<p>The present invention relates to a beat-frequency wood speaker having a sound amplification unit at the bottom. A base material is formed of pinewood and spruce boards bonded each other. A cellular phone holding groove on which a cellular phone can be put is formed on the upper front portion of the base material. The front of the cellular phone holding groove is open in order for a user to watch a screen in the front. Two speaker grooves of a speaker shape are formed on the front of the base material on the left and right sides, and a beat-frequency groove is formed in the inner center of the speaker groove to form a double speaker groove. A lower sound amplification unit is formed in the lower end of the base material, and therefore the beat-frequency wood speaker has the double speaker groove on the front and the lower sound amplification unit.</p> |
