Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth speakers lack flexibility in placement options, as they can only be placed on a horizontal surface or a low slope, limiting their usability in various scenarios.
Innovation Solution
A magnetically attractable Bluetooth speaker design that includes a magnetically secured speaker housing, allowing attachment to metal surfaces, mobile phones, and other flexible positioning options through the use of a ring-shaped N52 neodymium iron boron magnet and a horn-shaped speaker body with a silicone pad for enhanced stability and friction prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a magnet is added to the speaker housing to enable magnetic attachment, then the placement flexibility and versatility are improved, but the device complexity increases
Solution Approach 1:
The magnet is integrated into the speaker housing structure, merging the magnetic attachment function with the existing speaker body. This combining approach enables versatile placement options (on metal surfaces, refrigerators, walls, or magnetic stands) without requiring a separate attachment device, thus improving adaptability while minimizing the increase in device complexity.
2Device complexity
If the magnet is placed inside the magnetic circuit range, then the structural integration is improved, but the speaker performance deteriorates due to magnetic interference
Solution Approach 1:
The magnet is extracted from the magnetic circuit range and positioned in a location that does not interfere with the speaker's magnetic field. Specifically, the magnet is placed on the housing structure away from the loudspeaker assembly, ensuring that the magnetic circuit components (magnetic pole, magnetic circuit plate, diaphragm) operate without interference, thus maintaining speaker performance while achieving structural integration.
Solution Approach 2:
The housing structure is designed with differentiated functional zones: one area accommodates the magnet for attachment purposes, while another area maintains the magnetic circuit components for audio output. This local differentiation ensures that the magnetic attachment function and the audio playback function operate independently without mutual interference, preserving both structural integration and speaker reliability.

AI summary
A magnetically attractable Bluetooth speaker is disclosed, including a speaker housing, a loudspeaker, a control circuit board, and a magnet. The loudspeaker is electrically connected to the control circuit board. The speaker housing includes a limiting part for securing the magnet. The magnet is fixedly arranged in the limiting part, and the magnet is arranged outside the magnetic circuit range of the loudspeaker. With such a structure, by arranging the magnet in the speaker housing, the user experience of the speaker can be greatly improved, so that the user can place it in different manners depending on their different needs. Compared with the traditional ordinary speakers that can only be placed on a horizontal plane or a surface with a small slope, the speaker provided by the present disclosure has better flexibility in use.
