The invention relates to sound equipment and microphone integrated equipment capable of effectively inhibiting howling. The equipment comprises a shell, wherein the shell is provided with a microphone assembly; the microphone assembly comprises a bi-directional microphone, and the shell is provided with at least more than one loudspeaker; when the one or more loudspeakers emit sounds with the same frequency, the distances of the sounds transmitted to the two pickup ports of the bi-directional microphone are equal, and the vibrating diaphragm of the bi-directional microphone can be in a relatively static state. The equipment has the effects of improving the pickup sensitivity, expanding the pickup angle, improving the sound quality and reducing the squeal influence. 本申请涉及一种有效抑制啸叫的音响麦克风一体设备，其包括壳体，所述壳体设有咪头组件，所述咪头组件包括双指向咪头，所述壳体设有至少一个以上的喇叭，所述一个或多个喇叭发出相同频率的声音时，声音传到双指向咪头的两个拾音口的距离相等，并能够使双指向咪头的振膜处于相对静止状态。本申请具有提升拾音灵敏度、扩大拾音角度、提升声音音质、降低啸叫影响的效果。
