Abstract

The utility model discloses a loudspeaker apparatus comprising a housing and a loudspeaker unit accommodated in the housing. The housing comprises a first housing and a second housing which are combined together. A combined side surface of the first housing and the second housing is provided with a sound outlet hole used for sounds to come out. The loudspeaker unit comprises a magnetic circuit system and a vibration system. The vibration system comprises a vibration diaphragm. The vibration diaphragm is fixed between the first housing and the second housing. Furthermore, a limiting block used for fixing the vibration diaphragm is arranged at a position, corresponding to the phonating hole, on the second housing. A groove is arranged at a position on the first housing which is corresponding to the limiting block. The loudspeaker apparatus of the utility model is advantageous in being large in sound outlet hole space and good in acoustics performance.

Description

Speaker unit

Technical field

The utility model relates to the electroacoustic field, especially relates to a kind of speaker unit.

Background technology

Along with the expansion in consumer electronics market, consumer electronics products such as a large amount of mobile phones, notebook computer are used widely, and as acoustic element important in the consumer electronics product, the Microspeaker device has demand widely.Along with the raising that people require consumer electronics product, the acoustical behavior of Microspeaker device more and more is subjected to people's attention.

Speaker unit generally includes first housing and second housing that are combined as a whole, and is contained in the loudspeaker unit in the cavity that first housing and second housing surround; Loudspeaker unit involving vibrations system and magnetic circuit system, vibrational system comprises vibrating diaphragm, when assembling is finished, first housing and second housing need be combined as a whole, vibrating diaphragm is fixed between first housing and second housing.In the prior art, between loud speaker first housing and second housing fixedly the structure of vibrating diaphragm mainly be: fixedly be useful on the fixedly support ring of vibrating diaphragm at the inside projection end face of second housing sidewall, support ring is becket, and the vibrating diaphragm overlapping edges is on support ring.In side is spoken loadspeaker structure, adopt support ring fixedly vibrating diaphragm the mode support ring easily to phonate hole generation block, the speaker unit sound performance is caused adverse effect.

Therefore, be necessary to propose to improve, to overcome prior art loadspeaker structure shortcoming.

The utility model content

It is big that technical problem to be solved in the utility model provides space, a kind of hole, the speaker unit that acoustical behavior is good.

To achieve these goals, the utility model is by the following technical solutions:

A kind of speaker unit comprises housing and is contained in the interior loudspeaker unit of described housing; Described housing comprises first housing and second housing that combines, and the side that described first housing is combined with described second housing is provided with the phonate hole for the sound outgoing; Described loudspeaker unit comprises magnetic circuit system and vibrational system, and described vibrational system comprises vibrating diaphragm, and described vibrating diaphragm is fixed between described first housing and described second housing; And: the corresponding described phonate hole of described second housing position is provided with the guide vane end stop of fixing described vibrating diaphragm, and the corresponding described guide vane end stop of described first housing is provided with groove.

As a kind of optimized technical scheme, described guide vane end stop is a plurality of.

As a kind of optimized technical scheme, described loudspeaker unit is two, and described vibrating diaphragm also is two, and the corresponding described phonate hole of described second housing position is provided with two parts guide vane end stop of fixing described two vibrating diaphragms.

The utility model speaker unit, a side of first housing and the second housing combination is provided with phonate hole, corresponding phonate hole position arranges guide vane end stop on second housing, be used for fixedly vibrating diaphragm, the corresponding guide vane end stop of first housing is provided with groove, avoid the blocking of phonate hole improved the phonate hole space, thereby improve the acoustical behavior of speaker unit.

Embodiment

Below in conjunction with accompanying drawing, describe the utility model concrete structure in detail.

Speaker unit as shown in Figure 1 is a specific embodiment of the utility model speaker unit.As shown in Figure 2, the speaker unit of present embodiment comprises housing, and housing comprises first housing, 11, the second housings 12 and the 3rd housing 13 that combines; Be provided with loudspeaker unit in the cavity that first housing 11, second housing 12 and the 3rd housing 13 surround, loudspeaker unit comprises magnetic circuit system 5, arrangements of electric connection 4 and vibrational system, vibrational system comprise vibrating diaphragm 2 and are fixed in vibrating diaphragm 2 away from the voice coil loudspeaker voice coil 3 of first housing, 11 1 sides; Magnetic circuit system 5 is provided with magnetic gap, voice coil loudspeaker voice coil 3 is arranged in magnetic circuit system 5 magnetic gap, voice coil loudspeaker voice coil 3 is electrically connected with arrangements of electric connection 4, external electric signal enters voice coil loudspeaker voice coil 3 by arrangements of electric connection 4, the voice coil loudspeaker voice coil 3 that is arranged in magnetic circuit system 5 magnetic gap is subjected to magnetic field force because foreign current changes, voice coil loudspeaker voice coil 3 vibrations, voice coil loudspeaker voice coil 3 vibrations of being fixed on the vibrating diaphragm 2 drive vibrating diaphragm 2 vibration soundings.

As shown in Figure 3, vibrating diaphragm 2 is fixed between first housing 11 and second housing 12, first housing 11, second housing 12 and the 3rd housing 13 are in conjunction with the formation housing is set, housing one side is provided with the phonate hole 6 for the sound outgoing in the position of

first housing

11 and 12 combinations of second housing, be arranged at the voice coil loudspeaker voice coil 3 magnetic field force induced vibrations in magnetic circuit system 5 magnetic gap, drive vibrating diaphragm 2 vibration soundings, the sound that sends is by phonate hole 6 outgoing.Fixedly the support ring of vibrating diaphragm is to the blocking of phonate hole for fear of traditional structure, and as shown in Figure 3, corresponding phonate hole 6 positions are provided with for the fixing guide vane end stop 121 of vibrating diaphragm 2 on the utility model speaker unit second housing 12.As shown in Figure 4, guide vane end stop 121 is the block-shaped protrusion that arranges on second shell 12, can not produce the large tracts of land bar shaped to second shell, 12 relevant positions and not block, and can increase the space of phonate hole 6 among Fig. 6, avoids phonate hole 6 produced blocking.As shown in Figure 5, on first housing 11, be provided with and expect the groove 111 that forms, guide vane end stop 121 among groove 111 corresponding diagram 3 and Fig. 4 on second housing 12 arranges, corresponding guide vane end stop 121 is provided with groove 111 and can further improves the phonate hole space on first housing 11, improves the acoustical behavior of speaker unit.
