Title:
ELECTROACOUSTIC TRANSDUCER
Document Type and Number:
Japanese Patent JP2017005486
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve a high resolution compact electroacoustic transducer (e.g., earphone, headphone) at a low cost, with simple configuration.SOLUTION: An electroacoustic transducer (e.g., earphone) 1 has a driver unit 20 and a high range enhancement circuit 26 housed in the housing 10. The driver unit 20 vibrates a diaphragm 23 by feeding an inputted audio signal to a coil 21, and converts the audio signal into sound. The high range enhancement circuit 26 is a circuit connected with the input side of the coil 21, resonating with the resonance frequency of a high frequency band for the inputted audio signal, and giving the audio signal to the coil 21 while boosting to a predetermined level. The high range enhancement circuit is constituted of a series resonance circuit of an inductor L having a predetermined inductance, and a capacitor C having a predetermined capacitance.SELECTED DRAWING: Figure 1
