Embodiment Construction

[0028] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0029] The inventor first figure 1 The reason why the speaker of the electronic device shown makes the stereo effect poor to the listener has been studied and analyzed, and it is found that:

[0030] When the sound is at low frequency, the sound wave radiation of the speaker is non-directional; as the sound frequency increases, the radiation of the speaker will have obvious directivity. When the sound is in the middle and high frequency bands, the greater the angle away from the 0 degree direction of the speaker axis , the higher the frequency, the stronger the attenuation. When the speaker is placed downward, the sound wave propagates in the 0-degree direction of the front axis, and the listener's ear is not located in the 0-degree direction of the speaker axis, but forms an angle with the speaker, and the sound is...
