Abstract

A speaker and a speaker-box using the same is provided in the present disclosure. The speaker includes a basket and a vibration system. The vibration system includes a diaphragm fixedly connected to the basket. The diaphragm includes a body part and a fixed part bent and extended from the edge of the body part to the basket, the basket includes a side wall encircling the receiving space, the side wall includes an upper surface opposite to the body part and an outer side surface extended from the outer edge of the upper surface, and the upper surface encircles an opening communicated with the receiving space; the body part covers the opening and is fixed with the upper surface, and the fixed part is extended along the outer side surface and fixed with the outer side surface.

First claim

What is claimed is:

1. A speaker-box, comprising a shell with an accommodating space and a speaker received in the accommodating space, the speaker comprising:
a basket with a receiving space; and
a vibration system, comprising a diaphragm fixedly connected to the basket and a voice coil for causing the diaphragm to vibrate and produce sound,
wherein the diaphragm comprises a body part and a fixed part, the body part comprises a dome, a meander part bent and extended from the edge of the dome, and a joint part extended from the edge of the meander part, the fixed part is bent and extended from the edge of the joint part;
the basket comprises a side wall encircling the receiving space, the side wall comprises an upper surface opposite to the body part and an outer side surface extended from the outer edge of the upper surface, and the upper surface encircles an opening communicated with the receiving space;
the body part covers the opening and the joint part thereof is fixed with the upper surface, and the fixed part is extended along the outer side surface and fixed with the outer side surface;
a front sound cavity is formed between the shell and the diaphragm, a baffle plate is fixed in the shell, the baffle plate and the shell form a sound outlet channel communicated with the front sound cavity, the baffle plate abuts the fixed part and is bonded and fixed with the fixed part.

2. The speaker-box as described in claim 1 , wherein the vibration system further comprises a reinforcing plate overlapped to one side of the dome away from the receiving space.

3. The speaker-box as described in claim 1 , wherein the speaker further comprises a magnetic circuit system received in the receiving space, the magnetic circuit system comprises a magnet set, the magnet set comprises a main magnet and secondary magnets symmetrically disposed on two sides of the main magnet, a magnetic gap is formed between the main magnet and the secondary magnets, one end of the voice coil is fixed with the dome, and the other end of the voice coil is inserted into the magnetic gap.
