Warehouse & Delivery
A Speaker or Loudspeaker typically offers a wider and flatter frequency response than a piezo, or electro-magnetic buzzer, which is why it is more suitable for applications requiring sound reproduction of music or voice.
Wherever you look today, you will find voice or music quality sound required for user interface, or simply user pleasure at operating many kinds of devices. Today, the largest growth in the loudspeaker industry has been in the area of cell phones and a variety of hand held devices for listening to music, viewing video and a whole variety of utility applications. That is why Esuntech has developed a very large assortment of miniature speakers in every conceivable configuration. In the midsize range Vehicle Telematics, Hands-Free Systems and Park Assist Systems have required dedicated speakers, so that the system can operate independently from the vehicles installed audio system. Larger loudspeaker market growth has been driven mostly by tremendous developments in superior home entertainment systems.
Since the audible spectrum can range from 12Hz to 20 KHz, it is difficult for only one speaker size to capture the entire range. To produce very low frequencies a very large speaker is required, while a miniature speaker can produce higher frequencies with fidelity. This is why high end audio systems often use a multitude of speakers of different sizes in order to capture most accurately the sound being produced, without generating “noise,” or unwanted sound. Esuntech offers a large range of speaker types, from large Sub-Woofers, to very small miniature speakers and lately has introduced a range of surface mount speakers. Surface mount speakers are useful when the electronic assembly process must be entirely automated.
To obtain the best acoustic results, it is generally recommended to get as much loudspeaker as your system budget will allow, whether it is in consideration of available space, power, or money. Please browse our on line selection and for additional models see our Esuntech Standard Speaker, Automotive and Micro-Speaker Catalogs on our web. Please contact Esuntech directly if you require specific application assistance and recommendations of use for a loudspeaker, surface mount speaker or a miniature speaker.
As a single speaker is incapable to provide the whole range of audio frequency so the loudspeaker consists of different driver units which are as follow –
1) Tweeter (for High-frequency range)
2) Mid-range driver (for Middle-frequency range)
3) Woofers (for Low-frequency range)
Types of speaker
The speakers can be classified in many different ways. On the basis of amplification, they can be classified as follow –
1) Passive Speaker
2) Active Speaker
Passive Speaker – The passive speaker does not have built-in power amplifier. So they need to connect to an external power amplifier for high power output. Most speakers that are commercially available are passive type due to their small size.
Active Speaker – This type of speaker has inbuilt power amplifier for high and low frequency. So they are also called as Powered Speakers. But they are bulky as compared to the passive one so they are less used commonly.
Of course, we can provide 2 free samples, and the sample delivery time is 7-10 days.
Please contact us when you need the latest lead time information because it will be changed depend on the market condition.
Please confirm with the sales before placing the order. If there are raw materials in stock, 1,000 pieces of a single variety are acceptable.
Yes,we provide OEM service and can customize products according to the drawing.
Payment terms: T/T, west Union.
