth of the user. Therefore, the user of the mobile communication device 99 can speak softly with a user of another communication device. Meanwhile, the volume adjust module 128 turns down the volume on the earplug 124 at the second predetermined level, thus other persons are not affected.
It is to be understood, even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only; and that changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
