Piezoelectric Ceramics Dual Band Bass Enhanced Earphone
[0001]
The present invention relates to the field of earphone audio, and more particularly, to an
earphone that combines a piezoelectric ceramic speaker assembly and a dynamic coil speaker

Basically, a dynamic coil type earphone connects a cylindrical coil in a permanent magnetic field,
that is, a voice coil to a diaphragm. The voice coil generates a magnetic field under the drive of
the signal current, acting alternately with the magnetic force of the permanent magnetic field to
move the diaphragm to vibrate. Audio is transmitted to a voice coil through an audio cable,
converted to sound waves of audio frequency, and output.
[0003]
Generally, in consideration of versatility and cost, a diaphragm that can usually resolve the full
range is employed. The advantage is that the frequency band to be generated is wide, but the
resolution effect of the high tone range and the low range is relatively poor, and the position of
voice, response and sense of three-dimensional space can not be clearly resolved.
[0004]
As the number of gaming applications on mobile phones and tablets has increased, the demand
for the player's earphone resolution effect has also increased, and usually a bass enhanced effect
is expected. To meet these needs, the market uses a combination of a bass voice coil and a treble
voice coil, but since the whole vibration is also by one diaphragm, a clear resolution effect can
not be achieved. For this reason, while solving the above-mentioned problem and improving
resolution of a specific frequency band, it is required to achieve the hearing effect which
intensified the bass.

enhanced earphone.
