More preferably.
Further arrange：The magnetic cover, main magnet steel and pole piece piece are made by metal material, and by gold between them
The heat bonding connection of category glue.
It is arranged such, because loudspeaker is mainly by the magnetic energy of magnet steel come work, therefore can be with larger using metal material
Degree Shangdi reduces the rejection rate of magnetic induction line, so as to reach more preferable magnetic energy transmission effect, can by the bonding of metal-to-metal adhesive hydro-thermal
The weight of magnetic sheet, is allowed to sensitiveer after largely to mitigate connection, and the audio for reaching is more good.
Further arrange：Dorsad magnetic sheet side is provided with bottom on the body frame, and square opening is provided with the middle of bottom, square opening
Size is identical with the size of magnetic sheet.
It is arranged such, the effect of bottom is to cover magnetic sheet, magnetic sheet is direct with phone housing when preventing loudspeaker from installing
Contact, while bottom can be avoided to stop middle magnetic induction line, so may be used in order to the installation of loudspeaker, the setting of square opening
Further to lift the broadcasting tonequality of loudspeaker.
Further arrange：The bottom is made with body frame by PE plastic materials.
It is arranged such, PE plastics are a kind of aggregated obtained thermoplastic resins of ethene, its odorless is nontoxic, feel ceraceous,
With excellent resistance to low temperature, chemical stability is good, is resistant to the erosion of most of soda acids, and electrical insulating property is excellent, therefore can be with
Largely intercept the impact of other parts loudspeaker in mobile phone.
Further arrange：The voice coil loudspeaker voice coil and magnetic sheet are directly injection-moulded in the groove of body frame, and glue is passed through between bottom and body frame
Water is bonded.
It is arranged such, in groove four magnetic sheets can be avoided to need to be put in four times in groove, greatly reduces operation
The required time, and production efficiency is increased, it is relatively simple connected mode by glue bonding, production efficiency is higher.
Preferably, the magnetic cover is provided with limiting section, magnetic sheet is fastened on body frame by limiting section.
It is arranged such, the setting of limiting section can allow magnetic cover to be fastened on body frame, prevents magnetic sheet activity in use, then
Magnetic sheet is fixed by way of integrated injection molding, so magnetic sheet can be securely fixed, imitated so as to reach better using
Really.
In sum, the utility model has the advantages that：
The magnet steel of five magnetic speakers is more, there is provided magnetic energy it is more sufficient, and the surrounding in main magnet steel surround, can be with
Make the magnetic energy of offer more stable, it is to avoid the magnetic energy that one of magnet steel causes after damaging is uneven, while the enhancing of magnetic energy can
To bring higher performance to loudspeaker, make that the range of loudspeaker is wider, tonequality is better, and result of broadcast is more outstanding.
