Integrated Power Bank Speaker Merging Audio and Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices require multiple batteries for outdoor use and separate power sources for external speakers, leading to inconvenience and inefficiency, as existing power banks occupy a USB port when powering speakers.
Innovation Solution
A power bank apparatus with integrated speaker functionality, including a microcontroller unit, power bank charging and battery units, discharging unit, speaker unit, and audio signal input unit, which allows simultaneous charging and power supply to devices while amplifying audio signals through an amplifier unit, optionally using wireless transmission for audio signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users connect portable electronic apparatus to power bank and external speaker simultaneously, then power supply and audio quality are improved, but device complexity and number of connections increase
Solution Approach 1:
The patent combines the power bank and external speaker into a single integrated device. The power bank includes both power supply functionality and speaker functionality, allowing the portable electronic apparatus to connect to one device instead of two separate devices. This reduces connection complexity while maintaining power supply reliability and audio quality.
Solution Approach 2:
The power bank is designed with multi-functionality, serving both as a power supply device and as an external speaker. The integrated device can charge the portable electronic apparatus while simultaneously playing audio, eliminating the need for separate power bank and speaker connections.
2Ease of operation
If external speaker uses battery power, then portability is improved, but duration of action decreases due to easy power depletion
Solution Approach 1:
The power bank and speaker are merged into one device with a shared battery system. The battery in the integrated power bank speaker can simultaneously power both the charging function and the speaker function, or switch between them, extending the overall duration of action compared to separate devices.
Solution Approach 2:
The integrated device's battery serves multiple functions - it can charge the portable electronic apparatus, power the speaker, or both sequentially. This multi-functional battery usage extends the effective duration of action while maintaining portability.
3Reliability
If power bank outputs power to external speaker, then audio quality is improved, but power bank output ports are occupied
Solution Approach 1:
By merging the speaker function into the power bank itself, the device eliminates the need to occupy power output ports for speaker power supply. The speaker is powered internally through the shared battery system, freeing up all power bank output ports for charging other devices while maintaining audio quality.
Solution Approach 2:
The speaker power supply function is extracted from the power bank's output ports and integrated into the device's internal battery system. This separation allows the power bank to provide power to the speaker through its own internal power management rather than consuming output port capacity.

AI summary
A power bank apparatus with speaker combines the function of power bank and the function of speaker. The power bank apparatus not only charges the portable electronic apparatuses but also supplies power to the internal speaker. The voice or music of the portable electronic apparatus is amplified by the speaker of the power bank apparatus to improve the quality of the voice or music.
