Abstract

An earbud includes a connection member, a regulating valve, an earbud body and a bladder. The connection member includes opposite first and second ends and defines a through hole extending through the first end and the second end. The regulating valve defines a flow channel therein and incudes a connection end and a working end. The connection end is tightly connected to the connection member, and the working end defines a flat adjustment opening. The flow channel communicates with the through hole of the connection member. The earbud body is mounted around the regulating valve and connected tightly to the connection member or the regulating valve. The earbud body defines a first cavity therein, and the bladder is tightly connected to the connection member and defines a second cavity for containing fluid therein. The second cavity communicates with the through hole of the connection member.

Dependent claims

An earbud, comprising:

a connection member comprising opposite first end and second end and defining a through hole therein, the though hole extending through the first end and the second end;
a regulating valve defining a flow channel therein and comprising a connection end and a working end, the connection end tightly connected to the connection member, the working end defining a flat adjustment opening, the flow channel communicating with the through hole of the connection member;
an earbud body mounted around the regulating valve and connected tightly to the connection member or the regulating valve, the earbud body defining a first cavity therein;
and
a bladder tightly connected to the connection member and defining a second cavity for containing fluid therein, the second cavity in communication with the through hole of the connection member;
when the earbud is in a natural state, the flat adjustment opening is in a closed state to prevent the first cavity from communicating with the flow channel;
when the bladder is compressed, the fluid flows from the second cavity, passes through the through hole and the flow channel, pushes open the flat adjustment opening and enters the first cavity to make the earbud body expand;
when the fluid stops to enter the first cavity via the flat adjustment opening, the flat adjustment opening reverts to the closed state to prevent backflow of the fluid from the first cavity into the flow channel;
and
when the working end of the regulating valve is compressed to open the flat adjustment opening, the fluid flows back from the first cavity, passes through the flat adjustment opening, the flow channel and the through hole and returns to the bladder, so as to make the earbud body to contract to its natural state.

An earbud, comprising:

an earbud body configured for inserting into an ear canal, the earbud body defining a first cavity therein;
a bladder defining a second cavity for accommodating fluid therein;
and
a regulating valve comprising a connection end and an elastic working end, the connection end communicating with the second cavity of the bladder, the elastic working end defining an adjustment opening facing towards the first cavity of the earbud body;
when the earbud is in the natural state, the adjustment opening is closed to disconnect the first cavity from the second cavity;
when the bladder is compressed to open the adjustment opening, the fluid flows from the second cavity to the first cavity via the adjustment opening, so that the earbud body expands to attach to the ear canal;
and
when the earbud body is compressed to open the adjustment opening, the fluid flows back from the first cavity to the second cavity via the adjustment opening, so that the earbud body recovers to its natural state;
wherein a hollow connection member is arranged between the bladder and the regulating valve, one end of the hollow connection member is connected to the bladder and communicates with the second cavity, the other end of the hollow connection member is connected to and communicates with the connection end of the regulating valve, and the elastic working end extends into the first cavity of the earbud body;
and
wherein the earbud body is mounted around the regulating valve and has an open end connected to the other end of the hollow connection member, the bladder comprises an open end connected to the one end of the hollow connection member, and a snap member is mounted around the open ends of the earbud body and bladder for fixing the earbud body and bladder together.
