Soundmax is a speaker brand that has already affirmed its status in the Vietnamese market in the field of research and development and production of speakers. Soundmax frequently provides the market with modern products which are equipped with latest sound technologies to meet the growing needs of entertainment of the customers. Simultaneously, Soundmax also pays great attention to accessories in order to guarantee the efficiency, to increase the life expectancy of the main products and to ensure the users’ safety as well.

  With the production of mobile speakers and built-in battery speakers, the customers now have the means of entertainment whenever and wherever they want. And comes along with these products is Adapter – an accessory that plays a very important role in the guarantee of the battery’s life expectancy, as well as the speakers themselves. And the most important thing is the customers’ safety, when recently some regrettable misfortunes happened due to the fact that customers use Adapter from unclear origins.

  SoundMax Adapter AC/DC is nonlinear Adapter, also known as AC/DC adapter switching that operates based on automatic electronic circuit principle. Starting operation is alternating current from the electric circuit is converted by the rectifier into direct current. The current provided to the transformer is controlled by transistor switching. This transistor switching runs under the control of PWM-Pulse Width Modulation. These potential pulses have high frequency, from 30 to 150 kHz (from 30 000 to 150 000 cycles per second). This frequency is kept stable and the width of the pulse is changed when there is adjustment from the equalizer. The magnetic field therefore inducts on the secondary current to create the alternating current, and will be again adjusted by the secondary equalizer. Afterwards, the direct current that runs through other primary filters, is now ready for the products to use. The advantages of this type of adapter is its neat and light weight, high efficiency, and operating more coolly others. Running voltage has a wide range (auto-volt), fluctuating from 100 VAC to 240 VAC.

  Our ambition is to provide the customers with the best moments of entertainment as well as the safety, thus Soundmax recommends customers to only use the products and accessories that have clear origins. Soundmax Adapter is compatible with all other Soundmax products and other mobile devices that have the same technical parameters.
