  Eclipsing binaries with a $\delta$ Sct component are powerful tools to derive
the fundamental parameters and probe the internal structure of stars. In this
study, spectral analysis of 6 primary $\delta$ Sct components in eclipsing
binaries has been performed. Values of $T_{\rm eff}$, $v \sin i$, and
metallicity for the stars have been derived from medium-resolution
spectroscopy. Additionally, a revised list of $\delta$ Sct stars in eclipsing
binaries is presented. In this list, we have only given the $\delta$ Sct stars
in eclipsing binaries to show the effects of the secondary components and
tidal-locking on the pulsations of primary $\delta$ Sct components. The stellar
pulsation, atmospheric and fundamental parameters (e.g., mass, radius) of 92
$\delta$ Sct stars in eclipsing binaries have been gathered. Comparison of the
properties of single and eclipsing binary member $\delta$ Sct stars has been
made. We find that single $\delta$ Sct stars pulsate in longer periods and with
higher amplitudes than the primary $\delta$ Sct components in eclipsing
binaries. The $v \sin i$ of $\delta$ Sct components is found to be
significantly lower than that of single $\delta$ Sct stars. Relationships
between the pulsation periods, amplitudes, and stellar parameters in our list
have been examined. Significant correlations between the pulsation periods and
the orbital periods, $T_{\rm eff}$, $\log g$, radius, mass ratio, $v \sin i$,
and the filling factor have been found.
