## Abstract

Disclosed is a mounting assembly for use in a mobile terminal. The mobile terminal includes a main frame on which a motherboard is mounted. The mounting assembly includes a rack for mounting thereon at least one of a speaker or a vibrator, and the rack is detachably connectable to the main frame. By means of the mounting assembly, the speaker or the vibrator is not directly mounted on the motherboard of the mobile terminal.

## Claims

### Claim 1

A mounting assembly for use in a mobile terminal, the mobile terminal comprising a main frame on which a motherboard is mounted, the mounting assembly comprising:
a rack for mounting thereon at least one of a speaker or a vibrator, the rack comprising:
a sub-frame portion extending along at least a portion of an outline of the main frame and having an engaging surface for detachably connecting to the main frame; and
a connecting portion extending inwardly from an inner side wall of the sub-frame portion to provide a mounting area for the at least one of the speaker or the vibrator; and
a cushion for providing buffering between the sub-frame portion and the main frame,
wherein the rack is detachably connectable to the main frame, and
wherein the cushion is arranged to extend along the engaging surface of the sub-frame portion.

### Claim 2 (depends on 1)

The mounting assembly of claim 1, wherein the cushion comprises a plurality of sections having different thicknesses from each other.

### Claim 3 (depends on 2)

The mounting assembly of claim 2, wherein the sub-frame portion is arranged such that the engaging surface is conformal to the cushion.

### Claim 4 (depends on 1)

The mounting assembly of claim 1, wherein the sub-frame portion further has an end surface opposite to the engaging surface in a thickness direction and engageable with a rear cover of the mobile terminal, and wherein the connecting portion extending inwardly from a position between the end surface and the engaging surface on the inner side wall of the sub-frame portion so that the at least one of the speaker or the vibrator mounted on the connecting portion is suspended in a space between the rear cover and the main frame when the rear cover is engaged with the end surface.

### Claim 5 (depends on 1)

The mounting assembly of claim 1, wherein the sub-frame portion extends along an outline of the main frame to form a closed annular structure.

### Claim 6 (depends on 5)

The mounting assembly of claim 5, wherein the connecting portion extends in a plane defined by the annular structure to cover the annular structure.

### Claim 7 (depends on 6)

The mounting assembly of claim 6, wherein the sub-frame portion further has an end surface opposite to the engaging surface in a thickness direction, and wherein the connecting portion is arranged such that an outer surface of the connecting portion meets the end surface of the sub-frame portion.

### Claim 8 (depends on 7)

The mounting assembly of claim 7, wherein the sub-frame portion and the connecting portion are integrally formed such that the rack can serve as a rear cover of the mobile terminal.

### Claim 9 (depends on 1)

The mounting assembly of claim 1, wherein the connecting portion is made of an elastic material.

### Claim 10 (depends on 1)

The mounting assembly of claim 1, further comprising the at least one of the speaker or the vibrator.

### Claim 11 (depends on 1)

The mounting assembly of claim 1, further comprising a connecting electrode for providing an electrical connection between the motherboard and the at least one of the speaker or the vibrator.

### Claim 12 (depends on 1)

The mounting assembly of claim 1, wherein the rack is detachably connectable to the main frame by means of at least one selected from the group consisting of screwing and snap-fitting.

### Claim 13 (depends on 1)

A mobile terminal comprising the mounting assembly as claimed in claim 1.

### Claim 14 (depends on 2)

A mobile terminal comprising the mounting assembly as claimed in claim 2.
