The earphone with inverse sound waves includes an earphone housing, a high frequency driver, and a low frequency driver. The earphone housing includes an inner space, a sound output portion, and a reflecting portion. The reflecting portion receives a passive diaphragm. The high frequency driver produces high frequency sound waves and has a sound output direction toward the sound output opening. The low frequency driver is mounted in the inner space of the earphone housing by a mounting brace. The low frequency driver is located between the high frequency driver and the passive diaphragm. A sound transmitting portion is formed between the mounting brace and the earphone housing. The low frequency driver produces low frequency sound waves and has a sound output direction toward the passive diaphragm. The passive diaphragm reflects the low frequency sound waves to the sound output opening via the sound transmitting portion.
