The lower section of the position that ring combines.Locating ring serves position-limiting action to the bonding location of ring, it is possible to protect
The concordance of card ring bonding location, and bonding difficulty is low, production efficiency is high.Locating ring is to ring simultaneously
Glue bonding with skeleton serves the effect of barricade, is effectively prevented leakage glue, and glue is distributed evenly,
Bonding fastness is bigger, will not affect the acoustical behavior of speaker because of glue skewness, acoustical behavior
Improve.
Owing to the inwall of shell is provided with the positioning boss of protrusion, U ferrum or the upper surface of washer and positioning boss
Lower surface fix, positioning boss is serving positioning action, improve product conforming also simultaneously
Add the contact area between magnetic circuit system and shell, thus improve the knot between magnetic circuit system and shell
Close firmness, effectively reduce the risk that magnetic circuit system comes off from shell, improve the reliability of product
And service life.
In sum, this utility model speaker solves the concordance that in prior art, speaker ring is bonding
The technical problems such as difference, acoustical behavior difference, this utility model speaker product concordance is good, and acoustical behavior is high,
Production efficiency is high, and reliability is high, and service life is long.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.
The inner side related in this specification refers to the side near Microspeaker center, and outside refers to
The side at Microspeaker center；Refer to be provided with the direction of vibrational system in the orientation related in this specification,
Refer to be provided with the direction of magnetic circuit system under orientation.
Embodiment one:
As Fig. 1 and Fig. 2 jointly shown in, a kind of speaker, including ring-type shell 10, receive in shell 10
