AI Technical Summary
Technical Problem
Existing electrodynamic speakers suffer from excessively large ∆T when the pulse signal stops, affecting sound quality. Furthermore, small signal reproduction is limited, making it difficult to improve sound quality.
Method used
The digital speaker drive system uses a specifically connected co-fired ferrite and iron-rich conductor, a field-effect transistor switch drive circuit, and a capacitor and resistor network. The simple and reliable circuit structure is designed to reduce ∆T and improve small signal reproduction.
Benefits of technology
Without changing the speaker structure and materials, ∆T is reduced, sound quality is improved, applicability is enhanced, and system stability and reliability are improved.

Abstract
The present invention relates to a digital speaker drive system, characterized by comprising a first connection terminal, a second connection terminal, a power supply terminal, a ground terminal, a speaker, a first ferrite and iron-rich conductor co-fired body, a second ferrite and iron-rich conductor co-fired body, a third ferrite and iron-rich conductor co-fired body, a first field-effect transistor switch drive circuit, a second field-effect transistor switch drive circuit, a first N-channel field-effect transistor, a second N-channel field-effect transistor, a first diode, a second diode, and the like. The speaker is provided with a forward winding and a reverse winding, respectively. This invention can reduce ΔT without changing the existing structure and materials of the speaker, and can also compensate for the defect of existing power switching tubes in reproducing small signals during use. This can significantly improve the sound quality of electrodynamic digital speakers. Furthermore, the overall circuit structure of the digital speaker drive system has the advantages of simplicity, reliability, and good stability.
