Description

Loudspeaker mould group

Technical field

The present invention relates to electroacoustic conversion art more particularly to a kind of loudspeaker mould groups.

Background technique

With the arrival of mobile internet era, the update of electronic product is getting faster, and people are to electronic product The requirement of various aspects of performance is also higher and higher, one of them is the music function of high-quality, and therefore, electroacoustics system needs continuous Improving performance, the loudspeaker mould group of high-quality be realize this high-quality music function one of necessary condition.

Loudspeaker mould group generally includes the loudspeaker monomer of shell and receiving inside the shell, and wherein shell includes shell and lid Body.When assembling, after being initially charged with loudspeaker monomer, shell and cover cap are connect, complete assembling.In the prior art, shell and lid When being sealed, glue in the gap between shell and lid is needed, or completion is fetched by supersonic welding.

Glue and the sealing process of ultrasonic bonding influence production efficiency, and corresponding equipment is needed to consume.

Therefore, it is really necessary to provide the new loudspeaker mould group of one kind to solve the above problems.

Summary of the invention

The present invention in order to solve the above technical problems, and a kind of novel loudspeaker mould group is provided, the specific scheme is that

There is provided a kind of loudspeaker mould group comprising shell connects the lid for surrounding accommodating space and receiving with the case lid Loudspeaker monomer in the accommodating space, the shell include bottom wall and prolong from the bottom wall towards lid direction bending The side wall stretched, the side wall include the upper surface and being recessed from the upper surface to bottom wall direction far from the bottom wall to be formed it is recessed Slot, the lid are contained in the groove, and silica gel, the lid and institute are arranged between the side of the lid and the groove Stating sidewall extrusion silica gel engages the lid with the housing seal.

Preferably, the silica gel is hollow ring, and the silica gel is wound around the side of the lid.

Preferably, the silica gel includes main part and corner portion, and the chamfer site is raised in the main part close to described The periphery of sound device monomer side.

Preferably, the silica gel and the lid double-shot moulding are integrally formed.

Preferably, the silica gel and the lid are glued.

Preferably, the silica gel is hollow ring, and the silica gel is arranged in the groove.

Preferably, the silica gel and the shell double-shot moulding are integrally formed.

Preferably, the silica gel and the shell are glued.

Preferably, interval forms first operatic tunes between the loudspeaker monomer and the bottom wall, and the side wall is correspondingly arranged There is at least one being connected with first operatic tunes to go out acoustic aperture, the loudspeaker monomer and the lid, is formed between shell Second operatic tunes opposite with first operatic tunes.

It is squeezed by the way that silica gel is arranged between the side of lid and the groove of side wall, while using the lid and the side wall Pressure silica gel completes the sealing engagement between the lid and the shell, and cover cap, which is connected to shell, can form sealing engagement, saves The process that lid and case lid connect rear subsequent glue or ultrasonic bonding forms sealing has been gone, has improved production efficiency, while can To save corresponding equipment consumption.

Specific embodiment

1~4 the present invention is further described with reference to the accompanying drawing.

The present invention provides a kind of loudspeaker mould groups 100, cover including shell 1 and shell 1 and connect the lid for surrounding accommodating space 3 and the loudspeaker monomer 2 that is housed in accommodating space.

The shell 1 of loudspeaker mould group includes the side wall 11 and bottom wall 12 for surrounding accommodating space, and wherein side wall 11 is from bottom wall 12 extend to form towards the bending of lid 3 direction, and side wall 11 is end to end and is arranged around accommodating space.

In the present embodiment, side wall 11 includes the upper surface 111 opposite with bottom wall 12 and from upper surface 111 to bottom wall 12 Direction is recessed the groove 112 to be formed, the whole upper surface for being wound around side wall in a ring of groove 112.Upper surface 111 is a head and the tail The annular surface to connect.

The lid 3 of loudspeaker mould group is contained in groove 112, and silica gel 4 is arranged between the side and groove 112 of lid 3, Silica gel 4 is hollow ring, and silica gel 4 can be wound around the side of lid 3, may also set up in groove 112.In the present embodiment, Silica gel 4 is circumferentially positioned at the side of lid 3, and silica gel 4 includes main part 41 and corner portion 42, and corner portion 42 is located at main part 41 and leans on The periphery of nearly loudspeaker monomer side 2.Lid 3 and side wall 11 squeeze silica gel 4 complete loudspeaker mould group lid 3 and shell 1 it Between sealing engagement.

In the present embodiment, lid 3, which is contained in the groove 112 of side wall 11 and squeezes silica gel 4 with side wall 11, makes loudspeaking The lid 3 and shell 1 of device mould group are sealingly engaged.In selectable other embodiments, when loudspeaker mould group 100 is mounted directly When on extraneous mounting surface, such as the mainboard of electronic product, the planes such as shell, lid 3 can also be the extraneous peace Dress face, principle is consistent with the lid in present embodiment, is sealed by pressing silica gel.

The fixed part 121 for fixing loudspeaker monomer 2 is provided on bottom wall 12.Specifically in the present embodiment, loudspeaking The side wall 11 of device monomer 2 and shell 1, which is spaced, to be arranged.

Interval forms first operatic tunes 13, loudspeaker monomer 2 and lid 3 between loudspeaker monomer 2 and the bottom wall 12 of shell 1, Second operatic tunes 14 opposite with first operatic tunes 13 is formed between shell 1.

Further, be provided on the side wall 11 of shell 1 to the outside far from accommodating space it is outstanding go out part, part out It is inside provided at least one being connected with first operatic tunes and goes out acoustic aperture 131, in the present embodiment, acoustic aperture 131 is provided with two out It is a.

Second operatic tunes 14 is communicated with the rear operatic tunes of loudspeaker monomer 2, plays the rear operatic tunes for expanding loudspeaker monomer, is improved low Frequency response answers and significantly reduces the effect of F0.In the present embodiment, loudspeaker monomer 2 is magnetic speaker.Loudspeaker monomer 2 It may be other kinds of microphone device, principle is identical.

Loudspeaker mould group of the present invention between the side of lid and the groove of side wall by being arranged silica gel, while described in utilizing The mode that lid engages the lid with the housing seal with the sidewall extrusion silica gel, can be improved the knot of loudspeaker mould group With joint efforts, it eliminates lid and case lid connects rear subsequent glue or ultrasonic bonding forms the process sealed, improve production efficiency, Corresponding equipment consumption can be saved simultaneously.

Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is, example Property, it is not considered as limiting the invention, those skilled in the art within the scope of the invention can be to above-mentioned Embodiment is changed, modifies, replacement and variant.
