## Abstract

A headphone includes a housing including a bottom wall portion and a side wall portion connected with the bottom wall portion which cooperate to form an accommodation space, a sealing ring, a microphone assembly including a sound guiding member configured to hold the sealing ring against a microphone and a support surface provided on a side of the side wall portion facing the accommodation space, and a positioning member inserted between the housing and the sound guiding member to enable the sound guiding member to remain the sealing ring in a press-hold condition. The sealing ring encircling the sound guiding hole provided on the support surface for connecting the accommodation space and an exterior of the housing is provided on a support surface. A sound guiding channel is provided on the sound guiding member for guiding a sound input from the sound guiding hole to the microphone.

### Claim 6 (depends on 5)

The headphone of claim 5, wherein
the sound guiding member further includes a catch block,
the catch block is located on the side of the main body portion back away from the bottom wall portion and spaced apart from the one or more first positioning portions along the pressing direction to cooperate with each other to form a first catch slot, and
the middle region of the positioning member is at least partially disposed within the first catch slot.

### Claim 7 (depends on 6)

The headphone of claim 6, wherein
in the vertical direction, a width of the catch block is smaller than a width of the main body portion,
a second catch slot is provided in the middle region of the positioning member, and
the catch block is provided in the second catch slot.

### Claim 8 (depends on 6)

The headphone of claim 6, wherein
the microphone is provided on a side of the main body portion facing the bottom wall portion,
a side of the one or more first positioning portions facing the support surface presses the sealing ring, and
the sound guiding channel extends to the main body portion via the one or more first positioning portions and the catch block.

### Claim 9 (depends on 8)

The headphone of claim 8, wherein
the microphone assembly further includes a lead wire connected to the microphone,
the side of the main body portion facing the bottom wall portion is further provided with a lead slot, and
the lead wire is provided within the lead slot.

### Claim 10 (depends on 5)

The headphone of claim 5, wherein
the housing further includes a guide portion disposed on the bottom wall portion, and
the guide portion is configured to guide the sound guiding member in the pressing direction.

### Claim 11 (depends on 10)

The headphone of claim 10, wherein
the guide portion is provided such that the sound guiding member tends to move toward the support surface and the bottom wall portion simultaneously or move away from the support surface and the bottom wall portion simultaneously.

### Claim 12 (depends on 1)
