The invention discloses a speaker. The speaker includes a housing, a magnetic circuit system and a vibration system. The vibration system has a diaphragm and a voice coil. The housing includes a front cover and a frame. The diaphragm has a dome, a suspension and a fixing portion. The frame includes a first connecting wall and a second connecting wall extending from the first connecting wall. The front cover includes a third connecting wall and a fourth connecting wall. The fixing part includes a first fixing portion sandwiched between the first connecting wall and the third connecting wall and a second fixing part sandwiched between the second connecting wall and the fourth connecting wall. By virtue of the configuration, the speaker is provided with better waterproof performance and higher sensitivity.
1. A speaker comprising:
a housing with accommodating space formed by a front cover and a frame engaging with the front cover;
a magnetic circuit system accommodated in the accommodating space;
a vibration system accommodated in the accommodating space, including a diaphragm assembled with the housing and a voice coil connected with the diaphragm for driving the diaphragm to vibrate for radiating sound;
the diaphragm comprising a dome portion located at a middle position thereof, a suspension surrounding the dome portion and a fixing portion surrounding the suspension;
the frame comprising a first connecting wall close to the voice coil and a second connecting wall extending obliquely from the first connecting wall along a direction away from the accommodating space;
the front cover comprising a third connecting wall engaging with the first connecting wall and a fourth connecting wall engaging with the second connecting wall; wherein
the fixing portion comprises a first fixing portion sandwiched between the first connecting wall and the third connecting wall, and a second fixing portion sandwiched between the second connecting wall and the fourth connecting wall;
wherein the frame further comprises a fifth connecting wall extending from the second connecting wall along a direction away from the accommodating space, the front cover further comprises a sixth connecting wall engaging with the fifth connecting wall; the fixing portion further comprises a third fixing portion sandwiched between the fifth connecting wall and the sixth connecting wall.
2. The speaker as described in claim 1 , wherein the second connecting wall extends obliquely from the first connecting wall along a direction away from the accommodating space and away from the front cover.
3. The speaker as described in claim 1 , wherein the fifth connecting wall horizontally extends from an edge of the second connecting wall along a direction away from the accommodating space.
4. The speaker as described in claim 1 , wherein the fixing portion further comprises a connecting part for connecting the first fixing portion and the suspension.
