COAXIAL AUDIO SPEAKER USING SINGLE AUDIO SOURCE

摘要

A disclosed coaxial audio speaker may include a treble sound unit and a bass sound unit co-axially surrounding the treble sound unit. The bass sound unit may be in form of a single magnetic gap mechanism and have a magnetic-conductive base. The magnetic-conductive base may be with an auxiliary magnetic adjoining space and a coil movement space adjacent to the auxiliary magnetic adjoining space. A magnet, a vibrating vocal tone diaphragm along with a wiring board may be disposed within the coil movement space. A bass vibration audio source point and a treble vibration audio source point may be at the same horizontal level. Therefore, the size of the audio speaker may be reduced. And the broader electricity adjustability may be achieved as the bass vibration audio source point and the treble vibration audio source point may be horizontally aligned.

主权项

1. A coaxial audio speaker comprising:
a treble sound unit with a treble vibration audio source point, a wiring board, and a treble sound hole; and a bass sound unit having:
a magnetic-conductive base with a center portion of the magnetic-conductive base defining a hollow treble positioning surface, and a main body of the magnetic-conductive base defining an auxiliary magnetic adjoining space and a vocal coil movement space adjacent to the auxiliary magnetic adjoining space and separated from each other by a separating wall;a ring-shaped magnet having a first surface and a second surface opposite to the first surface, the first surface being stationed within the vocal coil movement space, the ring-shaped magnet being fixed within the vocal coil movement space and away from the separating wall to form a magnetic gap between the ring-shaped magnet and the separating wall;a magnetic-conductive ring disposed on the second surface of the ring-shaped magnet and an opening defined by the magnetic-conductive ring and the magnetic-conductive base;a vibrating vocal tone diaphragm with a hollow diaphragm membrane on which a vocal coil is connected, a position where the vocal coil and the hollow diaphragm membrane connect defining a bass vibration audio source point, the vibrating vocal tone diaphragm being fixed within the opening to enclose the opening, and the vocal coil extending into the vocal coil movement space and positioned within the magnetic gap; anda wiring board adjoined on an external wall of a bottom surface defining the vocal coil movement space for positioning wires of the vocal coil; wherein the bass sound unit and the treble sound unit are coaxially disposed and the treble sound unit is adapted to be surrounded by the bass sound unit; wherein the bass vibration audio source point horizontally aligns with the treble vibration audio source point.
