Telephone Parts


Chung Yi Enterprise (HK) Co Ltd makes a full range of RoHS-compliant and UL-approved telephone parts from phone cords to jacks

Hong Kong is one of the largest exporters of basic telephones, cordless phones and mobile phones, all of which require regular supplies of reliable parts and components

Telephones provide a vital means of communication, yet are only as good as the quality of the parts and components used in their design. These parts include speakers, receivers, telephone jacks, microphones, plugs, cords and cables among other basic requirements, and Hong Kong manufacturers use advanced equipment and technology to ensure the parts they supply meet the need.

For example, Dongson Technology Co Ltd has been producing acoustic components since 2004. Its range includes speakers, SMD microphones and buzzers, receivers and digital microphones.

"The whole acoustic component market for high-end mobile phones is dominated by European, American and Japanese companies," explains Sales Manager Chris Liu. "We are probably the only company in Hong Kong that can supply high-grade, small-size, excellent-performance acoustic components."

The FOB Hong Kong unit-price range of Dongson Technology's products is US$0.01-0.70 for microphones, US$0.25-0.90 for speakers, US$0.25-0.50 for receivers and US$0.10-0.70 for buzzers. "We provide a great deal of support in acoustic design and some of the smallest components available," says Mr Liu.

The small components include a 10x15mm speaker, an 8mm receiver and 4mm-square SMD buzzer. "It's the smallest in the world," he comments, referring to the buzzer.

Mr Liu adds that he expects component sizes to continue to shrink in line with advances in phone technology. "Finished products are more sleek and attractive, and the demand from phone designers is for greater miniaturisation and improved sound quality. Interestingly, lots of regular desktop phones are now being designed using mobile phone components."

Production takes place at the company's ISO 9001- and ISO 14001-certified factories on the Chinese mainland and in Korea, using raw materials sourced domestically and from Japan. Delivery is 4-6 weeks after confirmation to major markets in the US, Germany and the mainland. The minimum order is 1,000 items and products are sold under the Dongson Technology brand.

Monthly production capacity is 10 million microphones and buzzers, and five million speakers and receivers. In addition to phones, the firm's components are used in PDAs, Bluetooth headsets, MP3 players and portable electronic devices.

AL Goodwell Industries Ltd, established in 1986, produces a full range of acoustic components and products such as loudspeakers, Mylar speakers, condenser microphones, dynamic receivers, buzzers and transducers and ultrasonic sensors. The firm is now launching its own brand of HD LCD TV products.

"We have talented engineers and designers providing full technical support to our R&D team, which comprises some 100 members. All are well-trained and enthusiastic," says Managing Director Landy Lau.

"Quality control is our first priority," she adds, "and stringent performance tests are conducted using MLSSA instruments from the US in our anechoic chamber room. We also use insulation resistance testers and impedance measuring instruments to test all loudspeakers."

The company has five, 15,000-square-metre factories on the mainland, which produce a wide range of acoustic devices and parts for computers, televisions, toys, security systems, hi-fi and car stereos and telecommunications products. The total workforce numbers 8,000.

AL Goodwell, which uses its own AL brand, is ISO 9001-certified and has applied for ISO 14001.

Major markets are Europe, the US, South America, Australia, Japan and Korea, and goods are delivered 30-45 days after order confirmation.

"All products are developed and designed to cater to the global trend for smaller and thinner, but more sophisticated, products," says Ms Lau.

Jeanleaf Int'l Ltd's products are intended to keep busy lines open and connections strong, and include telephone plugs, jacks, accessories and wires. The company has more than 30 types of PCB jacks on offer, all of which enjoy high demand.

Jeanleaf Int'l supplies buyers in main markets such as Europe, Southeast Asia, the mainland and Hong Kong.

"We expect to see a lot of sales growth in Europe over the next 12 months as we have received a lot of enquiries from potential customers," comments Sales Manager Sam Leung.

Mr Leung adds that most of the firm's customers are attracted to the high quality and competitive pricing on offer.

"We have an in-house plating shop and laboratory, for example, both of which are equipped with advanced testing equipment such as an X-ray machine for gold thickness measurement," says Mr Leung. "These help us to ensure that our products are of the highest quality."

Jeanleaf Int'l operates an ISO 9001-certified, 15,000-square-metre factory in Guangdong Province on the mainland. It sources raw materials domestically, and from Japan and Germany.

The monthly production capacity for its jacks is approximately 500,000 pieces, while the minimum order for these items is 10,000 pieces for delivery 7-10 days after order confirmation.

Mr Leung says that Jeanleaf Int'l is continuously on the lookout for new business and expansion opportunities. "We are actively seeking joint-venture opportunities as well as overseas agents and representative offices."

Clearly, it pays to stay connected to success by partnering with Hong Kong manufacturers of telephone parts.
