Amplifier
Amplifier:Electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction.
Built-in
Audio
Sensitivity:Responsiveness to audio slight changes.
75 dB
Impedance:The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.
4 O
RMS rated power:RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplfiers and loudspeakers.
20 W
Design
International Protection (IP) code:The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
IPX7

Bluetooth:Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.
Wi-Fi:Popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.
