Loudspeaker is the small component through which we hear ringtone, alarm and voice of people when we take calls on speakers. The function of speaker is to receive signals in form of electromagnetic waves and convert them into the sound that is hearable and understandable to us. The process of conversion of electromagnetic waves is done inside the internal circuitry of phones. The iPhone 6s has loudspeaker placed near the charging port where there are few holes from where we hear the sound. The loudspeakers are widely used for entertainment stuff and video calls. The loudspeaker is assembled in single flex assembly and often requires replacement in case of non functionality. There are several reasons behind a problematic loudspeaker in iPhone 6s and MyCelCare knows the solution to all.
