Abstract

The invention provides a multipurpose radio communication device, comprising an audio signal receiving unit, an audio regulation unit and an audio signal outputting unit which are electrically connected in sequence; the audio signal receiving unit is used for receiving an audio signal which is processed and transmitted to the audio regulation unit; the regulated audio signal is output by the audiosignal outputting unit; and the audio regulation unit can amplify specific band of the audio signal. The invention also provides an audio regulation method used by the multipurpose radio communication device.

Description

technical field [0001] The present invention relates to a multifunctional wireless communication device, in particular to a multifunctional wireless communication device with audio adjustment function and an audio adjustment method used therein. Background technique [0002] The International Electrotechnical Association IEC581 standard and my country's GB / T14277-93 national standard divide audio frequency bands into: 30-150Hz is the low frequency band, 150Hz-500Hz is the middle and low frequency band, 500KHz-5KHz is the middle and high frequency band, and 5KHz-16KHz is the high frequency band . The frequency range that the human ear can hear is generally 20Hz-20KHz. As people age, generally, mild hearing impairment will first appear in high-frequency audio. Therefore, when the middle-aged and elderly users use the wireless communication device, they need to amplify the high-frequency audio specially to obtain better voice listening quality. [0003] The existing wireless c...
