[technical field]
The utility model relates to a kind of speaker unit, relates in particular to a kind of location division of speaker unit.
[background technology]
In recent years along with the fast development of mobile communication technology, the consumer uses the mobile communication equipment that has phonetic function more and more, for example portable phone, handheld device, laptop computer, laptop computer, multimedia player and can be by other equipment public or that dedicated communications network communicates.And loud speaker is as the playing device of voice, and voice quality that it is inner and the collocation of external hardware all are subjected to people's attention extraordinarily.
Loud speaker needs in the inside of mobile phone to be connected to transmit signal with fixed clients, and being connected of loud speaker and client for convenience, usually loud speaker is placed in the housing, form a speaker unit, speaker unit is fixedlyed connected with external client by housing.And nowadays, when speaker unit is connected with client, need to apply a large amount of two-sided tapes or at the two ends of bottom reference column is set in the bottom of speaker housings, so be provided with, not only make troubles, and locating effect is firm inadequately to assembling; Simultaneously, understand the size of the back cavity of limiting loudspeaker, thereby influence the Frequency Response of loud speaker.
Therefore, be necessary to provide a kind of new speaker unit to solve the problems referred to above.
[utility model content]
The technical problem that the utility model need solve is to provide a kind of speaker unit that can fixedly connected with external client well.
According to the above-mentioned technical problem that needs solution, designed a kind of speaker unit, comprise: a kind of speaker unit, comprise: be provided with the housing of host cavity and be contained in the interior loudspeaker unit of host cavity, wherein, described housing is provided with positioning table and centers on the brace table of this positioning table, described positioning table is provided with towards first inner surface of loudspeaker unit and first outer surface relative with first inner surface, described brace table is provided with towards second inner surface of loudspeaker unit and second outer surface relative with second inner surface, described first outer surface protrudes in second outer surface and makes housing become ladder-type structure outside housing, and the vertical range of the relative loudspeaker unit of first inner surface is greater than the vertical range of the relative loudspeaker unit of second inner surface.
As a kind of improvement of the present utility model, described housing comprises that upper shell reaches and the lower house of upper shell winding, and described positioning table is positioned on the lower house.
As a kind of improvement of the present utility model, described upper shell is provided with accepting hole, and described loudspeaker unit comprises magnetic circuit system and vibrational system, and described magnetic circuit system and vibrational system are contained in the accepting hole.
As a kind of improvement of the present utility model, described first inner surface and second inner surface are parallel to each other.
As a kind of improvement of the present utility model, described positioning table is square along being shaped as of the cross section of parallel and first inner surface.
The utlity model has following advantage: owing on speaker unit, be provided with the positioning table of fixedlying connected with external client, thereby, not only make the back of the body chamber ratio of loud speaker increase in the past, its acoustical behavior is increased; Can also strengthen the intensity that speaker unit is connected with external client, make the location between the two more firm.In addition, also can reduce accessory cost unnecessary in the production.
[description of drawings]
Fig. 1 is the schematic perspective view of the utility model speaker unit.
Fig. 2 is the generalized section of the utility model speaker unit.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, the utility model speaker unit 10 comprises the housing 100 that is provided with host cavity 110 and is contained in loudspeaker unit 200 in the host cavity 110.Wherein, housing 100 is provided with the positioning table 150 that is connected with external client.
In the present embodiment, housing 100 comprises that upper shell 101 reaches and the lower house 102 of upper shell 101 windings, and upper shell 101 is provided with the accepting hole (not marking) that is complementary with loudspeaker unit 200 shapes.Loudspeaker unit 200 comprises magnetic circuit system and driven by magnetic circuit system and the vibrational system of generation vibrating effect that described magnetic circuit system and vibrational system are contained in the accepting hole of upper shell 101.The bottom of lower house 102 is provided with positioning table 150 and centers on the brace table 160 of positioning table 150.Positioning table 150 is provided with towards first inner surface 151 of loudspeaker unit 200 and first outer surface 152 relative with first inner surface 151 and that be connected with external client; Described brace table 160 is provided with towards second inner surface 161 of loudspeaker unit 200 and second outer surface 162 relative with second inner surface 161, described first outer surface 161 protrudes in second outer surface 162 outside housing, and makes positioning table 150 and brace table 160 be interconnected to ladder-type structure.Preferably, positioning table 150 is square along being shaped as of the cross section of parallel and first inner surface 151, and described first inner surface 151 and second inner surface 161 are parallel to each other.
The vertical range of first inner surface, the 151 relative loudspeaker units 200 of positioning table 150 is greater than the distance of the vertical direction of described second inner surface, 161 relative loudspeaker units 200.Like this, will strengthen the bottom of housing 100 and the space length of loudspeaker unit 200, the distance that is the phonate hole of housing bottom and loudspeaker unit 200 becomes big, so, can increase the back cavity of loudspeaker unit 200, its frequency response curve of sounding is improved, thereby improve the Frequency Response of whole speaker unit 10.
To sum up, owing on speaker unit, be provided with the positioning table of fixedlying connected with external client, thereby, not only make the back of the body chamber ratio of loud speaker increase in the past, its acoustical behavior is increased; Can also strengthen the intensity that speaker unit is connected with external client, make the location between the two more firm.In addition, also can reduce accessory cost unnecessary in the production.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
