Description
Technical field
The present invention relates to electroacoustic techniques field, particularly a kind of for the speaker unit in portable type electronic product.
Background technology
Along with the develop rapidly of electronic technology, portable electric appts is widely used, speaker unit as acoustical device be electronics standby in an important component part.This speaker unit generally includes the first housing and the second housing that are combined as a whole, and the vibrational system be contained in inner chamber that the first housing and the second housing surround and magnetic circuit system, and vibrational system comprises vibrating diaphragm; The first housing and the second housing is needed to be combined as a whole when having assembled.In prior art, first housing of speaker unit and the combination of the second housing mainly contain following two kinds: first kind of way, as shown in Figure 1, the projection end face that second housing sidewall is inside is fixed with the support ring for fixing vibrating diaphragm, support ring is becket, the overlapping edges of vibrating diaphragm is on support ring, this just makes the first housing cannot weld with support ring, can only be glued, what this was serious have impact on firmness that the first housing is combined with the second housing, speaker unit is made to be easy to ftracture when being subject to impacting, disrepair phenomenon, serious curtailment useful life of speaker unit.The second way, as shown in Figure 2, the weld part of the sidewall of the second housing one to inner process for carrying out welding with the first housing, just need vibrating diaphragm and metal supporting rings to reduce like this when the external dimensions of speaker unit is constant, vibrating diaphragm area reduces the radiation effect that can affect sound, reduce the audio of speaker unit, thus reduce the tonequality of speaker unit.
Summary of the invention
The present invention is directed to above deficiency technical problem to be solved and be to provide a kind of speaker unit, this speaker unit tonequality is good; And mechanical strength is large, strong shock resistance, long service life.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of speaker unit, comprises the first housing and the second housing that combine, contains vibrational system and magnetic circuit system in the cavity that described first housing and the second housing surround; Described vibrational system comprises vibrating diaphragm, and the side at the edge of described vibrating diaphragm is overlapped on the inside projection end face of described second housing sidewall, and the opposite side at the edge of described vibrating diaphragm is provided with the support ring for vibrating diaphragm described in fixed support, and described support ring is plastic hoop; The position of the corresponding described support ring of described first housing is provided with for carrying out the joint portion of ultrasonic bonding with described support ring, and described joint portion extends to described support ring direction.
Improve as one, described joint portion comprises the pedestal be wholely set with described first housing, and the end face of described pedestal is provided with for carrying out the ultrasound lines of ultrasonic bonding with described support ring.
As further improvement, described ultrasound lines is positioned at the centre position of the end face of described pedestal.
As further improvement, described ultrasound lines is positioned at the end face of described pedestal near the side of described second housing sidewall.
Beneficial effect of the present invention is: the side at the edge of the vibrating diaphragm of speaker unit of the present invention is overlapped on the inside projection end face of the second housing sidewall, and the opposite side at the edge of vibrating diaphragm is provided with the support ring for fixing vibrating diaphragm, and support ring is plastic hoop; The position of the corresponding support ring of the first housing is provided with for carrying out the joint portion of ultrasonic bonding with support ring, and joint portion extends to support ring direction.Because support ring is plastic hoop, consistent with the material of the first housing and the second housing, and be positioned at the side of nearly first housing in vibrating diaphragm edge, ultrasonic bonding can be carried out in the joint portion of the first housing and support ring, speed of welding is fast, intensity is high, the intensity of junction can close to raw-material intensity, first housing and the second housing are firmly combined as a whole, when speaker unit is subject to external impacts, cracking or damaged can not be there is easily, add mechanical strength and the impact resistance of speaker unit, extend the useful life of loudspeaker monomer; While ensure that the above-mentioned mechanical performance of speaker unit, also maintain the original size of vibrating diaphragm, thus ensure that the acoustical quality of speaker unit, and then the Integral lifting quality of speaker unit.
Because joint portion comprises the pedestal be connected with the first housing, the end face of pedestal is provided with ultrasound lines, and ultrasound lines is positioned at the end face of pedestal near the side of the second housing sidewall.When carrying out ultrasonic bonding, ultrasound lines is melted, first housing, support ring and the second housing can be combined as a whole, further improve the bond strength of the first housing and the second housing, further ensure that cracking and disrepair phenomenon can not occur when the impact being subject to external force speaker unit.
In sum, speaker unit of the present invention to solve in prior art in conjunction with insecure between speaker unit housing, or must reduce the technical problem of sound effect of speaker unit in order to strong bonded.Combine firmly between speaker unit housing of the present invention, and sound effect is good, long service life.
