Abstract

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include a circuit housing, an ear hook, a rear hook, a loudspeaker component, and a magnetic connector. The circuit housing may be configured to accommodate a control circuit or a battery component. The ear hook may be connected to one end of the circuit housing and at least partially covered by a first protective housing. The rear hook connected to another end of the circuit housing and at least partially covered by a second protective housing. The magnetic connector may be configured to absorb a charging interface of an external power source to establish an electrical connection so as to charge the loudspeaker apparatus.

First claim

We claim:

a loudspeaker component connected to one end of the ear hook, the loudspeaker component including an earphone core and an earphone core housing for accommodating the earphone core; and
a magnetic connector disposed on the circuit housing, wherein the magnetic connector is configured to charge the loudspeaker apparatus.

2. The loudspeaker apparatus of claim 1 , wherein the circuit housing includes a main side wall, an auxiliary side wall, and an end wall connected to each other, wherein the first protective housing and the second protective housing are coupled with each other on the main side wall and the auxiliary side wall.

3. The loudspeaker apparatus of claim 2 , wherein an inner surface of the first protective housing or the second protective housing corresponding to the main side wall is provided with a positioning convex, the positioning convex has a stripe shape and is arranged obliquely with respect to the auxiliary side wall, and an outer surface of the main side wall is provided with a positioning concave matching the positioning convex.

4. The loudspeaker apparatus of claim 2 , wherein a coupled region between the first protective housing and the second protective housing on the main side wall and the auxiliary side wall is arranged obliquely with respect to the auxiliary side wall.

5. The loudspeaker apparatus of claim 2 , wherein
the rear hook further comprises a plug end facing the circuit housing, the second protective housing is placed outside at least a portion the plug end;
the circuit housing includes a jack facing the rear hook, at least a portion of the plug end is inserted into the jack; wherein the plug end includes a slot that is perpendicular to an insertion direction of the plug end relative to the jack, and a first through hole corresponding to the slot position is disposed on a first side wall of the jack; and
the loudspeaker apparatus further comprises a fixing component, wherein the fixing component includes two pins disposed in parallel and a connecting part for connecting the pins; and the pins are inserted into the slot from outside of the plug end through the first through hole, so as to achieve a plug connection between the plug end and the jack.

6. The loudspeaker apparatus of claim 5 , wherein the jack further includes a second through hole opposite to the first through hole, the second through hole being disposed on a second side wall of the jack opposite to the first side wall of the jack, the pins being inserted into the second through hole through the slot.

7. The loudspeaker apparatus of claim 5 , wherein
the plug end comprises a first plug section and a second plug section;
a cross-section area of the first plug section is larger than that of the second plug section in a cross-sectional direction perpendicular to an insertion direction of the plug end;
the slot is disposed on the second plug section, and
the second plug section is inserted into the jack.

8. The loudspeaker apparatus of claim 7 , wherein the first plug section includes a first wiring duct extending along an insertion direction of the jack;
