  We assign the scalar tetraquark and the D-wave tetraquark state for $X(4700)$
and calculate the width of the decay $X(4700)$ $\to J/\psi \phi$ within the
framework of light-cone sum rules. The strong coupling $g_{X J/\psi \phi}$ is
obtained by considering the technique of soft-meson approximation. We also
investigate the mass and the decay constant of $X(4700)$ in the framework of
SVZ sum rules. Our prediction for the mass is in agreement with the
experimental measurement, and that for the decay width of $X(4700)$ $\to J/\psi
\phi$ support the possibility that $X(4700)$ could be a scalar tetraquark state
if $X(4700)$ $\to J/\psi \phi$ is the predominant decay channel, or a D-wave
tetraquark state if $X(4700)$ $\to J/\psi \phi$ is not the predominant one and
there exist other decays.
