下面结合附图和较佳的实施例对本发明作进一歩说明。  The invention will now be further described with reference to the drawings and preferred embodiments.
本发明的带有伸縮共鸣腔的微型音箱， 包括喇叭、 音箱上壳、 音箱中 壳、 音箱下壳、 音频线、 音频插头、 电路板、 喇叭网和伸縮共鸣腔， 所述 喇叭网与音箱上壳做成一体， 音箱上壳上设有通音孔， 通音孔所围成的面 积为圆形。  The micro-speaker with the retractable resonance cavity of the invention comprises a speaker, a speaker upper case, a speaker middle case, a speaker lower case, an audio line, an audio plug, a circuit board, a speaker net and a telescopic resonance cavity, and the speaker net and the speaker The shell is made into one body, and the sound hole is arranged on the upper shell of the speaker, and the area enclosed by the sound hole is circular.
如图 1所示的微型音箱， 在微型音箱的音箱上壳 2上直接设有通音孔 3， 这样就可以省去喇叭网， 不仅可以加快组装的速度， 而且， 还可以节省 材料、 降低成本。 通音孔 3呈圆形， 这样就可以方便制造。 通音孔 3中间 有一圆环 4， 圆环 4四周有多个类似扇形的孔， 越往外部孔就越大， 利于 声音的传播。 另外， 那些类似扇形的孔是对称， 这样就方便制造， 并且美 观。但是， 中间为实心的也可以； 把类似扇形的形状也可以为其他形状的， 像三角形等；孔不对称也是可行的，或把通音孔 3设置为其他形状的可以。  As shown in Figure 1, the micro-speaker has a sound hole 3 directly on the speaker upper case 2 of the micro-speaker, so that the speaker net can be omitted, which not only speeds up the assembly, but also saves materials and reduces costs. . The sound hole 3 is rounded so that it can be easily manufactured. There is a ring 4 in the middle of the sound hole 3, and there are a plurality of fan-like holes around the ring 4. The larger the hole is, the larger the hole is, which is good for the sound. In addition, those fan-like holes are symmetrical, which is convenient to manufacture and beautiful. However, the middle can be solid; the shape resembling a fan can also be other shapes, like a triangle, etc.; hole asymmetry is also possible, or the sound hole 3 can be set to other shapes.
如图 2所示的微型音箱， 微型音箱的音箱上壳 2上的通音孔 3由中心 的两个半圆和外侧的两个半圆环组成， 通过通音孔 3所围成的面积的圆的 中心设置一条俯视图为长方形的类似桥梁的长条 5， 这样刚好把中心通音 孔 3的圆分成对等的两份、 外侧圆环分成对等的两份， 这样不仅可以很好 地固定通音孔 3， 而且， 还可以更好地区传送声音。 但是， 这样固定的通 音孔 3不是太牢固， 于是， 通音孔 3上设置加强筋 6， 加强筋 6通过通音 孔的中心且垂直于长条 5将通音孔分成对称的两部分， 两个半圆被分成四 个扇形， 两个外侧圆环被分成四个， 加强筋 6中间小， 两头大， 这样加强 筋 6就可以更好地增强通音孔的强度， 使其不易损坏， 并且， 便于声音的 传播。 另外， 在加强筋 6上设有 MUSIC, 这可以给人们一种提示， 而且， 还给人美的感觉。 As shown in FIG. 2, the sound hole 3 on the upper casing 2 of the micro-speaker is composed of two semi-circles of the center and two half rings of the outer side, and a circle surrounded by the sound hole 3 The center of the bridge is a rectangular strip-shaped strip 5, so that the center is just right. The circle of the hole 3 is divided into two equal parts, and the outer ring is divided into two equal parts, so that not only the sound hole 3 can be well fixed, but also the sound can be transmitted better. However, the fixed sound hole 3 is not too strong. Therefore, the sound hole 3 is provided with a reinforcing rib 6 which is divided into two parts by a center of the sound hole and perpendicular to the strip 5 to divide the sound hole into two parts. The two semicircles are divided into four sectors, and the two outer rings are divided into four. The ribs 6 are small in the middle and the ends are large, so that the ribs 6 can better enhance the strength of the sound hole, making it less susceptible to damage, and , to facilitate the spread of sound. In addition, MUSIC is provided on the rib 6, which can give people a hint, and also gives a feeling of beauty.
以上内容是结合具体的优选实施方式对本发明所作的进一歩详细说 明， 不能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术 领域的普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若 干简单推演或替换， 都应当视为属于本发明的保护范围。  The above is a detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It is to be understood by those skilled in the art that the present invention can be delineated or substituted without departing from the spirit and scope of the invention.
