Speaker structure
[0001]
The present invention relates to a speaker structure, and more particularly to a speaker structure
that effectively holds a diaphragm and vibrates in a well-balanced manner by a positioning ball
fixed to a sound output surface of a speaker unit.
[0002]
A conventional speaker structure is an electronic device that converts an electronic signal into an
audio signal.

Mainly, the voice coil is energized to generate a displacement force with the magnet, and by an
action resembling a piston, the diaphragm provided in front of the magnet is pushed to radiate
the sound wave in front of the diaphragm to the surroundings.
[0003]
Also, use a circular damper in the structure to fix the voice coil. However, since the damper is
disposed between the magnet and the diaphragm, the speaker can not be miniaturized, and can
not be applied to a lightweight and thin electronic product due to the limitation in volume.
[0004]
Currently, high-performance electronic products (for example, flat-screen TVs, laptop computers,
tablet computers, PDAs, MP3 players, mobile phones, etc.) are designed to be lightweight, thin
and easy to carry. Because the size is very small, the space for housing the speakers is limited.
Therefore, although the tablet type speaker was developed, in order to achieve weight reduction
and thickness reduction, there are some which the damper structure inside a tablet speaker was
abbreviate | omitted.
[0005]
In such a speaker, when outputting with a small power, a distortion phenomenon is unlikely to
occur because the vibration width of the diaphragm is small, but when outputting with a large
power, the vibration width of the diaphragm becomes large. Therefore, the diaphragm may
vibrate or shake unbalancely, and the sound output may become very unstable. For this reason,
conventional tablet speakers can only output at low power, and output at high power is limited.
[0006]
Therefore, when a structure or a speaker replacing the conventional damper structure vibrates
with high power drive, a speaker structure capable of stabilizing the audio output by effectively
positioning the diaphragm and vibrating it in a balanced manner has been desired. .
