Technical field
The utility model is related to electroacoustic conversion art, more particularly, to a kind of vibrating diaphragm and the sounding including the vibrating diaphragm
Device.
Background technology
With scientific and technological fast development, audio frequency apparatus is widely used along with the electronic products such as mobile phone, PAD, computer, and by
Gradually it is known, people also gradually have higher and higher requirement to the audio frequency apparatus effect provisioned in electronic equipment.
Acoustical generator is a kind of device that can convert electrical energy into acoustic energy, belongs to most basic phonation unit.Generally will hair
Sound device monomer is placed in and acoustical generator module is formed in housing, and is positioned in the reserved assembly space of audio frequency apparatus, is formed complete
Audio frequency apparatus.
Acoustical generator monomer is made up of vibrational system and magnetic circuit system in acoustical generator module, can complete basic electric energy conversion
It is the function of acoustic energy.For the generation of acoustic energy, the effect of vibrational system it is critical that.Vibrational system includes:Vibrating diaphragm
And voice coil loudspeaker voice coil, vibrating diaphragm include vibrating diaphragm body and be adhesively fixed on vibrating diaphragm body side center vibrating diaphragm central portion, vibrating diaphragm body it is another
Side is fixed with voice coil loudspeaker voice coil.
As shown in figure 1, in current acoustical generator design, in order to pursue bigger effective radiating area, it will usually will shake
The physical dimension of film central portion is designed as maximizing.But due to the influence of other structures in acoustical generator, it is fixed on vibrating diaphragm body another
The size of the voice coil loudspeaker voice coil of side will be generally less than the size of vibrating diaphragm central portion.This will cause vibrating diaphragm central portion Nian Jie with vibrating diaphragm body
The edge in region is in voice coil loudspeaker voice coil outside.When voice coil loudspeaker voice coil drives diaphragm oscillations, the bonding region on the outside of voice coil loudspeaker voice coil is in vibration processes
In easily come unglued and cause vibrating diaphragm central portion and bonding region and bonding region and vibrating diaphragm ontology hierarchy, produce noise, reduce hair
The acoustic quality of sound device.Particularly compare the four corners position of concentration in stress distribution, easily occur coming unglued layering now in vibration
As.
Based on above-mentioned problem, it is desirable to provide a kind of to mitigate stress concentration, the bonding force of increase bonding region,
The vibrating diaphragm of the problems such as preventing from coming unglued, be layered, to meet people to producing the demand of high-quality acoustic efficiency.
Utility model content
A purpose of the present utility model is to provide a kind of vibrating diaphragm, with solve in acoustical generator vibrating diaphragm product vibrating diaphragm body with
Vibrating diaphragm central portion comes unglued and is layered caused acoustic quality decline, the short problem of service life, another purpose of the present utility model
It is that a kind of acoustical generator including the vibrating diaphragm is provided.
In order to solve the above technical problems, the utility model uses following technical proposals:
On the one hand the utility model discloses a kind of vibrating diaphragm, including vibrating diaphragm body and in the vibrating diaphragm of vibrating diaphragm body center
Centre portion, it is characterised in that the vibrating diaphragm central portion is adhesively fixed with the vibrating diaphragm body, the marginal position of the vibrating diaphragm central portion
Corner be provided with the first breach.
Preferably, the vibrating diaphragm central portion is incorporated into the side of the top non-adhesive voice coil loudspeaker voice coil of the vibrating diaphragm body.
Preferably, the middle position hollow out of the vibrating diaphragm body, edge and the hollow out marginal adhesion of the vibrating diaphragm central portion
Fixed, first breach is no more than the hollow out edge.
Preferably, the vibrating diaphragm central portion is rectangle or Long Circle, and the four corners position of the rectangle or Long Circle sets
It is equipped with the first breach.
Preferably, adhesive is accommodated in first breach.
Preferably, the side long of the vibrating diaphragm central portion and/or short side are provided with multiple second breach.
Preferably, symmetrically it is provided with least one pair of second breach on the side long of the vibrating diaphragm central portion and/or short side.
Preferably, adhesive is accommodated in second breach.
Preferably, the edge of the vibrating diaphragm central portion is fixed with hollow out marginal adhesion, and second breach is no more than described
Hollow out edge.
On the other hand the utility model discloses a kind of acoustical generator, including vibration component, it is characterised in that the vibration group
Part includes the vibrating diaphragm and the voice coil loudspeaker voice coil being fixed on below the vibrating diaphragm;
The voice coil loudspeaker voice coil is located at the inner side at the edge of the vibrating diaphragm central portion.
Vibrating diaphragm body can be formed from vibrating diaphragm central portion by different materials, and vibrating diaphragm body is adhesively fixed with vibrating diaphragm central portion,
During voice coil loudspeaker voice coil drives diaphragm oscillations, the corner of vibrating diaphragm central portion can produce larger stress concentration, so as to cause bonding
Region is susceptible to come unglued, lamination.According to the technical solution of the utility model, set in the corner portion of vibrating diaphragm central portion and lacked
Mouthful, corner positions can be effectively discharged relative to the greater concentration of stress in other regions, it is to avoid cause to shake due to stress concentration
The reduction of membrane body and vibrating diaphragm central portion bonding region bonding force, thus reduce produced when vibrating diaphragm vibrates under voice coil loudspeaker voice coil drive come unglued,
The possibility of layering, extends the service life of acoustical generator.In order to further mitigate bonding region stress concentration phenomenon to vibrating diaphragm band
The influence for coming, can also set multiple breach, with further in the bonding region on the side long of vibrating diaphragm central portion and/or short side
Mitigate the influence of stress concentration.Preferably, acoustic mass is gone out in order to ensure vibrating diaphragm, these breach are tried one's best and are arranged symmetrically on vibrating diaphragm
The surrounding of central portion, with the noise problem that the stability for keeping acoustical generator overall, reduction are caused because structure is asymmetric.Additionally,
By the filling adhesive in breach, the cohesive force of vibrating diaphragm central portion and vibrating diaphragm body can be increased and stress distribution is more divided
