An ear microphone is provided to block echo and howling phenomena by installing an output terminal of a speaker and an input terminal of a microphone so as to be opposite to each other inside a housing. An ear microphone includes a connector(100), and a main body(200). The connector is coupled to an external device. The main body is inserted into a user's ear. The connector is coupled to the main body via a cable(C). The main body includes a housing(210) having an "L" shape, and a speaker(220) and a microphone(230) installed inside the housing. The speaker converts an electrical signal provided from the external device through the connector into a sound signal. The speaker is a balanced armature speaker. The speaker and the microphone are fixed inside the housing by a support member(240). |
