AI Technical Summary
Technical Problem
Current speaker modules in portable electronic devices cause strong vibration feelings due to diaphragm vibrations, leading to abnormal noise and affected user experience.
Method used
The speaker module consists of two speaker monomers with diaphragms oriented in opposite vibration directions, sequentially disposed in a vertical direction to offset momentum variations, along with optimized housing structures for improved sound emission and reduced vibration excitation.
Benefits of technology
This configuration significantly reduces vibration excitation and enhances sound quality by minimizing vibration impact on the device, improving user experience and sound loudness.

Abstract
Embodiments of this application provide a speaker module and a portable electronic device. The speaker module includes a first speaker module and a second speaker module. The first speaker module includes a first housing and a first speaker monomer accommodated in the first housing, and the first speaker monomer has a first diaphragm. The second speaker module includes a second housing and a second speaker monomer accommodated in the second housing, and the second speaker monomer has a second diaphragm. The first speaker module and the second speaker module are sequentially disposed in a vertical direction, and a vibration direction of the first diaphragm is opposite to a vibration direction of the second diaphragm, so that momentum variations (mv) Δ of the speaker module are offset against each other, thereby resolving a problem that a vibration feeling is strong when the speaker module works.
