Embodiment Construction

[0032] With the increasingly fierce competition in the mobile phone industry, manufacturers in order to enable mobile phone users to get a better experience, by canceling the 3.5mm headphone jack to obtain the improvement of other mobile phone parameters, for example, iPhone 7 uses the Lightning interface for charging, data transmission and audio output. By canceling the dedicated 3.5mm audio interface, the mobile phone becomes thinner. More importantly, the screen of the same size can be placed in a smaller mobile phone to obtain a larger screen-to-body ratio, and the Lightning interface Headphones can output higher-resolution sound effects. However, this design also caused problems for users. Both the charging data cable and the amp use the Lightning interface. When charging, the user cannot use the amp with the Lightning interface to connect to listen to music, and cannot use the same when listening to music. The charging data cable of the interface performs charging and dat...

Abstract

The invention discloses a mobile audio power supply system and an audio output and charging method. The system includes a mobile terminal, a headphone and a mobile audio power supply, wherein the mobile audio power supply includes a connection circuit, a data transmission circuit, a power supply circuit, a control circuit, an audio decoding circuit and a headphone amplifier. The method includes the following steps: the mobile terminal is connected through a data line of the mobile audio power supply; the mobile audio power supply sends a control instruction to the mobile terminal to ensure that the mobile terminal enables a working mode of simultaneously charging and outputting an audio; the power supply circuit stores electric energy and charges the mobile terminal; and the headphone is connected to the mobile audio power supply through high and low resistance audio interfaces to obtain audio output. According to the scheme of the invention, the defects that some mobile terminal interfaces cannot simultaneously perform charging and audio output acquisition can be overcome, especially when a user needs to use the mobile audio power supply disclosed by the invention to charge the mobile terminal and acquire the audio output at the time of going out, the user experience can be greatly improved.

Description

Technical field [0001] The present invention relates to the technical field of mobile terminal charging and audio output, and more specifically, to a mobile audio power supply and an audio output and charging method for simultaneously realizing charging and audio output. Background technique [0002] Existing general mobile terminals such as iPhone series mobile phones, Android series mobile phones and tablet computers have a dedicated 3.5mm headphone jack for users to connect to the amp; however, due to the design of the 3.5mm headphone jack, the internal space of the iPhone has been compressed. Take the iPhone 6s as an example, the length of the headphone jack position almost occupies the position outside the display area at the bottom of the screen. With the increasingly fierce competition in the mobile phone industry, manufacturers in order to enable mobile phone users to get a better experience by canceling the 3.5mm headphone jack. Improvement of other parameters of the mob...
