Loud Speaker

Exact specifications are not readily available from Oppo, but based on user reports and replacement parts listings, it's likely a bottom-firing speaker with a typical smartphone power output, suitable for moderate volume levels in most environments. Plays audio for ringtones, notifications, music, and video playback. Generates buzzing sounds for alarms and vibrations. The sound quality is described as clear and balanced, though not particularly bass-heavy or loud compared to some flagship phones. The buzzer is considered audible enough for most situations, although some users report it being slightly faint in noisy environments. The loudspeaker buzzer module is located on the bottom rear of the phone, near the charging port. If you experience any issues with the loudspeaker or buzzer, such as distorted sound, low volume, or complete failure, it may be necessary to have the module replaced.
