Abstract
The utility model discloses a miniature sound box with a telescopic resonance cavity. The miniature sound box comprises a horn, an upper sound box shell, a lower sound box shell, an audio line, an audio plug, a circuit board and a telescopic resonance cavity; and a horn net is arranged on the miniature sound box. As the horn net is arranged on the miniature sound box, horn sound through holes are arranged on the horn net, sound spreads outwardly through the sound through holes, and the horn net is arranged inside the upper sound box shell, the horn net is connected with the upper sound box shell for avoiding a direct opening on the upper sound box shell; as the sound through holes are arranged on the horn net and the horn net is then connected with the upper sound box shell, processing is not only convenient, but also assembly and disassembly are more convenient and quicker; and the inner horn can be protected, debris can be prevented from damaging the resonance film of a loudspeaker, and the sound box is protected.

Background technology
I have applied for that number of patent application is 201220404867.X in a kind of miniature loudspeaker box patent with flexible resonator, and this miniature loudspeaker box comprises loudspeaker, audio amplifier upper casing, audio amplifier lower casing, tone frequency channel wire, audio jack, circuit board and flexible resonator.Loudspeaker generally all are placed in the audio amplifier upper casing, receive the top of audio amplifier upper casing between the loudspeaker sound mouth, and sound is outwards propagated by continuant orifice from the loudspeaker sender, and the audio amplifier upper casing is provided with direct opening and propagates sound, and it is not too convenient that directly opening can make product processing.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly is arranged on continuant orifice on the speaker net and speaker net is connected to and makes product miniature loudspeaker box easy to process on the audio amplifier upper casing.
The purpose of this utility model is achieved through the following technical solutions:
A kind of miniature loudspeaker box with flexible resonator comprises loudspeaker, audio amplifier upper casing, audio amplifier lower casing, tone frequency channel wire, audio jack, circuit board and flexible resonator, and described miniature loudspeaker box is provided with speaker net.
Preferably, have described speaker net to paste on the audio amplifier upper casing, be beneficial to bonding method, make speaker net and audio amplifier upper casing easy to process, make simpler, install quicker.
Preferably, described speaker net is connected with the clamping of audio amplifier upper casing.Clamping is relatively firm and practical, and clamping is convenient to speaker net from the dismounting of audio amplifier upper casing and is installed.
Preferably, described audio amplifier upper casing is provided with the speaker net standing groove, and described speaker net edge is provided with protrusion, and the protrusion of described speaker net is placed in the speaker net standing groove.No matter be clamping or stickup, the speaker net standing groove of setting all plays certain fixation to the connection between speaker net and the audio amplifier upper casing, and, make the sealing of speaker net and audio amplifier upper casing better.
Preferably, described speaker net is provided with speaker net and stretches out pin.Speaker net is stretched out pin and is used for connecting with the audio amplifier upper casing.
Preferably, described speaker net is stretched out and was worn audio amplifier upper casing top and connect with the audio amplifier upper casing, is provided with speaker net in the described audio amplifier upper casing speaker net standing groove and stretches out the hole, and described speaker net is stretched out and worn speaker net and stretch out the hole.Speaker net is set stretches out pin mainly for clamping, clamping is stretched out pin with a plurality of speaker net exactly and is fixedly connected with the audio amplifier upper casing, and speaker net is stretched out the hole and is located at that speaker net is connected with the audio amplifier upper casing is more convenient,
Preferably, described speaker net is stretched out crooked 90 degree of pin.Be used for speaker net and audio amplifier upper casing fixing stuck, speaker net is rocked.
Preferably, described speaker net is stretched out pin and is at least two.A plurality of being conducive to fixed, and is generally three, and three relatively firm.
Preferably, described speaker net is circular, and circle is convenient to make, and can also be beneficial to greatest extent the spatial placement continuant orifice.
The utility model is owing to being provided with speaker net at miniature loudspeaker box, and speaker net is provided with the loudspeaker continuant orifice, and sound is outwards propagated by continuant orifice, and speaker net is installed in the audio amplifier upper casing; So speaker net is connected with the audio amplifier upper casing, avoided the direct opening of audio amplifier upper casing; Continuant orifice is arranged on the speaker net, and speaker net is connected with the audio amplifier upper casing again, and is not only easy to process, and assembly and disassembly are also more convenient, quick; In addition, play the effect of protecting inner loudspeaker, prevent foreign material damage loud speaker resonating membrane, protection audio amplifier.
