## Abstract

A microphone includes a base seat, a tube unit connected the base seat, a sound head, and a cable. The base seat includes a surrounding wall that is formed with at least one through hole, and a base wall that cooperates with the surrounding wall to define a receiving space therebetween, and that has a conical surface for reflecting sound waves toward the through hole. The sound head is disposed in the receiving space, and is spaced apart from the base wall of the base seat. The cable is electrically connected to the sound head and extends through the tube unit.

## Claims

### Claim 1

A microphone comprising:
a base seat including
a surrounding wall that is formed with at least one through hole, and
a base wall that cooperates with said surrounding wall to define a receiving space therebetween, and that has a conical surface for reflecting sound waves toward said through hole;
a tube unit connected to said base seat;
a sound head disposed in said receiving space of said base seat, and spaced apart from said base wall of said base seat; and
a cable electrically connected to said sound head, and extending through said tube unit;
wherein said tube unit includes a flexible tube seat connected to said base seat, and having an outer surrounding surface that is formed with at least one surrounding groove;
wherein said base seat further includes a linking wall connected to said surrounding wall and formed with a first cable hole, said tube unit further including an end tube seat, said flexible tube seat being disposed between said end tube seat and said base seat, said flexible tube seat of said tube unit being formed with a second cable hole, said second cable hole being in spatial communication with said first cable hole and having a first engaging hole section engaged with said linking wall of said base seat, said cable extending through said first and second cable holes; and
wherein said tube unit further includes a cable tube coupled to said end tube seat, and having an inner tube wall that defines a third cable hole, and an outer tube wall that is sleeved on said inner tube wall, said third cable hole being in spatial communication with said second cable hole, said second cable hole further having a second engaging hole section that is spaced apart from said first engaging hole section, said end tube seat having an abutment portion that abuts against said flexible tube seat, and an engaging portion that engages non-rotatably said second engaging hole section of said second cable hole.

### Claim 2 (depends on 1)

The microphone as claimed in claim 1, wherein said conical surface of said base wall of said base seat tapers toward said sound head.

### Claim 3 (depends on 1)

The microphone as claimed in claim 1, wherein said end tube seat further has:
a coupling passage, said cable tube extending through said coupling passage;
at least one adhesive-receiving hole formed in said engaging portion and being in spatial communication with said coupling passage; and
an adhesive filled in said at least one adhesive-receiving hole for bonding said flexible tube seat and said cable tube.

### Claim 4 (depends on 3)

The microphone as claimed in claim 3, further comprising a surrounding screen that is disposed in said receiving space and that corresponds in position to said at least one through hole, an end cap that is coupled to said surrounding wall and opposite to said base wall, and an end screen that is disposed between said end cap and said surrounding wall.

### Claim 5 (depends on 2)

The microphone as claimed in claim 2, wherein said end tube seat further has:
a coupling passage, said cable tube extending through said coupling passage;
at least one adhesive-receiving hole formed in said engaging portion and being in spatial communication with said coupling passage; and
an adhesive filled in said at least one adhesive-receiving hole for bonding said flexible tube seat and said cable tube.

### Claim 6 (depends on 5)

The microphone as claimed in claim 5, further comprising a surrounding screen that is disposed in said receiving space and that corresponds in position to said at least one through hole, an end cap that is coupled to said surrounding wall and opposite to said base wall, and an end screen that is disposed between said end cap and said surrounding wall.
