Description

Micro-audio and LED lighting fixtures

The present invention relates to a miniature acoustic device and an LED lamp for use thereof, and particularly relates to an effect that enables the air pressure generated by the diaphragm to be vented from the speaker when the speaker unit is actuated, thereby improving the low frequency sound, and can be applied to the LED. Micro-audio on table lamps, ceiling lamps or recessed lights.

Nowadays, the micro-speaker (speaker unit) applied to a computer screen, a notebook computer or other electronic devices, the conventional technology directly installs the micro-speaker in the above-mentioned electronic device, but the lack of the speaker structure will cause the sound quality to be distorted. Therefore, it is common to use a full-range speaker unit and install a full-range speaker unit in a closed-type speaker, so that the chamber inside the speaker is isolated from the outside air, thus enhancing the sound quality of the high-range. However, in a fully enclosed speaker, when the speaker unit is actuated, the pressure inside the speaker chamber cannot be vented, which hinders the diaphragm from acting, resulting in poor bass performance (sound turbidity).

In addition, today's mobile phones usually have more than two speakers, one of which is inside the front, as a receiver for a mobile phone, which emits a lower volume, which is suitable for listening to the ear, and the other is in action. The back of the phone or other selected location, as a speaker ringtone or multimedia player. As can be seen from the above, today's mobile phones are equipped with two More than one speaker, in addition to causing its manufacturing cost is not easy to reduce, can not save space inside the mobile phone, and thus it is not easy to reduce the size of the mobile phone, in the market environment where the mobile phone is more compact, the conventional two speakers Technology will be very disadvantageous.

The main purpose of this creation is to provide a micro-sound that improves the poor sound quality caused by conventional micro-enclosed speakers, and the problem that conventional electronic devices require dual speakers, and can reduce the cost and increase the space inside the mobile device.
