        Micro speaker test

        The speaker is an important component in TV and audio equipment, and also a key component of audio communication products (e.g. telephone and mobile phone). Its quality directly affects the sound quality of such products. Micro speakers are generally used in small-sized electroacoustic devices, such as earphones. They are directly related to the hearing of ears. The micro speaker test solution provided by CRYSOUND is compatible with a variety of speaker units, such as balanced armature speaker and moving-coil speaker, and can fully meet customers' requirements for product test items. Special test fixtures can be customized for speaker units including the front cavity of the headphone. This enables fast and stable testing.
