Abstract

A miniature sound box with a telescopic resonance cavity. The miniature sound box comprises a loudspeaker, a sound box upper case, a sound box lower case, an audio line, an audio plug, a circuit board, and the telescopic resonance cavity. A loudspeaker mesh is disposed on the miniature sound box. The loudspeaker mesh is disposed on the miniature sound box, a loudspeaker sound through hole is disposed on the loudspeaker mesh, sound spreads outward through the sound through hole, and the loudspeaker mesh is disposed inside the sound box upper case; therefore, the loudspeaker mesh is connected to the sound box upper case, thereby avoiding a direct opening on the sound box upper case. Since the sound through hole is disposed on the loudspeaker mesh and the loudspeaker mesh is then connected to the sound box upper case, processing is convenient, and assembly and disassembly are more convenient and quicker; in addition, the inner loudspeaker can be protected, debris can be prevented from damaging a resonance film of a loudspeaker, and the sound box is protected.

Description

Miniature speaker with telescopic resonance cavity

[Technical Field]

Field of the Invention This invention relates to the field of miniature speakers and, more particularly, to a miniature phase with a telescopic resonance cavity.

【Background technique】

I have applied for a patent for a miniature speaker with a telescopic resonance cavity. The patent application number is 201220404867.X. The miniature speaker includes a speaker, a speaker upper case, a speaker lower case, an audio cable, an audio plug, a circuit board, and a telescopic resonance cavity. . The horn is generally placed in the upper casing of the speaker, and the horn of the horn is indirectly connected to the upper part of the upper casing of the speaker. The sound propagates from the sound hole of the louver through the sound hole, and the upper shell of the speaker has a direct opening for propagating sound. Direct opening makes product processing less convenient.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a miniature speaker which is provided with a sound hole on a speaker net and a speaker net connected to the upper casing of the speaker for convenient processing of the product.

The object of the present invention is achieved by the following technical solutions:

A miniature speaker with a telescopic resonance cavity, comprising a louver, a speaker upper case, a speaker lower case, an audio line, an audio plug, a circuit board and a telescopic resonance cavity, wherein the micro-speaker is provided with a speaker net.

Preferably, the speaker net is pasted on the upper casing of the speaker, which is beneficial to the pasting manner, so that the speaker net and the upper casing of the sound box are processed conveniently, the production is more simple, and the installation is faster.

Preferably, the speaker net is connected to the upper casing of the speaker. The card connection is relatively firm and practical, and the card connection facilitates the removal and installation of the speaker net from the upper casing of the speaker.

Preferably, the upper casing of the speaker is provided with a speaker net placement slot, the edge of the speaker net is provided with a protrusion, and the protruding of the speaker net is placed in the speaker net placement slot. Whether it is stuck or pasted, the set speaker slot is fixed to the connection between the speaker net and the upper case of the speaker, and the sealing of the upper casing of the speaker and the speaker is better. Preferably, the speaker net is provided with a speaker net extending foot. The speaker net extends out to connect to the upper casing of the speaker.

Preferably, the speaker net extends from the upper part of the upper casing of the speaker to the upper casing of the speaker, and the speaker casing mesh slot is provided with a speaker net extending hole, and the speaker net extends through the foot. The speaker net extends out of the hole. Set the speaker net to extend the foot mainly for the card connection. The card connection is to use a plurality of speaker nets to extend the foot and the fixed connection of the speaker upper case. The speaker net extension hole is arranged in the speaker net placement slot to connect the speaker net and the speaker upper case. more convenient,

Preferably, the speaker net extends out of the foot by ninety degrees. It is used for the fixed connection of the speaker net and the upper case of the speaker, and will not shake the bar network.

Preferably, the speaker net has at least two extension legs. Multiples are good for fixing, generally three, and three are relatively strong.

Preferably, the speaker net is circular, the circular shape is convenient for manufacturing, and the sound hole can be arranged to maximize the space.

The invention has a speaker net on the micro-speaker, and a speaker sound hole is arranged on the speaker net, the sound propagates through the sound hole, and the speaker net is installed in the upper shell of the speaker; therefore, the speaker net is connected with the upper shell of the speaker, The direct opening of the upper casing of the speaker is avoided; the sound hole is arranged on the speaker net, and the speaker net is connected with the upper casing of the speaker, which is convenient to process, and is more convenient and quick to assemble and disassemble; Prevent debris from damaging the speaker resonance film and protect the speaker.

The invention will now be further described with reference to the drawings and preferred embodiments.

The micro-speaker with the retractable resonance cavity of the invention, the micro-speaker package, the speaker upper case, the speaker lower case, the audio line, the audio plug, the circuit board and the telescopic resonance cavity, as shown in FIG. There is a speaker net 2 on it. The speaker is usually located in the upper case of the micro-speaker (not shown in the figure), so the speaker net should be connected to the upper case of the speaker. The speaker net 2 is provided with an extension foot 1 , and the upper casing 3 of the speaker is provided with an extension hole 5, and at least two extension legs are generally three, and the three fixations are relatively stable and reliable, of course, other numbers can also be The extending foot 1 passes through the protruding hole 5, and the protruding foot 1 is bent through the upper casing 3 of the speaker and bent ninety degrees for fixing connection with the upper casing 3 of the speaker and fixing the speaker net 2 to be firm and not easy to loose. The connection between the speaker net and the upper case can also be connected by means of pasting. Pasting can make the product more compact and quicker to install.
