Description
Technical field
The utility model relates to electroacoustic field, especially relates to household desk folding and unfolding sound equipment (machine), a kind of Microspeaker of electronic toy product.
Background technology
Electroacoustic field of the prior art sound-conducting apparatus, is divided into loud speaker and Microspeaker two class.Loud speaker generally adopts iron-clad support portion, vibrating diaphragm and Φ 32 and with upper magnetic steel composition, volume is comparatively large, tonequality is higher; Microspeaker adopts flat board to mould shell support portion, vibrating diaphragm and Φ 21 and with lower magnetic steel composition, volume is less, tonequality is sharper single.Improve as one, Microspeaker adopts a kind of novel magnetic steel, screw thread waveform plasticity vibrating diaphragm or transparent vibration film and external magnetic type reinforcement to mould shell support portion and is fixed combination.The Microspeaker of traditional structure, in the course of the work, volume is less, tonequality is sharper single; After being subject to external force (extruding or collision or get rid of fall) simultaneously, producing plastic deformation, adverse effect is caused to the reliability of Microspeaker and acoustical behavior.
Therefore, be necessary to improve the Microspeaker of traditional structure, to avoid above-mentioned defect.
Summary of the invention
The utility model solves its technical problem and is to provide a kind of Microspeaker, improves the tonequality of Microspeaker; Strengthen Microspeaker to bear compression set, collide and get rid of and fall deformability; Improve stability and the reliability of Microspeaker.
For achieving the above object, the utility model is by the following technical solutions:
A kind of Microspeaker, comprise vibrating diaphragm, external magnetic type moulds shell support portion and magnet steel composition, described vibrating diaphragm is plasticity screw thread waveform vibrating diaphragm or transparent vibration film, and described external magnetic type moulds outer ring, shell support portion and inner ring center position is provided with reinforcement, and described magnet steel is external diameter φ 27mm metal magnetic magnet steel; Described vibrating diaphragm outer ring and described external magnetic type are moulded outer ring, shell support portion and are fixed, and the inner ring that described magnet steel outer ring and described external magnetic type mould shell support portion is fixed; It is characterized in that: combine closely in the outer ring that described external magnetic type moulds outer ring, shell support portion and described vibrating diaphragm, the inner ring that described magnet steel outer ring and described external magnetic type mould shell support portion is combined closely.
As the preferred technical scheme of one, described vibrating diaphragm is plasticity screw thread waveform vibrating diaphragm or transparent vibration film.
As the preferred technical scheme of one, it is plastic material that described external magnetic type moulds shell support portion, and described external magnetic type moulds outer ring, shell support portion and inner ring center position is provided with reinforcement.
As the preferred technical scheme of one, described magnet steel is metallicl magnetic material, and external diameter is φ 27mm.
The utility model Microspeaker, adopts the novel magnetic steel of φ 27mm, screw thread waveform plasticity vibrating diaphragm or transparent vibration film and external magnetic type to mould shell support portion and is fixed combination.Improve the tonequality of Microspeaker; Strengthen Microspeaker to bear compression set, collide and get rid of and fall deformability; Improve stability and the reliability of Microspeaker.

The utility model Microspeaker as shown in Figure 1, comprises vibrating diaphragm 2, external magnetic type moulds shell support portion 1 and magnet steel 3 forms.As shown in Figure 1, external magnetic type moulds the outside that shell support portion 1 is arranged at vibrating diaphragm 2 outer ring, and vibrating diaphragm 2 is moulded shell support portion 1 by external magnetic type and is combined with the magnet steel 3 of Microspeaker.
As shown in accompanying drawing 2, accompanying drawing 3 and accompanying drawing 5, the outer ring that vibrating diaphragm 2 outer ring and external magnetic type mould shell support portion 1 bonds and fixedly secures, and external magnetic type is moulded 1 pair, shell support portion vibrating diaphragm 2 and played support, protective effect.
As shown in accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, the inner ring that magnet steel 3 outer ring and external magnetic type mould shell support portion 1 bonds and fixedly secures, and external magnetic type is moulded 1 pair, shell support portion magnet steel 3 and played a supporting role.
As shown in the figure, as the preferred technical scheme of one, external magnetic type moulds the outer ring of shell support portion 1 and inner ring center position is provided with reinforcement, increases to bear compression set, collide and get rid of and fall deformability, avoids vibrating diaphragm 2 pressurized, collides and get rid of to fall and deform or break.
As shown in the figure, as the preferred technical scheme of one, vibrating diaphragm 2 is screw thread waveform plasticity vibrating diaphragm or transparent vibration film, fixedly secures the outer ring of moulding shell support portion 1 at external magnetic type.
As shown in the figure, as the preferred technical scheme of one, magnet steel 3 is φ 27mm novel magnetic steel, fixedly secures the inner ring moulding shell support portion 1 at external magnetic type.
These are only the utility model case study on implementation, be not limited to the utility model, as long as those of ordinary skill in the art modify or change according to the equivalence that the utility model institute disclosure is done, all should include in claim and remember in the protection range of cultivation.
