Abstract
The utility model relates to the electroacoustic apparatus field, in particular to a detachable vibration group for a loudspeaker. A spherical distal membrane and a vibrating edge of the integrated vibrating group of the prior small loudspeaker are fabricated separately and then bonded. The detachable vibration group consists of a spherical distal membrane, a voice coil, a pressing ring and a vibrating edge, and also comprises a support, a binding post and a fastening screw. The spherical distal membrane is arranged at the center of the detachable vibration group, and the voice coil and the vibrating edge are shown from inside to outside. The vibrating edge is clamped by the aluminum pressing ring with upper and lower layers and bonded and fixed on the support. The inner diameter of the voice coil is bonded to the spherical distal membrane, and the external diameter of the voice coil is stuck to the vibrating edge. Because the separate fabrication is carried out and the vibrating wave in vocalization vibration is partitioned into two parts, large vibration moment is not produced. The adhesive contact surface among the voice coil, the spherical distal membrane and vibrating edge is increased relatively, and the internal factor of degumming is decreased, so the degumming is not easy. Moreover, the utility model is also not caused heating, cracking and other phenomena of the voice coil, so the sound quality is kept clear, and the life time of the product is also prolonged relatively.
Description
Technical field
The utility model relates to the part field of electroacoustic apparatus, specifically refers to a kind of separate type vibration group of miniature loudspeaker.
Background technology
Present domestic especially a kind of traditional little loud speaker of small-power loudspeaker with ball top type vibration group, its ball teleblem is the same body structure that connects together with the vibration ring, and directly to use bonding voice coil loudspeaker voice coil of neutral gum and skeleton, its defective of loudspeaker vibration group of this form be that insecure and temperature tolerance is poor.In frequent vibration, easily produce tired and come unstuck, ball teleblem and voice coil loudspeaker voice coil are come off, influence its sounding and useful life.Though so thing is little, have a strong impact on the quality of product, it is necessary therefore this type of ball teleblem being improved with the vibration group of vibration ring consubstantiality.
The utility model content
The purpose of this utility model is: the consubstantiality formula vibration group of at present traditional little loud speaker is carried out some improve, with the interior quality and the useful life of improving little loud speaker.
The technical scheme of the utility model technical solution problem is: ball teleblem in the consubstantiality formula vibration group of existing little loud speaker and vibration ring are carried out separating making, and then carry out bonding, its objective is that the stress when making vibration reduces, the bonding contact area of ball teleblem and voice coil loudspeaker voice coil is increased, make voice coil loudspeaker voice coil be difficult for coming unstuck.The utility model is made up of ball teleblem, voice coil loudspeaker voice coil, trim ring and vibration ring, also comprises support, binding post and trip bolt.Described separate type vibration group is characterized in that: central authorities are ball teleblems that platinum/titanium metal thin film is made, and are voice coil loudspeaker voice coil, vibration ring from the inside to the outside successively, the trim ring clamping of two-layer aluminum up and down of described vibration ring quilt, and be adhesively fixed on the support.The internal diameter of described voice coil loudspeaker voice coil and ball teleblem are bonding, and external diameter is bonding with the vibration ring.Be provided with two audio-frequency electric streamlines symmetrically on described voice coil loudspeaker voice coil outer rim both sides, and be electrically connected with binding post.
Described binding post and support are fixed with trip bolt.
What the utility model was useful is because the ball teleblem separates with the vibration ring, the ripple that shakes during its sounding vibration is separated into two parts, therefore can not produce big oscillatory torque, simultaneously voice coil loudspeaker voice coil and ball teleblem and vibrate relative increase of gluing contact-making surface between the ring, reduced the internal factor of coming unstuck, therefore be difficult for coming unstuck, and because ball teleblem and the split of vibration ring, can not produce big vibration when therefore sounding vibrates and cause phenomenons such as voice coil loudspeaker voice coil heating, cracking, thereby the tonequality that makes loud speaker keeps clear, and the life-span of product also prolongs relatively.

Fig. 2 is a broken away view of the present utility model;
Each title and mark among the figure: 1. binding post, 2. trim ring, 3. voice coil loudspeaker voice coil, 4. ball teleblem, 5. audio-frequency electric streamline, 6. support, 7. vibration ring, 8. trip bolt.
Embodiment
As shown in Figure 1, 2: the utility model is a kind of follow-on miniature loudspeaker, and it is to carry out improved a kind of new product at traditional ball teleblem and vibration ring on the loud speaker basis with body structure.Ball teleblem in the consubstantiality formula vibration group of existing little loud speaker and vibration ring are carried out separating making, and then carry out bonding, its objective is the stress of ball teleblem when vibration sounding is reduced relative increase of gluing contact-making surface between voice coil loudspeaker voice coil and ball teleblem and the vibration ring.The utility model is made up of ball teleblem 4, voice coil loudspeaker voice coil 3, trim ring 2, vibration ring 7, also comprises support 6, binding post 1 and trip bolt 8.Central authorities are ball teleblems 4, are voice coil loudspeaker voice coil 3, vibration ring 7 from the inside to the outside successively, trim ring 2 clampings of two-layer aluminum up and down of vibration ring 7 quilts, and be adhesively fixed on the support 6, support 6 two ends are provided with binding post 1 and trip bolt 8.The internal diameter of voice coil loudspeaker voice coil 3 and ball teleblem 4 are bonding, and external diameter is bonding with vibration ring 7.Be arranged with two audio-frequency electric streamlines 5 on voice coil loudspeaker voice coil 3 outer rim both sides, and be electrically connected with binding post 1.
