Abstract

A diaphragm type sound source output device. More than one bugle monomer or cladding bugle monomer is set at any side of the sound source output device, and more than one diaphragm is set at any place or multi places of the inner side or the outer side of the sound source output device, or the binders combined with diaphragms are set at any place or multi places of the inner side or the outer side of the sound source output device. The diaphragms can experience the oscillation of the sound when the bugle monomer of the sound source output device emits sound, thereby generating acoustic resonance in the sound source output device. The bass becomes softer and the broadness of the diapason is effectively increased through using the diaphragm set in the sound source output device.

Description

DIAPHRAGM TYPE SOUND SOURCE OUTPUT DEVICE
BACKGROUND
1. Field of the invention [001] The present invention relates to a diaphragm type sound source output device and, more particularly, to an audio output apparatus with at least one soft or elastic diaphragm positioned at any or more places of an inner side and an outer side thereof so as to have efficacies such as softer undertone and wider diapason.
2. Description of the prior art [002] At present, there are various speakers in the market. A known speaker generally includes a speaker box and at least one speaker unit positioned at the front side of the speaker box. When the speaker unit begins to work, it can release the sound and the consumer can thereby listen to various music styles.
[003] However, most of the speaker boxes purchased by the consumer cannot exert the sound effectively via the known structures and cannot generate resonance of the sound. Also, the diapason of the sound of the speaker boxes is not wide enough. Therefore, the consumer cannot obtain high-grade feeling in listening, though a lot of money has been spent.
[004] What is needed, therefore, is an improved diaphragm type sound source output device.
BRIEF SUMMARY
[005] A diaphragm type sound source output device according to an embodiment of the present invention includes an audio output device, at least one speaker unit, and at least one diaphragm. The at least one speaker unit is positioned at any side of the audio output device.
The speaker unit can be an embedded speaker unit. The at least one diaphragm can be positioned at any or more places of an inner side and an outer side of the audio output device.

.

Alternatively, a combined part combining the diaphragm can be positioned at any or more places of the inner side and the outer side of the audio output device. When the speaker unit of the audio output device releases sound, the diaphragm positioned on the audio output device can get vibration of the sound so that an inside of the audio output device can generate resonance. Thus, the audio output device can increase bass frequency bandwidth to generate softer undertone and increase overall sound frequency range to generate wider diapason.
[006] These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying drawings.
