Along with the develop rapidly of electronic technology, portable electric appts is widely used, and speaker unit is the important component part of electronics in standby as acoustical device.Speaker unit generally includes housing and is contained in the interior loudspeaker monomer of housing, and speaker unit also comprises the coupling assembling that is electrically connected with external circuit, and coupling assembling comprises the conducting strip that is injected into one with the second housing, and conducting strip is metal clips.Because the inner space of portable electric appts is less, for mutual interference does not occur between each parts, just need to leave certain non-metallic regions between each parts.The second housing of speaker unit of the prior art is provided with the sidewall of being combined with the first housing in a side that is injected with conducting strip.Conducting strip need to be fixed when determining injection moulding by Shooting Technique, so conducting strip just must have the fixed position that protrudes from the second housing, again with the fixed position excision of outstanding the second housing of conducting strip, this is just so that conducting strip will extend to the edge of the second housing always after injection moulding finishes.The metallic region of the speaker unit of this structure is larger, and this is easy to produce interference just so that other parts of speaker unit and electronic equipment between (such as antenna etc.), thereby has reduced functional reliability and the stability of electronic equipment.
The utility model content
The utility model provides a kind of speaker unit for above deficiency technical problem to be solved, and the metallic region of this speaker unit is little, so that functional reliability and the stability height of the utility model speaker unit have been installed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of speaker unit, comprise the first housing and the second housing that combine, and contain loudspeaker monomer in the cavity that described the first housing and the second housing surround; Described speaker unit also comprises be used to the coupling assembling that is electrically connected described loudspeaker monomer and external circuit, described coupling assembling comprises the conducting strip that is injected into one with described the second housing, the side at the corresponding described conducting strip of described the second housing edge is provided with groove, the position of corresponding described groove is provided with retaining wall on described the first housing, and described retaining wall and described groove are suitable.
As a kind of improvement, described coupling assembling also comprises the spring that is connected with described conducting strip, and described spring connects described external circuit.
As further improvement, described retaining wall near a side of described spring be provided with described spring suitable dodge groove.
The beneficial effects of the utility model are: the utility model speaker unit comprises for the coupling assembling that is electrically connected loudspeaker monomer and external circuit, coupling assembling comprises the conducting strip that is injected into one with the second housing, the side that the second housing is injected with conducting strip is provided with groove, the position of respective slot is provided with retaining wall on the first housing, and retaining wall and groove are suitable.Because the side at the corresponding conducting strip of the second housing edge is provided with groove, so that conducting strip can only extend to groove, again since the first housing be provided with the second housing on the suitable retaining wall of groove, retaining wall adopts the plastic material identical with the first housing to make, in the non-metallic regions that has played between other parts that increased speaker unit and electronic equipment when connecting the first housing and the second housing, thereby reduced to occur between other parts of speaker unit and electronic equipment the possibility disturbed, improve functional reliability and stability that the electronic equipment of the utility model speaker unit is installed, promoted the overall performance of electronic equipment.
In sum, the utility model speaker unit has solved the large technical problem of metallic region between other parts of speaker unit and electronic equipment in the prior art.Metallic region between other parts of the utility model speaker unit and electronic equipment is little, so that functional reliability and the stability height of the utility model speaker unit have been installed, has promoted the overall performance of electronic equipment.
