Abstract
Изо^^ретение относитс к электроакустике и может использоватьс в качествеголовных телефонов. Цель изобретени - улучшение качества звуковоспроизведени за счет увеличени уровн звукового давлени на требуемых частотах. Головной телефон содержит амбушюр 3 и корпус 2 с перфораци ми. В нем размещены электроакустический преобразователь 1, образующий полость 5 с тыльной стороной корпуса 2, и по крайней мере одна закрыта с одной стороны резонансна труба 7. При этом открытый конец 6 трубы 1 размещен в полости 5. 1 ил.The invention relates to electroacoustics and can be used as head phones. The purpose of the invention is to improve the quality of sound reproduction by increasing the sound pressure level at the required frequencies. The headset includes ear pads 3 and a housing 2 with perforations. An electro-acoustic transducer 1 is placed in it, forming a cavity 5 with the back side of the housing 2, and at least one resonance tube 7 is closed on one side. The open end 6 of the tube 1 is placed in the cavity 5. 1 il.
