The handset seeks balanced with the micro speaker demand steady long supplier
In the modern handset, the MP3 broadcast, the chord ting, the multimedia movie’s broadcasts, the three-dimensional encirclement sound happy and so on merit can Cheng Weizui sell the spot newly, has provided the infinite power for the micro speaker’s fast development. With the time MP3 player, PDA, the recording pen and so on its it grasped the motion product the rich also thorn to stir up unceasingly to speaker’s demand, this even more thorn has stirred up the micro speaker supplier to the market expectation, their numerous expression will Self Drive Piezo Buzzer expand the output, held the current good opportunity.
But behind the market prosperous picture, the profit which the handset makes declines with the stock pressure is worsening these supplier’s living environment. Along with the miniature speaker’s raw material rise in price, as well as recently the manufacturer market competition, the supplier could also not but simultaneously face comes from various impact. The production centralism has also brought the competition centralism, to win the market, their not only fast response fast changing demand, pays great attention the new product the research and development and necessary, but also emphasizes the product specially the quality guaranteed.
The expanded output as if already did not need the reason, the exuberant demand and did not calculate that the too thin profit entices unceasingly External Drive Magnetic Transducer is producing the manufacturer, to win takes the initiative and the booth thin production cost, the suppliers start from beginning of this year then to always enjoy increase the line to expand produce. Changzhou sound easy to pass electronic Limited company’s General Manager Wu Yifei to indicate that its present monthly output is 3,000,000, the handset uses the speaker is about 500,000. Their planned investment 20,000,000 Yuan use in the production equipment, the slotted line, the workshop and so on, estimated that will expand in the next year first half year the handset with speaker’s monthly output a time.
Shenzhen Hua Baoli electron limited company marketing department Manager Lin Renfeng displays very similarly optimistically: “the communication industry’s demand explosive growth, we will increase 10 ~ 500,000 in the fourth quarter’s output, uses in the Chung handset and non-rope telephone’s section of new 28mm specially ma pulls the speaker.”Shenzhen sea results in prestige industry limited company marketing department’s Zhang Self Drive Magnetic Transducer Guohui also to indicate that this company increased four production lines in October in the view billows, altogether achieves six, in December will put into the volume production.
Shenzhen Ling Jiadian the sound Limited company present handset with speaker’s monthly output is 400 ~ 5,000,000, its marketing department Assistant Manager Li Haipeng thought that at present was the market busy season, the customer aspect had the obvious volume of order growth phenomenon, moreover was the anxious list, they already planned the gain in yield, enhanced produces can the use factor.
Although raw material rise in price already was the recognition, but complete-system vendor pressure as if strong trend, therefore estimated that SMD Transducer the miniature speaker’s price was unable to rise, will continue to decline. The Shenzhen Hua Baoli forest strong front said: “the electro-acoustic system cost will not drop in the complete machine cost’s proportion, will improve possibly also, but the complete machine price’s large decline force manufacturer can not but reduce the speaker product cost with every effort, existing product faced with every year 5~10% reduction scope.”Changzhou sound Yi Tong Wu Yi flies also thought that the price is sliding by the every year 5~10% scopes.
Certainly, the affect price the factor also to have many. The sound electron (Shenzhen) Limited company’s General Manager Li Li analyzed said: “the consumer pursues day after day has the higher performance-to-price ratio handset, will cause the existing product profit space to be smaller, only then the variation market will induct the product only then to have the big profit space.”
Moreover, along with the international electronic processing industry to China’s rapid shift, some overseas’ speaker manufacturer settles down in China in abundance, in addition the native place additional enterprise, intensified the competition situation. Shenzhen Ling Jia Li Haipeng thought: “competition between colleague’s causes the important attribute which the price slides, certainly we also choose according to the market Mechanical Buzzer and the customer situation reduce prices on own initiative.”
For all this, also will have the speaker supplier still the anticipated product selling price to hold in the next half year steadily. The sea results in the prestige Zhang Guohui said: “product, once enters the complete-system vendor the BOM detailed list, in the product quality and in the post-sale service guarantee good situation, the product price is quite stable. We need to digest the material cost rise the pressure, carries on the cost control, maintenance price stability.”
Last year this time, the suppliers warmly were also pursuing hold the complete machine slightly regarding the product, light, the thin urgent demand, actually the opinion varies this year in the size trend of development question. The partial manufacturers positively were still pursuing a smaller size, a bigger
rectangle loudspeaker power, a wider frequency band, another part of manufacturers promote with great effort the reasonable size, guarantees speaker’s high efficiency and the clear exquisite acoustic fidelity.
Changzhou sound Yi Tong Wu Yifei firmly believed that the microminiaturization is the market hot spot. The size microminiaturization has brought in many design techniques and the fabrication technology difficulty. For in the most light-sized situation guaranteed that the output is bigger, the frequency band is wider, the acoustic fidelity is not distorted, the sound easy to cross the adjustment heat resistance performance well entirely, under the high temperature finalizes the degree high, frivolous, the high strength new material, and uses the precision high equipment to carry on the processing production. Sound Yi Tong also launches the cooperation with the German acoustics laboratory, improves unceasingly in the material aspect. Wu Yifei pointed out: “the next several year handset speaker to will paste round loudspeaker the piece type, the microminiaturization, the high efficiency, the wideband direction develops, we next step will develop the two-in-one to paste the piece type product, will use the machine welding to substitute for the manual welding, therefore the request material will have thermostablly, finalizes, the acoustic fidelity displays the good characteristic.”Sound electron’s Li Li also approves this tendency, thought that the speaker must consider how to gather with more and more big handset video frequency part appropriate match, he said: “the sound is aiming at the large screen high-end handset product application research and development miniature rectangle serial products, simultaneously plans the development ellipse two-in-one speaker.”
But Shenzhen sea results in the prestige, Hua Baoli the electron, Ling Jiadian companies and so on sound has the objection to this viewpoint. The sea results in the prestige Zhang Guohui thought that the future product size will not be smaller is better, but should be a quite reasonable size, namely 15/17/18mm. He pointed out that this company has the 10/13/15/17/18/20mm serial products, in which 10~17mm is a circular at present, 18 and 20mm is the ellipse, the 15/17/18mm size also has the two-in-one product. The sea results in the prestige in the market superiority product is precisely some moderate size product, like model and so on HEC1022-01MM, HEC1539-02SM, car receivers HEC1731-02MM, HEC1734-03 miniature speakers. HEC1731-01SM is a section of two-in-one representative the product, at the same time is the speaker, the other aspect may do is the telephone receiver use, realizes the function transformation through line’s cut, may save the space, the reduction of cost. It is said that this product started for handset manufacturer batch goods supplies and so on Kang Jia. It is composed of the 13mm telephone receiver and the 17mm speaker, is 5.2mm highly. .
The Shenzhen Hua Baoli forest strong front indicated: “we do not favor pursue the ultra light-sized product constantly, our research and development direction will also be precisely suits the future product the trend of development: Reasonable light-sized, high efficiency and high performance.”He pointed out that some customers favor not completely ultra light-sized as well as the two-in-one product, the conventional speaker are restricted in the size the deflation, when low frequency the serious distortion, in high frequency is too incisive. “we hoped that seeks for the balance point mini receiver between light-sized and the high acoustic fidelity.”Lin Renfeng also said. Shenzhen Ling Jia Li Hai the huge mythical bird also approves of this viewpoint.
Develops positively has custom-made the new product, multi-channel competes obviously the competitive advantagePursues the great variety of goods not constantly, but is concentrates the development to produce some section of market demand the product, so-called “has the market to do again first”, is the present most enterprises under the fast changeable market situation main research and development strategy, simultaneously may avoid the investment risk effectively, wins the market competition superiority.
Shenzhen sea results in the prestige to research and develop section of 20mm the two-in-one speaker, the contour for the runway ellipse, has high characteristics and so on acoustic fidelity, high power output, high SPL value. This company also specially pays great attention the quality control and the post-sale service, the product fraction defective below 0.05%. Changzhou sound Yi Tong declared that this company’s core competitiveness lies in with the market union very closely, can make the fast response to the customer demand. This company present is researching and developing a section of product for the Simens handset, uses the piezoelectric ceramics to unify the soft membrane way, makes the piezoelectricity type speaker, has a wider frequency band and a thinner Electronic Microphones contour, and has the hearing aid function. In addition sound Yi Tong makes the improvement in the product contour structure’s design, causes it easy to weld and the installment. Sound Yi Tong also in conforms to Europe’s RoHS and the WEEE instruction aspect displays prominently, plans in the year to complete all products the transformation.
Shenzhen Hua Baoli also researches and develops one section to use on the resurgence handset 28×5.3mm ma pulling the speaker, the model is MD028B0A-EE, gradually will form the quantity to produce the scale. This product’s resonance frequency is 500Hz, the impedance 8 (4~300 may elect), power 0.5~1W, SPL value for 88±3dB. Lin Renfeng introduced that the ideal frequency range was in the sounds of people frequency range, namely 120~6000Hz, but multimedia, music, the chord ting enhanced to the sound request this frequency 20000Hz. He pointed out that the pronunciation and music performance is not very same, if wants in guaranteed that under the light-sized premise both proper attention to both, can adopt the compromise way only, or placed hopes in compares a PEI polyester diaphragm more outstanding material.
In the chord ting handset’s coordination, the sound electron is also strengthening with the chip supplier’s research and development cooperation, Micro Microphones makes every effort to unfold the chord ting in the sound the different timbre, each kind of frequency band. “our superiority lies in the independent research and development core part, as well as platform vibrator design and debugging.”
But behind the market prosperous picture, the profit which the handset makes declines with the stock pressure is worsening these supplier’s living environment. Along with the miniature speaker’s raw material rise in price, as well as recently the manufacturer market competition, the supplier could also not but simultaneously face comes from various impact. The production centralism has also brought the competition centralism, to win the market, their not only fast response fast changing demand, pays great attention the new product the research and development and necessary, but also emphasizes the product specially the quality guaranteed.
