Specific implementation mode

Below in conjunction with drawings and embodiments, the utility model is described in further detail.

Please join simultaneously shown in Fig. 1-3, the utility model provides a kind of loudspeaker enclosure 100, including shell 1, sounding monomer 2, Lead sound channel 3, leak holes 4, FPC 5 and support portion 6.

The shell 1 has receiving space (not labeled).In present embodiment, the shell 1 include upper cover 11 and with institute It states upper cover and assembles the lower cover 12 to form the receiving space.

The lower cover 12, which is covered on the upper cover 11 and assembles jointly, surrounds the receiving space.The upper cover 11 and it is described under Lid 12 can be structure as a whole or separate structure.

In present embodiment, the lower cover 12 is laterally away from 11 direction of upper cover recess close to the one of the upper cover 11 Fixing groove 121 is formed, the fixing groove 121 is located at outside the receiving space.

The receiving of sounding monomer 2 is fixed in the receiving space.The sounding monomer 2 separates the receiving space At the preceding operatic tunes 7 and back cavity 101.

Specifically, the sounding monomer 2 be fixedly supported to the upper cover 11 and with the upper cover 11 interval formed it is described before The operatic tunes 7, the sounding monomer 2 surround the back cavity 101 jointly with the upper cover 11 and the lower cover 12.It should be noted that The sounding side (side that vibrating diaphragm is arranged) that the preceding operatic tunes 7 specifically refers to the sounding monomer 2 is surrounded with the upper cover 11.

The sound channel 3 of leading is formed in the receiving space.Specifically, the sound channel 3 of leading is formed in the upper cover 11, it can be an integral molding structure with the upper cover 11.

Ante-chamber (not labeled) is collectively formed in sound channel 3 and the preceding operatic tunes 7 of leading, and will the preceding operatic tunes 7 and the external world Connection is used for sounding；The back cavity 101 is for improving frequency acoustic performance.

The leak holes 4 are connected to through the shell 1 and with the receiving space.

The leak holes 4 specifically run through the upper cover 11 and are arranged and are connected to the back cavity 101, for balancing the back cavity 101 acoustic pressure.

Certainly, the leak holes 4 may also extend through the setting of the lower cover 12, this is also feasible.

The FPC 5 is electrically connected with the sounding monomer 2 and extends to outside the receiving space, for being the sounding list Body 2 introduces external power supply and realizes normal work.In present embodiment, the FPC 5 extends to the receiving by the back cavity 101 Outside space.

Specifically, the FPC 5 includes fixing the first weld part 51 being electrically connected with the sounding monomer 2, by described the One weld part 51 extends and the adjutage 52 that is suspended in the back cavity 101 and extends to the receiving by the adjutage 52 The second weld part 53 outside space.

In present embodiment, the adjutage 52 includes 521 He of the first adjutage extended by first weld part 51 The second adjutage 522 for being connected to second weld part 53 extended by first adjutage 521 bending.The leak holes 4 are oppositely arranged with second adjutage 522.

Second weld part 53 is electrically connected for realizing with the portion source.Specifically, second weld part 53 is fixed In the lower cover 12 of the shell 1.

More preferably, the card of the second weld part 53, which is set, is fixed in the fixing groove 121.The structure facilitates second weldering The fixed installation of socket part 53 improves structural stability when it connect with the external power supply.

The support portion 6 is extended to form from the shell 1 to 52 direction of adjutage protrusion.Described in present embodiment Support portion 6, which is specifically protruded from the lower cover 12 to 52 direction of the adjutage, to be formed.The adjutage 52 is fixedly supported to described Support portion 6.Specially second adjutage 522 is fixedly supported to the support portion 6.

Because the adjutage 52 is contained in the back cavity 101, the interval between the lower cover 12 is smaller, and described The regional gas stream of correspondence in back cavity 101 leak holes 4 is larger (especially opposite with the leak holes 4 in present embodiment The region for second wall extension 522 being arranged), it is easy so that the wall extension 52 of the FPC 5 generates shake, even Cause the shell to generate shell to shake.Therefore after the wall extension 52 fixes support by the support portion 6, it is equivalent to the FPC 5 are reinforced, and the jitter amplitude of the wall extension 52 of the FPC 5 can be effectively reduced, further decrease shell shake risk and because This noise caused, to improve the reliability of the loudspeaker enclosure 100 and improve its acoustical behavior.

The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other relevant technical fields, are equally included in the patent within the scope of the utility model.
